Comparison of various refrigerants (R-410A, R-22, R-32, R-290, R-134A, R-600A) used for Air Conditioners and Refrigerators

By on August 7, 2017

While growing up in the 1990s I used to hear a lot about CFCs (or chlorofluorocarbons) and their involvement in depletion of ozone layer. There were talks that all the refrigerants that cause environmental harm will be phased out. But as the years passed by, the thought of checking if a refrigerator or air conditioner that is being purchased has environmentally friendly refrigerant or not, vanished, as the presumption was that the CFCs have been phased out and we only get environmentally friendly refrigerants these days. But is that true? Or do we really care? In this article, we will look at various refrigerants that are used in air conditioners and refrigerators that are available in Indian market.


What is a refrigerant?

A refrigerant is a fluid that is used in air conditioners and refrigerators, to take heat from the contents of a refrigerator or the room (in the case of ACs) and throw the heat out in the atmosphere. A refrigerant undergoes phase changes from a liquid to gas (on absorbing heat) and back to liquid (when a compressor compresses it). The choice of ideal refrigerant is made based on its favorable thermodynamic properties, non-corrosive nature, and safety (non-toxic and non-flammable). Although many fluids can be used to act as a refrigerant, but in 20th century, CFCs became the most popular refrigerants.

Old and Modern refrigerants

The most common refrigerant in the past was a CFC, most commonly called as Freon. Freon was a brand name for a refrigerant “R-12” by DuPont.  In the 1990s and 2000s, the CFCs were replaced with HCFCs (hydrochlorofluorocarbon) and the most common HCFC is “R-22”. 50-60% of Air Conditioners in India still (in 2016) use HCFCs. However, HCFCs are just marginally better than CFCs as they contain chlorine, which is harmful for the environment. As per Indian Government’s plan, HCFCs will be phased out from India by the year 2030.

To remove chlorine from the refrigerant, manufacturers created another set of refrigerants called HFCs (or Hydro Fluro Carbons). Although they also have the potential for global warming, but still they are better than HCFCs as they do not deplete the ozone layer. The most common HFC used in air conditioners is R-410A. This refrigerant is better than R-22 in terms of “Ozone Depletion” potential and energy efficiency, but it still causes global warming. A few more HFCs that are commonly used are: R-32 in Air Conditioners and R-134A in refrigerators. About 20-30% of the air conditioners in India still (in 2016) use HFCs. R-32 is better than R-410A in terms of global warming potential, but then it is still an HFC. As per latest news, India plans to phase out HFCs as well in next few years, and the timeline for it is still under consideration.

The most environment-friendly refrigerants that are available in Indian market currently are “R-290” and “R-600A”. They are HC or Hydrocarbons, and their chemical names are “Propane” for R-290 and “Iso-Butane” for R-600A. They are completely halogen free, have no ozone depletion potential and are lowest in terms of global warming potential. They also have high-energy efficiency but are highly flammable as they are hydrocarbons. But they are the greenest refrigerants in the market. Manufacturers, who use these refrigerants, claim that they have taken good care in using these refrigerants and the appliances are absolutely safe. In fact, most refrigerators in the Indian market are now on R-600A and there are no reported incidents of any accidents due to the same. So we can comfortably believe that they are safe.

Below is the data for Global Warming Potential of various refrigerants (source):

RefrigerantGlobal Warming PotentialOzone Depletion Potential
R-221810Medium
R-410A2088Zero
R-32675Zero
R-134A1430Zero
R-2903Zero
R-600A3Zero

Conclusion

If you are someone who cares about energy efficiency and global warming, go for an Air Conditioner with R-290 or a Refrigerator with R-600A. The more you opt for it, the more the manufacturers will start using them in their appliances. Hopefully, with stringent standards and better advancements in technology, we will be able to see better refrigerants in future.

Thank you for fast reply.
As per room size 0.75 ton capacity enough for me? Shall i go with inverter AC?

Abhishek Jain (Mod)

It will certainly be better if you go for Inverter AC.

Hi Abhishek and Manisha!

I am at Alliance for an Energy Efficient Economy (AEEE) - you are on the AEEE closed group on LinkedIn. We are doing a deep dive into India's cooling demand in 2017 and 2027 - for this Bijli Bachao is most useful. I have some specific questions for you:

1. You mention the best RAC models here - but which ones are most prevalent by sales volume? This can help us make a pie of the current refrigerant base in RACs in the present year.

2. I also wish to know your sources for all this info - this will help us cite in our reports.

Sir,
Thank you very much for so fast reply.

Please suggest me good inverter ac of 1.5 ton with 3 star.

Thank you sir.

8
Abhishek Jain (Mod)

If you prefer Hitachi as a brand, then I think Hitachi models are the most energy efficient and feature rich. You can go for them.

9

Sir,

Hitachi 1.5 Ton 3 Star Waza 3200i RSD318EAEA Inverter Split Air Conditioner
Hitachi 1.5 Ton Inverter (3 Star) Split AC - White (RSI/CSI/ESI-318EAEA, Copper Condenser)
Onida 1.5 Ton Inverter Split AC - White (INV18GDR, Copper Condenser)

From above three, which AC should i buy?
or suggest some other brand or model also similar to above models.
( I want 1.5 ton inverter 3 star from onida or hitachi brand only )
Thank you sir.

10
Abhishek Jain (Mod)

If your choice is limited to Onida and Hitachi then you do not have too many options. I think Hitachi 1.5 Ton Inverter (3 Star) Split AC – White (RSI/CSI/ESI-318EAEA, Copper Condenser) would be a better choice for you.

11

Hi i am looking for an inverter split ac for my room for 1.5 ton 5 star.
hw's daikin inverter split ac company?
also please tell me review of daikin model jtkm50srv16?
or please tell me which company inverter split ac is better for home usage?

12
Abhishek Jain (Mod)

Hi Inderjit,

DAIKIN-JTKM50
HITACHI-RSA518CAEA
GODREJ-GSC 18 GIG 5 DGOG (Flipkart Link: http://fkrt.it/wYdlq!NNNN )
BLUESTAR-5CNHW18PAFU (Amazon Link: http://amzn.to/2vLJKXv )

are the most energy efficient BEE 5 star rated inverter AC. Daikin JTKM50 is a good AC with high energy efficiency and great air filters (so air purifier is built in).

