Abstract
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.
Claims6
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.
