How to identify inferior refrigerant in high and low temperature damp heat test chamber

The refrigerant is the blood of the high and low temperature damp heat test chamber compressor. The purity of the refrigerant is especially important for the high and low temperature damp heat test chamber compressor. The most obvious phenomenon is: equipment filled with high purity refrigerant, cooling effect Obviously, the temperature drop is fast and the cooling capacity is large; the low purity refrigerant not only fails to reach the proper falling temperature, but also damages the compressor. We can identify whether it is a poor refrigerant by the following methods:

1. Whether to purchase refrigerants produced by regular manufacturers through formal channels, such as refrigerants whose prices are significantly lower than the market price, should be highly vigilant.

2. If you have test conditions, it is recommended to check the purity and acidity before using the refrigerant. It is not recommended for refrigerants whose test results are significantly lower than the industry standard.

3. If you do not have refrigerant detection conditions, it is recommended to perform a simple check before using the refrigerant. The simple check method can be:

(1) Invert the refrigerant tank and release a small amount of refrigerant onto a piece of white paper. If there are obvious impurities or liquid water on the white paper, the refrigerant quality is not good and it is not recommended.

(2) Connect the pressure gauge to test the refrigerant bottle pressure. Check the pressure and pressure characteristics of the refrigerant to check whether the pressure inside the bottle is within the normal range. If the pressure is abnormal, it is not recommended.
