Electricity Saving Tips For Homes And Offices

Refrigerators with Inverter technology can help save electricity

By on April 22, 2016

Are you planning to buy a refrigerator and looking for energy saving options? If upfront cost for buying is not a concern for you then do look at refrigerators with inverter technology. Rest assured that the extra money you pay upfront will be recovered in the form of electricity savings. Inverter technology that was developed in Japan is the most efficient refrigeration technology available in the market today that can save up to 30-50% electricity consumed (units consumed) compared to regular refrigerators available.

How does a refrigerator work?

Whenever it is hot and we want to feel cooler, if we take a bath, we suddenly start feeling better. The moisture (or water) on our body evaporates by taking heat from our body and makes us feel cooler. Similarly in a refrigerator there is a refrigerant called HFC (Hydro Floro Carbon) that moves in the pipes or coils on the rear part of the refrigerator. When it is in a liquid form, it takes the heat from the refrigerator contents and evaporates to form gas there by cooling the things kept in the refrigerator. The gas is then compressed using a compressor to convert it into liquid again, and the cycle continues. The compressor uses electricity to do its job and is the most electricity consuming part of a refrigerator.

Refrigerator also has a device called “Thermocouple” which senses the temperature inside the refrigerator and makes the compressor go “on” or “off”. The thermocouple works as per the temperature set in the refrigerator (yes you can set temperature in a refrigerator as well and we will explain it more in our other articles on refrigerators).

How does a compressor in regular refrigerator work?

Most compressors in regular refrigerators are single speed refrigerators. They are either “on” or “off” based on the temperature in the refrigerator and the setting in the thermocouple. Most compressors are designed to handle peak load conditions (for high temperatures in summers), which means that they run at peak load even in winters when the cooling requirement is less. Every time the refrigerator door is opened, heat enters the refrigerator and the compressor has to take care of this load as well. So most regular compressors are built to take care of peak load plus the “door open shut” load which during most of the year is much more than the actual requirement.

How does a compressor with inverter technology work?

A compressor with inverter technology works very much like a car accelerator. When the speed required is more, the acceleration is more, and when it is less, and then the acceleration is less. This makes sure that during summer months when cooling load is more, the compressor works at peak capacity taking more electricity. But during winter months when cooling load is less, the compressor works less there by consuming less electricity. Even in summer month, the night temperature is less than the day temperature and thus electricity savings happen in night when compressor can run at a lesser speed.

This kind of compressor never switches off even when the temperature stabilizes, but runs at a slower speed maintaining the temperature inside the refrigerator. The benefits are:

  • In an “on” “off” cycle of a regular refrigerator, inside temperature varies throughout. But in case of inverter technology, temperature is more stable.
  • The amount of noise made by the refrigerator is much less in refrigerators with inverter technology as compared to the regular ones.
  • Energy or electricity consumption is much less when the temperature stabilizes.


Although prices of inverter technology refrigerators are on a higher side, but they can save a good amount of electricity, there by helping you recover the money in your electricity bills.


Lesser known benefits of Inverter Technology

  • Regular motors need 3-4 times more current (more than running current) at startup. So the inverter/generator size needed to run any AC or Refrigerator increases significantly. But Inverter Technology air conditioners and refrigerators have variable speed motors that start up gradually needing much lesser current at startup. Thus the size of inverter/generator required to startup is less. For e.g. A 1.5 ton fixed speed AC that runs at about 10 Amp current may need up to 30 Amp current at startup and thus a 5 kVA inverter/generator. But an inverter technology Air Conditioner needs about 6-7 Amp current and not much more at startup and thus a 1.5 kVA or 2 kVA inverter/generator is good enough to support it.
  • Regular motors have much lower power factor. In commercial and industrial connections there is penalty for low power factor and rebates for higher power factor. An inverter technology motor will have power factor close to unity (or 1) which not only results in lesser electricity consumption but also help get rebates on better power factor.
  • If you are planning to use Solar PV for air conditioner, then it is the best to use inverter technology air conditioner or refrigerator as it not only reduces the size of PV panels because it consumes lesser electricity, it also reduces the size of inverter to be put along with the PV panel.

Hi Abhishek,
We have bought a LG Refrigerator in the year 2002 and it has functioned so far for the past 15 yrs without any issues. Recently the cooling was fluctuating resulting in Over Cold or Less Cold and after diagnosing, it happened to be a faulty timer. The Service person told that it would cost INR 1500 to replace the timer. Kindly suggest if it would be wise to replace the timer and continue using the same fridge.

Abhishek Jain (Mod)

Your old refrigerator would be consuming about 3-4 units a day (depending on the size). It can come down to 0.5-1 unit per day (again depending on size). You could save 2-3 unit per day by changing to a new one. That means in a month that would be 60-90 units per month. At about Rs 7 a unit (you will have to check your own electricity costs, this is national average), it would be Rs 420-630 or roughly Rs 500 per month. In a year that comes to Rs 6000. Again depending on size it would be about Rs 20000-30000 (or more if it is huge). So the payback will happen in about 4-5 years. I hope this helps you in making a decision.


