Abstract :
A GWHP (groundwater source heat pump) experimental 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 18°C and 26°C, and the inlet and the outlet temperature of the chilled water are respectively 12°C and 7°C), the effects of the superheated vapor heat recovery system on the suction and discharge temperature of the compressor, the evaporation temperature and the condensation temperature have been studied. The research results show that compared with the GWHP without superheated vapor heat recovery, the GWHP with superheated vapor heat recovery system has better operating stability, and the operating condition has been further improved.
