The difference between air cooling cabinet and direct cooling cabinet

2020-05-05

Direct cooling cabinet type: also known as natural convection air-conditioning. The refrigerator compartment has an evaporator, and the size of the evaporator is reasonably matched according to the size and temperature requirements of the room. The cooling method is to cool food by natural convection of cold air.

Air-cooled cabinet type: It is equipped with a finned evaporator and a set of air duct circulation components. The fan motor will form an up and down circulation of the air in the box cooled by the evaporator to achieve the purpose of cooling. Because the cold air is blown in, it does not cause the frost to absorb moisture from the stored food.Therefore, the air-cooled cabinet type is also called frost-free type. In fact, frost-free is just that there is no frost on the surface of the inner wall, and the frost on the surface of the evaporator is still frosted, but it is automatic defrosting without manual defrosting.

The direct cooling cabinet and the air cooling cabinet have different main performance indicators due to the different cooling methods: the direct cooling cabinet has low power consumption, low noise, low price, and preservation of refrigerated food; slow speed, poor temperature uniformity, and manual defrosting.The air-cooled cabinet has a fast freezing speed, no frost (automatic defrosting), food preservation, and good temperature uniformity; but it has large power consumption, high noise, and high price.
