Refrigerant R22
Details
Chlorodifluoromethane (HCFC-22), a colorless gas at room temperature, is a colorless, non - toxic, non-flammable and transparent liquid under the pressure created by itself. It has excellent thermal and chemical stabilities and no corrosivity to metals. Its main applications include refrigerant(-80℃grade), raw material for PTFE production and intermediate for Halon 1211 production.
Applications
R-22 is used in a variety of applications including residential and commercial air conditioning, refrigeration, chillers, room air conditioning, transport refrigeration and other comfort cooling and refrigeration applications.