13

Hi! I am looking to buy around 6 split ACs for my 14th floor penthouse. Now, as the house is going to be on 14th floor I will need an AC which can withstand the high temps and provide fast cooling. Features like inbuilt air purification will also be appreciated. If budget is not a concern which, according to you, is the best split ac (preferably 1.5 TR)? I have so far selected Panasonic Sky Elite Series, Blue Star Precision P Series, Daikin JTKM, Carrier Superia 365/Octra 5i and Mitsubishi GE/GK/GN.

14
Abhishek Jain (Mod)

Hi Purav,

Faster cooling depends on cooling capacity of the AC. If you put a 2 ton AC in a small 100 sq ft room it will cool really fast (because the heat inside a 100 sq ft room is less) .... this is because cooling capacity of 2 ton AC is high. And the same 2 Ton AC will not cool a 400-450 sq ft room fast enough because the room size is huge. Another senario is if you fill in a 100 sq ft room with 50 people, the same 2 ton AC will not cool fast enough. Because every human releases heat and the AC is not big enough to cool it.

To give you an analogy, put one person on a 100 cc bike, it moves decently fast, put two on that, it will be slower, put 3 on that , it will move further slow, and keep increasing number of people, the bike cannot take the load. A car with 1 person will move really fast, with 4 people it will work decent, put 20 people in a car, the motor will not be able to take load.

It is very important to size AC properly to realize right cooling. I would suggest that you use the calculator on this site to find the right tonnages for your rooms. You can get the calculator on this link: https://www.bijlibachao.com/top-ten-appliances/best-air-conditioner-ac-window-split-hitachi-lg-carrier-samsung-electricity-consumption-tonnage-in-india.html

Another point to note is that not every 1.5 ton AC in market provides 1.5 ton cooling capacity. 1.5 ton is just the marketing cooling capacity. 1 ton is 3504 Watts. So 1.5 ton should be 5256 watts. But if you go in market and check the cooling capacity (in watts) of all the 1.5 ton ACs, you will find a great variety. Some will be 4800 watts, some 4900, some 5000 and some 5100 and some even 5300. So in that sense a model with 5300 will certainly cool faster.

Your next requirement is that the AC should withstand high temp. How high will be the temperature? Most ACs in the market can work at about 46 degrees at least. Brands like Mitsubishi Heavy have come out with models that can work even up to 56 degrees. But then they are required only if the temperature goes really high in your city. If you are in Delhi then buying AC with operating temperature of 46 may not be the right thing to do. But if you are in Mumbai where peak summer temperature is 34-35, any AC can work.

If you mean to say that your ceiling gets a lot of sunlight and so the rooms get hot, then that should be counted in the cooling capacity of the AC, and the calculator on this site can help you find the right tonnage for your rooms. Please select the right tonnages for your room and I can suggest you good ACs for the same.

hi am arun,
i want to knw abt which refrigerant can be compressed easily & (in less than 3 bar)..

16
Abhishek Jain (Mod)

Hi Arun,

I am sorry I am not aware of the same.

17

Hi Abhishek,

I am planning to buy Voltas 1.5 ton split AC with Copper condenser. I see that there are 2 models - JY 183 which has R22 gas and LY 183 which has R410 gas. While I understand that R410 is more eco-friendly, I read somewhere that in case the R410 gas leaks it is very difficult to refill it and that it also costs 3000-4000 for a refill. Do you have any idea about it ?

Also I would like to know if I buy the model with R22 gas and if in case it's banned in future, will the same equipment be compatible with R410 gas ?

18
Abhishek Jain (Mod)

A system with R410 gas has a very different design as compared to a system with R22. So I do not think you will be able to fill the model with R410A without changes. It is better to go for R410A gas.

19

Thanks for the reply. But are you aware of any complications (technically & cost-wise) in refilling R410A gas in case it leaks.

20
Abhishek Jain (Mod)

R410A is a high pressure refrigerant whereas R22 is a low pressure refrigerant. The copper wall thickness of the tubes needed is different as the tubes need to handle higher pressure in case of R410A. A model that has R410A can be filled with R22, but not the reverse. I am not aware of the cost wise difference.

21

Dear abhishek jain
Sir I want to buy 1.5 ton 3 star split AC upto 30k. Required copper condenser and durable product. Dont want to go for look but want a solid device. Also want a good after sale service. M residing in Amritsar.Thanks.

Hi, am looking at Whirlpool brand neo double door Refrigerators .Cannot get specs on what refrigerant they are using.
Could you please inform in this regard.
Which double door/invertor fridge models in India are coming with non/less flammable refrigerant.

Thanks

24
Abhishek Jain (Mod)

Hi Kumar,

Whirlpool does not mention the refrigerant on the specs (but the information may be available on the model body itself as per whirlpool website). But most brands use either R134A or R600A as refrigerants. Firstly, ALL REFRIGERANTS are FLAMMABLE. You cannot get a non flammable refrigerant. Also most energy efficient refrigerants are most flammable because they are hydrocarbons. If you go for a less flammable refrigerant, you will not get an electricity saving refrigerator. R134A is HFC (or Hydro Fluoro Carbon) and R600A is HC or Hydro Carbon. HCs are more electricity saving, less environment harming, but are highly flammable. But having said that, you also keep a LPG cylinder in your house which is flammable. Just like protection is there in LPG cylinders, protection is there in refrigerators. It does not happen that refrigerators blast every day just because they have a refrigerant. Also the quantity of refrigerant in refrigerators is much less as compared the quantity of LPG in LPG cylinders.

sir i purchased voltas 1.5 ton A.c inverter technology with 3 stars . I have an issue with my machine at starting it takes 9.5 ampere and minimum 4 ampere it doesn't descend behind 4 ampere . Is there any fault in my machine because my relatives uses the same A.C but without inverter technology and their A.C consumes minimum 2 ampere and I roughly used it for 25 days for 8 hours daily the amount contribute to my electricity bill by this a.c is 4000rs only for a.c not by my household other appliances. Sir please help me regarding this, is it defective piece given by dealer to me

27
Abhishek Jain (Mod)

Looks like a problem with the AC. It could be installation problem as well. You should contact the dealer.

28

Hi BB team,
Recently I heard from a shopkeeper that R32 is more inflammable than R22. Is this true ? How can we get the correct data on which device uses which gas ?

