新型制冷剂R1234yf的性能分析

摘要

The current requirements for selecting refrigerants was introduced firstly, and then the new type refrigerant, R1234yf, was compared with existing refrigerants of R32, R22 and R717 from the aspects of thermal physical properties, material compatibility, oil solubility and thermal performance. The prospects for the development of new refrigerants in emission reduction, safety, energy conservation requirements were discussed.%　　本文先介绍目前对制冷剂选择的要求，然后从热物理性质、材料兼容性、溶油性、热工性能等几个方面，比较新型制冷剂R1234yf与R32、R22及R717的优劣，讨论新型制冷剂在减排、安全、节能要求下发展前景。
