The refrigerant is sucked into a compressor, which then increases both the temperature and the pressure. Once the Freon vapor has been superheated, it is sent into the condenser. WebRefrigerants are assigned to one of four flammability classifications (1, 2L, 2, 3) with flammable refrigerants classified as 2L, 2, or 3. These toxicity and flammability characters combine to form a refrigerant safety classification (e.g., “A2L” or “B1”). Common examples of flammable refrigerants include R-290 (Class A3), R-152a (Class ...
