摘要
提出了一种适用于90-110℃冷凝温度范围的HFC类中高温热泵非共沸混合工质,其理论循环性能优于CFC114,实测COP为纯工质HFC245fa的97.2%-130.6%、制热量高于HFC245fa。
A new non-azeotropic mixture has been proposed as the working fluid for moderate and high temperature heat pump applications at the condensing temperature range of 90℃-110℃ based on theoretical analysis and experimental investigations. The mixture has greater heat capacities than HFC245fa; and its experimental COPs are 97.2 %-130.6% of HFC245fa＇s values.
