要約
(EN)
[Problem] To provide a vehicle air conditioner which improves heating capacity by suitably controlling the refrigerant supercooling degree in a radiator which satisfies both a high pressure and refrigerant flow rate during heating. [Solution] This vehicle air conditioner is provided with a compressor (2) which compresses the refrigerant, a radiator (4) which allows the refrigerant to dissipate heat, an external heat exchanger (7) which is provided outside of the vehicle cabin and allows the refrigerant to dissipate or absorb heat, and a controller. By means of the controller, the refrigerant emitted from the compressor (2) is allowed to dissipate heat in the radiator (4), and after reducing the pressure of said heat-dissipated refrigerant, a heating mode is run for allowing said refrigerant to absorb heat in the external heat exchanger (7). The controller (32) has a high-pressure preference mode in which the target radiator supercooling degree (TGSC) in the radiator is set higher in the direction in which the high pressure will be set to a prescribed high value, and a rotational speed preference mode in which the target radiator supercooling degree in the radiator is decreased in the direction in which the rotational speed of the compressor (2) will be set to a prescribed high value.

Le problème à résoudre dans le cadre de la présente invention consiste à fournir un climatiseur de véhicule qui améliore la capacité de chauffage en commandant de manière appropriée le degré de sous-refroidissement du fluide frigorigène dans un radiateur qui satisfait à la fois une pression élevée et un débit de fluide frigorigène élevé pendant le chauffage. La solution proposée consiste en un climatiseur de véhicule qui comprend un compresseur (2), qui comprime le fluide frigorigène, un radiateur (4) qui permet au fluide frigorigène de dissiper la chaleur, un échangeur de chaleur externe (7) qui est agencé à l'extérieur de l'habitacle du véhicule et permet au fluide frigorigène de dissiper ou d'absorber la chaleur, ainsi qu'un dispositif de commande. Au moyen du dispositif de commande, le fluide frigorigène émit depuis le compresseur (2) peut dissiper la chaleur dans le radiateur (4) et, après la baisse de la pression dudit fluide frigorigène ayant dissipé la chaleur, un mode de chauffage est mis en marche pour permettre au dit fluide frigorigène d'absorber la chaleur dans l'échangeur de chaleur externe (7). Le dispositif de commande (32) comporte un mode de préférence de pression élevée dans lequel le degré de sous-refroidissement du radiateur cible (TGSC) dans le radiateur est établi de sorte à être plus élevé dans la direction dans laquelle la pression élevée sera établie à une valeur élevée prescrite, et un mode de préférence de vitesse de rotation dans lequel le degré de sous-refroidissement du radiateur cible dans le radiateur est réduit dans la direction dans laquelle la vitesse de rotation du compresseur (2) sera établie à une valeur élevée prescrite.

【課題】暖房時に高圧圧力と冷媒流量の双方を満足する放熱器の冷媒過冷却度を適切に制御して暖房能力の向上を図ることができる車両用空気調和装置を提供する。 【解決手段】冷媒を圧縮する圧縮機2と、冷媒を放熱させる放熱器4と、車室外に設けられて冷媒を放熱又は吸熱させる室外熱交換器7と、コントローラを備える。コントローラにより、圧縮機2から吐出された冷媒を放熱器4にて放熱させ、放熱した当該冷媒を減圧した後、室外熱交換器7にて吸熱させる暖房モードを実行する。コントローラ32は、高圧圧力を所定の高い値とする方向で放熱器4の目標放熱器過冷却度TGSCを高くする高圧優先モードと、圧縮機2の回転数を所定の高い値とする方向で放熱器の目標放熱器過冷却度を低下させる回転数優先モードとを有する。
