The characteristics and differences between air-cooled refrigerated cabinets and direct-cooled refrigerated cabinets

The difference between the air-cooled refrigerator and straight-cooled refrigerator refrigeration display cabinet first simply: air-cooled with a fan, automatic defrost, no icing. Direct cooling, no fan, icing, manual defrost.

Direct cooling: also known as the natural convection type of cold air. There is an evaporator in the cooling room, and the size of the evaporator is reasonably pitched according to the size of the room and the temperature requirement. The cooling method is through the natural convection of cold air to cool the food.


Air-cooled: There is a finned evaporator and a set of air duct circulation components inside. Fan motor will be cooled through the evaporator to form the air inside the box up and down circulation, to achieve the purpose of cooling. Because the air blown into the cold airflow, will not lead to the absorption of water from the stored food and frost. So the air-cooled type is also called frost-free, in fact, no frost is only the inner wall surface without frost, the evaporator surface is still frost, but without manual defrost but automatic defrost.


Direct-cooled and air-cooled due to different refrigeration methods, the main performance indicators are also very different: direct-cooled power consumption, low noise, low prices, refrigerated food preservation; slow, poor temperature uniformity, manual defrost. Mainly in the Chinese and European markets. Air-cooled type freezing speed, no frost (automatic defrost), food preservation, good temperature uniformity; but high power consumption, high noise, high prices.
