1.Refrigerant R22, officially known as Chlorodifluoromethane, with the chemical formula CHClF ₂ and CAS number 75-45-6, belongs to the class of substances containing hydrochlorofluorocarbons (HCFCs).
2.Refrigerant R22 is a colorless, slightly sweet smelling transparent gas at room temperature and pressure. It is easily liquefied under pressure and has excellent thermodynamic properties and chemical stability. It is a widely used medium and low temperature refrigerant worldwide.
3.The refrigerant R22 has a molecular weight of 86.47, a critical temperature of 96.2 ℃, and a critical pressure of 4.99MPa. It has high refrigeration efficiency and strong adaptability, and has long been the core medium of the refrigeration and air conditioning industry. It is also an important chemical raw material.
Core product features
Excellent refrigeration performance: Refrigerant R22 has outstanding refrigeration efficiency in the medium and low temperature range (-80 ℃ to 10 ℃), high heat conduction efficiency, and large latent heat of evaporation (boiling point evaporation potential of 233.5 KJ/Kg), which can quickly achieve cooling and adapt to the working conditions of various refrigeration equipment.
Strong chemical stability: Refrigerant R22 does not react with commonly used materials such as metals, rubber, and plastics at room temperature, is non corrosive, and has stable chemical properties below 200 ℃. It may only decompose under high temperature or water conditions, ensuring long-term stable operation of the equipment.
Good compatibility: The refrigerant R22 is compatible with various refrigeration oils such as mineral oil, alkylbenzene oil, and polyester oil, without the need for significant modification of equipment lubrication systems, and is suitable for the design requirements of traditional refrigeration compressors.
Complete purity levels: Industrial grade refrigerant R22 has a purity of up to 99.8% or higher, with extremely low impurity content, moisture content ≤ 0.001%, acidity (calculated as HCl) ≤ 0.00001%, and evaporation residue ≤ 0.01%. It can effectively avoid equipment pipeline blockage and corrosion.
Multiple application scenarios: The refrigerant R22 has dual properties as both a refrigeration medium and a chemical raw material. It is not only suitable for various refrigeration systems, but also serves as a key intermediate in chemical synthesis, with applications covering multiple industrial fields.
