制冷系统需要进行计划检修,或者因制冷机、辅助设备、阀门发生故障需要修理时,为了减少环境污染,都必须将制冷剂从制冷系统或某一局部取出或转移到某一容器中储存。假如:要排入备用钢瓶内,要估计到备用钢瓶的储存容积应大于制冷系统的制冷剂液体的容积,保证容纳得下才行。另外,备用瓶 Refrigeration systems require scheduled overhauls, or when refrigerators, auxiliary equipment, or valves fail and need to be repaired to reduce environmental pollution, the refrigerant must be removed from the refrigeration system or from a location or transferred to a container for storage. If: To be discharged into the spare cylinder, it is estimated that the storage capacity of the spare cylinder should be greater than the volume of refrigerant liquid in the refrigeration system, to ensure that it is acceptable. In addition, spare bottles
