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 I am planning to buy a double fridge i have chosen two models 1. Panasonic NR-BR307VSX1,, 2. Panasonic NR-BL307PSX1/PSX2 ,, and whirlpool IF 355 ELT ALPHA STEEL(3S . Can you suggest which is recommended to buy.

Abhishek Jain (Mod)

Whirlpool IF 355 ELT ALPHA STEEL would be a better buy.


I was told that the inverter in my Bosh french door refrigerator shifted out?? where is this actually located on the unit? How does it get damaged in the first place??
Thanks for your help !


Could you suggest the best power saving refrigerator in 330 ltr to 420 ltr capacity.

Abhishek Jain (Mod)

Hi Moutushi,

You can look at any of these:

Hello sir

First of all, the article explains the inverter technology quite appropriately. I should thank you for that. Next, I need to install a DC inverter-based compressor for my refrigerator having 500 W inst.load on start. Is the dc inverter based compressor available in India for refrigerators? If yes, where can I find one?

Abhishek Jain (Mod)

Hi Tushar,

Sorry, I am not aware of any place where you can get an inverter compressor to replace in your old refrigerator.


Hi Abhishek,
I am planning to buy a 215ltr range fridge, and my main focus is inverter technology based compressor and the brand of course. I am confused between Samsung RR22M2Y2XS8 and Whirpool 230 VITAMAGIC ROY 5S DAHLIA (215 LTR), could you pls suggest which one would be a better selection? I am not sure which inveter compressor technology out of these two works more effectively in practical? Your expertise pls.

Abhishek Jain (Mod)

Hi Rishi,

Whirlpool has always been strong on their sensor technology. They optimize the performance of their machines based on inputs from several sensors. In the Whirlpool model you have mentioned, they are using Intellisense Inverter Compressor. They have used advanced sensors along with inverter technology compressor for energy optimization. However, based on BEE data the energy consumption of whirlpool model is 137 units annually and that of Samsung model is 133 units annually. The difference is not much. Brand-wise both are top brands and it is difficult to pick one over other. Electricity consumption of refrigerator does not depend on the compressor only and it is the overall number that one should look at. As it is the numbers from BEE are in test conditions and in real conditions the numbers would be at least 30% more. It is difficult for me to pick one. You will have to choose based on other requirements of yours regarding the type of containers that you plan to put in the fridge and the space arrangement inside the fridge.


Thanks very much Abhishek! Do you suggest any other brand/model in the category I am looking for? Your recommendations pls. Also, Help me understand pls - are these two inverter tech are comparable in terms of performance? Whirlpool Intellisense inverter tech vs Samsung digital inverter tech. If I understood it correct, intellisense inverter tech has all the benefits from digital inverter tech (varying compressor speed based on cooling load and requirements) + its further optimised due to use of many sensors. Correct me if I am wrong.

Abhishek Jain (Mod)

Hi Rishi,

You got it right. Intellisense inverter tech will have further optimization using sensors. However, the real numbers provide a better comparison, so you should look at annual electricity usage as well. Because, as I said, performance is not just dependent on the compressor but a whole lot of factors. As per data Whirlpool model would consume 137 units and Samsung model will consume 133 units. In fact, the most efficient one in the similar category would be Godrej RD Edge DIVA 212 PDS INV 5.2 which is also an inverter technology model and has annual electricity consumption of just 117 units. Godrej RD Edge Pro 210 PDS INV 5.2 would also consume just 123 units annually.

Please note that this is a very objective comparison of performance where we are comparing numbers. I am not giving my opinion which can be subjective. In terms of brand value, Samsung and LG are the largest in refrigerators closely followed by Whirlpool. Godrej is the biggest Indian brand.


I recently bought a Samsung refrigerator(RT39K5458SL) which has inverter technology.I want to know-
1)The peak power consumption(since there is no mention of power consumption in the website).
2)Can I connect to my sine wave inverter?Is there any harm to the compressor in connecting to the inverter.There is minimum to no power outage in my area.

Abhishek Jain (Mod)

I do not think it's peak current would be more than 1-1.5 ampere (or 200-300 VA if you are looking from an inverter perspective). Your Sine Wave inverter should easily be able to handle it without any issues. And there will be no harm to the compressor.


I have to buy LG refrigerator with 260ltr range 28000—33000rs which should I buy. Please suggest me whether I ho for smart inverter or inverter linear.?

