The rising demand for energy-efficient refrigerators


 

The refrigerator you buy can have a big impact on your energy bills. Refrigerators run non-stop, and their energy costs get troublesome in the long run. The good news is that modern-day refrigerators have become much more energy-efficient over the years, helping people cut down on utility bills.  

 
 

The energy is used by the refrigerator to pump heat out of the cabinet and keep it cool. A slight amount of energy is also used to keep the cabinet from leaking, for defrosting and to light up the interior. The energy-efficiency of a refrigerator is measured in the volume cooled per unit of electric energy per day. i.e,  

Refrigerator Efficiency = Volume Cooled (ft3) / Unit Electrical Energy per day (kWh)  

An energy star rating is an authorized symbol approved by the Government that displays the refrigerator's energy-saving efficiency. The energy star label is mainly used to reduce the emission of different pollutants like greenhouse gas from the refrigerator and save the environment. The energy efficiency of even the best refrigerators and freezers has improved majorly over the past three decades with technological innovations and the rising consciousness towards sustainable choices. In current times, one should go for the maximum star refrigerators, like 3-star refrigerators or 5-star refrigerators.  

The Panasonic double door refrigerator features ECONAVI sensors that can detect and analyse the conditions in the refrigerator to ensure ideal cooling without wasting energy.   

  

Let's see what kind of refrigerators are the most energy efficient!  


Refrigerators with the freezer on either the bottom or top are more efficient than side-by-side models. This is because bottom freezers use approximately 16 percent less energy than side-by-side models, and top freezer models use only about 13 percent less than side-by-side. Even some double door refrigerator models are energy efficient if they have a higher star rating. Since a double door refrigerator comes in a large size of 235 to 295 litres in capacity, its large size results in more power consumption of around 30 to 40% electricity. The water dispensers and ice makers on the door of the refrigerator increase the refrigerator's energy use by 14 to 20 per cent, despite not opening the door frequently. Manual defrosting of the refrigerator uses half the energy of an automatic defrost model, but must be defrosted regularly to stay energy efficient.  

 

Now you know that there is a direct relation between star rating and energy consumption in even the best refrigerators. So, to get the best refrigerator with maximum energy efficiency, you must look for a refrigerator with higher stars. Nowadays, 5-star refrigerators are costlier to buy, but try not settling for anything lower than a 3-star refrigerator. Go for the refrigerator that is best yet within your budget. A star rating higher than a 3-star double door refrigerator has a more efficient compressor and is insulated better to evade heat loss. Hence, they are very efficient in energy saving and a popular choice these days. If you and your family are using an old refrigerator, you must upgrade to a more efficient modern model to save energy and money eventually.
