Description
図1は、本発明を適用した第1実施形態に係る車両用温度調節装置1を示すブロック図である。車両用温度調節装置1は、車両における熱負荷である電池(BATT)2の温度を冷凍サイクルなどの冷熱機器によって調節する。熱負荷は、電池2である。電池2は、車両の走行用の電動機に給電する二次電池である。電池2は、リチウムイオン電池などによって提供することができる。電池2は数百ボルトの出力を供給する。
図7は、本発明を適用した第2実施形態に係る車両用温度調節装置201を示すブロック図である。上記実施形態では、熱源装置37を設けることにより第3の加熱運転を提供した。これに代えて、熱源装置37を設けず、第3の加熱運転を実行しない車両用温度調節装置201を採用することができる。
図8は、本発明を適用した第3実施形態に係る車両用温度調節装置301を示すブロック図である。上記実施形態では、バイパス通路35を設けることにより第2の加熱運転と第3の加熱運転とを提供した。これに代えて、バイパス通路35を設けず、第2および第3の加熱運転を実行しない車両用温度調節装置301を採用することができる。この構成においては、第2の加熱運転に代えて、送風機32aを停止する運転を実行してもよい。具体的には、具体的には、制御装置5は、電池2を暖めるための熱を冷熱機器4が外気から汲み上げることができるとき、すなわち外気の温度が第3温度帯にあるとき、送風機32aを作動させる。そして、制御装置5は、電池2を暖めるための熱を冷熱機器4が外気から汲み上げることができないとき、すなわち外気の温度が第4温度帯にあるとき、送風機32aを停止させる。
図9は、本発明を適用した第4実施形態に係る車両用温度調節装置401を示すブロック図である。上記実施形態では、主ユニット6と熱交換器ユニット7とを構成して、装置を車両に搭載した。これに代えて、この実施形態では、複数の構成要素をユニット化することなく、車両に分散して搭載する。
図10は、本発明を適用した第5実施形態に係る車両用温度調節装置501を示すブロック図である。上記実施形態では、冷熱機器4は、基本的な構成をもつ冷凍サイクルであった。これに代えて、ホットガスバイパス機能を有する冷凍サイクルからなる冷熱機器504を採用することができる。冷熱機器504は、放熱器42を出た冷媒を、蒸発器44を通すことなく圧縮機41の吸入側に直接的に戻すホットガスバイパス装置545を備える。ホットガスバイパス装置545は、ホットガスバイパス通路と、その通路を開閉する弁とを備えることができる。この構成では、制御装置5は、加熱運転において、冷熱機器504がホットガスサイクルとして運転されるようにホットガスバイパス装置545を制御する。
図11は、本発明を適用した第6実施形態に係る車両用温度調節装置601を示すブロック図である。上記実施形態では、温度調節の対象、すなわち熱負荷は、電池2であった。これに代えて、温度調節が必要な種々の機器を熱負荷として採用することができる。例えば、図示の例においては、車両用温度調節装置601は、室内の空気の温度を調節する。すなわち、車両用温度調節装置601の熱負荷は、空調装置(HVAC)602である。
以上、本発明の好ましい実施形態について説明したが、本発明は上述した実施形態に何ら制限されることなく、本発明の主旨を逸脱しない範囲において種々変形して実施することが可能である。上記実施形態の構造は、あくまで例示であって、本発明の範囲はこれらの記載の範囲に限定されるものではない。本発明の範囲は、特許請求の範囲の記載によって示され、さらに特許請求の範囲の記載と均等の意味及び範囲内での全ての変更を含むものである。
