Cycle frigorifique transcritique à haute pression au CO2 pour le conditionnement d'air automobile.

A high-pressure transcritical refrigeration cycle with carbon dioxide for vehicle air conditioning.

Auteurs : KOEHLER J., SONNEKALB M.

Résumé

Carbon dioxide air conditioning units were installed in two city buses which were tested "on-the-road" during summer 1997 in Bad Hersfeld, Germany. By the end of August, the air condition systems of the two buses had been running together for more than 640 hours proving that CO2-systems fulfill important on-the-road requirements. In the first part this paper presents and discusses typical on-the-road data. In the second part of the paper the compressor of the transcritical cycle is discussed in detail. Indicator diagrams were measured with the first and secong generation of the compressor prototype.
