Title
(EN) AIR CONDITIONER AND CONTROL METHOD THEREOF
(FR) APPAREIL DE CONDITIONNEMENT D'AIR ET PROCÉDÉ DE COMMANDE ASSOCIÉ
(ZH) 一种空调器及其控制方法
Abstract
(EN) Disclosed by the present application are an conditioner and a control method thereof, an outdoor unit of said air conditioner comprising an outdoor unit controller and a pressure sensor arranged in a connecting pipeline between a four-way valve and an indoor heat exchanger; the outdoor unit controller is used for: in response to not receiving a power-on signal outputted by an indoor unit controller, obtaining an initial internal pressure and end internal pressure of the connecting pipeline within a preset time by means of the pressure sensor; according to the initial internal pressure and the end internal pressure, calculating an internal pressure change value of the connecting pipeline within a preset time; according to the size relationship between the internal pressure change value and the preset pressure change threshold, determining the status of an indoor fan; the states of the indoor fan comprise a shut-down state and a running state; according to the state of the indoor fan, controlling the states of a compressor and an outdoor fan.
(FR) La présente divulgation concerne un appareil de conditionnement d'air et un procédé de commande associé, une unité extérieure dudit appareil de conditionnement d'air comprenant un dispositif de commande d'unité extérieure et un capteur de pression disposés dans une conduite de raccordement entre une soupape à quatre voies et un échangeur de chaleur intérieur. Le dispositif de commande d'unité extérieure est utilisé pour : en réponse à l'absence de réception d'un signal de mise sous tension délivré par un dispositif de commande d'unité intérieure, obtenir une pression interne initiale et une pression interne finale de la conduite de raccordement dans une période prédéfinie au moyen du capteur de pression ; en fonction de la pression interne initiale et de la pression interne finale, calculer une valeur de changement de pression interne de la conduite de raccordement dans une période prédéfinie ; en fonction de la relation de taille entre la valeur de changement de pression interne et le seuil de changement de pression prédéfini, déterminer l'état d'un ventilateur intérieur, les états du ventilateur intérieur comprenant un état d'arrêt et un état de fonctionnement ; en fonction de l'état du ventilateur intérieur, commander les états d'un compresseur et d'un ventilateur extérieur.
(ZH) 本申请公开了一种空调器及其控制方法,该空调器的室外机包括室外机控制器和设置在四通阀与室内换热器的连接管路内的压力传感器;室外机控制器用于:响应于未接收到室内机控制器输出的开机信号,通过压力传感器获取连接管路在预设时间内的初始内部压力和结束内部压力;根据初始内部压力和结束内部压力,计算连接管路在预设时间内的内部压力变化值;根据内部压力变化值与预设压力变化阈值之间的大小关系,确定室内风机的状态;其中,室内风机的状态包括停机状态和运行状态;根据室内风机的状态,控制压缩机和室外风机的状态。
