| 摘 要： | 最近几年HFO类新型制冷剂、R32以及二者组成的混合物因其较低的温室效应系数逐渐为行业所重视。本文对比了R410A及其潜在替代物R32、R447A三种制冷剂在不同转速、不同室外温度下的房间空调器系统的运行特性,发现与R410A相比,R32和R447A均具有更高的能效;相同压缩机排量下,R32具有较高的制冷能力及排气温度,而R447A在高温工况以及高转速下具有一定优势。

| Abstract: | New HFO refrigerants, R32 and their mixtures have been developed and interested by air conditioner industries for their low GWP. In this paper, R410A was chosen to compare the performance with its potential replacements R32 and R447A. The RAC capacity, energy efficiency and discharge temperature were tested while changing the compressor speed, outdoor temperature. It was found that both R32 and R447A had better efficiency than R410A. Moreover, R32 has largest cooling capacity and also highest discharge temperature, and R447A had potential advantages for high ambient temperatures and high compressor speed conditions. |
