Designs a groundwater source heat pump (GWHP) experimental apparatus with superheated vapor heat recovery. For the setting working condition (the inlet and the outlet temperatures of the cooling water are 18 ℃ and 26 ℃respectively, the inlet and the outlet temperatures of the chilled water are 12 ℃ and 7 ℃ respectively, and the domestic hot water flow rate is 750 L/h), studies the effects of the superheated vapor heat recovery apparatus on the suction and discharge temperature of the compressor, the evaporation temperature and the condensation temperature. The results show that compared with the GWHP without superheated vapor heat recovery, this system has better operating stability and the operating condition has been further improved.
