HFC-134a is used as refrigerant in automobile air-conditioning, household and commercial refrigerant applications. It can also be used as aerosol, flame retardan, and blowing agent in pharmaceutical, agro-chemical, cosmetics and cleaning sectors.

R-404A is formulated to closely match the properties of R-502, making it useful for a variety of medium and low temperature refrigeration applications. R-404A has been approved by many refrigeration compressor and system manufacturers for use in new refrigeration equipment such as food display and storage cases, cold storage rooms, ice machines, transportation, and process refrigeration.

R410A refrigerant is used in new residential and commercial air conditioning systems, heat pumps, dehumidifiers and small chillers. R-410A is also being considered in some medium temperature refrigeration applications.

As the long-term substitute for R502, R507 used mainly in the low temperature refrigeranting systems.

Applications include residential and commercial air conditioning systems, non-flooded evaporator chillers, and some commercial refrigeration systems. Since R-407C has similar properties to R-22, it is possible (with modifications) to use it in the same equipment designed for R-22 today.

R406A is used as refrigerant, can replace R12.

R-408A is a retrofit solution for medium and low temperature refrigeration systems that are currently using R-502. R-408A should not be mixed with R-502 or used to top off the charge of an existing system operating on R-502.
