How to identify the authenticity of chlorodifluoromethane R-22 refrigerant?chlorodifluoromethane r22 refrigerant is used as a refrigerant for industrial, commercial, household and other air-conditioning systems; it can also be used as aerosol propellant and fire extinguishing agent for pesticides, paint spraying, and is also the basic raw material for the production of fluorine-containing polymer compounds.How to identify inferior chlorodifluoromethane r-22 refrigerant, first of all, when choosing a refrigerant, you must choose a brand refrigerant. For other refrigerants, we can use the following methods to make simple judgments:Method 1: Turn the refrigerant tank upside down and release a small amount of refrigerant on a piece of white paper. If there are obvious impurities or liquid water on the white paper, it means that the quality of the refrigerant is not good, and it is not recommended to use it;Honeywell chlorodifluoromethane r-22 refrigerant.jpgMethod 2: Connect the pressure gauge to test the pressure of the refrigerant bottle, compare the temperature and pressure characteristic table of the refrigerant, and check whether the pressure in the bottle is within the normal range. If the pressure is abnormal, it is not recommended to use.Method 3: When half of the refrigerant is used up, the pressure in the bottle can be tested again. For a one-component refrigerant such as chlorodifluoromethane r-22, the two measured bottle pressure values should be close, but for low-quality refrigerants, there are usually multiple components mixed. After the refrigerant in the bottle is used, the pressure in the bottle usually varies greatly due to the change of the composition ratio. Cleaner drains to avoid system contamination.Method 4: During the system debugging and operation stage, if the following abnormal phenomena are found1) When the cooling capacity of the system is insufficient and no other abnormality is found after inspection, you need to pay attention to the refrigerant; 2) When the filter or expansion valve of the system dryer is blocked, and the blockage is yellow-brown waxy or black sludge-like foreign matter, you need to pay attention to it. The refrigerant;3) If the high and low pressure pressure or temperature is abnormal when the system is running, or the system balance pressure is abnormal in the shutdown state (refer to the refrigerant temperature and pressure characteristic table), it is necessary to pay attention to the refrigerant.When these abnormal phenomena occur, it is recommended to extract the refrigerant from the system for purity testing to check the risk of inferior refrigerant.During this period, fluorine solvent from china recommends that the compressor side refrigerant be evacuated or the refrigerant of the whole system is released to avoid potential poor quality refrigerant coming into contact with the compressor and damaging it.
