Title (EN) VEHICLE AIR-CONDITIONING DEVICE
(FR) DISPOSITIF DE CLIMATISATION DE VÉHICULE
(JA) 車両用空気調和装置
Abstract:
(EN) Provided is a vehicle air-conditioning device that can comparatively simply determine whether a solenoid valve has failed. The present invention uses a controller to control a solenoid valve (17, 21, 30, 40) and thereby switches between a plurality of operation modes. When an operation state is presumed, on the basis of detected values for the temperature and/or pressure of parts, to have become abnormal as a result of the failure of the solenoid valve or of an outdoor expansion valve (6), the controller sets the rotational speed of a compressor (2) to a constant value and executes a failure confirmation mode for confirming the failure of the solenoid valve or of the outdoor expansion valve by a comparison of the detected values and normal detected values for temperature and/or pressure that have been pre-measured at the applicable rotational speed for the compressor.
(FR) La présente invention concerne un dispositif de climatisation de véhicule qui peut déterminer simplement si une électrovanne est défectueuse. La présente invention utilise un dispositif de commande pour commander une électrovanne (17, 21, 30, 40) et bascule ainsi entre une pluralité de modes de fonctionnement. Lorsqu'un état de fonctionnement est supposé, sur la base de valeurs détectées pour la température et/ou la pression de pièces, étant devenues anormales en raison de la défaillance de l'électrovanne ou d'un détendeur extérieur (6), le dispositif de commande règle la vitesse de rotation d'un compresseur (2) à une valeur constante et exécute un mode de confirmation de défaut afin de confirmer la défaillance de l'électrovanne ou du détendeur extérieur par comparaison des valeurs détectées et de valeurs détectées normales pour la température et/ou la pression qui ont été pré-mesurées à la vitesse de rotation applicable pour le compresseur.
(JA) 比較的簡単に電磁弁の故障を判定することができる車両用空気調和装置を提供する。 コントローラによって電磁弁(17,21,30,40)を制御することにより、複数の運転モードを切り換えて実行する。コントローラは、各部の温度、及び/又は、圧力の検出値に基づき、運転状態が、電磁弁又は室外膨張弁(6)の故障が原因と推定される異常状態となった場合、圧縮機(2)の回転数を一定の値とし、当該圧縮機の回転数で予め測定された温度、及び/又は、圧力の正常検出値と前記検出値とを比較することにより、電磁弁又は室外膨張弁の故障と確定する故障確定モードを実行する。
