Direct Cool vs Frost Free Refrigerator: Which is Better?



The Refrigerators have seen a vast improvement in technology.

At one point in time, we had the manual defrosting refrigerators at home.

Old timers would still remember the lashing they had to face from the boss (naturally the woman of the house) in case they forgot to push the manual defrost button before going to bed every night.

Thankfully, this is not the case today with the introduction of the frost-free refrigerators. Let us go on to look at the difference between these two technologies

Direct Cool Refrigerators vs Frost Free Refrigerators

Before going on to look at the differences between the two categories of appliances, would it not be better if we had a peek into the technologies involved in the same?

Direct Cool technology

As the name suggests, the refrigeration takes place by circulation of cool air takes place naturally without any external aid. Hence, there is no way you are able to control the temperature distribution. It is bound to be uneven.

Under such circumstances, you experience the collection of frost in and around the freezer box. You have to press a button manually to defrost this ice. You observe this direct cool technology in the single-door refrigerators.

Frost Free technology

Maybe, the person who invented this technology must have been heckled to the core by the boss. Jokes apart, this frost free technology is a fantastic invention that has made life very easy.

This technology works on the principle of even distribution of cool air inside the fridge by electric fans. As there is no formation of ice, there is no need of defrosting.

Now, let us look at the basic differences between the two technologies.

  1. If you use seal pack/box for every food item then you will not get drying out effect. I am using frost free refrigerator for 3 years & it keeps food fresh for more days than my direct cool refrigerator.

  2. How is the new Voltas ‘Beko’fridge,for which company claims freshness of vegetables for 30 days ?.Is there any technical advancement in this model ?
    Which model & company is best in 400 Litre fridge for domestic purpose ?

  3. One important difference is that ‘drying’ of stored food, irrespective whether fresh or cooked, occurs in frost free refrigerators while the same doesn’t happen in direct cool models.
