Efficiency of refrigerator is most discussed issue in household as refrigerator is the appliance which runs all day, 365 days. So better energy efficient refrigerator will benefit long term considering the monthly electricity saving. So the first question is how the efficiency of refrigerator is calculated. Clear picture on this will help us to choose the most energy efficient refrigerator.
Try our refrigerator selector to choose right refrigerator by answering simple questions without reading any buying guide.
The most energy efficient refrigerator is with the highest number of star rated refrigerators. Five star rated refrigerator are most energy efficient refrigerators. To achieve low energy consumption always prefer 5 star rated refrigerators. Usually 5 star rated refrigerators are tends to be costlier, in that case you can choose 4 star rated refrigerators. But remember 5 star rated refrigerators are best to save electricity bills. Please see while purchasing in stores sales boys may pursue to choose 4 star rated refrigerators saying that they were five star rated refrigerators last year. But it is always best to take latest 5 star rated ones are they tends to be very efficient as mentioned above ratings gets changed frequently.
As with the age refrigerators tends to consume more power. 10 years old refrigerators definitely needs to be replaced as they consume more power. Apart from 10 years back five star rated refrigerators are now rated as 2 star or 3 star rated refrigerators. Read more on refrigerator energy consumption old vs new article for more information.
Please see triple door refrigerators are not given BEE star ratings. The triple door capacity refrigerators are available in double door refrigerators. So on the basis of energy efficiency aspect strictly avoid triple door refrigerators. The reasoning is same for side-by-side refrigerators. Side-by-side refrigerators capacity is very large and meant for big families and there is no same capacity alternatives in double door refrigerators. So in that case having side-by-side doors makes sense.
Inverter refrigerators are new models in the market. Inverter refrigerators operate on variable capacity load. What exactly it means? Heart of the refrigerator is its compressor, it is like cooling engine of refrigerator. The normal refrigerator operates on fixed efficiency or engine capacity. When the refrigerator is empty - without food or in the winter very limited cooling is required. But normal refrigerator still works on full engine capacity. Well you can clearly see the energy loss.
Contrary to this, inverter refrigerator have variable capacity compressor or engine. It is like elastic rubber. Depending on the load, engine capacity varies. So in winter or when the fridge is empty the compressor operates at very low capacity and hence saves the energy. In summer the compressor operates at high capacity.