-Ankur Jain

29
Abhishek Jain (Mod)

Hi Ankur,

R32 is certainly more flammable, but then most people keep LPG cylinders as well in their house. And LPG is also flammable. Precautions are taken when building machines that have such refrigerant. In fact R290 has similar chemical formula as LPG. And it is the greenest refrigerant in the market. R290 is A HC (or Hydrocarbon). And it is the most energy efficient and refrigerant with lowest harm to the environment. World over manufacturers are moving over to HCs as refrigerant. In fact in India R22 will be phased out by 2030 and government is putting a plan to phase out HFCs (R401A and R32) as well (source: http://timesofindia.indiatimes.com/home/environment/global-warming/In-Rwanda-India-to-seek-just-deal-on-phasing-out-of-HFCs/articleshow/54549884.cms ).

Many manufacturers mention the refrigerant they use for the models. In fact if it is R410A, R32 or R290 then they do mention it in specs. If nothing is mentioned then it is most likely R22.

Dear Bijli bachao team,
Your portal is really good and also kind of pride of India because of are thinking at greater level.
I have recently purchased Sansui 1.5 ton 3 star inverter AC with ISEER of 3.77. It's only available from Flipkart. It's working fine till date.
It doesnt have fancy option but has R410A and Copper condensor as well.
Most reviews on facebook are positive only.

Hope this is good choice.

31
Abhishek Jain (Mod)

Hi Anurag,

Firstly, I must say products of all brands worth their salt will work. Sansui is a decent brand and there is no reason for their AC to not work. It is not a popular or premium brand, but that does not mean that it will not work. They have used pretty good specs for their AC and the pricing is quite competitive, so it is a very attractive deal.

However, as I said it is not a popular or premium brand, it will take its own time to prove itself in AC market. Brand value includes a lot of things: 1) High probability of good quality 2) Good engineering (so that the product performs efficiently for a long time) 3) Most top brands have good specs for most models. But then you also have to pay premium for premium brands.

I would not say that Sansui is the best quality product out there. But then it has worked well for a lot of people (and thus positive reviews on Flipkart). So I would surely give it a chance (based on collective trust), as the specs look good. Especially if I am willing to test out a new brand.

32
Anurag Aggarwal

Thank you Abhishek for reply. Below is the link to the Sansui AC. I agree that premium brand makes higher quality more probabilty. Other copper ACs are around 10k more costlier which is huge.

https://www.flipkart.com/sansui-1-5-ton-inverter-3-star-split-ac-white/p/itmerekmf3swwzcr

If you can review it, it will be great. It will give people a cheaper alternate for inverter AC. I have purchased as per specs only and took a risk. I have seen Voltas AC PCBs also failing within 3 months of purchase.

33
Abhishek Jain (Mod)

Hi Anurag,

Based on specs and initial usage feedback, this model looks absolutely value for money. It may not have high end features, but then for basic cooling and efficiency it looks good. But durability and derating shows up with time and it is difficult to review that. Because a lot of it depends on how well the product is engineered. But based on the initial feedback, it looks quite value for money.

34

Thank you Abhishek for your time and comments. Probably after a season's run, i will report back about performance and reliability.

35

Hi Abishaek,

I would like to buy an AC for my living room.
Requirement : 1.5 Ton AC
Refrigerant : R-410A or R-290 ( but strict no to R-22)

Room size: 11*12 but planning for 1.5 ton only for nearby room cooling

Budget: 30K to 35K

Model needed: Voltas,Bluestar,Hitachi, diakin

Please suggest suitable brands.
Location:Chennai

36
Abhishek Jain (Mod)

Hi Hari,

ACs usually have limited reach and cannot cool nearby room unless there is good enough air circulation. There are ACs with long air flow, but then to size you need to take area of both the rooms into consideration. ACs do not work like air coolers. ACs need closed area to cool the space.

37

I understood what u said. I have one query. Can u suggest me some new reliable models (2017) which has r410A refrigerant / r290 within 40K. (Can be 1 ton or 1.5 ton) no issues

38
Abhishek Jain (Mod)

If you can increase your budget to 40K then you can surely get models with R32 (equivalent and slightly better than R410A) and R290.

Daikin FTF35 (1 ton with R32) (Flipkart Link: http://fkrt.it/Wt05N!NNNN , Amazon Link: http://amzn.to/2ukkvfj )
Blue Star 5HW12ZAWTX (1 ton with R32) (Amazon Link: http://amzn.to/2tbXmNH )

Godrej GSC 12 FG 8 MOG (1 ton with R290) (Amazon Link: http://amzn.to/2tHb9fL , Flipkart Link: http://fkrt.it/lABzVTuuuN )
Godrej GSC 12 FG 6 ROG (1 ton with R290)
Godrej GSC 18 FG 6 BOG (1.5 ton with R290) (Amazon Link: http://amzn.to/2tH1Mg8 )

In Blue Star you can also check 5HW18SBTU or 5HW18ZBRTU or 5HW18ZBWTU in 1.5 ton and 5HW12SBTU or 5HW12ZBRTU or 5HW12ZBWTU in 1 ton. I am not sure of the price of these models, but these are the best.

There are very few non inverter ACs with better refrigerants. Most inverter ACs have better refrigerants.

39

Hi Abishaek (Mod),

I have checked the above models. I don't know why people don't buy these products. Most of the above mentioned products have 2/5 reviews especially in amazon.

Also does inverter AC's are worth when it is used for 6 hours a day. Meaning 30*6=180 hours a month.Since in inverter ac's, compressor runs 30% continuously hence it would be very useful if it is used for 12-15 hours a day.

So i am looking for new 2017 branded model 1.5 ton 5 star non inverter split AC copper condensor (R290 or R32 or R410A refrigerant) with minimum 4/5 rating in 40k budget (:P)

40
Abhishek Jain (Mod)

Hi Hari,

Inverter ACs will save electricity even if you use it for 1 hour. Because the compressor speed varies as per the requirement of the room and thus the power consumption also varies as per the speed of the compressor. It is a myth that it will be useful only if it is used for 12-15 hrs a day. People have used Inverter ACs and have seen benefit.

I would suggest you to check BlueStar 5 star models or Daikin 5 star models if you want 5 star non inverter Split ACs with 4/5 star rating in 40K budget. I think Blue Star would be the best for you (as I doubt Daikin will fit in that budget). Voltas models would be your next best choice.

