论文以严寒地区应用的喷气增焓技术空气源热泵供暖系统为研究对象,以实际气象条件为实验环境,采用现场在线测试方法,进行为期60 h机组性能测试,实验结果表明:室外环境空气平均温度为-7.5°C时,机组平均COP为2.01;环境空气温度为-18°C时,机组的COP为1.55,压缩机排气温度为75.1°C;环境空气温度为-15°C时,机组平均制热量衰减为名义制热量的36%。测试期间典型房间的平均温度为19.56°C,满足冬季供暖需求。实验结果为空气源热泵在严寒地区的应用适宜性提供了参考。
In this paper, the air-source heat pump heating system using air enthalpy increase technology in harsh area is taken as the research object. The real-time meteorological conditions are used as the experimental environment and the on-site test method is used to test the performance of the air-source heat pump system for 60 h. The experimental results show that the average ambient air temperature -7.5 ° C, the average COP of the unit is 2.01; when the ambient air temperature is -18 ° C, the COP of the unit is 1.55 and the compressor discharge temperature is 75.1 ° C; when the ambient air temperature is -15 ° C, the unit The average heat loss is 36% of nominal heating. The average temperature of a typical room during the test is 19.56 ° C to meet the winter heating needs. The experimental results provide references for the applicability of air source heat pumps in cold regions.
