Résumé

Lower global warming potential refrigerants tend to be highly flammable, and therefore, their safety evaluation is necessary. Pump-down is an operation used to collect the entire refrigerant in an air conditioner to its outdoor unit; however, some accidents have been reported where the compressor exploded owing to air contamination because of operational error. In this study, self-ignition of air, refrigerant, and lubricating oil were investigated experimentally. Additives to suppress combustion were mixed with oil and subsequently tested. Compared with the results of pure oil, the flammable range of the mixture became narrower for the oil mixed with the additives. It was revealed that the additives effectively suppressed the combustion at pump-down.