Namaste Abhsihek,

First things first, Thank you for such a wonderful and informative site. It helps one and all in understanding the new technologies. Appreciate your work and dedication on this and educating people. Salutes to you.

1) We have a Whirlpool double door 220 ltrs (model : WRN A 228 G 20, year 2001) and its now not working for first time since the date of purchase. It has given a good service of 16 yrs till date without any problems, no repairs. Company technical person said compressor has to be replaced along with the gas and it costs about 7k to 8k. So we are checking whether to go for new one or get this repaired? Can you please suggest us on this?

Do we need to for a good inverter technology based refrigerator. I have read in this site about it and really impressed.
Does Godrej has inverter technology based refrigerator between 200 and 300 ltrs. Which other companies have this?

2) How about the after sales service of these companies?

3) Does inverter tech based refrigerators also have the BEE rating like 3/4/5 stars? If yes then can you please let me know the exact technical and other differences between a normal 5 star based and a inverted based 3/4/5 star refrigerator.


Abhishek Jain (Mod)

Hi Santosh,

Here is my response:

1) It will be better to go for a new refrigerator because energy efficiencies of refrigerators have improved significantly since 2001. Also godrej does not have inverter technology based refrigerators. Mostly LG, Samsung, Hitachi, Panasonic have inverter technology refrigerators.

2) LG and Samsung are the most popular brands in Refrigerators. Their service network is huge.

3) Inverter Tech refrigerators do have BEE 3/4/5 star ratings. Energy consumption wise even a normal refrigerator can be BEE 5 star. But inverter tech refrigerator is better in consistently maintaining the temperature inside the refrigerator, which is better for keeping food fresh for a longer duration. The main technical difference is in the compressor.


Hi Abhishek,

Thanks for the prompt response.

Could you please let me know few models of LG and Samsung refrigerators with inverter based tech so that i can also go through the details and purchase it.


Abhishek Jain (Mod)

Hi Santosh,

You can look at any of these:

BrandModelAmazon LinkFlipkart Link
LGGL-I302RTNL http://fkrt.it/yweqT!NNNN
LGGL-Q282STNL http://fkrt.it/AB5jjTuuuN
LGGL-U302JSOL http://fkrt.it/AVsJBTuuuN

My house is located near a drain (nullah). I have a 6 year old Toshiba refrigerator and gas from the copper coils leaked couple of times. The person who repaired the refrigerator informed me that the reason for leakage of gas was (i) staying nearby a nullah and (ii) copper used by the manufacturer (Toshiba) is very thin and of cheaper quality. Copper coils had to be replaced twice during this period. Kindly suggest a refrigerator (brand name) with model no. having (a) tough copper coils and (ii) withstand corrosion due to nullah.

With regards,

Abhishek Jain (Mod)

This is interesting because I have heard of gas leakages due to corrosion in ACs quite a lot, but this usually does not happen in refrigerators. This is due to couple of reasons 1) AC outdoor units are outside but refrigerators are usually inside 2) Most of the refrigerators these days have coils inside the refrigerator body and are usually not exposed outside. Does the refrigerator that you have has coils outside and exposed? Usually coils are pretty standard and based on the type of refrigerant being used. In ACs manufacturers apply corrosion protection and mention the same on their specifications. But usually such information is not available for refrigerators.

What size refrigerator are you looking at? Also what is your budget?


How are the Bosch Refrigerators? They do not mention about Inverter technology in their product description.
However for their 288 lt model, energy consumption shown on the label is similar or even less than some of the inverter technology models from Samsung or LG of same capacity. The inner space of Bosch refrigerator is better compared to other brands. However I agree that cost is more. If you keep aside the cost, buying bosch is recommended? pls suggest


Abhishek Jain (Mod)

Hi Sandeep,

Energy consumption depends on several factors along with Inverter technology compressor. The whole design has to be better. And that is what comes out in total electricity consumption. You will find that most 5 and 4 star models are inverter technology (in frost free). But then there are non inverter ones as well in 4 star. And then you will find a good mix of inverter and non inverter in BEE 3 star.

Let me tell you, if a manufacturer adds a good refrigerant, the efficiency improves (inverter or non inverter). Add a few good sensors to optimize temperature and electricity, your efficiency improves. Compressor is one such factor and definitely an important one. As you will find the most efficient models in the market having inverter compressor.

Having said that, Bosch is a great german brand with solid technology. But their best models are at best BEE 3 star rated. But then 3 star rating is not bad in refrigerators (considering the costs of electricity in India currently). You will hardly find a few BEE 5 star rated models because the cost benefit becomes difficult for them unless the tariff is really high (like in Mumbai). So certainly Bosch is recommended, but please make sure that you go for a model with BEE 3 star rating at least.


Please suggest me any fridge with frost free feature for, around 25,000rs.

Dear Abhishek:

I need to replace my LG 250 Ltrs refrigerator model. It is old and its compressor is ALWAYS on. The fridge does not get much use - door opening and closing. I am looking to get an energy efficient, inexpensive refrigerator. You have written a great article on inverter tech, thank you. Are there any models that you would recommend for me? Thank you for your great work.

