A refrigerator is a fresh-keeping cabinet that combines refrigeration and storage. It is common in supermarkets, convenience stores, catering and other industries. It can mainly be used to store vegetables, fruits, cold drinks, fresh meat, cooked food, frozen food, etc. Refrigerators on the market can be divided into many types, which can generally be divided according to the usage scene, size, and refrigeration method. Today, I will mainly introduce the difference between air-cooled refrigerators and direct-cooled refrigerators.
There is no evaporator inside the air-cooled refrigerator. It exchanges cooling through hot and cold air, and sends cold air to various positions of the refrigerator through fans and air ducts. Generally, it has an automatic defrosting device, which is simple and convenient to use and clean. In addition, the temperature inside the refrigerator is uniform., the relative price of air cooling is higher, and the power consumption is relatively large. If you mind this, you can consider it more.
The direct-cooled freezer uses the natural convection of the air in the refrigerator to cool the ingredients. There is no fan inside, it is easy to freeze and needs to be defrosted manually. It is often used in large refrigerators or freezers for commercial purposes. Generally, the price is relatively cheap, energy saving, and the preservation effect is good. The disadvantage of the direct-cooled freezer is that it needs to be defrosted manually on a regular basis, and the temperature of the freezer is relatively uneven.
