Quantitative risk assessment of flammable refrigerants in room air conditioners.

Author(s) : COLBOURNE D., RITTER T. J.

Summary

A number of safety standards and guidelines specify requirements for air-conditioning equipment that use flammable refrigerants. It is important that safety and technical requirements be based on sound scientific judgment in terms of the likelihood of potential risks occurring. The paper develops the risk assessment strategy by considering the following factors in detail: refrigerant mass, room size, typical ignition sources, leakage from refrigerant systems, failure of unit components, building ventilation rates, build-up and decay of flammable concentrations and servicing. Results for normal operation, as well as for servicing, are presented.
