| Abstract: | 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 ... |
| Keywords: | air source heat pump solar energy water heating system thermal economy exergy cost |
