Traditional fluorocarbon-based refrigerants has become a concern due to their potential environmental impact. Hydrocarbons, such as propane (R-290), are viable refrigerant working fluids with zero ozone depleting potential and minimal global warming potential. Propane (R-290) is an ASHRAE class A3 refrigerant and the current barrier to more widespread application of such refrigerants is their flammability. While fundamental flammability characteristics are well established for most hydrocarbons, there is a need to assess the risks associated with their use as refrigerants and evaluate methods to mitigate such risks.
This webinar will discuss the recent Fire Protection Research Foundation project report, "Evaluation of the Fire Hazard of ASHRAE Class A3 Refrigerants in Commercial Refrigeration Applications". The specific objectives of the study were to: (1) assess the flammability risk versus charge size; and (2) develop recommendations on how to prevent or mitigate the risks when using Propane (R-290) in commercial retail and kitchen applications. The full final report is available from the FPRF website.
