EPA Warns Against Use of Propane as Refrigerant Substitute

摘要

The U.S. Environmental Protection Agency (EPA) is warning homeowners, propane producers and sellers, and home improvement contractors and air conditioning technicians of potential safety hazards related to the use of propane or other unapproved refrigerants in home air conditioning systems. EPA is currently investigating instances where propane has been marketed and used as a substitute for HCFC-22 (R-22), a refrigerant that is widely used in home air conditioning systems.
