Abstract:
(EN) Provided is a vehicle air conditioner such that the occurrence of poor lubrication caused by a decrease in the rotational speed of a compressor can be prevented. This vehicle air conditioner 1 comprises a compressor 2 for compressing a refrigerant and a heat pump controller for controlling the rotational speed of the compressor 2 to a predetermined target rotational speed. When changing the target rotational speed so as to be reduced, the heat pump controller performs target rotational speed change restriction control such that the target rotational speed is changed at a predetermined decreasing rate.
(FR) L'invention concerne un climatiseur de véhicule selon lequel l'apparition d'une mauvaise lubrification provoquée par une réduction de la vitesse de rotation d'un compresseur peut être empêchée. Ce climatiseur de véhicule (1) comprend un compresseur (2) permettant de comprimer un réfrigérant et un dispositif de commande de pompe à chaleur permettant de commander la vitesse de rotation du compresseur (2) à une vitesse de rotation cible prédéterminée. Lors de la modification de la vitesse de rotation cible pour sa réduction, le dispositif de commande de pompe à chaleur réalise une commande de restriction de modification de vitesse de rotation cible de sorte que la vitesse de rotation cible soit modifiée selon un taux de réduction prédéterminé.
(JA) 圧縮機の回転数が低下することで発生する潤滑不良の発生を未然に回避することができる車両用空気調和装置を提供する。車両用空気調和装置1は、冷媒を圧縮する圧縮機2と、この圧縮機2の回転数を所定の目標回転数に制御するヒートポンプコントローラを備え、ヒートポンプコントローラは、目標回転数を低下させる方向に変更する場合、所定の低下率にて当該目標回転数を変化させる目標回転数変更制限制御を実行する。
