热泵空调中R407C中间注液循环冷却系统与单级压缩循环系统的性能比较

Comparison of Performance of Medial Liquid In jection Circulating Cooling System with Single Stage Compression Circulating System on Heat-pump Air Conditioner by Use of R407C

简单介绍了 R2 2的替代工质 R4 0 7C的特点和中间注液冷却循环系统 ,分析比较了在热泵空调装置中 R4 0 7C中间注液循环冷却系统与单级压缩循环系统在制冷和制热时的性能系数 ,得出注液系统在降低压缩终温 ,提高容积效率的同时 ,可明显提高制热性能。

This paper introduces simply the characteristics of 407C (R22's substitute working medium) and medial liquid injection circulating cooling system.The refrigerating cofficient of performance and heat making cofficient of performance of 407Cs medial liquid injection circnlating cooling system with single stage compression circulating system are compared and analysised on the heat-pump air conditioner. The result shows that medial liquid injection circulating cooling system can put down compressor-discharge temperature and enhance volumetric efficiency, heat making performance and be obviously increased together.
