Mention of the refrigerants that are closely related to the chiller industry, refrigeration and cooling industry, etc., has always been one of the objects that attracted much attention. Many friends who know about refrigerants have many misunderstandings, so this article is mainly for everyone. Explain the five common misunderstandings related to refrigerants, as follows:
The air in the air-conditioned room does not need to be replaced (misunderstanding 1)
Many air conditioners now carry functions such as negative ions and oxygen bars. Many users think that the air cooled by these air conditioners is very beneficial to health. In fact, this view is incorrect. The most beneficial to human health is natural air. Special reminder: When using the air conditioner for a long time, users should open the windows regularly to allow the air in the room to form convection with the outside air. This is the best for health.
Only need to wash the filter when cleaning the air conditioner (misunderstanding 2)
The first is cleaning the internal machine. The filter must be cleaned, and the photocatalyst in the air conditioner needs to be exposed to the sun for ten minutes before use to maintain its function. If it has been used for a long time, there is a lot of wind and dust in the internal machine, and the evaporator needs to be cleaned. Air conditioners working in places with large oil fume need to be completely removed and thoroughly cleaned. In addition to the internal machine, the external machine must also be cleaned. If the external unit is not hung high outside, users can clean the condenser and heat exchange with clean water by themselves.
Canopy needs to be installed on the outside (misunderstanding 3)
In fact, if the external machine is hung in a good position, it is not necessary to shelter the wind and rain from the awning. Because the external machine is designed with waterproof, acid and rust-proof functions, no additional shielding is needed.
It doesn't matter if the air conditioner is not used for a long time (misunderstanding 4)
The core of an air conditioner's work is a compressor with lubricating oil inside it (Internet of Things trend). If it is not used for a long time, the lubricating oil will condense, and the compressor may be stuck when it is used again. Special reminder: In the season when the air conditioner is not used, it is best to keep the usage once a month.
Refrigerant needs to be changed once a year (misunderstanding 5)
Many users think that after using the air conditioner for a period of time, it is necessary to change the refrigerant. In fact, this view is incorrect. The claim that air conditioners require regular refrigerant changes is completely nonsense. The air conditioner is cooled by a refrigerant like a refrigerator, but since the refrigerator is a closed type refrigeration device, it is never necessary to add a refrigerant.
The air-conditioning refrigeration system is a semi-closed type. Generally, there will be refrigerant leakage in the refrigeration process, so sometimes it needs to add refrigerant. However, the leakage of refrigerant from each air conditioner is different, so there is no specific time, it must be replaced by the user. In fact, there are many air conditioners that use four or five years without adding refrigerant.
Avoiding the above five misunderstandings is a necessary condition for good refrigerant use. More relevant knowledge is available at http://ylscps.com
