Abstract
(EN) An air conditioner (1) wherein a gas purging control is performed, whereby a receiver gas purge valve (30a) is opened, thereby introducing a gas refrigerant from a receiver (25) into the intake side of a compressor (21) through a receiver gas purge pipe (30), and an upstream expansion valve degree of supercooling control is performed, whereby the degree of opening of upstream expansion valves (24, 26) is changed such that the degree of supercooling of the refrigerant at the outlet of radiators (23, 41) reaches a target degree of supercooling, and a downstream expansion valve intake moisture control is performed, whereby the degree of opening of downstream expansion valves (26, 24) is changed such that the refrigerant at the outlet of the radiators (41, 23) is in the wet state and the degree of dryness of the refrigerant reaches a target degree of dryness.
(FR) L'invention concerne un climatiseur (1) dans lequel une commande de purge de gaz est réalisée, une soupape de purge du gaz de récepteur (30a) étant ainsi ouverte, pour introduire ainsi un réfrigérant gazeux provenant d'un récepteur (25) dans le côté admission d'un compresseur (21), par le biais d'un tuyau de purge de gaz de récepteur (30), et un contrôle du degré de sur-réfrigération du détendeur en amont est réalisé, le degré d'ouverture des détendeurs en amont (24, 26) étant modifié de sorte que le degré de sur-réfrigération du réfrigérant à la sortie de radiateurs (23, 41) atteigne un degré cible de sur-réfrigération, et un contrôle de l'humidité en entrée du détendeur en aval est réalisé, le degré d'ouverture des détendeurs en aval (26, 24) étant modifié de sorte que le réfrigérant, à la sortie des radiateurs (41, 23), soit à l'état humide et que le degré de siccité du réfrigérant atteigne un degré cible de siccité.
(JA)  空気調和装置(1)では、レシーバガス抜き弁(30a)を開けることによってレシーバガス抜き管(30)を通じてレシーバ(25)から圧縮機(21)の吸入側にガス冷媒を導くガス抜き制御を行い、放熱器(23、41)の出口における冷媒の過冷却度が目標過冷却度になるように上流側膨張弁(24、26)の開度を変更する上流側膨張弁過冷却度制御を行い、蒸発器(41、23)の出口における冷媒が湿り状態でかつ冷媒の乾き度が目標乾き度になるように下流側膨張弁(26、24)の開度を変更する下流側膨張弁吸入湿り制御を行う。
