A practical indirect expansion solar-air source heat pump water heater (IESASHPWH) is tested for its fundamental performances and analyzed for its annual practical performances. Then three performance optimization schemes are designed
analyzed for their feasibilities and tested for the effects several times under the winter condition. Eventually an operation strategy integrated with all the three optimization schemes is proposed and simulated under annual climate conditions. The result shows that the compound system can reduce annual power consumption by 45.8%.