Abhishek Jain (Mod)

Hi Rahul,

What is the size that you are looking at and what is your budget for this refrigerator?


Dear Abhishek,
Recently one of my referigerator 495 ltrs, double door LG with compressor invertor technology went dead.After getting it replaced by company's engineer i have a doubt that the gas has not been fully pumped in.How much gas is required in the above mentioned invertor compressor ??

Abhishek Jain (Mod)

Hi Amit,

It is not the weight which is important. It is the right pressure that is required. As per this chart: http://www.oz-chill.com/wp-content/uploads/2013/08/Pressure_Temp-Chart-OZ-600a.pdf

at around 48 degrees 94.54 psi is required.


is that mean LG has better technology then Whirlpool?

Abhishek Jain (Mod)

LG uses inverter technology which is quite good. But Whirlpool uses 6th sense (sensor) technology which is also quite good. Every brand has its strengths.


Please suggest the best one....
LG - 230 Ltrs - Power conusmption 169 Units per annum with inverter technology - cost 22190/-
Whirlpool - 215 Ltrs - Power consumption 171 Unites per annum without Invertor technoloy - Cost 17600/-

Abhishek Jain (Mod)

The electricity consumption difference is not much. You may go for whirlpool if you are concerned about costs. You may go for LG if you want better technology and are ready to spend more.


I would like to buy a refrigerator - Single door approx. 230 liters


Hi Abhisekh
This is Ajay from Hyderabd


Hi Abhisekh......can tell me some LG evercool single door 190 ltrs (₹13k-₹16k) models with low electric consumption (in term of units per year) . And also abt cooling pad technology of Whirlpool and Godrej ...which of the three is a better choice if we take electric consumption into account?

Abhishek Jain (Mod)

Hi Lata,

In LG you will get BEE 4 star rated models with this feature. You can look at these:

LG GL-B201AGHP (Amazon Link: http://amzn.to/2plhxEB , Flipkart Link: http://fkrt.it/uezJ4!NNNN )
LG GL-B201AMHP (Amazon Link: http://amzn.to/2oAUUhl )
LG GL-B201ASHP (Amazon Link: http://amzn.to/2owUMxr , Flipkart Link: http://fkrt.it/N5b~yTuuuN )

LG's power cut evercool can last for 9 hours. Whirlpool claims to last for 12 hours. Godrej Stay Cool Technology is only for freezer and not for the whole fridge. From electricity consumption point of view, I think this model from Whirlpool would be really good:

Whirlpool 215 IMFRESH PRM 5S REGALIA (Amazon Link: http://amzn.to/2phonhb , Flipkart Link: http://fkrt.it/Nh3ipTuuuN )

Hi Abhishek. I wanna buy a single door-direct cool refrigerator(2017) between 150/170/180/188/190/192 ltr. My budget is between Rs 9ooo/- to 15000/-.
Can you help me out this following information in this capacity of liter & budget from those models you will suggest for me -

1. Bee star rating 3/4/5 2. How many hours cooling retention during power cuts as per models ? 3. how much Yearly electric consumption units as per 2017 models with & without inverter system. 4. Is their available Inverter technology with long cooling retention during power cuts in my budget ? if yes then how many hour according to models ? 5. Voltage fluctuation ratio with inverter or without inverter as per models.

Can you inform me that how much electric consumption units as per year count according liter capacity with & without inverter technology in star rating 3/4/5 according 2017 rating in general.

How is the customer review on this model - 205 ICEMAGIC POWERCOOL PRM 3S wine Fiesta 190ltr (2017) & is this models available in real market with 5 star or 4 star ratting also?

In generally Is their create any cooling retention differences between with & without inverter system ?

Kindly help me out :)

Abhishek Jain (Mod)

Hi Sdip,

Here are a few models:

BEE 5 star:
Electrolux EN205 (Flipkart Link: http://fkrt.it/5zAUlTuuuN )

BEE 4 star:
Haier HRD-1954BS-R (Flipkart Link: http://fkrt.it/5zapNTuuuN )
Haier HRD-1954CBD-R (Flipkart Link: http://fkrt.it/5PKnsTuuuN )
Haier HRD-1954CRD-R (Flipkart Link: http://fkrt.it/eieqH!NNNN )

in BEE 3 star (with inverter technology compressor):

Samsung RR20M111ZSE/HL (Flipkart Link: http://fkrt.it/54bh2TuuuN )
LG GL-B201AHAW (Flipkart Link: http://fkrt.it/5P8J7TuuuN )
LG GL-B201ASAW (Flipkart Link: http://fkrt.it/eyCXI!NNNN )

2) Cooling retention is not there in every model. Usually it is between 7 to 10 hrs if a refrigerator has cooling pad.

3) The BEE 5 star rated model mentioned above has annual electricity consumption of 136 units. BEE 4 star rated ones have 151 units and BEE 3 star rated ones have 197 units. Interestingly most models with inverter are BEE 3 star rated (this is because efficiency is not only driven by compressor, but also with design of condenser, evaporator and refrigerant).

4) Inverter technology is there only in LG and Samsung and I could not find a model which has both cooling pad and inverter technology.

