Real Risks of Hydrocarbons
Published May 2012
Since China supplies nearly three quarters of the world demand for room air conditioners, the prospect that it intends to switch half its production of splits to propane (R290) to meet to 2015 phasedown from R22 has alarmed some sectors of the industry. The decision was taken following a comparison of the actual risk factors with the accepted public risk levels?a process known as quantitative risk assessment (QRA). This involved identifying potential leakage points and using computational fluid dynamics (CFD) to study the gas flow within a room and its tendency to concentrate near points of ignition such as electrical switches in the room and on adjacent equipment. The CFD results were calibrated from tests using actual equipment and a spark ignition source.
