一般氯制冷系统机房设备(高压贮液桶,冷凝器、低压循环桶、氨液分离器等)均单独设置安全阀,并接有安全排放管。当高压系统压力超过1.814MPa低压设备压力高于1.226MPa表压力后,安全阀能自动开启,将超高氨气排放至大气层,避免设备压力超过极限而造成爆炸。根据商业部《冷藏库制冷设计手册》要求,安全管放出口应高于冷库屋檐或半径50m范围以内邻近最高建筑物屋檐1m。此处冷库屋檐可以理解为机房屋檐或库房屋檐。根据手册要求,设计人员执行较为困难,现
General chlorine refrigeration system room equipment (high pressure liquid storage barrel, condenser, low pressure circulation barrel, ammonia separator, etc.) are set separately safety valve, and then connected with a safety drain. When the high pressure system pressure exceeds 1.814MPa low pressure equipment pressure is higher than 1.226MPa gauge pressure, the safety valve can be automatically opened, the high ammonia emissions to the atmosphere, to avoid equipment pressure exceeds the limit caused by the explosion. According to the requirements of the Commercial Department’s “Refrigeration and Refrigeration Design Manual”, the safety pipe outlet should be 1m above the eave of the freezer or within 1m of the eaves of the highest building within a radius of 50m. The eaves here can be understood as the eaves of the engine room or the eaves of the storehouse. According to the manual requirements, the designer is more difficult to implement, now
