Title (EN) MULTI-SPLIT AIR CONDITIONING SYSTEM AND CONTROL METHOD THEREFOR
(FR) SYSTÈME DE CLIMATISATION À DIVISIONS MULTIPLES ET PROCÉDÉ DE COMMANDE ASSOCIÉ
(ZH) 多联机系统及其控制方法
Abstract:
(EN) A control method for a multi-split air conditioning system, the multi-split air conditioning system comprising a compressor and a plurality of indoor units (2) respectively arranged on a plurality of parallel branches, the indoor unit (2) comprising a fan (22), and the control method comprising: in a cooling mode of the multi-split air conditioning system, when the multi-split air conditioning system requires oil return, determining whether an indoor unit (2) in an off state has reached a condensing condition, opening the branch on which the indoor unit (2) is located, and implementing different control of the fan (22) of said indoor unit (2) on the basis of the determining results. Also provided is a multi-split air-conditioning system. The present multi-split air conditioning system control method and multi-split air conditioning system can effectively solve the problem of condensation dripping at an indoor unit triggered by the frequent oil return of a compressor, improving user comfort.
(FR) L'invention concerne un procédé de commande destiné à un système de climatisation à divisions multiples, le système de climatisation à divisions multiples comprenant un compresseur et une pluralité d'unités intérieures (2) disposées respectivement sur une pluralité de branches parallèles, l'unité intérieure (2) comprenant un ventilateur (22), et le procédé de commande consistant à : dans un mode de refroidissement du système de climatisation à divisions multiples, lorsque le système de climatisation à divisions multiples nécessite un retour d'huile, déterminer si une unité intérieure (2) dans un état éteint a atteint une condition de condensation, ouvrir la branche sur laquelle se trouve l'unité intérieure (2), et mettre en œuvre une commande différente du ventilateur (22) de ladite unité intérieure (2) sur la base des résultats déterminés. L'invention concerne également un système de climatisation à divisions multiples. Le présent procédé de commande de système de climatisation à divisions multiples et le système de climatisation à divisions multiples peuvent résoudre efficacement le problème de l'égouttement de condensation au niveau d'une unité intérieure déclenché par le retour d'huile d'un compresseur, ce qui améliore le confort de l'utilisateur.
(ZH) 一种多联机系统的控制方法,其中多联机系统包括压缩机和分别设置在多个并联支路上的多个室内机(2),室内机(2)包括风机(22),控制方法包括:多联机系统在制冷模式下,当多联机系统需要回油时,判断处于关机状态的室内机(2)是否达到凝露条件,将该室内机(2)所在的支路打开,并根据判断结果对该室内机(2)的风机(22)进行不同的控制。还提供了一种多联机系统。该多联机系统的控制方法及多联机系统能够有效解决压缩机频繁回油引起的室内机处出现凝露滴水现象的问题、提高用户使用舒适度。
