Will r32, r410a, and r22 air-conditioning refrigerants explode? Why is it so?
Air conditioning is a common cooling and heating equipment. After the air conditioning has been used for a period of time, it may be necessary to add or replace the air conditioning refrigerant. At present, there are three most common air conditioning refrigerants on the market: r32, r410a, and r22. But is it true that the refrigerant is rumored to explode? Why is it so?
Reason one of the explosion caused by refrigerant: over-pressurization
The cause of the explosion may be caused by over-pressurization. Generally speaking, the pressure required for the internal refrigeration system of the air conditioner is clearly defined. A small pressure may lead to poor cooling and heating effects, but excessive pressure may cause an explosion. Because there is refrigerated oil in the compressor, which is a combustible gas, the pressure is too high, and the compressor shell may explode if it encounters air.
The second reason for the explosion caused by the r22 refrigerant: open flames and improper operation
Most of the air conditioners nowadays are inverter air conditioners, and the refrigerants used are R32 and There are many R410, and it will explode when it encounters an open flame. Open flames are forbidden within 5 meters of R32 refrigerant. In addition, if it is a central air conditioner, the compressor will explode if oxygen enters the compressor, and the air conditioner compressor has high and low pressure valves. If only one valve is opened, it is also prone to explosion. Another situation is that if the copper pipe is welded through the circuit, the refrigerant will explode when it escapes. According to Master Hong, the general air conditioner maintenance master knows how to operate, and most accidents like this are caused by the master's negligence and careless operation. currently, the cause of the incident is still under investigation.
Will r32 and r410a refrigerants explode?
R32 should be a refrigerant replacement model promoted by the environmental protection department in recent years. Now there are few that have really started mass application. Because this refrigerant is flammable, there are many problems that have not been resolved. The previous common R22, R410A, and R407C refrigerants have a high GWP (the index of the greenhouse effect of substances), which are non-environmentally friendly refrigerants and have a certain destructive effect on the climate.
1. R32 is a refrigerant, a new type of refrigerant. The inverter air conditioner model has the letter BP, and ZBP is the DC inverter air conditioner. There is no such two on the ordinary fixed speed air conditioner. Letters.
2. R32 refrigerant is a flammable and explosive refrigerant; if the air conditioner leaks a large amount of refrigerant in a short time and stays in a certain space, it is still dangerous of. If possible, it is not recommended to buy air conditioners using this type of refrigerant.
The above is the answer to the reasons why the three air-conditioning refrigerants r32, r410a, and r22 will explode. The editor kindly reminds you, do not smoke during the process of adding refrigerants , Choose a technician with a construction permit, and operate strictly according to the requirements.
