A seasonal switching valve 7 19 is also installed between the multiple heat source towers 1 and the two heat pump condensers 5. This valve is also used to adjust the system's operating conditions according to the seasons.

[0026] The other ends of the two heat pump-side water pumps 4 are fixedly connected to two heat pump air conditioning-side water pumps 9. These pumps are responsible for transporting heated water from the heat pump condensers to the air conditioning water collector 11 for heat exchange. A seasonal switching valve 13 is installed between the two heat pump condensers 5 and the heat pump air conditioning-side water pumps 9. This valve is used to adjust the system operating conditions according to the seasons.

[0027] The other ends of the two heat pump air conditioning water pumps 9 are fixedly connected to an air conditioning manifold 11, which collects and distributes heated water. The other end of this manifold 11 is fixedly connected to two evaporation-side water pumps 10, which transport the heated water from the manifold to the chiller evaporator 8 for heat exchange. The other ends of the two evaporation-side water pumps 10 are fixedly connected to two chiller evaporators 8, which transfer heat from the refrigerant to the heated water.

[0028] The other end of the chiller evaporator 8 is fixedly connected to an air conditioning water distributor 12, which distributes heated water to various rooms or areas. A third seasonal switching valve 15 is located between the air conditioning water distributor 12 and the two heat pump condensers 5.

A fourth seasonal switching valve 16 is installed between the air conditioning water distributor 12 and the heat pump evaporator 6. This valve is also used to adjust the system's operating conditions according to the seasons.

This valve is also used to adjust the system's operating conditions according to the seasons. The other end of the air conditioning water distributor 12 is fixedly connected to the two heat pump condensers 5.

[0030] Working Principle: During summer switching operation, the chiller's evaporator 8, air conditioner water distributor 12, evaporation-side water pump 10, air conditioner water collector 11, chiller condenser 7, seasonal switching valve 9 21, heat source tower 1, water collection tray 2, condensation-side water pump 3, and seasonal switching valve 10 22 all operate. In the heat source tower, the heat pump evaporator 6, seasonal switching valve 4 16, seasonal switching valve 2 14, heat pump air conditioner-side water pump 9, heat pump condenser 5, seasonal switching valve 7 19, heat pump-side water pump 4, and seasonal switching valve 5 17 all operate. Seasonal switching valve 1 13, seasonal switching valve 3 15, seasonal switching valve 6 18, and seasonal switching valve 8 20 are all closed, indicating that multiple chillers are operating and providing cooling, and the medium in the pipes is water.

[0031] During winter switching operation, the heat pump evaporator 6 in heat source tower 1, seasonal switching valve eight 20, heat source tower 1, water collection tray 2, heat pump side water pump 4, and seasonal switching valve six 18 are all in operation. The heat pump condenser 5, seasonal switching valve three 15, air conditioner water distributor 12, air conditioner water collector 11, heat pump air conditioner side water pump 9, and seasonal switching valve one 13 are all in operation.

Heat is supplied solely by the heat source tower heat pump, and the medium in the pipes is now a salt solution.

[0032] Thus, the heat source tower 1 is used as a cooling tower in summer to release heat into the air, and absorbs heat from the air in winter and converts the absorbed heat into high-grade heat in the form of a heat pump to meet the heating demand.
