The technical scheme adopted by the present invention to solve the technical problems existing in the known art is that a kind of soil source heat pump
The on-line monitoring method of the soil moisture in system is arranged temperature sensor I on ground heat exchanger water inlet main pipe, obtains buried
The inflow temperature T of heat exchange of heat pipe3, go out setting temperature sensor II on water conduit tube in ground heat exchanger, obtain underground pipe heat exchange
The leaving water temperature T of device4, go out in ground heat exchanger and flow sensor be set on water conduit tube, with obtaining heat pump system source circulation
The actual flow V of water pump1, using the flow V of industrial personal computer adjustably source water circulating pump1=V0, and counted in real time using following formula
Calculate soil moisture Tg:
Wherein: T0It, can be from soil thermal property test report acquisition for soil initial temperature；
