Direct Cool vs Frost Free Refrigerator

Are you trying to decide between a direct cool and a frost free refrigerator?

Choosing the best refrigerator for your home requires a lot of research. If you want to get the best value for your money, you should be well-equipped with the latest technologies in refrigerators.

Need to know what are the differences between those two technologies?

Here is the lowdown on how both of them work and how they differ. This article will pull you out of the confusion about which would be a better pick for you.

Read on to learn everything you need to know about direct cool and frost free refrigerators.

What is a Direct Cool Refrigerator?

As the name says, in a direct cool refrigerator the air circulation happens naturally inside the device. This natural convection process creates an uneven distribution of temperature in and around the freezer compartment. These units have a defrost button inside that you need to activate manually to defrost the ice accumulation inside.

You can commonly see this kind of technology only in single or double door refrigerators.

What is Frost Free Refrigerator?

True to its name, a frost free technology literally keeps your refrigerator free from the frost. Unlike direct cool devices that use a natural process of convection, these appliances use electric fans for the circulation of cool air. These fans aid in evenly distributing the cold air within the fridge and freezer compartments of the unit, further preventing ice formation. This cooling technology is also known as a convention or indirect cooling.

The other perks of frost free refrigerators are – that they come with certain advanced features, including a timer and a thermostat. The thermostat monitors the temperature inside the fridge continuously and automatically cuts off the power supply when the appliances reach the desired temperature. Some models come with a heating system that melts the ice that possibly gets formed inside.

1. Effectiveness

If you want your food items to stay fresh for a long time in the refrigerator, then the uniform circulation of cool air is a must. In direct cool refrigerators, the uneven supply of cool air, ice formation, and the fragments of manual frosting reduce the chances of food remaining fresh.

In frost free refrigerators, the technology allows your food to stay fresh for a longer period.

4. Energy Consumption

When compared to a frost free refrigerator, a direct cool device consumes less electricity. This is because it does not use any external fans, unlike the frost free models, for air circulation. Hence, it requires less power.

On the other hand, since frost free refrigerators come with external fans for air circulation and a heating system, they require more power. Moreover, these prevent the ice formation and melt any possibly formed ice. Hence, these units consume more electricity.

5. Number of Doors

Number of DoorsDirect cool technology refrigerators are mostly available in single-door models. However, few double door units also come with this technology.

The frost free technology is available in refrigerator models with double door, triple door, and side-by-side door models. Moreover, you can segregate your preference by choosing one from the wide range of designs and specifications.

Triple door frost free fridges are not as energy efficient as their counterparts.

6. Cleaning Issues

Cleaning Issues

Having a direct cool refrigerator calls for a lot of cleaning coupled with great efforts. You need to manually activate the defrost button inside the unit to defrost the ice accumulation. Not only that, but you should also clean the residues left behind by the manual defrost process. If you think that is the end of the cleaning chores, then you are wrong. These fridges have coils at the back of the unit that gets exposed and accumulates lots of dust on them. Again, cleaning the dust, dirt, and grime regularly becomes your responsibility. Any negligence towards this will lead to a malfunction of the coils, further affecting the appliance performance.

When we talk about frost free refrigerators, there is no hassle of cleaning as such. The auto defrost option in the unit does all the job for you. The rear sides of these models remain covered.

Since direct cool refrigerators use only natural convection processes and not external fans, they do no encounter any heating issues.

We all know that frost free refrigerators have external fans for uniform circulation of cold air and a heating system to defrost the ice. Hence, there are possible chances for these parts to encounter heating issues. Although the heating does not have any negative impact, it is essential to inspect the freezer compartment regularly (annually).

Also, it is advisable to keep your unit at a certain distance from the wall to ensure the back of the fridge has enough room for heat disposal.

3. Do frost free fridge freezers need defrosting?

Ideally speaking, a frost-free refrigerator does not need manual defrosting. This is because it has the mechanism for automatic defrosting without the user’s intervention.
