ABSTRACT:
The use of pentafluoropropene (HFO-1225) and tetrafluoropropene (HFO-1234) in refrigeration equipment is disclosed. These materials are generally useful as refrigerants for heating and cooling, as blowing agents, as aerosol propellants, as solvent composition, and as fire extinguishing and suppressing agents.
