Abstract

This paper presents one possible control strategy for a transcritical R744 automotive air conditioning system. The controller is developed for systems using clutch cycling, variable displacement, and variable speed compressors. The controller adjusts the high side pressure, blower speed, reheat, and modulates the compressor to achieve its goal. Test data is presented to support the claims and assumptions made and develop the controller.
