How to adjust the refrigeration system of cold storage equipment to reduce operating costs

1. Reasonably adjust the operating parameters of the refrigeration system to improve equipment efficiency.

　　 The evaporating pressure and temperature of the refrigeration system and the condensing pressure and temperature are the main parameters. It is an important basis for operation and adjustment. According to actual conditions and system changes, the operating parameters are continuously adjusted and controlled to operate under economical and reasonable parameters, which can ensure the safety of machinery and storage products, give full play to equipment efficiency, and save Water, electricity, oil, etc.

　　 2. Prevent impurities from entering the refrigeration system

　　 The refrigeration system is a sealed circulating system. The refrigerant circulating in the system must be clean and free of impurities, but it is impossible to be completely clean in actual operation. This is related to the working conditions and the lack of cleanness of the refrigerant added to the system.

　　 Impurities are: lubricating oil, air, water, etc. The entry of these impurities into the refrigeration system is very unfavorable to the work of the refrigeration device and should be removed in time.

　　3. Remove dirt and frost on the heat exchange equipment in time to improve the heat transfer efficiency of the heat exchange equipment

　　 Fourth, the correct choice and use of lubricating oil

　　 Lubricating oil has a certain impact on the power consumption of the compressor and the economy and safety of the refrigeration system. The correct use of lubricating oil should be paid attention to.

　　 5. Keep the compressor in good condition

　　 After the compressor has been running for a period of time, there may be wear or damage of parts, assembly gap changes, sealing performance degradation, filter clogging, etc., all of which may lead to increased power consumption. Therefore, large, medium, and small repair plans should be arranged, and normal maintenance should be strengthened to ensure that the compressor is in good condition.

　　 VI. Start operation at night or when the temperature is low

　　The cooling load is lower than the design load most of the time. Therefore, the cooling of the compressor is not continuous. If possible, the operation mode of more operation at night can be adopted. At night, the outside air temperature is low, the cooling water temperature drops, and the condensing pressure and condensing temperature are reduced. The same cooling capacity is produced, the power consumption of the compressor is reduced, and the purpose of energy saving is achieved. In addition, most areas have implemented different day and night peak and valley flat electricity prices, making full use of lower electricity prices at night is also an important method for companies to reduce electricity expenses and improve efficiency.
