The method of claim 7, wherein the annual thermal management conditions include a cooling-in-summer-time/domestic-hot-water mode, a cooling-in-summer-extreme-heat/domestic-hot-water mode, a heating-in-winter/domestic-hot-water mode, and a single-domestic-hot-water mode in transition seasons; in the refrigeration and domestic hot water mode, the cooling/heat source tower does not work, the first heat pump circulation system and the second heat pump circulation system are both communicated with the direct heat recovery water tank, wherein the heat pump units of one group of heat pump circulation systems are used as a water chilling unit for refrigeration, so that cold energy is provided for the tail end of a refrigeration user, and the heat pump units of the other group of heat pump circulation systems are used as heating heat pumps for heating and domestic hot water is provided for the tail end of domestic hot water; the high-temperature cooling water returned to the direct heat recovery water tank by the water chiller serves as a heat source of a heating heat pump, and the low-temperature circulating water of the heating heat pump serves as a cold source of the water chiller;
in the modes of refrigeration, refrigeration and domestic hot water, the cooling/heat source tower is started, the first heat pump circulation system and the second circulation system are communicated with the cooling/heat source tower, and working media enter the direct heat recovery water tank through the cooling/heat source tower for circulation; the heat pump units of the first heat pump circulation system and the second heat pump circulation system are used as water chilling units for refrigeration, and the auxiliary heat source is started to supply water to the tail end of a domestic water user;
in a heating and domestic hot water mode, a cooling/heat source tower is started, a first heat pump circulation system and a second circulation system are communicated with the cooling/heat source tower, and working media enter a direct heat recovery water tank through the cooling/heat source tower for circulation; the heat pump units of the first heat pump circulation system and the second heat pump circulation system are used as heating heat pumps for heating the tail ends of heating users and supplying domestic hot water to the tail ends of domestic water users;
in the single life hot water mode, the cooling/heat source tower is turned on, and one of the first heat pump circulation system and the second circulation system is turned on and communicates with the cooling/heat source tower to supply heat to the raw water.
