Beware of misunderstandings: Does the air-conditioning refrigerant need to be replaced every year?_Maintenance

　　 Do you think that the air-conditioning refrigerant needs to be replaced once a year? Do you think that the air-conditioning in your home always fails? You still find that unexpected situations always occur in daily use? In fact, All are due to misunderstandings in our daily life.

　　 Today, I will bring you five common mistakes in the use of air conditioners in life. Those who don’t know how to maintain air conditioners should not miss it.

　　Misunderstanding 1: An awning should be installed when the outside machine is exposed

　　 In fact, if the outside machine is hung in a good position, you don’t need an awning to keep out wind and rain. Because the external machine is designed with waterproof, acid-proof, and rust-proof functions, no additional shielding is required.

　　Misunderstanding 2: It doesn’t matter if the air conditioner is not used for a long time

　　 The core of the air conditioner is the compressor, which contains lubricating oil. If it is not used for a long time, the lubricating oil will condense, which may cause the compressor to jam when it is used again.

　　 Special reminder: In the season when the air conditioner is not in use, it is necessary to keep the usage rate of turning on once a month.

　　Misunderstanding 3: Cleaning the air conditioner only needs to wash the filter

　　s* First, clean the internal machine. The filter must be cleaned, and the photocatalyst in the air conditioner needs to be exposed to the sun for more than ten minutes before it is used to maintain its function. If it is used for a long time, there will be more wind and dust in the internal machine, and the evaporator also needs to be cleaned. For air conditioners that work in places with a lot of oily smoke, the entire air conditioner needs to be removed and cleaned completely.

　　 In addition to the inner machine, the outer machine must also be cleaned. If the outdoor unit is not hung high outside, the user can clean the condenser and heat exchange with clean water.

　　Misunderstanding 4: The air in the air-conditioned room does not need to be replaced

　　 Many air conditioners now carry negative ions, oxygen bars and other functions. Many users feel that the air cooled by these air conditioners is very beneficial For health. In fact, this view is not correct. It is natural air that is beneficial to human health.

　　 Special reminder: When using the air conditioner for a long time, users should open the windows regularly to allow the air in the room and the outside air to form convection, so that it is beneficial to health.

　　Misunderstanding 5: The refrigerant needs to be changed once a year

　　 Many users think that the air conditioner must be changed after a period of time. In fact, this view is not correct. The statement that the air conditioner needs to change the refrigerant regularly is nonsense. The air conditioner is cooled by refrigerant like the refrigerator, but since the refrigerator is a closed refrigeration device, there is never need to add refrigerant.

　　The refrigeration system of the air conditioner is semi-closed. Generally, there will be refrigerant leakage during the refrigeration process, so sometimes it needs to add refrigerant. However, the refrigerant leakage of each air conditioner is different, so there is no specific time specified and the user must replace it. In fact, there are many air conditioners that can be used for four or five years without adding refrigerant.
