Operating medium for carbon dioxide-cooling systems and air-conditioning systems

摘要

The invention relates to resource operating medium compositions containing additivated lubricants based on polyalkylene glycols and/or neopentyl polyol esters, which are additivated with alkylated triaryl phosphate esters which are suitable for lubricating refrigerators, air-conditioning systems, heat pumps and similar systems which are operated using carbon dioxide as an operating medium.
