替代冷媒在中央空调冷源设备中的应用现状

ALTERNTIVE REFRIGERANT HCFC-123、HCF-134a USING IN AIR CONDITIONING COLD SOURCE EQUIPMENT

介绍氟利昂制冷剂对大气环境破坏及国际组织所采取的保护措施问题 ,提出《蒙特利尔议定书》、《框架公约》相互矛盾之处 ,列出了替代制冷剂的热力学参数及修正后的环境特性参数和评价标准 ,并从环境保护和使用两方面评价 HCFC-1 2 3、HCF-1 34 a替代冷媒。

This paper introduces the problems of freon refrigerant damaging atmosphere environment and the protective measures taken by the internatonal organizations.It points out the contradiction between《Montreal Protocol》and《Kyoto Protocol》list the thermodynamics parameters of the substitutive refrigerants,environmental characteristic parameters and assessment standard.It evaluates the substitntive refrigerants such as HCFC-123 and HCF-134a in the fields of environmental protection and application.
