摘　　要：对郑州某办公楼的空气源热泵供暖系统进行了供暖性能实验,分析了室外气温和供暖负荷率对机组运行效果的影响,结果表明,寒冷地区冬季采用空气源热泵进行供暖具有技术可行性但并不经济。基于实验数据,对空气源热泵-太阳能组合系统进行了模拟研究,分析了不同供暖面积下,冷凝温度、蒸发温度、集热器面积及供水温度等对热泵供暖运行性能的影响,提出较为合理的匹配及运行方式。Carries out a heating experiment on an air-source heat pump（ASHP）system heating for an office building in Zhengzhou city.Analyses the influences of outdoor temperature and heating load ratio on operation performance.The results indicate that ASHP system is technologically but not economically feasible in cold area in winter.Based on the experimental data,simulates and studies the combined system of ASHP and solar collector.Analyses the effects of condensing temperature,evaporating temperature,collector area and supply water temperature on the heating performance of the system for different heating areas,and recommends more rational operating and matching modes.
