本文介绍大型冷藏库制冷工艺设计中易于遇到的几个问题:如制冷系统选用什么形式的压缩机;多层冷库供液不均;同一冷间多组冷却设备供液不均;当冷间达到设计温度氨泵停止供液时,低压循环桶回液量增大液面难以控制等。处理好这些问题是制冷系统正常运行的基本保证。
In this paper, several problems that are easy to be encountered in the design of large-scale refrigerator refrigeration are introduced: what kind of compressor is used in the refrigeration system, uneven supply of multi-storey refrigerator, uneven supply of liquid in the same cold room, Ammonia pump to achieve the design temperature to stop the liquid supply, low pressure circulating liquid back to the liquid level increases difficult to control and so on. To deal with these problems is the basic guarantee for the normal operation of the refrigeration system.
