Abstract

A GWHP (groundwater source heat pump) apparatus with superheated vapor heat recovery has been constructed in this paper. In the presetting working conditions (the inlet and the outlet temperature of the cooling water are respectively 18Â°C and 26Â°C, and the inlet and the outlet temperature of the chilled water are respectively 12Â°C and 7Â°C), the effects of the domestic hot water flow on the heating time of the domestic hot water and the heat recovery amount have been studied, and the features of the condensation heat amount and the heat recovery amount have been analyzed. The research results show that the best match of the domestic hot water flow and the heating time must be considered and the presetting temperature of the water tank must be reasonably determined.
