Title (EN) AIR CONDITIONER COMPRISING INRUSH CURRENT LIMITER CIRCUIT
(FR) CLIMATISEUR COMPRENANT UN CIRCUIT DE LIMITEUR DE COURANT D'APPEL
(JA) 突入電流制限回路を備えた空気調和機
Abstract:
(EN) Provided is an air conditioner comprising an inrush current limiter circuit (2) having: an NTC thermistor (4) to limit an inrush current applied instantaneously when turning on an alternating current power source (1); and a relay contact (5) that is connected in parallel to the NTC thermistor (4), that can be opened and closed, and that short circuits the NTC thermistor when in a closed state; wherein the overall air conditioner power consumption can be reduced with a simpler circuit configuration more meticulously than conventional equipment by way of being provided with a relay contact control unit (19) that controls the relay contact (5) so as to be in an open state if overall air conditioner power consumption would be lower by having the relay contact (5) in the open state rather than in a closed state and controls the relay contact (5) so as to be in the closed state if overall air conditioner power consumption would be lower by having the relay contact (5) in the closed state rather than in the open state.
(FR) L'invention concerne un climatiseur pourvu d'un circuit de limiteur de courant d'appel (2) comprenant : une thermistance CTN (4) conçue pour limiter un courant d'appel appliqué instantanément lors de la mise en marche d'une source d'alimentation en courant alternatif (1) ; et un contact de relais (5) qui est raccordé en parallèle à la thermistance CTN (4), qui peut être ouvert et fermé et qui court-circuite la thermistance CTN lorsqu'il est dans un état fermé. Grâce à une configuration de circuit plus simple, la consommation d'énergie globale du climatiseur peut être réduite plus efficacement qu'avec un équipement classique au moyen d'une unité de commande de contact de relais (19) qui commande le contact de relais (5) afin qu'il soit dans un état ouvert si la consommation d'énergie globale du climatiseur est inférieure lorsque le contact de relais (5) est dans l'état ouvert plutôt que dans un état fermé et commande le contact de relais (5) afin qu'il soit dans l'état fermé si la consommation d'énergie globale du climatiseur est inférieure lorsque le contact de relais (5) est dans l'état fermé plutôt que dans l'état ouvert.
(JA) 交流電源(1)の投入時に瞬時的に印加される突入電流を制限するNTCサーミスタ(4)とNTCサーミスタ(4)に並列に接続され、オープンとクローズとに開閉可能であると共にクローズ状態時に前記NTCサーミスタを短絡するリレー接点(5)とを有する突入電流制限回路(2)を備えた空気調和機において、リレー接点(5)をオープン状態にした方がリレー接点(5)をクローズ状態にするよりも、空気調和機全体での消費電力が小さくなる場合には、リレー接点(5)をオープン状態に制御し、リレー接点(5)をクローズ状態にした方がリレー接点(5)をオープン状態にするよりも、空気調和機全体での消費電力が小さくなる場合には、リレー接点(5)をクローズ状態に制御するリレー接点制御部(19)を備えたことにより、より簡易な回路構成で、従来よりも空気調和機全体の消費電力をきめ細かく低減させることが可能である。