5) Most refrigerators these days have long operating voltage range. They can work easily between 110V and 290V. You will see built in stabilizer mentioned in almost all refrigerators. So inverter and non inverter does not matter in this.

There is less feedback available for 205 ICEMAGIC POWERCOOL PRM 3S wine Fiesta 190ltr (2017) but in general it is good. It is a BEE 3 star rated model, so should not be sold with 5 or 4 star rating.

Inverter can maintain consistency in cooling (maintaining temperature) but cooling retention depends on cool pad.


Hi Abhishek.I am thinking to buy LG GL-B201ASAW.Is this model good.Does this model has inverter technology.Amazon states this model has inverter technology. But Flipkart states in its specifications copmpressor is reciprocatory.Please clarify to me.

Abhishek Jain (Mod)

This model does have inverter compressor. And invertor compressor can be a reciprocatory compressor. Reciprocatory is a way in which piston moves and inverter is a way in which electric current is controlled for the compressor. Two different things that can coexist.


Hi Abhishek. This is an extremely helpful site. I habve learned a lot regarding the latest technology in refrigerator (for e.g. invertor technology). I am using Whirlpool Double-door freeze for the last 10 years, and are very satisfied with the product. Hence, I am looking for a new refrigerator from whirlpool brand. However, after learning about invertor technology, I am thinking of purchasing RT28M3022 (253litres). Is this model good, or I should go for some other model of Samsung? How is the customer review of Samsung refrigerator?

Abhishek Jain (Mod)

Hi Saurabh,

Whirlpool, LG and Samsung are market leaders in Refrigerators. They have the biggest market share. If they were bad, they would not have been leaders.

The model you are looking at is a BEE 2 star rated refrigerator. I would suggest going for at least BEE 3 star rated refrigerator. You can look at these models:

Samsung RT28K3023SE/HL

Samsung RT28K3043S8/HL (Amazon Link: http://amzn.to/2orqdv1 , Flipkart Link: http://fkrt.it/bGJaF!NNNN )

Samsung RT28K3043S8/NL (Amazon Link: http://amzn.to/2orpR7v , Flipkart Link: http://fkrt.it/bGWqD!NNNN )

Having said that, I would also say that Whirlpool is also not bad. If you want to go for whirlpool, you can also look at BEE 3 star rated models from whirlpool:

Whirlpool NEO DF258 ROY 3S (Amazon Link: http://amzn.to/2oriUDw , Flipkart Link: http://fkrt.it/bFSfA!NNNN )

Whirlpool NEO IF258 ELT 3S (Flipkart Link: http://fkrt.it/sX16!TuuuN )

Whirlpool would be a bit cheaper than Samsung. All these models would have similar star rating and almost similar electricity consumption. But Samsung has inverter technology, which is in general better.


any single door inverter technology fridge available in India?

Abhishek Jain (Mod)

There are many in LG and Samsung. What size (in lts) are you looking for?

Abhishek Jain (Mod)

The inverter technology single door models start from 190 lts. You can look at these:

Samsung RR20K282ZR2 or RR20K282ZU2


LG GL-B201ASDX (Amazon Link: http://amzn.to/2ndKReP )


this LG one has 4 start rating only

Abhishek Jain (Mod)

LG does not have a model that has inverter technology compressor and 5 star rating.


ok Is 4 start + invertor tech Fridge better than 5 start BEE rating?

Abhishek Jain (Mod)

Not really. It depends. The electricity consumption of refrigerators mentioned on BEE label is in ideal conditions. But in real it is not always ideal. Inverter compressor runs at better efficiency when the load is less and the efficiency is not good when load is more than the rated load. So if you overload your refrigerator, then inverter tech will not be efficient. But if your refrigerator mostly stays clean and less loaded, then it may work better than a fridge with 5 star rating.

It would be safer to go for a fridge with BEE 5 star rating.


kindly suggest few models of Samsung with capacity >250L and double door with 2017 model and 4 star rating with inverter technology

Abhishek Jain (Mod)

You can look at these models:

Samsung RT30M3425S8/HL (BEE 5 star rated) (Flipkart Link: http://fkrt.it/tEXT7!NNNN , Amazon Link: http://amzn.to/2o1sH3K )

Samsung RT30K37547E/HL (BEE 4 star rated) (Flipkart Link: http://fkrt.it/tEjHQ!NNNN , Amazon Link: http://amzn.to/2o1uiGw )


Hi Abhishek,

I want to buy a single door refrigerator. As in the market , a new technology based refrigerators are availble, say smart inverter technology( only with Samsung & LG). so got little bit confused to go with that kind of refrigerators or normal compressor ones. And does it mean that smart inverter technology refrigerators doesn't require separate stabilzer to be used whereas other refrigerator which says though it has stabilizer free opeartion, do we need to use separate stabilizer to avoid any interuption. Please guide me so that I can wave off my doubts and can go for the refrigerator of my choice. And also please suggest some of the single door model budget within 20000 with inverter technology.



Hi Abhishek,

Awaiting for your response to the query. Thanks a lot.

