Freon 12 (cf2cl2) code R12 Freon 12 is a colorless, odorless, transparent, almost non toxic refrigerant, but when the air content is more than 80%, it will cause suffocation. Freon 12 does not burn or explode. When it is in contact with an open fire or at a temperature above 400 ℃, it can decompose hydrogen fluoride, hydrogen chloride and phosgene (CoCl2) harmful to human body.
R12 is a widely used medium temperature refrigerant, suitable for small and medium-sized refrigeration systems, such as refrigerators, freezers, etc. R12 can dissolve a variety of organic matters, so it is not allowed to use ordinary rubber gasket (ring), usually chloroprene rubber or butadiene rubber sheet or sealing ring. 
Freon 22 (chf2cl) code R22 R22 does not burn or explode, and its toxicity is slightly greater than R12. Although the solubility of water is greater than R12, it may cause “ice jam” in the refrigeration system. R22 can partially dissolve with lubricating oil, its solubility changes with the type and temperature of lubricating oil, so the refrigeration system using R22 must have oil return measures.
The corresponding evaporation temperature of R22 under standard atmospheric pressure is – 40.8 ℃ The condensation pressure under normal temperature is not more than 15.68 × 105 PA, and the refrigerating capacity per unit volume is more than 60% larger than R12. R22 refrigerant is mostly used in air conditioning equipment.