41

Please suggest non inverter type split ACs because we use only for 5-6 hours a day

42
Abhishek Jain (Mod)

I would suggest that you do right tonnage calculations for both the rooms using the calculator on this page: https://www.bijlibachao.com/top-ten-appliances/best-air-conditioner-ac-window-split-hitachi-lg-carrier-samsung-electricity-consumption-tonnage-in-india.html

43

I understood what u said. Now i am planning to go for 1 ton AC. But Y all the new models(2017 models) in AC's especially voltas and many more comes with refrigerant R22 when it causes huge harmful effects to ozone and it is likely to be phased out within 2020

44
Abhishek Jain (Mod)

Hi Hari,

The phaseout date is not 2020 but is 2030. And I agree with you that they should remove R22 but costs play a major factor when models are made for India. India is a very cost conscious country and cheaper models sell the most. A lot of people buy ACs on Flipkart that are available for Rs 18000/19000.

By the way I checked 1 and 1.5 ton models in your budget of 30-35K and I found that Voltas 125 ZY (R410A) or Voltas 185 ZY (R410A) would be the best buy for you. They are not available on Amazon or Flipkart but then you can get them on Tata Cliq (Tata's ecommerce site). Premium brands (like Hitachi, Daikin, etc) have expensive BEE 5 star rated models. You can get a few Panasonic or Carrier models in 1 ton but then they do not have R410A. So the voltas models would be the best. Also please make sure that you check the tonnage required using the tonnage calculator on this website.

45

I totally agree with you abisheak. But both the Zenith series models of voltas have been launched in 2015(bit old model). 1 ton is 30k and 1.5 ton is 40K. But i am looking for new models ( 2017 launch models) with r410A or R290 or R600A within 35K (:P)... But godrej models 1 ton itself starts with 44K for R290 refrigerants with moderate reviews in amazon ( :( ). I dont prefer R-32 because i read that it is highly flammable. So i am avoiding it. Please suggest some new models please if u know it within my budget range

46
Abhishek Jain (Mod)

And by the way ultimately everything will have to move to R290 because as par of first phase of phaseout HCFCs are being removed. R22 is HCFC. And the second phase will be for phasing out HFCs (R410A and R32 are HFCs). R290 is a HC or Hydrocarbon. The world is moving towards using HCs (or hydrocarbons) as refrigerants. Many countries are in process of phasing out HFCs right now.

47
Abhishek Jain (Mod)

Hi Hari,

R290 is more flammable than R32 as chemical formula for R290 and LPG is the same. But they take good care to make sure that refrigerant is safe. We also keep LPG cylinders in our houses and they are safe.

48

Thanks in advance for the suggestions

49

Hi Abhishek,
I want to buy AC for my living room which is connected to dining room. Approximate area is 350 sq. feet. I have selected Mitsubishi brand. can you suggest me which model is having R-32 as refrigerant in mitsubishi? or you can suggest me other brand considering efficiency and power consumption.

50
Abhishek Jain (Mod)

Hi Nitu,

To cover larger area Mitsubishi Heavy Industries would be the best brand as they have long air flow. They use R410A which is comparable to R-410A if not better (as both are HFCs). You can go for Mitsubishi Heavy SRK25CSS-S6 (link: http://www.iaplgroup.com/srk20css-s6_srk25css-s6.php ) ... I think this would be the best option for the room.

51

When is R22 refrigerant likely to be phased out?
What is likey to happen to the A.C.s with R22 ?

52
Abhishek Jain (Mod)

By 2030. Slowly number of ACs with R22 will also reduce.

53

Do we have any Hitachi Split A.C model with R 32 refrigerant ?
I need to buy preferably 1.5 ton with 5 star rating.
Is Inverter A.C. better than regular A.C.? If yes, why?

54
Abhishek Jain (Mod)

Inverter AC is better and this link can answer your questions: https://www.bijlibachao.com/air-conditioners/what-is-inverter-technology-air-conditioner-and-how-it-is-different-from-bee-5-star.html

Hitachi does not use R32. Hitachi uses R410A.

There are BEE 5 star rated inverter ACs and non inverter ACs. The non inverter BEE 5 star rated ones are equivalent to BEE 3 star rated inverter ACs. You have to choose one based on your usage and budget.

55

Hi Abhishek,

I am living in Jaipur. I am planning to buy 1.5 Ton Split Inverter AC. I did a little research after reading your articles and zeroed it on Daikin (JTKM series ) and Hitachi (Kashikoi 5400i). I read about both of them and found Daikin to be more energy efficient. Previously I was going for Ogeneral Inverter AC but after reading your many articles I would like to go for ACs which are energy efficient. So no more Ogeneral. Now what I wanted to know is that there are some pros and cons of Daikin & Hitachi Model. Like Daikin JTKM series has operating temperature of 46 Degrees only whereas Hitachi is claiming 52 Degree operating Temperature. I found Hitachi has more features than Daikin but less energy efficient. My usage will be around 10-12 hrs and my room size is 14*12. So ya 1.5 Ton is sufficient. Secondly my budget is open so is there better option available if any. I am very confused now so please tell which one I should go for.

Abhishek Jain (Mod)

Hi Varun,

Firstly, I must say that each brand has its own pros and cons and we by no means want to promote Daikin and Hitachi. They just happen to make the most energy efficient ACs. O General has its own positives and their machines are in general quite robust. They are a bit low on efficiency but then that does not take away the durability factor from them. If you want something durable as well as good in efficiency then Mitsubishi Heavy Industries is a good brand. O General is also a premium brand and their only 1.5 ton inverter AC ASGA18JCC is good in terms of efficiency (they have not got it rated on BEE star rating but it would be around 4). But then Daikin JTKM and Hitachi Kashikoi are ACs with highest ISEER of 5.2.

Daikin JTKM is more into air purification technology. Hitachi Kashikoi has more sensors for performance optimization. Daikin JTKM may have low operating temperature while Hitachi Kashikoi will have high operating temperature. I would say Hitachi Kashikoi would be better for you (in Jaipur).

