Method for cleaning air conditioner evaporator

Abstract

The invention relates to a method for cleaning air-conditioner evaporator, which uses refrigeration principle, through the combination of cooling, heating and ventilation functions, after fast refrigeration, the vapor in the air frosts or freezes on the surface of the evaporator quickly; then after fast heating, the frost or ice on the surface of the evaporator is heated and changes into water for removing the dust or other tiny miscellanies on the surface, and the evaporator is dried; after ventilation, the water in the evaporator is dried further. According to the invention, there is no need to add any components and cost based on the common air-conditioner, and there is no need to do manual intervention and dismounting of air-conditioner, as long as the air-conditioner operates according to the special process, the goal of the automatic cleaning evaporator is achieved.

Description

technical field [0001] The invention relates to a cleaning method for an air conditioner evaporator. Background technique [0002] The air conditioner in daily use is cooled by circulating air. Since the evaporator of the air conditioner uses a fan to exhaust the air and blow the heated or cooled air into the room, the evaporator is easily polluted by dust and other floating dust in the air during the air circulation process. At present, air-conditioning manufacturers only use filter screens to filter out impurities in the air, but cannot filter out very fine floating dust and bacteria suspended in the air. However, when the floating dust comes into contact with the moisture produced by the evaporator cooling, it will adhere to the surface of the evaporator. Over time, the evaporator of the air conditioner will be covered with a layer of dust, or even blocked, causing poor air circulation in the internal unit and insufficient evaporation. This leads to the following phenome...

AI Technical Summary

Problems solved by technology

[0003] 1 The energy efficiency ratio decreases, seriously affecting the cooling or heating effect;

[0004] 2 Increased power consumption: The power of the fan motor increases due to the increase of the load, and the compressor generates a large current due to the decrease of high and low pressure pressure. In serious cases, the indoor fan or outdoor compressor will be burned out, affecting the service life of the air conditioner;

[0005] 3 Small debris such as dust will cause mildew in the fins, and a variety of bacteria will multiply in a humid environment, which will have peculiar smell and affect the health of users

[0006] However, the traditional evaporator Qinghao needs to be disassembled and installed, which not only requires specialized technical maintenance personnel and professional cleaning tools, but also consumes a lot of manpower and material resources, high cost, and cleaning is not in place.

Ordinary users simply cannot clean the evaporator

[0007] Although the patent No. is 94220045.4 Chinese patent refrigerating and air-conditioning system condensed water recycling cleaning device, 200510025316.7 Chinese patent cleaning the method for the evaporator and axial fan blade of air-conditioning indoor unit, 200420094421.7 Chinese patent a kind of anti-clogging central air-conditioning evaporator also Air conditioner cleaning has been reported, but they require additional components, complicate the structure, affect the traditional air conditioner production process structure, and the cost is high, not economical and practical enough
