With the development of economy, more and more families are equipped with air conditioners. We may have more air conditioners and less cleaning. Many friends don't know how to clean the air conditioners. If we don't clean the air conditioners for a long time, the air conditioners are easy to get old and fail. But the cleaning of air conditioners is not simple, so we should learn how to clean them How to clean the air conditioner.
In addition to cleaning professionals to do air conditioning cleaning, in fact, we can also learn some of the correct methods of air conditioning cleaning, try to clean the air conditioning at home, let's see the introduction below.
The air conditioner must be thoroughly cleaned and disinfected after using for a period of time or when the air conditioner is shut down in season. This can not only ensure the healthy and fresh air-conditioning environment, but also extend the service life of air-conditioning and improve the efficiency of air-conditioning. However, due to the different styles and brands of air conditioners, the cleaning methods are also different. Therefore, cleaning and disinfection should be carried out in strict accordance with the product instructions. Of course, can invite professional and technical personnel, the use of special equipment and special air conditioning cleaning agent is the best.
Air conditioning cleaning time
According to the different location of the air conditioner, the cleaning cycle of the air conditioner will also be different. In general, in the household use, it can be cleaned once every three months, while in the office, it should be cleaned once a month. If it is used in places with high dust content such as clothing factories, the cleaning frequency should be more frequent. Because the filter screen of household air conditioner is easy to disassemble, when to clean, just observe through the grille and see that there is obvious dust in the filter screen, then you can clean it. At the same time, the cleaning of heat sink is the key.
Because there is a lot of dust left there, you have to use a professional cleaning agent. Moreover, the cleaning agent of indoor unit is different from that of outdoor unit. Indoor unit is mainly used for cleaning and sterilization, while outdoor unit is for dust removal and degreasing. I feel that the cooling effect of the air conditioner is getting worse and the air volume is getting smaller. This is also a signal that it should be cleaned long ago. The correct cleaning of air conditioning in different seasons can not only ensure the health and freshness of air conditioning environment, but also prolong the service life of air conditioning and improve the efficiency of air conditioning.
Cleaning of shell and filter screen
When cleaning, first wipe the air conditioning shell with a cloth, then open the shell, remove the filter screen, brush most of the dirt attached to the filter screen with a clean filter brush, then put the filter screen into warm water for a while, finally flush the filter screen with flowing tap water for several times, dry it with clean cloth, and then install the cleaned filter screen back into the air conditioner Inside, just close the air conditioner shell.
Pay attention to the water temperature should not exceed 50 ℃, it is best not to use washing powder, detergent, gasoline, banana water, etc., to avoid deformation of the filter screen; in addition, do not use sponge cleaning, because it will damage the surface of the filter screen.
Cleaning of evaporator
The evaporator is also known as the cold and heat exchanger. When the air conditioner is working, the evaporator will take away the hot air in the room and send the cold air into it at the same time. Although the evaporator is protected by a filter screen, 80% of the dust will pass through the filter and adhere to the wet evaporator. These places are easy to breed bacteria and mites, and affect the normal work of air conditioning, so they are the parts that need to be cleaned.
At present, there is a special evaporator cleaning agent on the market. When using, shake the cleaning agent evenly and spray it on the air inlet surface of the air conditioner evaporator. If there is too much dirt, it can be wiped off with a wet cloth and washed with a small amount of water. However, it should be noted that the evaporator must be dried after cleaning.
Cleaning of condenser
Generally, the external machine does not need to be disassembled for cleaning, which is easy to cause mechanical failure and fluorine leakage. The fin shaped aluminum foil heat sink of outdoor unit can be directly washed up and down with water pipe, or cleaned up and down with long hair brush. The condenser is installed between the exhaust port of the compressor and the electronic expansion valve.
The high-temperature and high-pressure gas discharged from the air-conditioning compressor enters the condenser and is cooled by copper tube and aluminum foil. If dirt is accumulated here, it will affect the normal operation of freon and various components. At present, there are special condenser cleaning agents on the market, which can be used directly after purchase. Of course, the condenser can also be directly rinsed with water pipe, or cleaned up and down with a long brush.
Cleaning of air outlet and roller
Idle air conditioning is easy to gather dirt on the air outlet and roller, and sometimes even block the air outlet. Especially, there are many grooves and gaps on the roller. If the air conditioner is blocked, the air outlet will be affected and mold will easily grow. To clean these two places, you must brush them carefully with a brush. At present, there are professional transparent air-conditioning cleaning covers on the market. After the cover is covered, it can be simply and thoroughly cleaned by washing with high-pressure water gun.
Cleaning and disinfection of air conditioner radiator
Many people mistakenly think that the pollution of air conditioning is in its filter screen, so even if they have the habit of cleaning the air conditioner, they just wash the filter screen. But the real source of air conditioning pollution lies in the core component of air conditioning - radiator. According to the investigation of the relevant departments on the household air conditioner, more than 80% of the total number of bacteria in the heat sink of the air conditioner exceeds the standard, and the most serious one exceeds the standard by more than 1000 times. In addition, a large number of Staphylococcus aureus, Legionella, bacillus, influenza virus and so on can be detected. Therefore, it is very important to clean and disinfect the radiator carefully and thoroughly.
It is understood that cleaning air conditioning radiator needs to buy professional air conditioning disinfectant. When cleaning, first turn off the power supply of the air conditioner, then open the surface panel of the air conditioner, remove the filter screen and air purification filter, and then you can see the heat sink. Then shake the disinfectant evenly, disperse the heat sink about 5cm, spray and wash the whole radiator in the order of up and down. Wait about 15 minutes, install the filter screen, and then run the air conditioning refrigeration program for 15-30 minutes, so that the sewage will be discharged automatically with the drainage pipe. Generally, the doors and windows should be opened for about half an hour after disinfection, and the ventilation function should be used until the residual disinfectant has evaporated.
Experts pointed out that cleaning air conditioning radiator is a professional work, should try to invite professional personnel to carry out; in the selection of air conditioning disinfectant, we should pay attention to the selection of products with relevant national safety certification and disinfection brand, so as to fully ensure the disinfection and sterilization effect and human health and safety.
