HFO Refrigerants. HFO (hydrofluoro-olefin) refrigerants are the fourth generation of fluorine-based refrigerants. HFC refrigerants are composed of hydrogen, fluorine and carbon atoms connected by single bonds between the atoms.
A refrigerant is a substance or mixture, usually a fluid, used in a heat pump and refrigeration cycle.In most cycles it undergoes phase transitions from a liquid to a gas and back again.Many working fluids have been used for such purposes. R-401A is a HCFC zeotropic blend of R-22, R-152a, and R-124. 2  It is designed as a replacement for R-12. 3  R-404A is a HFC nearly azeotropic  blend of 52 wt.% R-143a, 44 wt.% R-125, and 4 wt.% R-134a. 4  It is designed as a replacement of R-22 and R-502 CFC.