Abhishek Jain (Mod)

Linear Inverter is a better technology. However, that should not be an important criterion for your decision. You should look for space and internal arrangement (if it suits your needs) and also electricity consumption (of course). You can look at these:

Abhishek Jain (Mod)

Triple door models are not rated by BEE and thus there is no data on their electricity consumption. So I can't say anything about them. But if you plan to buy Samsung model, then you can look at this one:

I want to buy refrigerator around 300 liter with inverter compressor and convertible/dual fridge .

Abhishek Jain (Mod)

Both LG and Samsung are leading brands and great brands. You can buy anyone of them. What is your budget for this fridge?


My budget is 36000 ₹
But I want to buy fridge with good space for vegetables and fruits .

Abhishek Jain (Mod)

Hi Amol,

LG has some latest models with Dual Fridge and BEE 4 star ratings, but they are a bit expensive (up to 39K). However, you can get models in Samsung and they are equally good and you can get some in your budget. You can check these:

Samsung RT34M3954R7 (Amazon Link: http://amzn.to/2kUATTc , Flipkart link: http://fkrt.it/U14TyTuuuN )
Samsung RT34M3954U7 (Amazon Link: http://amzn.to/2ykeG6f ) ... same model just the color is different.

This model is quite good, energy efficient and will fit in your budget. Otherwise you will have to check BEE 3 star rated models. I think this 4 star model is better.


I want to buy a samsung convertible refrigerator .please suggest me a energy efficient model within 35k.

Abhishek Jain (Mod)

What is the size that you need? You can get a 4 or 5 star model of 250-270 lts or a BEE 3 star rated model of about 320 lts?


It should be 5 in 1 convertible, 4 star and 320 liters

Abhishek Jain (Mod)

5 in 1 convertible starts from 345 lts. You can get 3 in 1 convertible in 320 lts. You can look at these:

Samsung RT34M3954R7 (Amazon Link: http://amzn.to/2kUATTc , Flipkart link: http://fkrt.it/U14TyTuuuN )
Samsung RT34M3954U7 (Amazon Link: http://amzn.to/2ykeG6f ) … same model just the color is different.

There are just 2 models that are in Samsung, 320 lts, 4 star and convertible.


I am planning for new fridge and my requirement is for side by side 560L
I found BPL side by side unit with water dispenser, a 4 star claimed product been sold at 45000 .. please let me if you have evaluated in recent past this product .. if not then do review this product . It's available only online stores and supported all over india through franchised services of BPL
Product model is BRS564H

Thanking uou in advance ..

Abhishek Jain (Mod)

BY the way based on data from BEE, refrigerators above 500 lts even from the best brands with best technology have at best BEE 3 star rating. And this model does not have inverter technology, so I highly doubt that this one would even be BEE 3 star.

Abhishek Jain (Mod)

Hello Mr Bhatia,

We have not evaluated BPL products in recent past. Also, side by side units are not rated by BEE so I have no ways to evaluate its 4 star rated claim. In general side by side units with water dispenser tend to leak heat through the dispenser thus increasing electricity consumption of refrigerators, and that we suggest to avoid going for such models if possible. I checked the Amazon link for this product and found that it is quite cheap and has basic features. Does not have any advanced latest features that are available in modern refrigerators like: inverter compressor, separate evaporator for fridge and freezer to give control over temperature of individual sections of the fridge. Based on the feedback on Amazon it looks good for basic features and big size for a tight budget.


looking for mini fridge. ( around 50 to 60 lit capacity) is there any inverter model available? want to go for high energy efficient model. can you suggest

Abhishek Jain (Mod)

Small fridges are not energy efficient. In fact they consume as much electricity as any other 180-190 lts model. Also there is no inverter technology in such small fridges.


jai jinendra Abhishek ji, i m having whirlpool iceberg 310 ltr fridge from last 10 year , its electric consumation is now very high , and now i living alone person and i want to sell this fridge and want a buy single door fridge, can u sugest me single door fridge with low energy consume with low price , becoz my double fridge some one offered me 6000 and i want to buy near 10-12 k . so pl advice me thanks

Abhishek Jain (Mod)

Jai Jinendra Mukesh Ji,

In a budget of 10-12K you will not get the most efficient BEE 5 star rated models (which would cost about 16-17K at least). At best you can get BEE 3 star rated 180-190 lts models. You can look at these:

Hello Abhishek Ji,
I am planning to buy a refrigerator, I do not need big size but somehow I like the looks of side by side refrigerator and decided to buy one, I have seen few models and have shortlisted two LG models
They say its some inverter linear compressor and it consumes less energy, They don't have any start rating. could you advise which one to go from above two mentioned or Should I go with some other brand like Samsung etc. Your prompt reply would be highly appreciated. Thanks & Best Regards -Rishi

Abhishek Jain (Mod)

Hi Rishi,

Side by side refrigerators do not have star ratings currently and thus it is difficult to tell their efficiency levels. However, inverter linear compressor is a very efficient technology. Although compressor is just one of the components that determine efficiency, but it is a major one. So most likely these refrigerators would be efficient. LG is a good brand and if you are liking the models then you may certainly go ahead with them.


