Study on Heat Balance of Coupling Operation of Solar-Earth Source Heat Pump
To further improve the full-season operation effect of the earth-source heat pump in Northern China,this paper designs a coupling system of solar energy and earth-source heat pump that starts and stops with temperature control to realize the timely heat exchange and concurrent heating of the solar water storage tank.Setting monitoring wells,the full-cycle soil temperature is measured by the heat response test.The test data showed that the designed system can effectively solve the problem that the shallow soil temperature of the soil source heat pump system in cold regions decreases annually,and the shallow soil temperature reaches heat balance when the solar collector collecting area and heating floor area ratio is 1∶14,realizing the stable and reliable operation,high energy efficient,and low operation cost of the heating and cooling system.This paper is of reference significance for the promotion and application of the earth-source heat pump in cold regions in Northern China.