57

Hi Abhishek,
Wow ! Thanku for such a quick and detail response. I always wanted to buy Ogeneral. As you have said it is quite robust and efficient and its only model of inverter split 1.5 ton is the most efficient one. Actually the detail info is not given on there website. So this leads to confusion and force me to see other brands. I am still little bit sceptical about the power consumption of Ogeneral inverter split. Secondly yesterday I have checked about Hitachi model which you have suggested me but it is out of stock in many places in Jaipur. Today again I will check it. Can I go now for Ogeneral Inverter 1.5 ton ?? Once again need your valuable suggestion Abhishek

58
Abhishek Jain (Mod)

You can certainly go for OGeneral Inverter AC. It is quite good (especially considering usage at home).

59

Hi Abhishek,
I am staying in Mumbai city. I am planning to buy 1ton split ac with energy efficiency and Eco friendly models . My usage will be around 40hrs in a week. Pls suggest some good models with a budget of max 32k.

60
Abhishek Jain (Mod)

It will be really good if you an go for a 1 ton inverter AC. Whirlpool fantasia 1 ton inverter AC (Flipkart Link: http://fkrt.it/jG!3MTuuuN ) would be really good. There are also lesser known brands:

Mitashi MiSAC10INv20 (Flipkart Link: http://fkrt.it/jGPqtTuuuN )
Sansui SS4C34.WS1-CM (Flipkart Link: http://fkrt.it/jFlUHTuuuN )

Or if you want popular brands then you can get:

Carrier 1 ton 5 star Esko (Flipkart Link: http://fkrt.it/MXzF2!NNNN )
you may also get Voltas and LG models in this budget.

61

As i m interested to purchase a hot and cold ac, so I contacted a local ac technician and he told me not to buy hot and cold ac because its life is short as the load on the compressor is more then the simple cooling ac and also the mechanism which reverse the ac from cooling to heating gets problem soon. So what do you suggest can i have to go for hot and cold ac or i have to take cooling only ac. Other person told me to use oil filled room heater for the heating purpose. I don't know what to do, i m completely confused. Guide me what to do as i don't want to face any problems and i need high energy efficient ac with best performance. Requirement 1.4 to 1.5tom ac

Suggest me which ac i have to buy and why, in detail if possible.

62
Abhishek Jain (Mod)

Hi Harsh,

If your heating requirement is substantial, then hot and cold ac is the best as it is far more energy efficient than a room heater. But usually the Return on Investment of Hot and Cold AC is not justified because room heaters are used only for 2-3 weeks in a year. And they are quite cheap as compared to an AC. And thus unless the AC is used a lot, the ROI is not justified. As for the technology, you see the same in your cars as well. The car AC can heat as well as cool. The technology is not complicated. As for the comment by technician, I would say, hot and cold ACs have not been around for long for people to make a judgement that their life is short due to the mechanism.

I would also say that if you go for hot and cold AC, then you should only go for one with inverter tech as the ones without inverter tech have less efficiency for cooling. You can check Bluestar 5HNHW18PAFU or Daikin FTHP50.

Dear Abhishek,
This is a very helpful article and thread. I am looking to buy five a/c for my new apartment on 1st floor in Hyderabad. The living room balcony (wall coverage 7x7 ft) faces East. and one utility (only door of 3 ft). There is a window facing West but not exposed to sunlight at any time. The room is rectangle of 34x11 and I intend to separate it out with a bookshelf partition to divide the length of the room with one section at 23 ft and the other at 10 ft (one foot thick two sided ceiling to floor bookshelf) and a dividing door. There are 3 bedrooms, one with 15x15 with balcony (wall coverage 7x7 facing South), second with 14x12 and two windows (East facing 5x4 and North facing 5x4), and third bedroom 11x12 with North facing 5x4 window. All balcony and window glasses are tinted. I want to install 1.5 Ton Hitachi KashiKoi 5400i or Kashikoi 200i HP (due to heating feature but not sure of efficiency, the numbers did not look good) for the two larger bedrooms and one 2T same model for the larger section of the living room. Is the 200i HP good since i saw that the energy consumption was high (can be mistaken)? For the smaller bedrooms, I thought to install one 1.5T a/c for 14x12 room with non-inverter 5 star a/c. Then two 1 Ton 3 star for the smaller living room section and the smallest 10x12 room since usage would be light and mostly not at the same time. Would it be enough? For this last arrangement, I also want to check the option of getting a 2Ton multi indoor unit a/c but these don't come with star ratings. Also don't know if the pipes running would reduce the efficiency. Also, what could be the eco-friendly options to reduce the heat coming in the house from the windows and balconies? Are there any recommended materials that I could use to make hangings in the balconies? Also, would installing a laminated wooden floor reduce the ability of the a/c to cool as compared to a vitrified tile floor? What kind of effect does room lighting (and associated heat) have on effectiveness of a/cs? Please do suggest other models also apart from Hitachi that might be easier on the pocket. Thank you and keep up the good work!

64
Abhishek Jain (Mod)

By the way Blue Star P series or D series would be cheaper than Hitachi.

65
Abhishek Jain (Mod)

Hi Hrishikesh,

Here is your calculation:

23x11 Room, tonnage required: 2.2 ton
10x11 Room, tonnage required: 1 ton
15x15 Room, tonnage required: 2 ton
14x12 Room, tonnage required: 1.5 ton
11x12 Room, tonnage required: 1 ton

Now for your questions:

1) Multi split is an expensive option. It works just because it reduces maintenance, but then because they do not sell much, their prices are higher. I would suggest going for individual split ACs.

2) I am wondering if you would really need hot and cold AC in hyderabad because hyderabad does not get too cold to need heating. Or does it? By the way Kashikoi 200i HP does not look good. In fact most hot and cold ACs are not good in terms of efficiency. Blue Star has a model in 1.5 ton (5HNHW18PAFU) which is good. Daikin has FTHP which is good. But then point is, do you really need it? Because Kashikoi 5400i series from Hitachi is their best series. Daikin FTKM is their best. And for Blue Star P Series is their best. If you want hot and cold then Mitsubishi Heavy also has good models (check http://www.iaplgroup.com/split.php ).

3) Wood would be better than tiles for Air Conditioning. Wood has lesser thermal conductivity as compared to tiles. So when you put on your AC the tiles will get cold, but wood will not get that cold. So electricity consumption will be more with tiles.

4) You should not worry too much about lighting. As long as you use normal LED lights or Fluorescent lights, it should not impact ACs much.

