HRAI released a statement revealing that fire services could be at an additional risk when responding if the building has a highly flammable hydrocarbon refrigerant in its air conditioning system.
The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) released the results of a research project, “Risk Assessment of Residential Heat Pump Systems Using 2L Flammable Refrigerants.”
A major concern in our industry today is the careless promotion of hydrocarbons, or hydrocarbon-based blends, as drop-in refrigerants. Even though HC’s do have many positive attributes, in their pure state they are classified A3, and therefore if misapplied can be very dangerous to use.
