Zibo cold storage installation [Shandong cold storage installation] Jinan cold storage installation - What are the less commonly used defrosting methods of Sanhe refrigerated cold storage? Hot gas defrosting is suitable for small systems. The system and control method are simple, and the defrosting speed is fast, uniform and safe. The scope of application should be further expanded. Ultrasonic defrosting is a defrosting method with obvious energy saving. The layout rules of ultrasonic generators should be further studied to improve the thoroughness of defrosting for engineering applications. 3. Liquid refrigerant defrost. The refrigeration process and the defrost process are carried out at the same time. There is no additional energy consumption during the defrost period. The frost cooling capacity is used to subcool the liquid refrigerant in front of the expansion valve. The refrigeration efficiency is improved so that the storage temperature can be basically maintained. The liquid refrigerant temperature is within the normal temperature range, and the evaporator temperature rise is small during defrost, which has little effect on the deterioration of the evaporator heat transfer. The disadvantage is that the system is complex and cumbersome to control. Pneumatic defrost is particularly suitable for refrigeration systems that require frequent defrost. Although it requires the addition of dedicated air sources and air handling equipment, as long as the utilization rate is high, the economy will be very good.