5) To reduce heat from windows you can either use double glazed glass or you can use heat resistant films on windows from companies like 3M.

66

Hi Abhishek,
Thank you for such a detailed reply, really appreciate it. The point about wood is excellent, will think of it. Also dropping the heating option since I already have Usha room heater which should suffice for the two weeks of coldest season in Hyderabad (this option was for my old parents). Since the heater is very portable, we can just keep it anywhere and use it.
I have received a quote from Daikin, and will receive another from Bluestar (but they don't have the P smart model available this month, so will have to wait), and ask for the Hitachi quote also. One thing I noted was most OEMs offer 1 yr (unit) + 5 yrs (compressor) warranty. Daikin only offers 1+1 yr warranty and on the other hand, Carrier offers 1+10 yrs warranty. Should i be concerned about this? I had one LG fridge thermostat and one LG microwave convection part going bad one month before warranty and luckily escaped expensive repairs. Should I also consider the Superia inverter ac from Carrier? I see that only Daikin and Carrier use R-32 Given the numbers in your article, isn't R-410 much worse than R-32?

67
Abhishek Jain (Mod)

R32 and R410A are both HFCs. R32 is slightly better. But then I would not say that R410 is worse compared to R32. Using "worse" word for it would be harsh, because the difference is minor.

You can go for carrier superia as well because that is also a good AC. However, in terms of efficiency the models I mentioned are better. Also inverter compressor usually should easily go on without problems for 10 years. But still if that gives you peace of mind, then you must go with a brand that gives you better warranty. Usually condenser is the one that gives problems. Compressor usually does not give problems. You can go with Carrier Superia.

68

Ok great, thanks a ton, no pun intended :) I was a bit miffed with the 3x global warming potential difference between R410A and R32 (though R410A seems to have more GWP than even R22). Coming to warranty - considering that compressors would be fine, I need to cover for the condensers and PCBs. For warranty, one dealer just told me that Loyd's gives 5 years warranty for both unit and compressor. The prices also seem slightly lower than Daikin, Hitachi, and Bluestar (only comparing 3 star inverters since Lloyd has no higher rated ac). Now I am battling the comfort of a full 5 year warranty (Lloyd) against a one year warranty (others) and ISEER of only 3.8 (Lloyd) against availability of ISEER performance of 5+ (others with 5 star inverter). My experience is that once the initial purchase cost is done with, we forget it as long as the device works satisfactorily. Only when the appliance has issues, we lament all the money spent in purchase and the inconvenience + repairs. The dealer also said that mostly condensers and PCBs have issues. By the way, Bluestar did not turn out much cheaper compared to Daikin and Hitachi (all top line models only); I'll confirm this when I get another quote for Bluestar. I am also thinking to go only for 3 ACs and not 5 since a good desert cooler is a much healthier+cheaper option for the hottest two months of summer.

69
Abhishek Jain (Mod)

Warranty is like insurance. If you happen to need it, you love it, else you would feel that you should have gone with a better brand. It truly depends on what kind of comfort does a warranty provide you. It varies from individual to individual. It is not that top brand guarantees break free operation. But certainty is more. But if you buy an expensive product and it fails then you would lament not going for a brand that gives longer warranty. There is no clear cut answer for the right model to choose. Also do check the things that are covered in warranty and make sure that condenser and PCB are covered.

Which refrigerator consumes more power 1 Double door convertible or 2 Single door

71
Abhishek Jain (Mod)

What sized refrigerator are you comparing? Because electricity consumption also depends on size of refrigerator.

72

Hi,
I need to buy 2, 1.5 ton inverter ac, my budget is open and i want the most efficient, as I use ac for about 20 hrs a day. I have zeroed in on JTKM50 Daikin and Mitsubishi electrical msy-gn. both 5 star which should I buy

73
Abhishek Jain (Mod)

Your usage is really high and going for the most efficient one would be better. So Daikin JTKM50 or HItachi Kashikoi 5400i.

74

Daikin jtkm50 or hitachi 5400i in my usage. Thanks a ton

75
Abhishek Jain (Mod)

Any one of them. Both have similar energy efficiency. Hitachi has sensors for optimization of electricity while Daikin has air purifier. If the room will remain closed for 20 hours, then air purification would be needed.

76

is there any major difference in power consumption between 3star and 5star rating ACs

77
Abhishek Jain (Mod)

There certainly is. ROI depends on your use of AC and electricity tariff.

78

Is T-3 compressor is better than conventional compressor

79
Abhishek Jain (Mod)

Which model of AC did you find with T3 compressor?

80

Which gas is having better cooling capacity. R32/R22 or R410a

81
Abhishek Jain (Mod)

Cooling capacity does not depend on refrigerant.

82

Great effort abhishesh,
I am looking for 1.5 to Split which will be good in gas rating ,like not harmful and and price would be approx 32k .and would be good in cooling in delhi .would also consume less electricity . which will be better in between Daikin ,Bluestar or carrier and please mention model number also.
Another window i am looking to buy for 1.5 ton .carrier or hitach which is better and please mention model number
thax

83
Abhishek Jain (Mod)

Hi Ganeev,

Daikin, Bluestar and Carrier are premium brands. Ususally their 5 star non inverter ACs would cost about 40-45K. Even their BEE 3 star models (that are not very electricity saving) of 1.5 ton mostly cost more than 32K. Extremely difficult to find something in your brand preference and budget. The best electricity saving models that you can get in your budget are 1.5 ton inverter ACs from Huyndai, Mitashi or Sansui:

Hyundai HS4I54.GCO-CM (Flipkart Link: http://fkrt.it/2wmwN!NNNN )
Mitashi MiSAC15INv20 (Flipkart Link: http://fkrt.it/2wV3C!NNNN )
Sansui SS4C54.WS1-CM (Flipkart LInk: http://fkrt.it/LB3MFTuuuN )

Or you may even look at these:

LG JS-Q18CPXD (Amazon Link: http://amzn.to/2rZ5jFv )
LG JS-Q18AFXD (Amazon Link: http://amzn.to/2rYFHso )
LG JS-Q18ATXD (Amazon Link: http://amzn.to/2s76PGH )

In window AC models you can look at these models from Hitachi:

Hitachi RAV518HUD (Amazon Link: http://amzn.to/2negUKO , Flipkart Link: http://fkrt.it/AF7GETuuuN )

or

Hitachi RAT518HUD (Amazon Link: http://amzn.to/2mMYF3P , Flipkart Link: http://fkrt.it/AFS7ETuuuN )

84

Which gas was best. R32 OR R410A.

