Direct cooling

Direct cooling

Direct cooling is to install the evaporator of the refrigerator in the box or building of the refrigeration device, and use the evaporation of the refrigerant to directly cool the air in it, and the object that needs to be cooled is cooled by the cold air. The advantage of this cooling method is that the cooling speed is fast, the heat transfer temperature difference is small, and the system is relatively simple, so it is widely used.
