Abstract
【解決手段】空調ユニット(1)は一次回路及び二次通路を有する。一次回路はコンプレッサ(5)、冷媒から環境への熱伝達のための熱交換器(2)、第1の絞り要素(11)及び乗員室の空気から冷媒への熱入力のための熱交換器(3)を有する。二次通路は2つの部分(15,16)を有し、分岐箇所(6)から始まる第1の部分(15)は入口箇所(14)まで延びる。第1の部分には冷媒から乗員室の空気への熱伝達のための熱交換器(4)が設けられ、第2の絞り要素(12)が熱交換器(4)の下流側に設けられる。分岐箇所(13)から始まる第2の部分(16)は、入口箇所(7)まで延びる。
【選択図】図1
Description
・乗員室の空気の除湿と加熱が同時に行われる。
・再循環作動を可能にすることによりヒートポンプに必要な最大熱出力が減少し、第2のガスクーラの上流側の空気温度が、ヒートポンプのオンへの切り換え後、非常に迅速に上昇する。
・同等の機能を備えた他の補助加熱システムと比較して、動的挙動が向上すると共に複雑さが減少する。
・電動式コンプレッサを任意的に用いている間、加熱能力がエンジンとは独立して利用できる。
・「自由な」周囲熱を用いることにより車両の燃料消費量が減少する。
・能動的コンポーネント(コンプレッサ、能動的切り換え弁、外部で調節可能な膨張弁)の数の減少の結果として、空調ユニットの製造の際のコストが節約される。
