摘要: 环保替代制冷剂已大面积推广,同时空调器在一些特殊工况运行环境愈发恶劣,能在高温工况下高效稳定运行的空调器需求日渐增加。通过对三种不同的替代工质R410A、R32、R290的高温热物性进行对比,并在同配置分体房间空调器制冷系统上,分别充注R410A、R32、R290工质在焓差室进行60℃以上高温制冷能力测试。结果表明,在高温工况下,R290相对于R32以及R410A,在能力及能效体现上有极大的优势,排气温度低,系统可靠性强,在中高温恶劣工况下有着良好的应用前景。

Abstract: Environmental protection alternative refrigerant has been widely promoted, at the same time, the operating environment of the air conditioner is getting worse under some special working conditions ,the demand of air conditioner which can operate efficiently under high temperature condition is increasing day by day. Three alternative refrigerants R410A, R32 and R290 are compared in high temperature physical properties, and in the same configuration of split room air conditioner refrigeration system, R410A, R32 and R290 are respectively charged to test the high temperature refrigeration capacity above 60℃ in the air-enthalpy test room. The results show that R290 is superior to R32 and R410A in capacity and energy efficiency at high temperature, the exhaust temperature is low and the system is reliable. It has a good application prospect in the middle and high temperature area.
