Use Refrigerator efficiently to save electricity

Hindi Translation: बिजली बचाने के लिए फ्रिज का कुशलतापूर्वक इस्तेमाल करें

Refrigerators are one of the biggest contributors (about 15%) of a typical residential electricity bill, and efficiently operating the same can significantly impact the electricity bill. Although buying a BEE 5 star rated refrigerator is the first thing one should do, but along with that, several operating procedures should be taken care of:

1) Do not stuff the refrigerator full as it will hinder the flow of cold air thereby decreasing its efficiency. Adequate space will increase the cooling efficiency of the refrigerator.

2) Make sure that the items being kept in the refrigerator are cooled to room temperature before keeping them in it.

3) Do not open refrigerator door unnecessarily as every time it is opened, some heat enters which decreases its efficiency. Decide what you want before opening the door so that the time for which it is open is less.

4) Set the temperature to medium cool for optimum cooling and lesser electricity bill. High cool will increase electricity consumption significantly (by up to 25%).

5) Always cover any liquids kept in the refrigerator as moisture lost from the liquids can impact condenser performance.

6) Do not let ice accumulate in your refrigerator as it acts as unwanted insulation and decreases the efficiency of the condenser. Defrost the refrigerator regularly to maintain the efficiency.

7) Clean up the refrigerator regularly & make sure that dust does not accumulate on coils (back or bottom) and air intake grill (below the doors). Dust build up can make the motors work harder thereby needing lot more electricity.

8) Make sure that the refrigerator remains tightly closed when not open. Any open space will cause heat to get into the refrigerator causing motor to work harder thereby consuming more electricity. You can make sure that rubber door seals are tight by slipping a paper through it. If the paper slips easily then it needs to be fixed. You can also try keeping a flashlight inside the refrigerator and making sure that the light is not visible from outside. Else seals need to be replaced.

Old refrigerators need a lot of maintenance and can consume significant amount of electricity. Upfront investment in buying an efficient refrigerator (BEE 5 Star Rated) can help you save a lot on electricity bill which can help paying back for the upfront investment. But making sure that the refrigerator is used efficiently can help reduce electricity consumption in both old and new refrigerators.Infographic15

    Hi Abhishek
    I have changed my wish for bottom freezer. Now can you suggest few good iniverter models top freezer in 300+50 litre range from leading brands. I guess there are no BEE 5 rating among inverter models. So please models with give the best BEE 4 models and their annual energy consumption..

      Here are some models:

      Samsung RT37K37647E/HL (Flipkart Link: http://fkrt.it/PZIFGTuuuN )
      LG GL-U372JHSL (Amazon Link: http://amzn.to/2mwxnP9 , Flipkart Link: http://fkrt.it/PZVOUTuuuN )

    Which are the inverter fridge models with size range of 300-350 litres and with least electric consumption, among bottom freezer inverter models?


    • https://www.bijlibachao.com Abhishek Jain

      There are not many models with that kind of configuration, but you can look at Hitachi R-SG31BPND -(GBK) …. Panasonic has some in bigger size.

  • Abhijit Jadhav


    I want to buy Whirlpool 240 L Frost Free Triple Door Refrigerator (FP 263D PROTTON ROY, Alpha Steel), but i am confused how much electricity it will consume, please suggest me for this. And also suggest whether i should ho for 240lt refrigerator or i should buy a 200 lt with 5 star rating.


  • Sanjay Nair

    Samsung RT30K37547E is the 2nd best refrigerator under 300ltrs as per Bijilibachao. My query is …Why is the condenser coil situated at the back of Samsung RT30k37547E and it is not concealed like all modern refrigerators. What are the advantages or disadvantages of having coils exposed. Does it require regular cleaning?

    • https://www.bijlibachao.com Abhishek Jain

      Hello Mr Nair,

      I am not sure why it is not concealed. Samsung can answer that better. But I think open coils can help in getting better heat exchange unlike concealed coils. Which can result in better energy efficiency.

  • Murthi

    Hi Abhishek,
    Our fridge is Samsung model RT231VSGI. Want to know how much will be its electricity consumption ? Is there any way to find out.
    Pl. suggest best fridge available now in market in 250-300 liter category.

  • s. arockia kavitha

    which is the suitable container for keeping things in fridge? plastics or ever silver or glass vessels?

    • https://www.bijlibachao.com Abhishek Jain

      Well ideally there should be no problem with any of them. However metals are better conductor of heat and thus will cool the content quickly. With plastics it would take more time as compared to metal (especially if you keep the container closed).

    Hi, my refrigerator using high electricity. i have whirlpool 150 ltr with 3 star rating. as measured it has been used 140-150 units every month. can you please suggest what is the exact issue with refrigerator.

    • https://www.bijlibachao.com Abhishek Jain

      Hi Sachin,

      If your refrigerator is leaking electricity then it will get heated up at some parts of its body. Cannot tell you the exact reason for the problem (only an engineer can check that), but 140-150 units a month is super high and you should certainly get it checked.

    How much electricity consume a refrigerator per day??? I have 5 star 180 littr refrigerator

    • Bijli Bachao Team

      It would be about 180-200 units per year as per BEE rating. So roughly about 0.5 unit per day. However it will vary with seasons and will average out at 0.5 units per day. Also the numbers are in test conditions so expect about 20-30% more than that.

  • Suunil

    Which refrigerator is best (freezer at the bottom or on top) for normal family of 4 people?

    • Bijli Bachao Team

      Freezer on top is more energy efficient. Also BEE rating is not available for bottom freezer models yet. If you are going for freezer on bottom, do look for inverter technology compressor in it.

    How much electric unit consumption in 24 hours. I have samsung 2115CCASA/TL/2015 model.

    • Abhishek Jain

      Your samsung 2115CCASA/TL/2015 model will consume 208 units/year that is about 0.56 units/day. But please note this is as per BEE rating and these values are calculated in test conditions. In real world expect it to be about 30% more.
