R22 is a Hydrochlorofluorocarbon (HC FC )
R22 is a HCFC refrigerant (comprised of hydrogen, chlorine, fluorine, and carbon)
and is the most common refrigerant used in the world today. The air conditioning
industry is in the process of moving to HFC refrigerants
(comprised of hydrogen, fluorine and carbon) as they have no chlorine content
and zero O zone Depletion Potential (O DP).
R410A is a Hydrofluorocarbon (HFC )
Systems using R410A refrigerant run at a pressure of approximately 1.6 times that
of similar systems using R22 and the energy efficiency is comparable. The R410A
refrigerant is a 50:50 mixture of R32 and R125. It has a higher direct GlobalW arming
Potential (GW P) than R22 or R407c, but a much lower indirect GW P (CO 2
production at power station).
R407c is a Hydrofluorocarbon (HFC )
R407c is a mix of three refrigerants: R32, R125 and R134a - all of which boil at a
different temperature. R407c has a range or glide of approximately 5°C compared
with R410A which has less than 0.17K. In R407c, R32 provides the capacity,
R125 controls the flammability and R134a reduces the pressure.
