Introduction:
R152a or difluoroethane is an environmentally friendly medium-temperature refrigerant that replaces the refrigerant R134a. Difluoroethane is ozone friendly, has excellent thermodynamic efficiency, and has a very low global warming potential or GWP of only 124.
Specification:
| Name | Difluoroethane |
| Model | R152A,HFC-152a |
| Classification | HFC Refrigerant |
| Formula | C2H4F2 |
| Cas No. | 75-37-6 |
| Replacement for | Mainly R-134a |
Application:
R152a is commonly used as a propellant in aerosols, as a foaming agent, or as a component of refrigerant blends, however, its classification as a slightly flammable refrigerant has limited its use in automotive and commercial refrigeration. However, the recent Spanish taxation of fluorinated greenhouse refrigerants (with GWP greater than 150), as well as the limitations imposed by the F-Gas regulation in the face of global warming, has led to a renewed interest in flammable refrigerants, and even highly toxic refrigerants such as ammonia.