Abhishek Jain (Mod)

I guess you did not see the reply below. I replied to you 2 hours back! Copying again:

Hi Sucharita,

Inverter Technology is certainly better than
normal compressors, and we have listed a whole lot of benefits on this
page. It is good not only for electricity consumption but also for
keeping a consistent temperature in the refrigerator for keeping food

Stabilizers are not needed for most modern refrigerators
(be it inverter or non inverter), unless manufacturer specifies to use a
stabilizer. Inverter technology compressor does not need a stabilizer
at all.

You can look at these refrigerators:

Samsung RR22M242YSE/NL (Amazon Link: http://amzn.to/2nqwKE4 , Flipkart Link: http://fkrt.it/twnZs!NNNN )

Samsung RR22M274YU2/NL (Amazon Link: http://amzn.to/2nH7dbK , Flipkart Link: http://fkrt.it/g5lF3TuuuN )

Hello Abhishek,

I am planning to buy a refrigerator about 220 to 250 liters but we are confused that should go for single door or double door our preference is that it should be energy saving with inverter technology with budget near 20000 can you please suggest some?

Abhishek Jain (Mod)

Hi Megha,

In double door there are very few good options that you can get. I found only one:

Haier HRF-2674BS-R (Flipkart Link: http://fkrt.it/wVx67!NNNN ) ... however, I do not think this one has inverter technology.

Others are 2 and 1 star rated models which I would not recommend.

In Single Door, LG and Samsung are the only brands that have inverter technology, but then Samsung models are less than 200 lts and LG has only one model of 270 lts in single door with inverter technology compressor.

I could not find too many single door models as well, but you can look at this one:

Electrolux EN255 (Flipkart Link: http://fkrt.it/VVOuMTuuuN ) ..... this one is a BEE 5 star rated model and is highly energy efficient.


thank you so much Abhishek


Hi Abhishek,
Your website is good. Very nice information is provide on electronic appliances, I want to purchase a new double door fridge of 300-350 Lt capacity and my budget is between 25k -35k. I read about inverter technology.
1. does whirlpool and Godrej has inverter technology?
2. How is performance of Haier bottom mounted refrigerator?
3.Samsung convertible fridge life varies with conversion from freeze to freezer?

Abhishek Jain (Mod)

Hi Shraddha,

Here is my response to your questions:

1) Whirlpool does not have inverter technology. Godrej does have some models (but not a lot). But even without inverter technology, they have been able to improve their refrigerators for electricity consumption. However, Inverter Technology has lot many other benefits as well.

2) User response to Haier bottom mounted refrigerator is good. But they are not BEE star rated so I cannot comment about their energy consumption.

3) I do not think life of Samsung convertible fridge depends on conversion. They use inverter technology compressor whose speed can be varied easily. So freezer to fridge conversion should be smooth.

By the way if you are looking for top freezer models, you can look at these:

Hi Abhishek! Let me start by saying that this is the only site that has helped me make definitive decisions on my big ticket item purchases! Your depth of knowledge is exemplary. Keep upgrading it for our benefit !!
So we're suffering from a 8 year old fridge that I recently realised is costing me almost 1500 rs a month to run it. I saw the electricity meter consumption at 2.3kw when only the fridge was running. I was shocked. The irony is that we now want an ever bigger fridge (500-600 litres) and hoping that the bill will reduce . Is this possible? In most retail stores, I just see LG and Samsung. But I did some research on haier and it seems to be a better choice in terms of value for money. I'm looking at Haier HRF 618 SS vs Samsung RSA1SHMG. Can you please help us reach a decision ! Thanks! Preference is storage capacity, low powet consumption ,energy efficiency,good warranty.

Abhishek Jain (Mod)

Hi Neelesh,

I am happy that this site has been of help to you.

Seems like your existing refrigerator is consuming no less than 4-5 units a day. The newer BEE 3 star rated refrigerators of size range 500-600 lts would consume just about 1 unit a day. There are no BEE 4 and 5 star rated models in this size range as per our data. Side by Side models are not rated on BEE rating and their data is not available, so I cannot comment much on their energy efficiency. But if you want top freezer model, then you may look at these:

Hitachi R-V610PND3KX-(INX) (Flipkart Link: http://fkrt.it/VxX2XTuuuN )

Sir I am planning to by LG 190ltrs single door refrigerator GL-B201APOX refrigerator does it save electricity bill can I buy it

Abhishek Jain (Mod)

I am not able to find this model on BEE website https://beestarlabel.com/Home/Searchcompare ..... But on LG website the star rating is 4. And a 190 lts model from LG with BEE star rating of 4 would consume about 164 units a year. Which sounds good. So it is electricity saving.

Lucky Kumar Jain

Tnks sir


At night when the door of the refrigerator is closed how inverter refrigerator runs in same speed through out the night or its speed varies?

Abhishek Jain (Mod)

Hi Aditya,

Inverter compressor varies speed depending on the heat load. Heat can come inside the refrigerator from the refrigerator body as it is in contact with outside air. A lot depends on the insulation of the refrigerator as well. But yes, the speed will vary depending on the heat load. It may remain constant if the heat load is not varying much at night. But if something happens and there is additional heat load, then it may vary the speed.


