After the air conditioner is used for a long time, a large amount of dust and dirt will accumulate in the filter, evaporator and air supply system, resulting in a large number of bacteria and viruses. These harmful substances circulate indoors with the air, polluting the air, spreading diseases and seriously endangering human health. Moreover, dirt will reduce the refrigeration efficiency of air conditioners, increase energy consumption and shorten the service life of air conditioners. Therefore, the air conditioner must be cleaned after a period of use or when it is turned off in different seasons. Only in this way can you have a good, comfortable and safe air environment. Because of the special structure of evaporator and condenser, blowing with compressed gas or cleaning with detergent is often ineffective. The company adopts special air-conditioning cleaning agent, which can quickly, thoroughly and safely remove all kinds of dust and bacteria from condensers and evaporators and achieve ideal results. According to the air conditioning maintenance manual, air conditioners are generally cleaned once a year before use in summer or after use in autumn. During the operation of the air conditioner, it is necessary to keep the internal electrostatic dust collection and the exchange of air flow and heat with the outside, so the dust in the environment is very easy to enter the evaporator of the indoor unit of the air conditioner. Being outdoors for a long time will be blocked by dust. Among all household appliances, air conditioning is the most serious dust pollution. Because of the special structure of evaporator and condenser, blowing with compressed gas or cleaning with detergent is often ineffective. The company adopts special air-conditioning cleaning agent, which can quickly, thoroughly and safely remove all kinds of dust and bacteria from condensers and evaporators and achieve ideal results. At present, almost all air-conditioning maintenance departments simply clean the filter screen, but not the condenser and evaporator, which is precisely the part where air-conditioning dust is the most serious and harmful to human health.