I am planning to buy a 400L + refrigerator. I like KDN56XI30I from Bosch but i am worried about its power consumption. Product manual says that it will consume about 376 Units per year. Can you help me compare this with other 4/3 start fridge power consumption in terms of units per year? Can you also share your overall opinion about Bosch and your other recommendation for 400L + fridge. I have one concern about the width i.e. it should be < 30 inches.

Thank you.

Abhishek Jain (Mod)

Hello Mr Rajneesh,

Bosch as a brand is a very good brand, but this specific model is a BEE 2 star rated model and we usually do not recommend BEE 2 star rated model. One should go for at least BEE 3 star. What is your budget for the fridge? Also are you looking at above 500 lts or less than that is also fine. Because Samsung and Hitachi models of less than 500 lts are less than 30 inch in width.


i am planning to buy LG 270ltrs single door refrigerator model GL-B281BSDX with 4 star rating having inverter technology.

Budget anything between 75k to 130k.

We can look at Samsung or lg ... preferred models pls ?

Abhishek Jain (Mod)

I think Samsung would be better. You can choose any of these:

BrandModelAmazon Link

All these have 1) Digital Inverter Compressor 2) Sensors for performance optimization which can help reduce electricity as well and keep food fresh for long 3) All have twin cooling, so separate cooling for freezer and fridge, which helps you to alter temperature of either section individually.

You can decide between ones with water/ice dispenser based on your needs. Ideally I would not recommend going for one with dispenser because they tend to get leaky and in future may result in higher electricity consumption.

Abhishek Jain (Mod)

Hi Vivek,

LG side by side models are above 650 lts. Samsung and Hitachi will have side by side models with volume above 550 and with inverter technology. Samsung is pretty strong in refrigerators market as compared to Hitachi. Although Hitachi also has good technology, however, their service is not up to the mark everywhere. I think Samsung will be good for you. What is your budget?


Hello. Thanks at the outset for your prompt replies on this forum. I have a space of 70 cm between the counter edge and wall where i need to keep my fridge. Whats the largest size fridge that can fit into that space including door opening space. I need to go for inverter type as i have to connect to a 2kv inverter. Could u also recommend some models. Thanks

Abhishek Jain (Mod)

You also need to leave about 2 inch space on all the sides for proper air flow. So effectively you just have 60 cm width for the refrigerator. Which means that the max storage volume that you can go for is about 300-320 lts. What is your budget for this fridge?


Does Samsung RS55K5010S9 has a Stabilizer free operation ...Or do i need to buy one?

Hello, I have purchased RT30M3954R7 Top Mount Freezer with Solar Connect* 275l
Digital Inverter Technology Convertible Freezer All Round Cooling facilities.

1) What temperature I should set of Fridge & freezer in monsoon, winter & summer considering I live in Pune? 2) Also shall i use Freezer to fridge mode in case to save electricity? Please give more knowledge about same 7 how much electricity I can save by doing this?

Abhishek Jain (Mod)

Hi Piyush,

Here is my response:

1) Temperature settings depend on your need. The cooler you keep it, more will be the energy consumption. If your food items need lower temperature then you can keep it at the coolest setting. Else keeping it at higher temperature would be better. Please note the higher you keep the temperature at, slower would be the speed of ice formation.

2) You can certainly keep freezer in fridge mode to save electricity. As I said, lower the temperature, higher will be the electricity consumption. So if you keep freezer at 21 degrees, the electricity consumption will be more. In case it is kept as fridge settings (say at 5 degrees), the consumption will be much less (about 30-40% less electricity consumption of freezer as compared to keeping it at -21). But this is just for the freezer not for the whole fridge.


I am about to buy Samsung refrigerator MODEL RT28K3423S8, double door, digital invertor 253 LTS. I have heard the reviews that LG is the better one or is it my doubt on Samsung? I had a bad experience some 10 years back of a Daewoo fridge, 410 lts, which leaked gas & we could not find out the leakage & finally sold it few months later, so I am a bit worried buying these double door fridges. I have heard that the coils are on the inner side, so when condensation occures, heat does not escape & it may leak gas? Is it right? Please clear my doubt. Thank you.

Abhishek Jain (Mod)

Gas leakage can happen due to corrosion or fault in the refrigerator. It does not happen every day, even for the double door fridges with coils inside. In fact most refrigerators available in the market these days have coils inside. I have personally used one from whirlpool for 7 long years and I replaced it with a Samsung about a year back. And both have worked well for us without any problems.

