| Abstract: | Experimental research on the stability of thermostatic expansion valve(TEV)in the system of small-sized air source heat pump water heater(ASHPWH)was carried out in this paper. The stability of TEV in the ASHPWH system is analyzed.Some advices are raised to obtain stable operation.The refrigerant charging is another important factor which influences the performance of the system.It is pointed out that a good command of both the opening of the TEV and the refrigerant charging can lead the system to the best operation. |
