Electricity Saving Tips For Homes And Offices

Use Refrigerator efficiently to save electricity

By on April 22, 2016

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,

This is Somantak here again. In your list for best refrigerator of 2017 under 300L category Whirlpool Neo DF305 Roy Plus 292L (non-inverter compressor) is placed 2nd in terms of energy efficiency where as the 4 star Samsung & LG models (inverter compressor) have higher yearly unit consumption.
So is it wiser to go for the Whirlpool model instead of the Samsung & LG inverter models as the capacity is higher and the power consumption is lower for the Whirlpool model.

Regards,
Somantak

Hi Somantak,

Inverter technology does not guarantee low electricity consumption as the compressor is just one of the components in a refrigerator and inverter technology only impacts compressor. Agreed it is one of the highest contributors to electricity consumption, but then there are other components as well. Whirlpool uses a set of sensors to optimize energy usage while using old technology for the compressor. With inverter technology, there is an opportunity to further bring down the electricity consumption, but then that comes at a cost and at current electricity tariffs, the cost will not be justified.

Now having said that, Samsung, LG and Whirlpool are leading brands in refrigerators in India. These three dominate the market. All of them are good brands. If you want to go for Whirlpool, then you may go for Whirlpool as well. It is a great brand.

Thank you for your reply Abhishek. My main concerns for buying a new refrigerator are capacity, energy consumption & price. I am not very inclined to Smart Convertible or Dual Fridge functions as I will choose a refrigerator capacity to suite my need (considering the max needed capacity) so there will not be very much requirement for converting the freezer into fridge. Also earlier I was opting for the inverter technology only to minimize the power consumption, but this whirlpool non-inverter model is consuming lesser energy than the inverter ones from Samsung & LG whereas providing the maximum capacity among them.
Could you please provide me the price of Whirlpool Neo DF305 Roy Plus.

Regards,
Somantak

Based on my sources (which are mostly online) it should cost you about 31K.

Hi Abhishek,

I have a 14 yrs old Samsung 230 Ltr. double door refrigerator and its working fine. Now my question is can I power it off at night for 4-5 hrs. as both of my ACs are being used together at night, would that help reducing the electricity bill or it will put stress on the refrigerator resulting in damage of the fridge?
I have plans to buy a new one next year, a 5 star one obviously. Reading all your posts to find out which would be the best to suite my need.

Thanks,
Somantak

You can certainly reduce electricity bills by switching off the refrigerator for 4-5 hrs and it will not put a load on your fridge. But then you will loose the purpose of keeping a refrigerator. Ideally if the refrigerator is not cold enough, the food does not stay fresh in it. If you do not store such food in your refrigerator, then you can switch it off. But if you do store food, then you may find it difficult (not for health of the fridge, but for the food).

Thank you for your reply. I do understand now. It seems I have to buy a new one pretty soon.
I checked out only Samsung manufactures 5 star Inverter refrigerator, no other company is there. Kindly suggest me 4 star or 5 star inverter refrigerator within 30-34k.

Thanks,
Somantak

Hi Abhishek,

Thank you for the lists. How much difference in power consumption is there between the 4 star and the 5 star ones. The 4 star ones from samsung are convertible where as the 5 star one is not. So, if the consumption difference is not much then I will go for the 275L 4 star one.

Thanks,
Somantak

10
Abhishek Jain (Mod)

The difference in power consumption is about 40 units in a year as per BEE data. In real life it would be 30% more, so about 52 units a year.

11

Also please let me know between LG and Samsung which brand is better?

12
Abhishek Jain (Mod)

Both are top brands and you can go for anyone of them.

13

Thank you Abhishek. All these refrigerator brands don't mention the power consumption, they only mention the star rating. How would one know the rated power consumption of the refrigerators of different storage capacities?

Thanks,
Somantak

14
Abhishek Jain (Mod)

The star label has annual electricity units consumption mentioned on it. They do not mention the wattage because most consumers cannot understand relation between wattage and electricity units and that is why they mention annual units.

Now many find it difficult to compare units as well. BEE wanted to use annual electricity costs for comparison, but then electricity tariffs are slabbed (vary based on usage) and they also vary from state to state. And that is why annual electricity costs was difficult to mention, and that is why they mention annual electricity units consumption. It can give better idea as compared to mentioning the wattage (which is sometimes deceptive way to compare two refrigerators).

15

Thank you so much sir. Now its clear to me.

hi,
I want to buy a double door refrigerator (price range upto 20K). Can you suggest me a good one.
How about these two :
Whirlpool 245 L NEO FR258 CLS/ROY PLUS WINE GLORIA 2S,
Samsung 253 L RT28M3022S8-HL/ RT28M3022S8-NL, Elegant Inox
But power consumption will be high for these two as they have 2 star BEE rating. Can u please suggest me a good one.

Thank you

17
Abhishek Jain (Mod)

Hi Manikanta,

It is quite difficult to get a better efficient frost free refrigerator in price less than 20K. You will have to increase your budget to about 21-22K.

18

That should be OK... Please tell me the best refrigerators.

Thank you

I want to go for double door refrigerators, which is the best. I have whirlpool(WHIRLPOOL-NEO DF305 ROY PLUS 4S) and LG (LG 284 L Frost Free Double Door Refrigerator (GL-I302RTNL, Titanium)) in mind, could you please suggest me the best one and also with respect to power consumption between these two brands.

21
Abhishek Jain (Mod)

From an electricity consumption point of view Whirlpool Neo DF305 would be slightly better as its annual electricity consumption is rated at 185 units whereas that of LG GL-I302RTNL is 198 units. But I still feel that Inverter Technology is better and the difference is not much.

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?

38
Abhishek Jain (Mod)

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.

39

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.
Thanks,

40
Abhishek Jain (Mod)

Hi,

We do not have data for Samsung model RT231VSGI, so I cannot comment on the electricity consumption of the same. You can use an energy meter like Kill-A-Watt to find out it's electricity consumption (you can know more about it over here: https://www.bijlibachao.com/electricity-bill/kill-a-watt-meter-p3-power-analyzer-powermeter.html ).

You can look at the list of top most efficient refrigerators on this link: https://www.bijlibachao.com/top-ten-appliances/what-are-best-refrigerator-fridge-lg-samsung-whirlpool-india.html

s. arockia kavitha

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

42
Abhishek Jain (Mod)

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).

43

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.

44
Abhishek Jain (Mod)

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.

45

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

46
Abhishek Jain (Mod)

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.

47

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

48
Abhishek Jain (Mod)

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.

49

Thanks

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

51
Abhishek Jain (Mod)

Hi,
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.

52

How much electric unit consumtion in 24 hours

53
Abhishek Jain (Mod)

What size of refrigerator? and What is the BEE star rating? Also what is the year of purchase?
