Abstract
(EN) The air-conditioning unit according to the present invention comprises a check valve (2) provided between a four-way valve (3) and the discharge side of a compressor (1); a first electromagnetic valve (6) which is provided between an expansion means (5) and a room-internal heat exchanger (7) and can be controlled to open and close; and a control unit (9) for switching the four-way valve (3) and switching opening and closing of the first electromagnetic valve (6). When stopping a heating operation, the control unit (9) switches the four-way valve (3) connection from heating operation to cooling operation, closes the first electromagnetic valve (6) and then stops the compressor (1).
(FR) La présente invention concerne une unité de climatisation comprenant un clapet antiretour (2) prévu entre un distributeur à quatre voies (3) et la face d'évacuation d'un compresseur (1) ; une première électrovanne (6) qui est prévue entre un moyen de dilatation (5) et un échangeur de chaleur (7) à l'intérieur du local et qui peut être réglée pour s'ouvrir et se fermer ; et une unité de commande (9) permettant de commuter le distributeur à quatre voies (3) et de commuter l'ouverture et la fermeture de la première électrovanne (6). Lors de l'arrêt d'une opération de chauffage, l'unité de commande (9) fait passer le raccordement du distributeur à quatre voies (3) de l'opération de chauffage à l'opération de refroidissement, ferme la première électrovanne (6) et arrête ensuite le compresseur (1).
(JA)  圧縮機1の吐出側と四方弁3との間に設けられる逆止弁2と、膨張手段5と室内熱交換器7との間に設けられ、開閉制御が可能な第1電磁弁6と、四方弁3の切り替え、第1電磁弁6の開閉を切り替える制御装置9とを有し、制御装置9は、暖房運転を停止する場合において、四方弁3の接続を暖房運転から冷房運転に切り替え、第1電磁弁6を閉じ、その後に圧縮機1を停止するようにしている。
