摘　　要：以上海某CO_(2)跨临界冰场中使用的桶泵供液系统为对象,通过计算低压循环桶的分离直径和容积确定低压循环桶的参数。低压循环桶分离直径的设计原则是确保蒸发器回到低压循环桶的制冷剂能够充分分离。低压循环桶容积应适宜,以保证在系统运行中不会发生低压循环桶液位过低或者液位过高的情况。Taking the bucket pump supply system used in a CO_(2) transcritical ice rink in Shanghai as the object,the parameters of the low-pressure circulation bucket are determined by calculating the separation diameter and volume of the low-pressure circulation bucket.The design principle of the separation diameter of the low-pressure circulation bucket is to ensure that the refrigerant returning from the evaporator to the low-pressure circulation bucket can be fully separated.The volume of the low-pressure circulation bucket should be appropriate to ensure that the liquid level of the low-pressure circulation bucket is not too low or too high during system operation.

关 键 词：CO_(2)跨临界制冷系统 低压循环桶 稳定容积 缓冲容积
