Title
(EN) AIR CONDITIONER
(FR) APPAREIL DE CONDITIONNEMENT D'AIR
(JA) 空気調和機
Abstract
(EN)
A control portion (32) of an air conditioner (30) issues instructions to switch a four-way valve (10) and rotate a compressor (11) at a first number of rotations if an ambient temperature detected by a temperature sensor (12) is not more than a predetermined reference value when the air conditioner is switched from a defrosting operation to a heating operation. On the other hand, if the detected ambient temperature exceeds the reference value, the control portion (32) sets the number of rotations of the compressor (11) at a second number of rotations which is lower than the first number of rotations, and starts the heating operation. It is preferable that the first number of rotations is the maximum settable number of rotations, and the second number of rotations is set on the basis of the number of rotations of the compressor (11) at the heating operation just before starting the defrosting operation.
(FR)
L'invention concerne une partie commande (32) d'un appareil de conditionnement d'air (30) envoyant des instructions pour commuter une vanne à quatre voies (10) et faire tourner un compresseur (11) selon un premier nombre de rotations si une température ambiante détectée par une sonde de température (12) n'est pas supérieure à une valeur de référence prédéterminée quand l'appareil de conditionnement d'air est commuté d'un fonctionnement de dégivrage à un fonctionnement de chauffage. Par contre, si la température ambiante détectée est supérieure à la valeur de référence, la partie commande (32) règle le nombre de rotations du compresseur (11) selon un second nombre de rotations qui est inférieur au premier nombre de rotations, et démarre le fonctionnement de chauffage. Il est souhaitable que le premier nombre de rotations soit le nombre réglable maximum de rotations, et que le second nombre de rotations soit réglé en fonction du nombre de rotations du compresseur (11) au cours du fonctionnement de chauffage juste avant de démarrer le fonctionnement de dégivrage.
(JA)
 空気調和機(30)の制御部(32)は、除霜運転から暖房運転に切替えるとき、温度センサ(12)によって検出された外気温が所定の基準値以下の場合には、四方弁(10)に切替指示を与えるとともに圧縮機(11)を第1の回転数で回転させる。一方、検出された外気温が基準値を超えている場合には、制御部(32)は、圧縮機(11)の回転数を第1の回転数より低い第2の回転数に設定して暖房運転を開始する。好ましくは、第1の回転数は設定可能な最大の回転数であり、第2の回転数は、除霜運転を開始する直前の暖房運転時の圧縮機(11)の回転数に基づいて設定される。
