Refrigerators are household appliances that are closely related to our lives, but few people will delve into the working principles, refrigeration methods, etc. of refrigerators. Therefore, when most of us choose refrigerators, we often choose the one the sales assistant recommends, as long as the price and size are suitable.
According to the refrigeration method of refrigerators, the most common refrigerators are direct cool refrigerators and frost-free refrigerators. Of course, there are also refrigerators that combine the above two types of refrigerators, but they are more expensive, and ordinary families basically don’t need to consider them. After all, we don’t store any high-end ingredients at home.
So, which one is better, a direct cool refrigerator or a frost-free refrigerator? The answer is: frost-free refrigerator! The advantages of frost-free refrigerators are unmatched by direct cool refrigerators.
1. Advantages of Frost-Free Refrigerators
1.1 Frost-Free Refrigerators Do Not Frost
Frost-free refrigerators do not mean they do not frost. The frost will form on the evaporator and then melt by itself through technologies such as thermal evaporation. The frost will turn into water after being heated, and will flow into the drip tray where it evaporates rapidly under the action of the high temperature generated by the compressor. All these tasks are done without our awareness.
The evaporator is located behind the refrigerator wall, and we cannot see it when we open the refrigerator door. So when using a frost-free refrigerator, there will be no frost inside the refrigerator, and there is no need to defrost manually. Once you have done it, you will know how tiring the manual defrosting is! There will be no more melted water polluting the refrigerator and the floor.
1.2 Frost-Free Refrigerators Can Reduce the Possibility of Food Being Damaged during Refrigerating
There is a possibility that the old direct-cool refrigerators will damage the food during refrigerating. This is because the temperature inside the direct cool refrigerator is uneven, and the vegetables are placed too close to the back of the refrigerator, where the temperature is very low. After a long time, they are frozen.
Frost-free refrigerators are better in this regard. They rely on fans to send cold air to every corner of the refrigerator box, and circulate the cold air. Therefore, the temperature inside the refrigerator is stable and uniform, and there is no dead corner that can not be refrigerated, and there is no need to worry too much about the food inside being damaged by freezing. Not only that, some frost-free refrigerators also have antibacterial functions, which greatly improves the safety of food.
1.3 Frost-Free Refrigerators Have More Accurate Temperature Control
Anyone who has used a direct cool refrigerator knows that there is a control knob inside the refrigerator to help adjust the temperature level. However, compared with frost-free refrigerators, it has a very inaccurate temperature control. Each level of the direct cool refrigerator corresponds to ±3℃ while the frost-free refrigerators feature more precise control accuracy up to ±0.1℃, better temperature control, and more convenient usage.

3. Summary
Objectively speaking, the advantages of frost-free refrigerators are definitely far greater than those of direct cool refrigerators. However, frost-free refrigerators also have certain disadvantages. For example, they easily take away the moisture of food. Technically, they are not as mature as direct cool refrigerators, so the failure rate may be higher than that of direct cool refrigerators.
But overall, using frost-free refrigerators can avoid a lot of trouble. If the budget is sufficient, you can also consider a refrigerator integrating direct cool and frost free technologies, that is, direct cool for the refrigerator compartment and frost free for the freezer compartment, which has good fresh-keeping and freezing effects.
