Beschreibung
Zusammenfassung:	The invention discloses a ground-source solar heat pump heat supplying system for a greenhouse and a control method of the heat supplying system. The heat supplying system comprises a solar heat pump unit, a soil energy storing/taking unit, a ground-source heat pump unit, an indoor air conditioning unit and a control unit. The solar heat pump unit is connected with the soil energy storing/taking unit. The soil energy storing/taking unit is connected with the ground-source heat pump unit. The ground-source heat pump unit is connected with the indoor air conditioning unit. The control unit is connected with the solar heat pump unit, the soil energy storing/taking unit, the ground-source heat pump unit and the indoor air conditioning unit. The whole system runs in an energy storing mode, a heat supplying mode and a cooling mode through the control unit. By means of the mode, the heat supplying system integrates the solar heat collecting function, the soil energy storing function, the greenhouse heat supplying function and the refrigerating function, and dual control over the temperature of air and the temperature of soil in the greenhouse is achieved.
