What are the Hazards of Poor Quality Refrigerants?

hazards of poor quality refrigerants

Inferior refrigerants are generally mixed with a certain proportion of other chemical components in genuine refrigerants. The ingredients incorporated are mainly monochloromethane and dimethyl ether. The price of these chemical components is much lower than the cost of genuine refrigerants, and unscrupulous merchants profit from this. Refrigerants mixed with fake and inferior components will cause the following hazards:

1. Monochloromethane and dimethyl ether are both corrosive and have a serious corrosive effect on air-conditioning compressor components. They will dissolve rubber parts such as sealing rings in the system, and even the system will leak or even be completely paralyzed.

Many users will find that the air conditioner needs to be refilled every year after fluoridation, and it is very likely that counterfeit refrigerants have been added.

2. Since the pressure of the counterfeit refrigerant is lower than that of the genuine one, in order to achieve the standard pressure when adding fluoride to the air conditioner, it is necessary to overfill this refrigerant. The working principle of the compressor is to compress the gaseous refrigerant into a liquid refrigerant. When the amount of fluorine is too much, a large amount of liquid refrigerant that cannot be compressed will enter the compressor, resulting in a sharp increase in the pressure in the compressor, which can easily lead to the compressor being burnt out and scrapped. .

If your air conditioner compressor stops running shortly after fluoridation, you need to consider whether this is the cause.

3. Refrigerants such as R22 and R410A are non-flammable, so there is no need to consider this issue in system design. The chloromethane and dimethyl ether in the inferior refrigerant are flammable substances, which will cause explosion hazards when they are charged into the air-conditioning system. Therefore, with the proliferation of inferior refrigerants in recent years, news of air conditioner explosions will often appear in the media.

In addition, there are many unscrupulous merchants pouring low-cost refrigerants into high-cost refrigerant cylinders and selling them as high-priced products. For example, the price of R410a commonly used in inverter air conditioners is much higher than that of R22 refrigerants used in traditional air conditioners. Many businesses will pour R22 into R410a cylinders to pretend to be R410a refrigerants. This method of fraud does not produce the two hazards mentioned above. However, the refrigeration system is designed according to the applicable refrigerant itself, and the performance parameters such as pressure and evaporating temperature of each refrigerant are different. Using the wrong type of refrigerant is like inputting blood type B to a person with blood type A, and the system will have various uncomfortable reactions, such as poor cooling effect, high power consumption, frequent failures, and even system paralysis.
