制冷系晚的自動控制是提高制冷品質的有效手段之一，采用自動控制可以保證庫穩定，避免不必要的低溫，并可使食品在貯藏期間質量穩定，減緩食品表面水分的蒸發，此外采用自動控制還可以使冷庫制冷系統運行中的溫度、壓力，液位等狀態參數保持在要求的范圍內，保證系統安全高效運行，據統計冷庫制冷系統采用自動控制比手動控制可節能15%-20%

The automatic control of the refrigeration system is one of the most effective means to improve the quality of refrigeration. The automatic control can ensure the stability of the library to avoid unnecessary low temperature and stabilize the quality of the food during storage. The automatic control can also make the evaporation of the surface moisture of the food. The temperature, pressure, liquid level and other state parameters in the operation of the cold storage refrigeration system are kept within the required range to ensure safe and efficient operation of the system. According to statistics, the automatic control of the cold storage refrigeration system can save energy by 15%-20% compared with manual control.
