[0013] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.
[0014] The utility model discloses a water-cooled air conditioning coil external circulation cleaning system, comprising a water-cooled air conditioner 1, a cooling tower 3 and an external circulation cleaning water bucket 8. An air conditioning coil 2 is arranged inside the water-cooled air conditioner 1; one side of the air conditioning coil 2 is connected to the cooling tower 3 through a pipeline provided with an air conditioning inlet valve 5 and an air conditioning outlet valve 6 respectively, and the pipeline provided with the air conditioning inlet valve 5 is also provided with an air conditioning water circulation pump 4; the air conditioning water inlet and sewage outlet 7 and the air conditioning water outlet and sewage outlet 10 on the other side of the air conditioning coil 2 are respectively connected to the external circulation cleaning water bucket 8 through separate pipelines, and the pipeline connected to the air conditioning water outlet and sewage outlet 10 is also provided with an external cleaning circulation pump 9. Among them, the number of the air conditioning water circulation pumps 4 is 2, and the two air conditioning water circulation pumps 4 are connected in parallel.

[0015] Working principle: When the air conditioning circulating water pump is turned on, the air conditioning inlet valve and outlet valve are both in the open state. The air conditioning circulating water pump pumps the clean water cooled by the cooling water tower into the water-cooled air conditioner, and heat is exchanged through the air conditioning coil of the water-cooled air conditioner. The clean water with heat then flows back to the cooling water tower for cooling, thus forming a cycle.
[0016] Water-cooled air conditioner coil external circulation cleaning process: 1. Stop the water-cooled air conditioner and turn off the air conditioner circulation water pump. 2. Close the water-cooled air conditioner inlet valve and outlet valve. 3. Remove the air conditioner water inlet and outlet plugs. 4. Connect the external circulation water pump water pipe to the water-cooled air conditioner outlet, and connect the air conditioner water inlet to the external circulation cleaning bucket. 5. Add about 0.5m3 of water to the external circulation cleaning bucket. 3Clean water and add 25KG citric acid monohydrate (the air conditioning coil is mainly blocked by alkaline impurities, and citric acid solution can effectively dissolve alkaline impurities). 6. Turn on the external cleaning circulation pump. 7. Turn on the water-cooled air conditioner, heat the cleaning circulating water, heat the circulating water to about 60°C, and turn off the water-cooled air conditioner to effectively improve the cleaning efficiency. 7. Clean for about 5 hours (depending on the degree of blockage of the air conditioner, the cleaning time can be appropriately extended or shortened), and turn off the circulating water pump. 8. Remove the external circulation cleaning system. 9. Open the air conditioning inlet valve, and use the cooling tower pipeline to clean and discharge the residual cleaning sewage in the air conditioner until the clean water is discharged, close the air conditioning inlet valve, and reinstall the air conditioning inlet and outlet plugs. 10. Open the air conditioning inlet and outlet valves and start the circulating water pump. 11. Turn on the water-cooled air conditioner and the cleaning is completed.
