(EN) REFRIGERATION CYCLE DEVICE
(FR) DISPOSITIF À CYCLE FRIGORIFIQUE
(JA) 冷凍サイクル装置
要約
(EN)
This refrigeration cycle device comprises a refrigerant circuit, a control device, bypass piping, a refrigerant cooler, a second throttle device, and a control device temperature sensor. In the case that the opening degree of the second throttle device is controlled to an indicated opening degree that is equal to or less than a set opening degree, and when the temperature sensed by the control device temperature sensor is equal to or less than a set temperature, the control device performs foreign-matter-releasing control to increase the opening degree of the second throttle device and, after the opening degree has been increased, subsequently return the opening degree to the indicated opening degree.
(FR)
Ce dispositif à cycle frigorifique comprend un circuit de fluide frigorigène, un dispositif de commande, une tuyauterie de dérivation, un refroidisseur de fluide frigorigène, un second dispositif d'étranglement et un capteur de température de dispositif de commande. Dans le cas où le degré d'ouverture du second dispositif d'étranglement est commandé à un degré d'ouverture indiqué qui est égal ou inférieur à un degré d'ouverture défini, et lorsque la température détectée par le capteur de température de dispositif de commande est égale ou inférieure à une température définie, le dispositif de commande effectue une commande de libération de matière étrangère pour augmenter le degré d'ouverture du second dispositif d'étranglement et, après que le degré d'ouverture a été augmenté, remettre ensuite le degré d'ouverture au degré d'ouverture indiqué.
(JA)
冷凍サイクル装置は、冷媒回路と、制御装置と、バイパス配管と、冷媒冷却器と、第2絞り装置と、制御装置温度センサとを備える。そして、制御装置は、第2絞り装置の開度が設定開度以下の指示開度に制御されている場合において、制御装置温度センサの検知温度が設定温度以下である場合に、第2絞り装置の開度を大きくし、大きくした後に指示開度に戻す異物解放制御を行う。
