A vehicular air conditioner which is not influenced by fluctuations in engine RPM and which provides air conditioning with low energy consumption includes a variable demand capacity compressor where the suction pressure is self-controlled and can be set using an external signal. The vehicular air conditioner includes a demand capacity change compressor which self-controls at a target suction pressure set using an external signal and based on a discharge temperature set according to an air conditioning load. The external signal sets the target suction pressure to thereby affect a refrigerating cycle operation.

[ What is claimed is:] [1.]1. A vehicular air conditioner comprising:a demand capacity change compressor configured to self-control at a target suction pressure set using an external signal and based on a discharge temperature set according to an air conditioning load,wherein the target suction pressure is determined in accordance with said discharge temperature and the external signal is input to said demand capacity change compressor to thereby affect a refrigerating cycle operation.
