Description

Technical Field

[0001] The utility model relates to the technical field of central air-conditioning cooling systems, in particular to a central air-conditioning energy-saving cooling system. Background Art

[0002] The central air-conditioning system consists of one or more cold and heat source systems and multiple air conditioning systems. It uses the principle of liquid vaporization refrigeration to provide the required cooling capacity for the air conditioning system to offset the heat load of the indoor environment; the heating system provides the required heat for the air conditioning system to offset the cooling and heating loads of the indoor environment. During the use of central air conditioning, water cooling is required for cooling, and the cooling water is circulated for use.

[0003] Chinese patent publication number CN220119894U discloses an energy-saving cooling tower for central air conditioning. Hot water enters the serpentine water pipe through the inlet end, and the upper heat exchange water outlet component sprays cooling water into the cooling filler of the loading tank, so that the cooling filler accelerates the cooling of the hot water in the serpentine water pipe buried therein. The lower heat exchange water receiving component continuously inputs cooling water to the upper heat exchange water outlet component to form a cooling water circulation water circuit, thereby continuously keeping the cooling filler in a low temperature state, and more effectively exchanging heat with the hot water in the serpentine water pipe.

[0004] However, compared with the existing technology and comparative documents, during the use of the existing central air-conditioning energy-saving cooling system, the central air-conditioning circulating water enters the cooling tower for water spraying and cooling, and the cooled circulating water flows out to continue cooling the central air-conditioning, while the cooling water enters the tower body for return water utilization. However, during recycling, the temperature inside the tower body is high and the cooling water temperature drops slowly, resulting in the cooling water temperature being too high. At this time, a large amount of new external cooling water is required to neutralize and cool the high-temperature cooling water, thereby increasing the use of cooling water and having a poor energy-saving effect. Utility Model Content

[0013] Preferably, both sides of the pipe rack are connected with fixing frames, and the fixing frames are installed on the inner side wall of the machine body.

The protective net 7 can prevent external impurities from entering the cooling box 601, and the protective net 7 is a plate-shaped structure on the side of the pump 602.

[0024] like Figure 1-Figure 3 As shown, the water inlet and outlet of the pipe rack 2 are both located outside the body 1, making it convenient for the pipe rack 2 to be connected to the circulating cooling pipe of the external central air conditioner.

[0025] like Figure 1-Figure 3 As shown, the cooling assembly 3 includes a diverter frame 301, a nozzle 302 and a connecting pipe 303, and the nozzle 302 is threadedly connected to the diverter frame 301, so that the cooling water is easily diverted through the diverter frame 301 and sprayed from the nozzle 302 to the pipe rack 2.

[0026] like Figure 1-Figure 3 As shown, the connecting pipe 303 is connected to the pipe clamp of the diverter rack 301 , and the connecting pipe 303 is located outside the body 1 , so that the external cooling pipeline is connected to the diverter rack 301 through the connecting pipe 303 .

[0027] like Figure 1-Figure 3 As shown, air intake nets 8 are installed on the lower wall of the body 1. The air intake nets 8 are louver structures, which facilitate external air to enter the body 1 through the air intake nets 8.

[0028] like Figure 1-Figure 3 As shown, an exhaust fan 9 is installed at the top of the body 1, and a motor 10 is connected to the top of the exhaust fan 9, so that the motor 10 can drive the exhaust fan 9 to rotate, and the high-temperature gas in the body 1 is extracted through the exhaust fan 9.
