[0027] Specifically, a control valve a-1 is provided between the heat exchange medium outlet of the user end 8 and the heat exchange medium inlet of the domestic water heat exchange component on the roof of the building.

[0028] Furthermore, the domestic water heat exchange component on the roof of the building includes a domestic water reservoir 1, a heat exchanger 2 and a stop valve.

[0029] Furthermore, a first temperature control valve a-2 is provided between the heat exchange medium outlet end of the domestic water heat exchange component on the roof of the building and the heat exchange medium inlet end of the capillary network component on the roof of the building, and a second temperature control valve a-3 and a third temperature control valve c-1 are provided between the heat exchange medium outlet end of the domestic water heat exchange component on the roof of the building and the heat exchange medium inlet end of the user end 9.

[0030] Furthermore, the capillary network subassembly on the roof of the building includes a sunshade component and a capillary network 3.

[0031] Furthermore, a fourth temperature control valve b-1 and a first temperature controller b-6 are provided between the heat exchange medium outlet end of the capillary network assembly on the roof of the building and the heat exchange medium inlet end of the plate heat exchanger 4, a fifth temperature control valve c-2 is provided between the heat exchange medium outlet end of the plate heat exchanger 4 and the heat exchange medium inlet end of the user end 9, a sixth temperature control valve b-2 is provided between the heat exchange medium outlet end of the plate heat exchanger 4 and the heat exchange medium inlet end of the outdoor indirect evaporative cooling unit 5 of the building, a seventh temperature control valve b-3 is provided between the heat exchange medium outlet end of the plate heat exchanger 4 and the heat exchange medium inlet end of the mechanical refrigeration assembly 6 on the bottom floor of the building, and an eighth temperature control valve c-4 and a second temperature controller c-3 are provided between the heat exchange medium outlet end of the plate heat exchanger 4 and the heat exchange medium inlet end of the mechanical refrigeration assembly 6 on the bottom floor of the building.

[0033] Furthermore, a tenth temperature control valve b-5 is provided between the heat exchange medium outlet end of the outdoor indirect evaporative cooling unit 5 of the building and the heat exchange medium inlet end of the mechanical refrigeration component 6 on the bottom floor of the building.

[0034] Furthermore, the mechanical refrigeration component 6 on the ground floor of the building includes an evaporator 7 and a condenser 8 .

[0035] The main working process of a data center cooling system utilizing domestic water cooling provided by the present invention is: under the action of a pump, a high-temperature heat exchange medium flows from a user end 9 through a pipeline through a control valve a-1 and enters a heat exchanger 2 in a domestic water heat exchange assembly on the roof of the building. At this time, the heat exchange medium in the heat exchanger 2 exchanges heat with the domestic water and takes away the cooling energy in the domestic water.

[0036] Specifically, when the outdoor temperature is low, domestic water provides enough cooling capacity to reduce the temperature of the heat exchange medium to the temperature required by the user end 9. At this time, the second temperature control valve a-3 and the third temperature control valve c-1 are opened, the first temperature control valve a-2 is closed, and the heat exchange medium returns to the user end 9 through the return pipe for user use. If the cooling capacity provided by domestic water is not enough to reduce the temperature of the heat exchange medium to the temperature required by the user end 9, the second temperature control valve a-3 is closed, the first temperature control valve a-2 is opened, and the heat exchange medium flows into the capillary network subassembly on the roof of the building. Through the capillary network 3 and the air convection heat exchange, the temperature of the heat exchange medium is reduced again by using the natural cold source to reach the temperature required by the user end 9. At this time, the third temperature control valve c-1 is opened, the fourth temperature control valve b-1 is closed, and the heat exchange medium returns to the user end 9 through the return pipe for user use.

[0037] When the outdoor temperature rises, the temperature of the heat exchange medium after passing through the capillary network subassembly on the roof of the building has not yet dropped to the temperature required by the user end 9. At this time, the third temperature control valve c-1 is closed, the fourth temperature control valve b-1 is opened, and the heat exchange medium flows into the plate heat exchanger 4. Through the plate heat exchanger 4 and the building outdoor indirect evaporative cooling unit 5, the temperature of the heat exchange medium is further reduced to the temperature required by the user end 9. Then, the fifth temperature control valve c-2 is opened, the eighth temperature control valve c-4 is closed, and the heat exchange medium returns to the user end 9 through the return pipe for user use.

[0038] When the outdoor temperature is higher, the temperature of the heat exchange medium after passing through the plate heat exchanger 4 is still not reduced to the temperature required by the user end 9. At this time, the fifth temperature control valve c-2 is closed, the eighth temperature control valve c-4 is opened, and the heat exchange medium enters the mechanical refrigeration component 6 at the bottom of the building. Through the action of the mechanical refrigeration equipment, the temperature of the heat exchange medium is reduced to the temperature required by the user, and then returns to the user end 9.

[0039] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as limiting the present invention.
