1 制冷装置用压力容器及其特性制冷装置用压力容器是制冷循环系统中必备的辅助设备,制冷循环系统是指制冷剂在系统中经压缩机→油分离器→冷凝器→储液器→膨胀阀→低压循环桶→蒸发器→压缩机而不断循环。制冷剂(氨、氟利昂或其它工质)是一种封闭在一个密封系统中的工作介质,
1 Pressure vessel for refrigeration equipment and its characteristics The pressure vessel for refrigeration equipment is an essential auxiliary equipment in the refrigeration cycle system. The refrigeration cycle system refers to the refrigerant in the system via compressor → oil separator → condenser → accumulator → Expansion valve → low pressure circulation barrel → evaporator → compressor and continuous cycle. Refrigerants (ammonia, freons or other working fluids) are a working medium enclosed in a sealed system,