I want to purchase single door refrigerator with invertor technology about 270, 290 ltr. Plz suggest me about best model in single door with invertor technology.

Abhishek Jain (Mod)

Hi Kulbir,

Usually single door models are less than 250 lts. And on top of that only LG and Samsung have inverter technology in single door. So your choices are very limited. And I could find only one model that matches your requirement, and that is LG GL-B281BHAI


Hi Abhishek,
I am planning to buy https://www.flipkart.com/whirlpool-185-l-direct-cool-single-door-refrigerator/p/itmerpz6fhzhdz5e?pid=RFRERGFFDPS5VHHR&srno=b_1_12&otracker=nmenu_sub_Appliances_0_Single%20Door&lid=LSTRFRERGFFDPS5VHHRYJASW0

Abhishek Jain (Mod)

It's rated electricity consumption would be 195 units a year as per BEE label. This model is fine for small family and basic needs. Although I would say that it would be better if you go for a BEE 5 star rated model. This is a BEE 3 star rated model.


Hi Abhishek,
I am planning to buy double door refrigerator, Can you please suggest which one is best in the given below
Godrej RT EON 261 P 3.4 or
Samsung RT28K3043S8.
Thanks in advance.

Abhishek Jain (Mod)

Both the brands are good brands. Energy efficiency (electricity consumption) wise both are equally good. But Samsung model has inverter technology which I think is a better technology in general. So I would say Samsung RT28K3043S8 would be my preferred choice.

नमस्ते सतीश जी,

आपने जो मॉडल चुना है वह BEE 4 star रेटेड है| यह काफी अच्छा मॉडल है और काफी कम बिजली खायेगा| इसमें Inverter technology compressor है जो सब्ज़ियों और फलों को ताज़ा रखने के लिए काफी अच्छा है| यह power inverter के साथ भी अच्छा चल सकता है और इसमें voltage stabilizer की ज़रुरत नहीं है| अगर आपको यह मॉडल अच्छा लगा है तो आप इसको ज़रूर लें|


Dear Abhishek,

We are looking at buying a refrigerator with 400 to 500 liters capacity. Need good quality plastics inside and good quality toughed glass trays. We are non-veg. We do store 6 water bottles. We also store big vessels in the refrigerator. Need atleast 2 to 4 shelves inside. Atleast a 3 star refrigerator.

Can you suggest which would be the best brand among LG, Sharp, Hitachi, Samsung, and Godrej. Also, if you could help us with the models in these brands.

Thanks for your help.

Abhishek Jain (Mod)

Hi Ali,

I will share some personal experience of shopping for a refrigerator. When I went to the market, I could only find Samsung, LG, Whirlpool and Godrej in regular stores like Croma, Reliance Digital, etc. So if you want other brands, you will have to look at their specialized store. Now from what I observed: LG is highly energy efficient, but I think Samsung has better (tougher) glass trays. However, based on my experience with Hitachi (at my in-laws place), I found Hitachi to be good in that aspect. But efficiency wise the best models are in LG and Samsung. Finally I personally went for Samsung. But all these brands are comparable brands with their own pros and cons and I cannot say that one of them is the Best because it truly depends. They have brand value because they are good.

Another observation was that LG had more shelves while Samsung had less. But that meant that bigger vessels were easier to fit in Samsung because it had less shelves. Samsung had option to put in more shelves but that was at extra cost. All this made me realize that one has to figure out what kind of vessels will be kept in refrigerator so that one can optimize the option. Every refrigerator out there will have 2-3 shelves, but based on the size of vessels, you will have to figure out the right model.

Here are some BEE 4 star rated models:

Can you give me a rough guide to the electrical saving using a fridge with inverter technology please; how many kwh less?

Abhishek Jain (Mod)

Hi Barrie,

kWh consumption of a fridge depends on the size of the fridge you are using. Without knowing the size no one can tell you how many kWh less. But one thing I can say confidently that you can get about 20-30% savings if you go for inverter technology.

Karthick Narasimhan

Hi Mr. Abhishek,

Great work... Keep it up..

I am planning to buy a new refrigerator.. Prefrebly single door... my requirement is, it should be inverter type and frost free... please suggest me a good brand and model..



Abhishek Jain (Mod)

Hi Karthick,

Single door or Direct Cool refrigerators do not have "frost free" feature. If you want a frost free refrigerator then you will have to go for a double door refrigerator. Also do let me know the size of refrigerator that you are looking for and you budget so that I can give you some suggestions. Difficult to tell models without that.

Karthick Narasimhan

Hi Abhishek,

Thanks for you prompt reply. My budget is 25000/- (maximum) and the size between 200Ltrs and 300Ltrs. Please suggest a model which should have Inverter type and Frost free.



Abhishek Jain (Mod)

Hi Karthick,

I think LG GL-I292STNL (260 lts model) with BEE 4 star rating would be a good buy (you can check it on Amazon over here: http://amzn.to/2f3BknI ). It is an inverter type frost free model with great energy efficiency. Otherwise in other brands Godrej RT EON 261 P 3.4 is a good model with 260 lts and BEE 3 star rating (Amazon link: http://amzn.to/2i4csjD ). Samsung RT28K3043S8 of BEE 3 star rating and 253 lts is also a good model (Amazon link: http://amzn.to/2i45T0L ).

