The technical field is as follows:

the invention relates to the field of water-cooled air conditioners, in particular to a cleaning control method for a water-cooled air conditioner unit.

Background art:

the water-cooled air conditioner is based on the natural physical phenomenon that water evaporation absorbs heat, and evaporation efficiency is affected by evaporation area, when a fan runs, negative pressure is generated in the cavity of the air conditioner, air outside the air enters the porous wet curtain surface and enters the cavity, the air is fully contacted with moisture, water on the wet curtain is evaporated, a large amount of damp heat is taken away, the temperature of the air passing through the wet curtain is reduced to be close to that of the wet bulb of the air outside the air, namely, the temperature of the dry bulb at the outlet of the air conditioner is 5-12 ℃ lower than that of the outdoor dry bulb, the temperature difference is larger and the cooling effect is better when the air is dry and hot, and meanwhile, the environment-friendly air conditioner utilizes evaporation to reduce the temperature far away, so the water-cooled air conditioner has the dual functions of cooling and humidifying.

The water storage bin and the wet curtain are two key parts in the water-cooled air conditioner, the main function of the water storage bin is to temporarily store enough water for the wet curtain to use, the main work of the wet curtain is to enlarge the contact area of water and air as much as possible, so that the evaporation of water is accelerated to exchange heat with outdoor air, cool air is generated and sent into a room, the water-cooled air conditioner is usually arranged on an outdoor window or a roof, the air blown out actually has peculiar smell or sundries, and the experience and the comfort of a user are seriously influenced. The reason is mainly that when the water-cooled air conditioner is not used for a long time, a large amount of dust, insects, leaves and other fine sundries are attached to the wet curtain paper, and a large amount of dust is also contained in the water storage bin, even dead water left over due to rain. When the water-cooled air conditioner is started, the parts are not cleaned effectively, so that the blown air contains foreign matters and peculiar smell. The wet curtain and the water storage bin need to be removed and then cleaned regularly, a large amount of manpower and material resources need to be consumed, and the maintenance is troublesome; simultaneously because present wet curtain adopts the corrugated structure, there is the evaporation capacity few, be not convenient for abluent defect, if set up a plurality of through-holes on wet curtain, can reduce the windage, accelerate the wind speed, thereby whole water-cooling air conditioning unit's evaporation efficiency has been improved, but the wet curtain that has a plurality of through-holes carries out abluent in-process with the water, the phenomenon of natural atrophy can appear, make the whole emergence of wet curtain structure warp, thereby influence the refrigeration effect in later stage, and it is difficult to clear away dust impurity etc. in the through-hole among the cleaning process.

The invention content is as follows:

the invention aims to overcome the defects and provide a cleaning control method of a water-cooling air conditioning unit, which can keep the cleanness of the system to the maximum extent, play the effects of cooling and humidifying to the maximum extent and ensure the air supply quality.