85
Abhishek Jain (Mod)

R32 is better.

86
vaibhav prajapati

sir i want to buy 1.5 ton window ac which brand will be good
Hitachi or carrier

87
Abhishek Jain (Mod)

Hitachi has better window AC models.

88

i want a window ac 1.5 ton with refrigent r-32 or r 410

89
Abhishek Jain (Mod)

There are no window ACs with R-32 refrigerant. There are very few with R-410A. However, the models are not very energy efficient. The best one is Hitachi RAW318KXDAI (Kaze Plus Eco) with BEE 3 star rating (equivalent to BEE 2 star rating in split ACs). O General AXGT18FHTA is a BEE 2 star rated one (equivalent to BEE 1 star rating in split ACs).

90

HI Abhishek,

why you have not suggested videocon AC's whether it is good product or not??

91
Abhishek Jain (Mod)

Every brand available in market that does some amount of sales works. Videocon does sell decently in market. So I cannot say that it is bad. It certainly work and if you want you can certainly go ahead and buy it. It is all about comparison and opinions. If you ask which is better Daikin or Videocon, I can give an answer. But then I cannot say Videocon is bad. It works and that is why people buy it.

Most of our recommendations are based on 1) Efficiency 2) Quality (compared value) and 3) Consumer demand and budget. Videocon certainly does not rank high in efficiency standards within each star rating. Quality wise there are better brands and thus it does not usually come in our recommendations. If you just expect a "good" or "bad" answer from me, then I would say it is a good brand. Their ACs certainly work decently.

92

Hello Abhishek, I am planning to buy a new split AC, 1.5 Ton, inverter, around the range of 35k. Which AC would you suggest? I have tried to zero-in on 1) LG Dual inverter JS18NXPA, Lloyd LS18VI, Videocon inverter AC, Godrej inverter AC 5 star (claiming 980 units). Which one is better option or if you can suggest a better option in similar range.Thanks.

93
Abhishek Jain (Mod)

Hi Joginder,

LG inverter models would be the best in your range. You can check these:

LG JS-Q18ATXD (Amazon Link: http://amzn.to/2plxzkK )

LG JS-Q18AFXD (Amazon Link: http://amzn.to/2oA2VBg ) similar model with different design

LG JS-Q18CPXD (Amazon Link: http://amzn.to/2oA7Ban ) ... this is an Amazon only product and I doubt you will get this in market.

LG JS-Q18NPXA (Amazon Link: http://amzn.to/2oA6Nm5 )

LG JS-Q18SUXD (Amazon Link: http://amzn.to/2oMG2Le )

LG JS-Q18AUXA (Amazon Link: http://amzn.to/2oMjWqB )

94

Thank you Abhishek, would go for JS-Q18NPXA as I may get it around 33-34k in market. Thanks again.

95

hello mr. abhishek
i have 1.5 ton dual inverter ac lg make.if room temp.is 35 degree then this ac taking 2 hrs for maintain 25 degree.is this right or wrong.......
.my room size is 10*11.

96
Abhishek Jain (Mod)

It should cool the room faster. The room is small and the AC is big, so it should be much faster.

97

Sir / Madam,

now i am using Samsung AR12HV5NBWK Invertor AC 1 ton. now gas was leaked please advice which was filled earlier?

rajesh.

98
Abhishek Jain (Mod)

From what I know, it uses R410A. But please confirm this with Samsung as well.

99

hi,, i have the godrej split ac that uses R290, i was told that R290 can not be topped up, the old gas is released and new gas is filled up in the ac is that true

100
Abhishek Jain (Mod)

Hi Jesse,

I am not 100% sure about it, but I feel that one should be able to to up R290. I do not see a reason why it has to be refilled.

101

Hi.. Mr Jain
Thanks for your quick response for my Query,,, so i may try and get it topped up when the time comes,, and of course hope for the best :)

102

If AC running in R-22 gas is banned by govt.
Then can the same AC run on other gas certified by govt.

103
Abhishek Jain (Mod)

It depends on system design. Cannot say which refrigerant can work.

104

Can u suggest me names of Ac containing R-290 and R-600 A gas. ?

105
Abhishek Jain (Mod)

ACs do not use R-600A. Godrej is the only brand that uses R-290 and their NXW series has R-290.

106

R-22 gas , Is it Green gas ?
Has govt. of india certified it.

107
Abhishek Jain (Mod)

It is not a green Gas. It is HCFC. Govt of India has a plan to phase it out completely.

You can look at the top air conditioners on this link: https://www.bijlibachao.com/top-ten-appliances/best-air-conditioner-ac-window-split-hitachi-lg-carrier-samsung-electricity-consumption-tonnage-in-india.html

Daikin JTKM50
Hitachi Kashikoi 5400i
Blue Star 5CNHW18PAFU (Amazon Link: http://amzn.to/2qsd2e7 ) are all copper and highly energy efficient. They have eco friendly gas as well. We do not have data on size to suggest you compact sized ones.

Hi,
I am planning to buy 1.5 Ton inverter AC from Electrolux . Is it a good choice.

111
Abhishek Jain (Mod)

Hi Vikram,

Electrolux is one brand which does not get too much attention but is decently good. Quite value for money brand. Their BEE 3 star 1.5 ton inverter AC has ISEER of 3.73 which is decently good. The 5 star model has ISEER of 4.59 which is quite good. You can certainly go for Electrolux inverter AC.

112

Hi, Thanks a lot for the information. its 3 star model no ES18Q41 , Could you please inform me what would be power consumption in full load and half load mode of compressor of the same . This model is not available on their website.

113
Abhishek Jain (Mod)

Hi Vikram,

Unfortunately I also do not have too much information. The data from BEE shows that it has ISEER of 3.73 and Annual Electricity Consumption (for 1600 hrs) is 1098 units. They have registered this model with BEE.

114
Abhishek Mishra

hello Abhishek, i am planning to buy a 1.5 ton ac. I am looking for LG brand (model- JS-Q18ATXD). Is it a right choice ? Or should I go for any other brand
I have chosen this ac because it has many good features and a good brand as well.
please suggest me the best i can get in arround 40k.

