Beschreibung
Zusammenfassung:	The invention provides a cold and hot double-supply water source heat pump system and a control method, the system comprises a water source heat pump unit, the cold end of the water source heat pump unit is connected with a plate heat exchanger, the hot end of the water source heat pump unit is connected with a heat storage water tank, the plate heat exchanger is connected with an air compression equipment end, and the water temperature of the heat storage water tank is increased through heat generated by a heat pump to meet the heat supply requirement; meanwhile, the control mode of the heat pump unit is optimized, the situation that the temperature of outlet water at the cold end is too low due to too much cooling capacity and influences equipment is avoided, frequent starting and stopping when the temperature of the heat pump approaches the target temperature are also avoided, judgment on the energy efficiency condition of the heat pump unit is added in the control process, and it is guaranteed that the eq