Is your environment corrosive? Check with people around you if they have face AC or refrigerator gas leakage problem. Also it is not necessary that it can happen only in double door. It can happen in single door as well if the environment is corrosive.

But usually the refrigerators do not leak gas.


Thank you for your reply. Can you please throw some light on how to prevent corrosion? Our environment is not corrisive & not always humid. It does get humid during rainy seasons, but it is not much. Thank you.

Abhishek Jain (Mod)

There are corrosion protection sprays available in the market, but I would suggest that you check the applicability of the same from the brand's engineer who comes to install the fridge at your place. They would have a better idea if and how the fridge can be opened and the spray applied. Rains should not make the environment corrosive. Mostly salty and humid air or chemicals laden air is corrosive. Just humidity usually does not cause such impact to refrigerators.

I would prefer refrigerator with inverter technology , also do the bottom freezer versions and freezer to refrigerator and back versions have any effect on performance and energy consumption overall, thanks in advance.

Abhishek Jain (Mod)

Hi Vishal,

It would be difficult for me to provide data based on ratio of freezer to fridge because we do not capture this data from manufacturers. That will be a big activity for us to do right now. However, you can look at these:

BrandModelVolumeStar RatingAmazon LinkFlipkart Link
LGGL-I322RTNL3084 http://fkrt.it/aJzrlTuuuN

There are lot of things that impact electricity consumption and just bottom freezer and convertible cannot be said to be efficient or not. The performance of condenser, compressor, evaporator, refrigerant and other things combined together result in efficiency of a model. So a Bottom freezer model can be efficient or cannot be efficient depending on all these things. The data for bottom freezer models is not available from BEE and thus no conclusion can be drawn without knowing the same.


Recently,Just five days before i bought Samsung 341L Inverter technology type refrigerator,
From Last 2 -3 days,Refrigerator compressors gets tripped for 2 to 3 hours on regular intervals,
Samsung guys told us that this is process of de frost system,

I need your help,Is they are right?
Because i read that in invert er compressors runs continuously by varying different speed,

in my new refrigerator compressors gets turn off after every 04 to 05 hours,

Please suggest...

Abhishek Jain (Mod)

Hi Akil,

Ideally the compressor should not turn off if there is heat to remove from the system. If the fridge has reached the set temperature and there is no (or very less) heat flowing inside, then the compressor may turn off. But then this does not happen usually because fridge temperatures are very low as compared to outside temperatures. But how did you know that the compressor turned off? Usually the inverter compressors are very quite and you do not understand if it is running or not. But yes, theoretically they should not turn off. The de frost argument is absurd.


May I know the current usage of Samsung Rs55k5010s9 Side By Side With Twin Cooling 591 L refrigerator?

Abhishek Jain (Mod)

Do you want electricity consumption of the refrigerator or Current? Why I am asking this is because

Power = Voltage x Current

And Electricity Consumption = Power x Time

Usually brand does not provide much information. I checked the user manual as well and the information is not there. However, typically refrigerators are rated at about 350-400 Watts (Power). So current would be max 2-3 Amp (at 220 V).

As for electricity consumption, it is inverter tech model, so should not consume more than 1 unit a day.


Hi Abhishek,

May I know your opinion on Haier and Hitachi refrigerators?
Which brand would you suggest to buy with inverter technology and considering the volume requirement would be 300+L.


Abhishek Jain (Mod)

Hi Rohan,

Purely in terms of efficiency LG and Samsung (and to an extent Whirlpool) rule the rankings. These 3 are the leaders in Refrigerator as well. Hitachi and Haier at best have BEE 3 star rated refrigerators.

In terms of technology most brands these days are adopting inverter technology and also going for dual fridge where there is a separate evaporator for fridge and freezer giving a lot of control over temperatures independently of fridge and freezer. Hitachi and Haier also use this in their refrigerators. In terms of technology they very well compare with the leading brands. LG and Samsung have additionally started putting thermal retention technologies these days where the refrigerator remains cool even during power cuts. But these are good in case you have power cuts in your area. Hitachi and Haier do not have these in their refrigerators yet. Hitachi is a Japanese brand which is great in ACs and good in refrigerators. Haier is a leading chinese brand, not among the premium ones but still good.

In terms of service the big brands (LG, Samsung and Whirlpool) have wider coverage due to their presence everywhere. Hitachi and Haier may not be great everywhere.

I think Samsung and LG are the safest bet.


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:

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?


150/180 liter

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 )