115
Abhishek Jain (Mod)

Hi Abhishek,

LG Dual Inverter models are quite good and feature rich. The best being ability to work between 90V-450V. I think it is a good choice and you can go for it.

116
Abhishek Mishra

Do it has corrosion protection or not (LG JS-Q18ATXD) ?

117
Abhishek Jain (Mod)

It does have corrosion protection. All LG models have corrosion protection. But this model has aluminium alloy condenser.

119
Abhishek Jain (Mod)

ac का tonnage city पर निर्भर करता है| दिल्ली में जहाँ गर्मी ज़्यादा होती है वहां बड़ा AC लगता है और मुंबई में जहाँ कम गर्मी पड़ती है वहां उतने ही बड़े कमरे में छोटा AC भी चल जाता है| AC का सही tonnage जानने के लिए इस page पर दिए calculator का इस्तेमाल करें: https://www.bijlibachao.com/top-ten-appliances/best-air-conditioner-ac-window-split-hitachi-lg-carrier-samsung-electricity-consumption-tonnage-in-india.html

मेरे ख्याल से आपको 2 ton का AC लगेगा और आप यह AC देख सकते हैं:

MITSUBISHI ELECTRIC MSY-GK24VA
HITACHI RMC424EAEA
HITACHI RMB324IAEA
BLUESTAR 3CNHW24TAFU

120

If I have a R410A inverter Ac can i refill it with R290 or only R410A will work?

121
Abhishek Jain (Mod)

Both need different size of tubing for condenser. Most brands are currently not using R290 because copper tubing to make condenser for the same is not available in Indian market. Godrej also uses Aluminium for R290. It will not be an easy refill.

122

With Bluestar 5CNHW18PAFU what options do I have if and when I go for a refill?

123
Abhishek Jain (Mod)

Refill is required only when there is a gas leak. If the gas does not leak, no refill is required. And this model has strong corrosion protection, so gas should not leak soon (or should never leak). You will have to refill it with R410A if gas leaks.

124

thanks for this info. I used to think that the gas is used like petrol and is depleted and therefore it requires a refill after few years.

125
Abhishek Jain (Mod)

It is not like that. Gas once filled if it does not leak then it can last for full life of the AC.

Actually, I have purchased an a/c with r-22 refrigerant but now it seems that it isn't Eco- friendly.The above the information is really good and very knowledgefull.
Thanks

129

Anyone please suggest me which one is good out of these Daikin series of ACs - ATF, DTF, or FTF.
I would like to buy 1.5 Ton 5 star AC with cooling mode only. I prefer to buy an environmental friendly AC despite of cost. In fact, I prefer O General, but it is still using the R410A, which is not an environmental friendly. Please suggest me one.

130
Abhishek Jain (Mod)

ATF, DTF and FTF are the same series with similar technical specification but different features. ATF and DTF are smart phone operable and have different air filters. FTF is basic model. You can go for any one of them depending on your budget.

131

Hi Abhishek, my bedroom is 220 sq ft and in summer the temperatures goes to 42-44 degree and in winter goes to 4-6 degree. Suggest me inverter AC with good energy rating as well as features of auto cleaning, auto off timer, copper condenser. I am looking in brand Voltas, Bluestar, Carrier and Hitachi. The max usage in summer will be 3-4 months. Also can the same be used for heating in winter?

132
Abhishek Jain (Mod)

Hello Mr Brij,

To calculate right tonnage, one needs to evaluate multiple factors. And without knowing them I cannot suggest you the right product. And calculating right tonnage is the most important thing to do before buying an AC. I would suggest that you use the calculator on this page to calculate the right tonnage: https://www.bijlibachao.com/top-ten-appliances/best-air-conditioner-ac-window-split-hitachi-lg-carrier-samsung-electricity-consumption-tonnage-in-india.html

One you have calculate the tonnage, let me know the same along with the budget that you have and I can suggest you some good models. As for heating feature, I would say Voltas has non inverter heating and cooling models, which are not very energy efficient. Hitachi does not have heating models. Blue Star has the best heating and cooling inverter ACs, but I will have to look at your tonnage and budget to say if it will fit in your requirements or not.

Lloyd is a good brand. If your usage is not high then this seems like a good choice.

135

Hi Abhishek,

I am in dilemma in buying the perfect AC for my bedroom. The room size is 16.5x11.7x10 feet. I want to buy an AC with heating and cooling facility as well as saving electricity and the atmosphere too.

Can you please suggest one for me?

136
Abhishek Jain (Mod)

Go for Blue Star 5HNHW18PAFU or Daikin FTHP50.

137

Hi Abhishek,
Will 1.5 Tonnage be sufficient for the room size?

139
Abhishek Jain (Mod)

Depends on the peak summer temperatures in your city. But most likely yes. Which city are you in?

140

Hi Abhishek,

Sorry for the late reply. I am from Kolkata, the city with scorching heat and horrifying humidity. I went to check on the Inverter ACs and the salesperson asked about the size of the room where the AC will work on. He told me to go for a 2 ton (at least a 1.8 ton) AC.

141
Abhishek Jain (Mod)

Hi Jayanta,

2 ton or 1.8 ton is the right calculation for your room. And frankly in Kolkata you do not need hot and cold AC. We usually suggest people to go for hot and cold only if the heating feature will be used for at least couple of month. Or when you use it to replace a room heater which is used for 2 months. There is no place in India where that happens. Even in North India room heater are used only for couple of weeks in a year. It will be better if you go for a cooling only inverter AC.

If you want heating and cooling one then you can look at Blue Star 5HNHW24PAFU (5 star) or Daikin FTHP60SRV16 (4 star) or Blue Star HNHW24CBFU (3 star) or Carrier Superia 365 inverter 2 ton

Hi Abhishek,

Thank you for the details. Please suggest me 2 Ton Inverter AC with 5 star rating (preferably with refrigerant R290).

You can look at these:

Mitsubishi Electric MSY-GK24VA
Blue Star 5CNHW24PAFU (Amazon Link: http://amzn.to/2n5WXZR )
Daikin JTKM60
Toshiba RAS-22N3KCV-IN + RAS-22N3ACV-IN
Blue Star 5CNHW24DAFU

Godrej is the only brand that uses R290 and they do not have a 2 ton inverter AC.
