数据库记载的用途

Used as a foam blowing agent and refrigerant; [eChemPortal: SIDSUNEP]
HCFCs: Used as refrigerants, blowing agents, cleaning agents, and fire extinguishing agents (CFC alternatives); [HSDB]
Used in some sterilant mixtures and as a component in some replacements for CFCs as a refrigerant or for halon as a fire suppressant. Replaces CFC-114 in some heat pumps and special air conditioning equipment.
Minimally used as a refrigerant; its primary use as a refrigerant is in blends, mainly R-401A, in industrial process and transport refrigeration equipment. As a stand-alone refrigerant, it has found some niche applications that reach high condensing temperatures as well as an alternative for CFC-114 in some naval chillers.
HCFC-124 is classified as a partially halogenated chorofluorocarbon and was developed as a substitute for fully halogenated chlorofluorocarbons. HCFC-124's main use is in commercial applications as a blowing agent for polystyrene and polyolefin foams in addition to being a component in refrigerant blends. HCFC-124 is used either in closed systems (for refrigeration uses) or in well-ventilated areas with exhaust systems (in the case of appliance manufacturing)
HCFC-124 is a potential substitute for CFC-11 and CFC-12 use as blowing agent in polyurethane foams. /1-Chloro-1,2,2,2-tetrafluoroethane/
