At present, the construction of domestic cold storage and cold storage cold storage is increasing. According to the needs of three different types of cold storage temperatures, combined with the cooling parameters provided by the chiller manufacturer, the relevant model selection can be carried out. In the selection stage, comprehensive consideration should be made according to the overall situation. At present, the quality is very important in the process of product selection. The refrigeration equipment is operated in a low temperature environment. A quality refrigeration product can be used for a long time. At present, the selection of the air cooler is mainly low temperature and good performance, like lubrication in the fan bearing. The oil maintains good performance even at low temperatures.
When selecting the refrigeration equipment used in the cold storage, the customer can select the appropriate refrigeration product according to the refrigeration parameter area provided by the manufacturer. When selecting the refrigeration equipment, it is necessary to consider the type of products stored in the cold storage, the storage temperature requirements required by the product, and the operating conditions of the cold storage. It is also necessary to consider whether the selected cooling equipment such as the cooling fan meets the energy conservation and environmental protection and other information.
 If the temperature of the cold storage is the same, for example, if the evaporation temperature is increased at ten degrees, the cooling fan should choose a larger power. The same type of chiller is only slightly reduced at high evaporation temperatures. The reason for the decrease in the cooling capacity is that the flow rate of the refrigerant in the tube is reduced, causing the heat transfer coefficient in the tube to decrease, resulting in a slightly lower heat transfer coefficient of the cooling fan. The selection of the evaporating temperature and the cooling capacity, etc., which can be selected according to this, is selected in the selection of the cooling fan, and the selection of the cold storage refrigeration equipment such as the cooling fan is selected as a whole.
 In addition to knowing the evaporation temperature, the temperature of the cold storage should be known. After the cooling fan is selected, the amount of cooling that can be transmitted depends on the difference between the evaporation temperature and the average temperature of the inlet and outlet of the cold storage.
