Energy saving analysis of ground-source heat pump and air-source heat pump in Shanghai area

Compares the energy saving performance of ground-source heat pump and air-source heat pump from the aspect of thermodynamics. Brings forward some suggestions for the application of ground-source heat pump in Shanghai area that the temperature of water from the ground heat exchanger should be less than 30 ℃ in summer and higher than 10 ℃ in winter.
