Specification for design and manufacture of carbon steel unfired pressure vessels for use in vapour compression refrigeration systems 蒸汽压缩致冷系统用碳钢非用火压力容器的设计和制造规范
By analyzing the cfcs & hcfcs refrigerant used in vapor compression refrigeration system , the author fined that it is more or less harmful to environment , this article evaluated different alternative technologies , and gave them a proper position in alternative fields , which also offered a foundation to reverse stirling - cycle which being used in air - conditioning 同时,如何减少制冷系统的能耗也是当今工程热物理学科的前沿课题。本文首先讨论了蒸汽压缩式制冷循环所用制冷剂对环境的危害,并深入分析替代工质的发展。
