摘要
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。
The paper presents a 60-hour unit performance test for the air-source heat pump heating system using the enhanced vapor injection technology in the severe cold region. This experiment uses the actual meteorological conditions as the experimental environment,using on-site test method. The experimental results show that when the average outdoor air temperature is-7. 5 °C,the units＇ average COP is 2. 01; When the environmental air temperature is-18 ° C,unit＇s COP is 1. 55 and the compressor exhaust temperature is 75. 1 °C; When the environment is-15 ° C,the average heating capacity of the unit is 36% of the nominal heat.During the test period,the average room temperature is 19. 56 ° C,which meets the winter heating requirements. The experimental results provide a reference for the application of air source heat pump in severe cold area.
