| description | The invention provides a soil source heat pump and cooling tower composite system. The soil source heat pump and cooling tower composite system sequentially comprises a buried pipe, a heat pump unit, a fan coil, a water chilling unit and a cooling tower according to the pipeline circulation sequence. The system further comprises a controller. According to the soil source heat pump and cooling tower compound system and the optimal control method thereof, a refrigerating unit is introduced to serve as an auxiliary cold source, the cooling tower serves as an auxiliary heat dissipation source, the buried pipe and the heat pump unit can operate intermittently, and soil temperature recovery is facilitated; through annual simulation of the system, the start-stop temperature of the cooling tower is set, the soil temperature interval of efficient operation of the heat pump unit is determined, it is guaranteed that the cooling tower and the heat pump unit always operate efficiently, and the operation energy efficiency |
