Paper Title:
Theoretic Study on a Direct-Expanded Ground-Source Heat Pump
  Abstract

A distributed parameter method has been established for a ground-source heat pump in this paper, with this model, the working process of this heat pump system was simulated. The results agree well with experimental data and show that heat-capacity and COP increase when the cooling water flow rate in the tube-in-tube heat exchanger increases; heat-capacity decreases when the temperature of inlet water of the tube-in-tube heat exchanger rises; COP, between 3.8 and 4.5, is higher than that of conventional air-source heat pumps.
