| Abstract: | The working principles of the direct expansion solar assisted heat pump water heater(DX-SAHPWH)were introduced. A mathematical model for the DX-SAHPWH system was established by steady and concentrating method in the whole unit.To prove the liability of the models,experiments were carried out and data were calculated for typical climates. The differences between experimental and simulated values is quite small.Variable frequency operation control strategy in variable climates was thus obtained according to t... |
