Title (EN) REFRIGERATION CYCLE DEVICE
(FR) DISPOSITIF DE CYCLE DE RÉFRIGÉRATION
(JA) 冷凍サイクル装置
Abstract:
(EN) A refrigeration cycle device (1A) is provided with: a main refrigerant circuit (10) including a compressor (11), a switching means (18), an indoor heat exchanger (12), an indoor-side pressure reducer (13), a gas-liquid separator (14), an outdoor-side pressure reducer (15), and an outdoor heat exchanger (16); and an injection path (17) for injecting a gas phase refrigerant, which is separated by the gas-liquid separator (14), into the compressor (11). The switching means (18) switches the direction of flow of a refrigerant flowing to the main refrigerant circuit (10) between the direction during cooling operation and the direction during heating operation. During heating operation or during heating operation under a specific condition, a refrigerant guided from the indoor heat exchanger (12) to the indoor-side pressure reducer (13) is heated by a heating means (20).
(FR) L'invention concerne un dispositif de cycle de réfrigération (1A) comportant : un circuit principal de fluide frigorigène (10) comprenant un compresseur (11), un dispositif de changement (18), un échangeur de chaleur intérieur (12), un manodétendeur côté intérieur (13), un séparateur gaz liquide (14), un manodétendeur côté extérieur (15), et un échangeur de chaleur extérieur (16) ; et une trajectoire d'injection (17) permettant d'injecter un fluide frigorigène en phase gazeuse, qui est séparé par le séparateur gaz liquide (14), dans le compresseur (11). Le dispositif de changement (18) change la direction de l'écoulement d'un fluide frigorigène s'écoulant vers le circuit principal de fluide frigorigène (10) entre la direction pendant une opération de refroidissement et la direction pendant une opération de chauffage. Pendant l'opération de chauffage ou pendant l'opération de chauffage dans une condition spécifique, un fluide frigorigène guidé en provenance de l'échangeur de chaleur intérieur (12) vers le manodétendeur côté intérieur (13) est chauffé par un moyen de chauffage (20).
(JA)  冷凍サイクル装置(1A)は、圧縮機(11)、切換手段(18)、室内熱交換器(12)、室内側減圧器(13)、気液分離器(14)、室外側減圧器(15)および室外熱交換器(16)を含む主冷媒回路(10)と、気液分離器(14)で分離された気相冷媒を圧縮機(11)にインジェクションするインジェクション経路(17)とを備える。切換手段(18)は、主冷媒回路(10)に流れる冷媒の流れ方向を冷房運転時と暖房運転時とで切り換える。暖房運転時または特定条件下での暖房運転時には、室内熱交換器(12)から室内側減圧器(13)に導かれる冷媒が加熱手段(20)により加熱される。
