Refrigerant concentrations in car passenger compartments.

Author(s) : MACLAINE-CROSS I.

Summary

Maximum refrigerant concentrations can be predicted from measured charge, leaks, volume and ventilation by simple formulae. Refrigerant 290/R600a is a popular "drop-in" replacement for 12, 134a and 406a in car air conditioners. Physically possible but improbable leaks of R290/R600a into the passenger compartment give concentrations above the lower explosive limit for four out of ten Australian cars tested. Simple precautions like placing the expansion valve in the engine bay avoid this.
