Embodiment 1

[0014] like figure 1 , the present embodiment provides an energy-saving system for building radiant cooling water circulation, which radiates cooling water to cold water around the clock without relying on sunlight. The whole system mainly includes: radiant refrigeration system 1 for cooling water, cold water circulation pipeline 2 for circulating cooling water, cold water temporary storage tank 3 for storing cooling water, and cold water utilization system for cooling the room 4. Auxiliary air conditioner 5 for auxiliary refrigeration, and a control system for controlling the cooling water circulation path, the radiant refrigeration system 1 communicates with the cold water circulation pipeline 2, and the cold water temporary storage tank 3 communicates with the cold water circulation pipeline 2 , the cold water utilization system 4 communicates with the cold water circulation pipeline 2 , and the auxiliary air conditioner 5 communicates with the cold water circulation pipeli...

Embodiment 2

[0018] This embodiment provides two kinds of materials used to replace the radiation cooling coating in Example 1, which are radiation cooling film and radiation cooling coating respectively. The choice of radiation cooling film and radiation cooling coating can be one of the two, or both. At the same time mixed use, this embodiment does not limit. Radiation cooling coating includes upper and lower two-layer structure, the upper layer: mainly composed of micron-sized spheres and polymer substrates, wherein the micron-sized spheres are clay, graphene, diatomaceous earth, SiS 2 , SiO 2 One or more of them, the polymer substrate can be one or more of PE, PP, PET, PS, PVC, PMMA, PVA, PET, TPX; the lower layer: mainly metal-plated reflective materials, such as Ag , Al and other materials. The lower structure is close to the roof radiant cooler, and water flows through the roof cooler. In this way, the heat of the water to be refrigerated is radiated into the atmospheric environme...

Embodiment 3

[0020] This embodiment provides a three-dimensional refrigerating sheet for replacing the carpet-type cold water coil in Embodiment 1. The three-dimensional refrigerating sheet is similar to a radiator and is directly installed in the indoor space. The water inlet end of the three-dimensional refrigerating plate is connected to the second end of the circulation pump 64 , and the water outlet end of the three-dimensional refrigerating plate is connected to the terminal of the cold water circulation pipeline 2 . Of course, this embodiment can also be a combination of carpet-type cold water coils and three-dimensional refrigeration fins, that is, both the carpet-type cold water coils and the three-dimensional refrigeration fins are located in the cold water circulation pipeline 2, and jointly cool down the room to strengthen Cooling effect.

[0021] In Examples 1, 2 and 3, the general refrigeration power is 60-120W / m 2 For example: when the roof area is 200m2, the average coolin...
