AI Technical Summary
During shutdown, the water circulation pipes of water-cooled air conditioners are damaged by oxidation due to the combination of residual water and oxygen. Existing maintenance methods rely on manual operation, which is time-consuming, labor-intensive, and easily overlooked, resulting in a shortened equipment lifespan.
The target injection volume of the film-forming anti-corrosion liquid is accurately determined based on the total water volume of the water circulation pipeline, and the fluid drive pump is driven to run, so that the film-forming anti-corrosion liquid is fully mixed with the circulating water to form a hydrophobic protective film; the residual liquid is automatically drained in response to the air conditioner start command, realizing fully automated maintenance.
It effectively inhibits electrochemical corrosion, ensures pipeline protection during water chiller and air conditioner shutdowns, achieves automated maintenance, avoids the shortcomings of manual operation, and improves equipment lifespan.
