Simulation Study on Geothermal Direct Supply Combined with Water Source Heat Pump

This paper uses heat pump technology to study a novel thermal energy efficient utilization system for geothermal water.It is a comprehensive utilization of heating system that high temperature geothermal water directly supplies heat stage by stage with combining two-stage water source heat pumps.Results indicate that the temperature of discharged water is below 5 o C after the novel system taking advantage of heat energy deeply, which achieves the maximum utilization for geothermal water.
