If you do not have refrigerant testing conditions, it is recommended to perform a simple check before using the refrigerant. The simple check method can be:
(1)the refrigerant tank is inverted, and a small amount of refrigerant is released 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)press the pressure gauge to test the refrigerant bottle pressure, compare the refrigerant temperature and pressure characteristics table, check whether the pressure inside the bottle is within the normal value range, if the pressure is obviously abnormal, it is not recommended. And when the refrigerant is used halfway, the pressure inside the bottle can be tested again. For the single component refrigerant of R22, the pressure of the two measuring bottles should be very close, but for the inferior refrigerant, usually mixed with various components, the bottle After the use of the internal refrigerant, the bottle pressure will usually vary greatly due to the change of the composition ratio. If such a phenomenon occurs, it is recommended to immediately deactivate the refrigerant and discharge the refrigerant that has been charged into the system to avoid Pollution system
