Air conditioners typically use refrigerants like R-410A or R-32, which are Hydrofluorocarbons (HFCs). R-410A is commonly used, while R-32 is gaining popularity due to its lower Global Warming Potential, according to Bajaj Finserv and FreQuip Rentals. Older ACs might use R-22, also known as Freon.

Air conditioners commonly use refrigerants like R-32, R-410A, and R-22. R-32 is a hydrofluorocarbon (HFC) refrigerant with a lower global warming potential than R-410A, while R-410A is another HFC refrigerant widely used in modern AC units. R-22 is a hydrochlorofluorocarbon (HCFC) refrigerant, which is being phased out due to its ozone depletion potential.

Nitrile Rubber insulation shows various properties due to its close cell and open cell structure. Closed cell Nitrile Rubber insulation has good thermal property while open cell structure provide good acoustic properties. It can be bifurcated in Class “O” and Class “1” on the basis of its fire resistance properties.
