Title (EN) REFRIGERATION CYCLE DEVICE
(FR) DISPOSITIF À CYCLE FRIGORIFIQUE
(JA) 冷凍サイクル装置
Abstract:
(EN) Provided is a refrigeration cycle device that has a circulation path for circulating a working medium containing 1,1,2-trifluoroethylene from a compressor to the compressor via a condenser, an expansion valve, and an evaporator. The refrigeration cycle device is provided with a composition change detection means, a composition adjustment means, and a control means. The composition change detection means detects that the composition of the working medium has changed from a steady composition. The composition adjustment means adjusts the composition of the working medium. The control means controls the composition adjustment means on the basis of a detection result by the composition change detection means.
(FR) L'invention concerne un dispositif à cycle frigorifique comprenant un circuit de circulation destiné à faire circuler un agent actif contenant du 1,1,2-trifluoroéthylène à partir d'un compresseur vers ledit compresseur par l'intermédiaire d'un condenseur, d'un détendeur et d'un évaporateur. Le dispositif à cycle frigorifique est muni d'un moyen de détection de modification de la composition, d'un moyen de réglage de la composition et d'un moyen de commande. Le moyen de détection de modification de la composition permet de détecter s'il y a une modification de la composition stable de l'agent actif. Le moyen de réglage de la composition permet de régler la composition de l'agent actif. Le moyen de commande permet de commander le moyen de réglage de la composition sur la base d'un résultat de détection par le moyen de détection de modification de la composition.
(JA) 冷凍サイクル装置は、1,1,2-トリフルオロエチレンを含む作動媒体を、圧縮機から、凝縮器、膨張弁、蒸発器を経由して圧縮機に循環させる循環経路を有するものである。冷凍サイクル装置は、組成変化検知手段と、組成調整手段と、制御手段と、を備える。組成変化検知手段は、作動冷媒の組成が定常の組成から変化したことを検知する。組成調整手段は、作動媒体の組成を調整する。制御手段は、組成変化検知手段による検知結果に基づいて組成調整手段を制御する。
