碳氢化合物R1270替代R502的性能分析

Refrigeration Performances Analysis on Substitute R1270 for Hydrocarbn R502

比较了R502和几种碳氢化合物的饱和蒸气压曲线,结果表明R1270的热物理特性与R502相似。通过R1270与R502的循环性能比较,发现R1270具有制冷量大、COP高的优点。若不考虑可燃性,R1270可考虑作为R502的优良替代制冷剂。

This paper compares the physical characteristics of R502 and some hydrocarbons of interest asrefrigerants, the results indicate that R1270 is a favorable alternative for R502. In addition, the performances of R502and R1270 in terms of different thermodynamic cycles are compared, the general conclusion is that the COP and q0 ofR1270 is higher than R502’s. So , the hydrocarbon refrigerant R1270 seems to be an appropriate candidate to replaceR502 if its flammability were ignored.
