Abstract:
(EN) [Problem] To suppress power consumption in a heating mode. [Solution] This vehicular air-conditioning device is provided with: a refrigerant circuit provided with a compressor (18) which compresses a refrigerant, an outdoor heat exchanger (16) which exchanges heat between the refrigerant and the outside air, and at least one indoor heat exchanger (8, 10) which exchanges heat between the refrigerant and air delivered into a passenger compartment; and a plurality of electromotive automatic valves (20, 22, 28, 30, 32, 34) which are provided in the refrigerant circuit and which are for changing the flow path of the refrigerant in the refrigerant circuit in order to switch the operation mode of the vehicular air-conditioning device. The refrigerant circuit and a plurality of solenoid valves are configured so that when all the automatic valves are supplied with no power, a refrigerant flow path for the heating mode is formed.
(FR) La présente invention a pour objet de supprimer la consommation d'énergie dans un mode chauffage. L'invention concerne un dispositif de climatisation de véhicule comprenant : un circuit de fluide frigorigène pourvu d'un compresseur (18) destiné à comprimer le fluide frigorigène, un échangeur de chaleur extérieur (16) destiné à échanger de la chaleur entre le fluide frigorigène et l'air extérieur et au moins un échangeur de chaleur intérieur (8, 10) destiné à échanger de la chaleur entre le fluide frigorigène et l'air acheminé dans un compartiment passager ; ainsi qu'une pluralité de vannes automatiques électromotrices (20, 22, 28, 30, 32, 34) disposées dans le circuit de fluide frigorigène et destinées à modifier le trajet d'écoulement du fluide frigorigène dans le circuit de fluide frigorigène afin de commuter le mode de fonctionnement du dispositif de climatisation de véhicule. Le circuit de fluide frigorigène et une pluralité d'électrovannes sont configurés de sorte que, lorsque toutes les vannes automatiques ne sont plus alimentées, un trajet d'écoulement de fluide frigorigène pour le mode de chauffage soit formé.
(JA) 【課題】暖房モード時の消費電力を抑制する。【解決手段】車両用空調装置は、冷媒を圧縮する圧縮機(18)と、冷媒と外気とを熱交換させる室外熱交換器(16)と、冷媒と車室内に送られる空気とを熱交換させる少なくとも1つの室内熱交換器(8,10)と、を備えた冷媒回路と、冷媒回路に設けられ、車両用空調装置の運転モードを切り替えるために冷媒回路内での冷媒の流れ経路を変更するための複数の電動式の自動弁(20,22,28,30,32,34)とを備える。複数の自動弁の全てに電力が供給されていないときに暖房モードのための冷媒の流れ経路が形成されるように、冷媒回路及び複数の電磁弁が構成されている。
