PROBLEM TO BE SOLVED: To provide an air conditioning system for an internal combustion engine motor vehicle configured that an air conditioning system which is compatible with an idling stop function and is used without driving an internal combustion engine can be installed in an internal combustion engine motor vehicle in a space-saving manner at a low cost.SOLUTION: An electric compressor 60 is used instead of an engine compressor 111 operated by an internal combustion engine 100, and an existing capacitor 113, an evaporator 117, and the like are used to constitute a heat pump type, heat exchange function part 110'. Power is supplied to the electric compressor 60 by converting DC of 24 V from a large-capacity battery 30 to DC of 360 V by a first DC/DC converter 41, and a compressor operation control signal is output from an operation control part 51 of an air conditioner control means 50 to the electric compressor 60 to operate the heat pump type, heat exchange function part 110' during the stop of the internal combustion engine 100 and to enable cooling inside a vehicle.SELECTED DRAWING: Figure 1
【課題】内燃機関エンジンを駆動させずに使用できるアイドリング・ストップ対応のエアコンシステムを、省スペース且つ低コストで内燃機関自動車に装備できるようにした内燃機関自動車用エアコンシステムを提供する。【解決手段】内燃機関エンジン100によって動作するエンジンコンプレッサ111に代えて電動コンプレッサ60を用い、既存のコンデンサ113やエバポレータ117等をそのまま使うことでヒートポンプ式熱交換機能部110′を構成し、大容量バッテリ30からの直流24Vを第1DC/DCコンバータ41にて直流360Vに変換して電動コンプレッサ60へ電源供給すると共に、エアコン制御手段50の動作制御部51からコンプレッサ動作制御信号を電動コンプレッサ60へ出力することで、内燃機関エンジン100の停止中でも、ヒートポンプ式熱交換機能部110′を作動させて車内冷房を可能にする。【選択図】図1