Karthick Narasimhan

Hi Abhishek,

Thank you. As you suggested, i will go with LG GL-I292STNL (260lts model).

Once again thank you for your kind advice.




Hi, Can anyone let me know whether the inverter that converts AC into DC is built in the compressor or the inverter kit is installed separately in the refrigerator ? Because the company gives 9 years warranty on compressor only.

Abhishek Jain (Mod)

Inverter is built in the refrigerator. You need not buy anything else with it.

Vineeth Venugopal

I have a budget of around 33k, please suggest a frost free refrigerator above 270L, (4* rating and inverter technology)

Abhishek Jain (Mod)

These are the models that I could find:

Godrej RT EON 290 SD 4.4
Samsung RT30K37547E

Vineeth Venugopal

Samsung RT30K37547E
these are the 2 i found. Do you suggest any other models or is any one above a good bet to go for ?

Thanks Abhishek

Abhishek Jain (Mod)

You can check these:

Godrej RT EON 290 SD 4.4
Samsung RT30K37547E


Could you please tell me if a Inverter Refrigerator can run on Inverter power?? The sales person told me that LG Inverter Fridge will consume max. power of two 60W CFL Bulbs and can run on Inverter. Is it true??

Abhishek Jain (Mod)

Inverter Refrigerator can easily run on Inverter Power. There should be no challenge in it.


Hi Abhishek. We're planning to buy an Electrolux ETB2300MG door refrigerator. Do you have any idea what the unit meant for "Nutrifresh Inverter"? Can we save electricity from it or it means that the freshness of the contents in the ref stays fresh for a long time?

Abhishek Jain (Mod)


I have no idea what is "Nutrifresh Inverter". In general inverter technology keeps temperature quite balance which should result in longer life for the food kept in it.


Hi Abhishek, am planning to buy a double door refrigerator preferably a Bottom mount refrigerator. I have finalized two models
1) Haier HRB 3404. Please let me whether this model has inverter technology compressor?
2) SAMSUNG RT34K3943S8, with convertible freezer.
Which is the best? N please add if there any additional features

Abhishek Jain (Mod)

Haier HRB 3404 is inverter compressor refrigerator. It is mentioned on their website. Also as we do not have data of bottom freezer models, I cannot comment which is more energy efficient.


I need to buy a bottom mount refrigerator that has good enery efficiency and provide a good life for the purpose of usage for storing vegetables and daily usages for a family of 4,i have selected Panasonic Frost Free Refrigerator NR-BW415XSX4 whats ur opinion,

Abhishek Jain (Mod)

Bottom mount refregerators are not yet rated by BEE so we do not have much data on their energy consumption. So I cannot tell if this model is energy efficient or not. But as long as it has inverter technology compressor, a model would be efficient. This model has inverter compressor as well as Panasonic's Econavi sensors. So most likely it will be very energy efficient. Panasonic is a good brand and so you can certainly go for this model.


Hi Abhishek, I am planning to buy a refrigerator with good brand value and it should be energy efficient in the range 250 litre to 310 litre, my budget is upto 32k, could you pls suggest me best refrigerator in this range. Also previously I read your article and reviews and I came to know that LG and Samsung are the top brands among these all, as these are the only tht having invertor compressor technology, but today when I see your top ten list, it shows whirlpool model is at no. 1 position, does whirlpool also having invertor technology? , also whether it is having convertible fridger option? .Can i go with Whirlpool as it is listed at no. 1 position or LG and Samsung are the best? If I want buy LG or samsung which is the best between two and which model.
Could you pls help me out in this.


Abhishek Jain (Mod)

Hi Vijay,

Whirlpool does not have inverter technology, but then that does not mean that they cannot make energy efficient refrigerators. And the list above does not include any "subjectivity" or "opinion" to be precise. It is purely based on data. Whirlpool has a technology called 6th sense where they use sensors to optimize energy consumption. However, if you ask my "opinion" then I would still say that Inverter Technology is more promising.

Also I cannot make a judgement that a particular brand is the "best" brand because it is very subjective. Brand value builds up on the basis of experiences people have with a particular brand. Some people may have very good experience with Whirlpool, some may have it with Samsung, Some with LG. So there is no formula to come up with a best brand. Frankly, Whirlpool, LG and Samsung all three are market leaders. If you go in any electronic store, you will find that most of the models on display are from these three brands.

By the way here are the most energy efficient models that I could find in your budget and in your size range:

Samsung RT30K37547E
Godrej RT EON 290 SD 4.4
Godrej RT EON 261 SD 4.4


Thanks Abhishek.., thank you very much!!! One more thing I want to ask, I hv seen many families in my area switched off their fridge daily when not in use to save electricity, I do not think it is the right practice to do so.., it may affect the life of refrigerator.. Am I right?

Abhishek Jain (Mod)

It will not affect the lift of the refrigerator, but then it beats the purpose of having a refrigerator. The main purpose of refrigerator is to keep food fresh for long (a few days). If you switch it off daily then the food will go bad. And if you do not need to store food/vegetables for long, then you do not need fridge (just for cold water, a water cooler is good enough).


hi there!what about panasonic brand?is it good too?it has an inverter technology too?

