Development of an automotive air-conditioning system using carbon dioxide.

[In Japanese. / En japonais.]


In the report, the features of the CO2 refrigeration cycle and a prototype automotive AC system are described in comparison with current HFC-134a systems. In the wind tunnel chassis dynamometer chamber test, the cooling capacity of the CO2 system was found to be almost the same as the current AC systems at car speeds of 64 and 32 km/h, but to be slightly lower under idle engine conditions.
