摘　　要：基于郑州市典型气象,对空气源热泵辅助加热太阳能热水系统试验,利用热经济学方法对该系统进行了分析,结果表明在电价为0.56元/kWh时,系统的输出用成本随辐射量减少而增加,输出用成本为0.3～0.7元/kWh,平均值为0.46元/kWh,明显低于电价,具有经济可行性.同时对影响平均输出用成本的因素进行了敏感性分析,认为太阳辐射量是最主要的因素,其次为环境温度,空气源热泵辅助加热太阳能热水系统初投资费用的影响最小.In the paper,a test is done for solar energy water heating system in conjunction with air source heat pump（SEWHSASHP） on the base of typical weather of Zhengzhou city.The system is analyzed by using thermal economy,and the results showed that exergy cost of the system increases with the decrease in solar radiation when electricity price is 0.56 yuan/kWh.Exergy cost of the system is from 0.3 to 0.7 Yuan/kWh with average cost 0.46 Yuan/kWh,which is lower than electricity price with economical feasibility.The influence factors of the average exergy cost are given sensitivity analysis,and solar radiation is the main influence factor,ambient temperature is the second factor,initial investment of SEWHSASHP makes small influence on average exergy cost.