Abhishek Jain (Mod)

Panasonic is a good brand. It does have inverter technology.


Hi ,

I am planning to buy LG GL-I292RPZL is this a good choice what you think ?

and whats is GL-I--- , GL-M--- , GL-D--- , GL- F--- stands for ?

Abhishek Jain (Mod)

Hi Tej,

I am not very sure about LG's naming convention. But GL-I292RPZL is a good model. You can go for it.



I have Planned to buy LG -GL-I292STNL(Titanium) 260lts . Is the model gud and also i would like to know much of power consumption will happen.Whole idea of buying the fridge is bring down the electicity bill.

Thanks in advance


Abhishek Jain (Mod)

It is a BEE 4 star rated refrigerator and as per BEE data it would consume about 194 units in a year (you can assume 20-30% extra based on your usage). Looks like a great model for energy efficiency. You can certainly go for it.


Hi, I want to buy double door fridge in capacity of 400-500 Ltr, please suggest which will be better in terms of electricity and utility wise. my preference brand is Samsung.

Abhishek Jain (Mod)

You can look at any of these:



I went market for suvery and saw, LG has more feature than samsung, in terms of space utilization .... I quite confuse now in Hitachi/LG/Samsung


What about if I go for Hitachi 3 doors , as heard that power consumption is very less.. Please suggest.

Abhishek Jain (Mod)

Power consumption is not brand specific, it is model specific. A model from Hitachi can be better or worse as compared to any other model from any other brand. 3 door models are not rated by BEE (Bureau or Energy Efficiency in India) so I cannot comment on their power consumption. Any refrigerator with inverter technology compressor should be good. As far as double door models are concerned, LG and Samsung are the only ones that have BEE 4 star rated refrigerator in 400-500 lts category with inverter technology compressor. You can look at these:


If you are a vegetarian, then do look for SMART convertible feature in the models (Samsung has more models with this feature and it helps you convert freezer into fridge if needed). This feature also saves a lot of electricity when you convert freezer to fridge. It also has options to switch off either freezer or fridge individually when not in use.


Thanks Sir, information is very useful..


Hi I want to buy side by side refrigerator in 600- 700 Ltr, plz suggest me the best refrigerator available in the market.

Abhishek Jain (Mod)

Hi Ashu,

Side-by-side refrigerators are not rated by BEE and thus we do not have any data to compare. All I can say is that it is good to buy a refrigerator with inverter technology. You will get models in LG, Samsung, Hitachi and Haier with inverter technology in side-by-side models.


I have gone through your post is really appreciable am planning to buy fridge.I live in the Vidharbha area of Maharashtra where summer is really hot.I need your help in finalizing my fridge purchase.
1) We have vegetarian family of four members. which capacity of fridge will be sufficient for us ?
2) Which will be good buy for me , single door vs double door ?
3) Does it is good to switch off fridge for few hours in day ?
4) Please suggest good brand and model which suits my requirement and budget. I am not much inteerested in features provided but want a durable and trouble free product. I have budget of around 25K.
Thanks in advance

Abhishek Jain (Mod)

Here is my response:

1) A lot depends on your storage habits but in general 250-280 lts should be sufficient.

2) Choice between single door and double door depends on your budget and convenience that you want. Single door models are cheaper, but then it requires switching off and cleaning periodically. Double door does not need switching off for defrosting. So double door is more about convenience. However, if we look at electricity consumption, a 250 lts double door will consume less electricity (due to recent technology improvements).

3) Technically switching off fridge is not an issue. But then the whole purpose of having a fridge is lost if you have to switch off. The reason I say that is because fridge is needed to keep food fresh for a longer duration. But if you switch off your fridge, you are exposing your food to heat, which will result in spoiling of the food quickly. Now I have a fridge because I buy vegetables once in a week or two. So I need my vegetables to last that long. But if I switch off the fridge regularly, then the vegetables will not last that long. But if you buy vegetables every day, or do not store cooked food for next day, then you do not need a fridge. Frankly, if you need it only to keep cold water, it is better to buy a water cooler instead of a fridge. Your electricity consumption will be much less.

4) You can look at any of these models:




Abhishek Jain (Mod)

Here is my response:

1) The purpose of a fridge is to keep food from getting stale quickly. Because of the cooling, food lasts longer. But if you switch off the fridge at night, then the whole purpose of keeping a fridge is lost. And in fact, if you can live with switching off a fridge at night, then you don't really need a fridge. Better not use it and save a lot of electricity. Switching off may not harm compressor life, but then switching off means that you do not have a real need of a refrigerator.

2) I am not sure about the plastic mats and their effects.

3) It is not necessary to have a stand, but then with a stand it is easy to move a fridge even if you want to clean the area behind it or around it.


Hi Mihir,
I live in the middle east. Planning to return to India. I use a Toshiba refrigerator here and have been using it for nearly 10 years. Would love your opinion on Toshiba in India. I am looking for a fridge with inverter technology, 2 door between 400 and 500 ltr capacity.
