R245fa

R245fa or HFC245fa is used as a third-generation alternative foaming agent to replace CFC. HCFC is used as a foaming agent for rigid polyurethane (PU) foams, used for polyurethane (PU) foaming of refrigerators, cold storage, and building boards, which also can be used for refrigeration. It replaces R-123 and R-22 refrigerants in central air-conditioning (chillers). Mainly used in organic Rankine cycle low-temperature waste heat power generation (ORC), foaming materials, heat pump systems, and other fields.

HFC245fa is a fluorinated hydrocarbon. It can be used as a refrigerant to replace R11 and R123 in new centrifugal chillers. The ozone depletion potential (ODP) is 0, which has little impact on the environment and is an environmentally friendly refrigerant.
