摘要(Abstract)：
用于取代对臭氧层有破坏作用的制冷剂R22,国际上普遍认同的两种环保制冷剂为:410A和R407C。本文将分析R410A和R407C的特性,比较两者在传热性能、性能系数和蒸汽压力等方面的特征差异,为确定替代制冷剂的最佳选择提供技术支持。
R410A and R407C have been considered as two environmentally benign refrigerant candidates in the world for replacing the ODP refrigerant R22.The character of R410A and R407C was analyzed.for heat transfer, system performance, vapor pressure, and other characteristics was compared two candidates in details .The good guidance for optimizing refrigerant selection was provided.
