The Basics To Buy The Right Refrigerator

In case of direct cool versus frost free refrigerators, no matter what type of refrigerator it is, you should always keep a check on the following features of a refrigerator before buying it –

1. Capacity

It is common to find that two types of capacities are displayed on a refrigerator – gross and net. So, you need to find out the correct usable capacity of the particular refrigerator before buying it. If you have a large family, then go for a larger capacity (450-650 L) , or else you can go for the smaller or medium one (180-250 L).

2. Star Rating And Energy Consumption

Nowadays, before buying any electronic item, customers first enquire about the BEE star rating and energy consumption of the particular product. The same is in the case of a refrigerator.

There is a term called EER, which means Energy Efficiency Rating. It shows or denotes the efficiency of your electronic appliance. You should always look for the higher-rated models. The efficiency level is directly proportional to the rating given.

Apart from the rating on the refrigerator, you should also check the kWh or the total units of electricity that your refrigerator will use in a year. Moreover, to ensure that the energy rating is authentic, you should look for the Bureau of Energy Efficiency (BEE) logo on the refrigerator.

Nowadays, electricity bills are becoming a major concern for many households as they are using or running numerous electronic items in their respective houses. So, buying the correct rated refrigerator can save some of your money. Moreover, the level of electricity consumption of a refrigerator also depends on the number of times you open the door of it. Because whenever you open the door, the fridge consumes extra electricity or power to maintain the cooling temperature.

3. Type of Compressor

A compressor is a vital part of a refrigerator, as it works as the cooling unit. You can find two types of compressors in the market now- Regular compressor and inverter or digital compressor.

A normal compressor runs at a constant speed. It does not alter its speed even if cooling loss happens. But on the other hand, a digital compressor alters its speed according to the amount of cooling required inside the refrigerator. The normal compressor is fine for smaller refrigerators.

But if you are thinking of buying a larger refrigerator, then it is advised to choose the digital compressor. Moreover, the digital compressor is more efficient as compared to the normal compressor. Now days, almost all medium-sized and large-sized fridges come with the digital compressors.

4. The Add-ons

Larger refrigerators have a multi-storage capacity in them. It is evident that medium and large-sized refrigerators come with many advanced features attached to them such as deodorizer, in-built voltage stabilizer, door alarm, touch panel, etc. Some refrigerators also come with a cool pad, which helps to keep the food items fresh during power cuts.

So, you should look for the right and latest features before buying a refrigerator or any other electronic item. But the add-ons will pull extra money out of your pocket too.

5. Technology used 

As we discussed above, direct cool refrigerators use a conventional method of cooling. So, frost starts to appear at certain places. But it is not in the case of any frost free refrigerator.

As the direct cool refrigerators provide an instant cooling facility, they are the right fit for industrial purposes while the frost free technology is suited for residential use.
