Therefore, they cannot be understood as limitations on the present invention.

[0017] Reference Figure 1 A central air-conditioning condensate water recycling system includes a plurality of air-conditioning components 1 and a water collector 2 connected to the air-conditioning components through water pipes and used to collect condensate water.

[0018] The water collector 2 is connected to a water filter device 4 via a pipe 3. In order to effectively control whether water flows in the pipe 3, an electric three-way valve for controlling the switch is provided on the pipe 3. A drain pipe 18 is also externally connected to the left end of the electric three-way valve. The upper and lower ends of the electric three-way valve are normally open, and the left end is normally closed. In special circumstances, the lower port can be closed and the left port and the pipe can be opened for drainage.

[0019] In order to further improve the quality of water, reduce viruses and improve water quality, the water filtration device 4 is connected to a disinfection device 5; it needs to be able to filter impurities in the condensed water, eliminate microorganisms in the water, ensure that the water quality meets national standards, and ensure that the condensed water does not produce precipitation and microbial communities in the water tank or water tank; and it cannot generate heat or generate too much heat, and the low temperature characteristics of the condensed water must be guaranteed.

[0020] The disinfection device 5 is connected to an electric three-way valve 6 through a pipeline, one end of the electric three-way valve 6 is connected to a first water storage tank 7, a water replenishing device 9 is provided on the top of the first water storage tank 7, and an electric two-way valve for controlling the switch is provided on the water replenishing device 9, the first water storage tank 7 is also connected to a water outlet pipe 10, and a water pump 11 is provided on the water outlet pipe 10, and the other end of the water outlet pipe 10 is connected to a cooling tower, and the water pump 11 can send the condensed water in the first water storage tank to the cooling tower through the water outlet pipe to replenish the cooling water;

[0021] The other end of the electric three-way valve 6 is connected to a second water tank 8, which is connected to a water reservoir 12 via a pipeline 14. A second water pump 13 is provided on the pipeline, and an electric two-way valve is also provided on the rear side of the second water pump 13.

[0022] The pipeline 14 is externally connected to a first external pipe 15, the head of the first external pipe 15 is connected to the front end of the second water pump 13, and the tail of the first external pipe 15 is connected to the end of the pipeline 14; and an electric two-way valve is provided on the first external pipe 15. When the second water pump is closed or the amount of condensed water is greater than the flow rate of the second water pump, the condensed water enters the water tank through the bypass pipe.

[0023] The top of the water tank 12 is externally connected to an overflow pipe 121, which is connected to the drainage system. The bottom of the water tank 12 is externally connected to an outlet pipe 122, which is used to connect to external domestic water, sanitary water, greening water and other equipment that adapts to the water quality of condensed water, and the water consumption must be controlled within the range allowed by the water tank;

[0024] The pipeline 14 is further externally connected to a second external pipe 141, with the head end of the second external pipe 141 being placed after the second water pump, and the tail end being placed after the electric two-way valve and at the front end of the tail end of the first external pipe. A third external pipe 142 is connected to the second external pipe 141, and a second water heat exchanger 16 and an electric two-way valve are provided on the second external pipe 141, and a first water heat exchanger 17 and an electric two-way valve are provided on the third external pipe 142.

[0025] The opening and closing of the right and lower channels of the electric three-way valve, as well as the degree of opening, are determined based on the system's water usage. If condensate is insufficient, the right channel is prioritized, while the lower channel is closed. This is because condensate flows through the right channel into the cooling water storage tank. The first storage tank (7) is equipped with a tap water supply pipe, allowing for tap water replenishment. The second storage tank lacks a supply pipe because the cooling tower's water supply temperature requirement is not as high as that of the water heat exchanger. Therefore, if condensate is insufficient, disinfected tap water can be used.

[0026] If condensed water is continuously generated and there is excess water at the end of the water use, the excess water should be allowed to flow naturally into the water storage tank and discharged from the overflow pipe. This is the only way to ensure that the condensed water stored in the water tank is in a flowing state, thereby ensuring the low temperature characteristics of the condensed water in the water tank. If the water end is not used for a long time, it can be directly discharged from the pipeline using a three-way valve;

[0027] In this implementation, air conditioning units 1, 2, 3, ..., and n generate condensate during the dehumidification season. This condensate from each unit is collected in a condensate pan through condensate piping and then collected in a manifold. A filter screen should be installed at the outlet of the condensate pan to prevent particulate matter from entering the collection pipe. The manifold outlet is connected to an electric three-way valve, the lower outlet of which is connected to a filter and disinfection device to filter and disinfect the condensate.

[0028] The treated condensed water is divided into two paths at the three-way valve. The first path enters the first water tank through the right pipe. A tap water replenishing device is provided on the top of the first water tank. The water pump can send the condensed water in the first water tank through the pipe to the cooling tower to replenish the cooling water.

[0029] The second route enters the second water storage tank through the lower pipeline. The condensed water in the second water storage tank can be sent to the end of the water heat exchanger through a water pump. It can also enter the water storage tank through the bypass pipe where the two-way valve is located without passing through a water pump. The condensed water stored in the water storage tank can be sent to the water use end through a water pump. Through the above methods, the collection and utilization of condensed water can be realized.

[0030] The benefits of the present invention are that the present technical solution collects condensed water from air-conditioning components through pipelines, collects and utilizes the condensed water from the air-conditioning, saves water resources and recycles the energy in the condensed water, reduces environmental pollution, saves water resources and alleviates the problem of water shortage.

[0031] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
