Title (EN) VEHICULAR AIR CONDITIONER
(FR) CLIMATISEUR DE VÉHICULE
(JA) 車両用空気調和装置
Abstract:
(EN) Provided is a vehicular air conditioner capable of eliminating the inconvenience that a compressor is operated in a state where the operational efficiency is low. The progress of frost formation on an outdoor heat exchanger 7 is determined on the basis of the difference ΔTXO = TXObase - TXO between refrigerant evaporation temperature TXO and refrigerant evaporation temperature TXObase when the refrigerant evaporation temperature TXO of the outdoor heat exchanger 7 becomes lower than the refrigerant evaporation temperature TXObase of the outdoor heat exchanger during no frost formation, or on the basis of the difference ΔPXO between refrigerant evaporation pressure PXO and refrigerant evaporation pressure PXObase during no frost formation. If the state in which the frost formation on the outdoor heat exchanger 7 is proceeding is maintained for a predetermined time period, a compressor 2 is stopped.
(FR) L'invention concerne un climatiseur de véhicule capable d'éliminer l'inconvénient selon lequel un compresseur est mis en fonctionnement dans un état dans lequel le rendement opérationnel est faible. La progression de la formation de givre sur un échangeur de chaleur extérieur (7) est déterminée en se basant sur la différence ΔTXO = TXObase - TXO entre la température d'évaporation du fluide frigorigène TXO et la température d'évaporation du fluide frigorigène TXObase lorsque la température d'évaporation du fluide frigorigène TXO de l'échangeur de chaleur extérieur (7) devient inférieure à la température d'évaporation du fluide frigorigène TXObase de l'échangeur de chaleur extérieur en l'absence de formation de givre, ou en se basant sur la différence ΔPXO entre la pression d'évaporation du fluide frigorigène PXO et la pression d'évaporation du fluide frigorigène PXObase en l'absence de formation de givre. Si l'état dans lequel il se produit une formation de givre sur l'échangeur de chaleur extérieur (7) est maintenu pendant une période prédéterminée, un compresseur (2) est arrêté.
(JA) 運転効率が低下した状況で圧縮機が運転される不都合を解消することができる車両用空気調和装置を提供する。 室外熱交換器7の冷媒蒸発温度TXOが無着霜時における室外熱交換器の冷媒蒸発温度TXObaseより低下したときの冷媒蒸発温度TXOと冷媒蒸発温度TXObaseとの差ΔTXO=TXObase-TXOに基づき、又は、冷媒蒸発圧力PXOと無着霜時の冷媒蒸発圧力PXObaseとの差ΔPXOに基づき、室外熱交換器7への着霜の進行状態を判定すると共に、当該室外熱交換器7への着霜が進行した状態が所定時間継続した場合、圧縮機2を停止する。
