The cooling system of refrigeration equipment
Qingdao cold glass display cases Small make up to tell you The cooling system of refrigeration equipment
The cooling system of refrigeration equipment, which has two kinds of direct and indirect cooling cooling. Direct cooling refrigerator evaporator is installed in the refrigerating chamber or within the building, use of refrigerants of direct evaporative cooling air, objects by the cold air cooling needs cooling. This cooling method has the advantage of fast cooling and heat transfer temperature difference is small, the system is simple, and widely applied.
Indirect cooling is to rely on the evaporation of refrigerant in the evaporator, the chiller so cold agent (such as salt water) cooling, then take cold agent input refrigerating chamber or within the building, through the heat exchanger to cool the air. This way of cooling cooling speed is slow, the total heat transfer temperature difference is big, the system is more complex, therefore, for only a small number of occasions, such as salt water ice and constant temperature cold storage, etc.
According to the purpose of cooling and use the different methods of cooling capacity, generally can be divided into cold storage refrigeration equipment used, experiment with refrigeration equipment, refrigeration equipment production with refrigerating and air conditioning with four types of refrigeration equipment. Refrigerated refrigerating device is mainly used for under the condition of low temperature storage or transport of food and other goods, including all kinds of refrigerator, cold storage, refrigerated trucks, refrigerated ship and refrigerated container, etc.
