要約
(EN)
[Problem] To provide a heat pump vehicle air conditioner that implements comfortable heating in a vehicle interior during travel and prolongs traveling distance by preventing or suppressing frost on an exterior heat exchanger when heating the vehicle interior in advance while the vehicle is plugged in. [Solution] The invention is provided with an injection circuit (40) that diverts a refrigerant which has exited a heat dissipater (4) and returns the refrigerant to a compression midpoint of a compressor (2). A controller has a frost estimation means that estimates frost on an exterior heat exchanger (7) and, in a heating mode which is implemented when electricity is supplied from an external power source to the compressor (2) or to a battery that supplies power in order to drive the compressor (2), the controller injects gas to the compressor (2) via the injection circuit (40) when frost on the exterior heat exchanger (7) is predicted.

Le problème décrit par la présente invention est de fournir une pompe à chaleur de climatiseur pour véhicule, mettant en œuvre un chauffage confortable dans un habitacle de véhicule en cours de déplacement et prolongeant les distances de déplacement en évitant ou supprimant le givre sur un échangeur de chaleur extérieur lors du chauffage de l'habitacle du véhicule, alors que le véhicule est branché. La solution selon l'invention consiste à fournir un circuit d'injection (40) qui dévie un réfrigérant, sorti d'un dissipateur de chaleur (4), et qui renvoie ledit réfrigérant vers un point médian de compression d'un compresseur (2). Une unité de commande possède un moyen d'estimation de givre, qui estime le givre sur un échangeur de chaleur extérieur (7) et, dans un mode de chauffage qui est mis en œuvre quand de l'électricité est fournie à partir d'une source d'alimentation externe au compresseur (2) ou à une batterie qui fournit de l'énergie afin d'entraîner le compresseur (2), l'unité de commande injecte du gaz vers le compresseur (2), par l'intermédiaire du circuit d'injection (40), lorsque la présence de givre est prédite sur l'échangeur de chaleur extérieur (7).

【課題】ヒートポンプ方式の車両用空気調和装置において、プラグイン中に予め車室内の暖房を行う際の室外熱交換器への着霜を防止し、或いは、抑制することにより、走行中における快適な車室内暖房を実現し、走行距離も延ばす。 【解決手段】放熱器4を出た冷媒を分流して圧縮機2の圧縮途中に戻すためのインジェクション回路40を備え、コントローラは、室外熱交換器7への着霜を推定する着霜推定手段を有し、外部電源から圧縮機2、若しくは、当該圧縮機2を駆動するために電力を供給するバッテリに給電されている状態において暖房モードを実行する際、室外熱交換器7への着霜が予測される場合、インジェクション回路40で圧縮機2にガスインジェクションを行う。
