Title (EN) CONTROL METHOD AND CONTROL SYSTEM
(FR) PROCÉDÉ DE COMMANDE ET SYSTÈME DE COMMANDE
(ZH) 控制方法以及控制系统
Abstract:
(EN) Disclosed are a control method and a control system. A valve closing position of a valve device (1) can be controlled according to the current flow direction or working mode of a refrigerant. The stroke of the valve device (1) from a fully-open position to a fully-closed position is defined as a total valve closing stroke. When the flow direction of the refrigerant is a forward direction, the valve device (1) is controlled to run to a first valve closing position, and when the flow direction of the refrigerant is a reverse direction, the valve device (1) is controlled to run to a second valve closing position. The first valve closing position is different from the second valve closing position, and in this way, wear caused by valve closing can be reduced.
(FR) L’invention concerne un procédé de commande et un système de commande. Une position de fermeture de soupape d'un dispositif de soupape (1) peut être commandée en fonction de la direction d'écoulement actuelle ou du mode de fonctionnement d'un fluide frigorigène. La course du dispositif de soupape (1) d'une position complètement ouverte à une position complètement fermée est définie en tant que course totale de fermeture de soupape. Lorsque la direction d'écoulement du fluide frigorigène est une direction vers l'avant, le dispositif de soupape (1) est commandé pour passer à une première position de fermeture de soupape, et lorsque la direction d'écoulement du fluide frigorigène est une direction inverse, le dispositif de soupape (1) est commandé pour passer à une seconde position de fermeture de soupape. La première position de fermeture de soupape est différente de la seconde position de fermeture de soupape, et de cette manière, l'usure provoquée par la fermeture de soupape peut être réduite.
(ZH) 一种控制方法以及控制系统,能够根据当前制冷剂的流向或工作模式控制阀装置(1)的关阀位置,定义阀装置(1)从全开位置到全关位置的行程为关阀总行程,制冷剂流向为正向时,控制阀装置(1)运行到第一关阀位置,制冷剂流向为反向时,控制阀装置(1)运行到第二关阀位置,第一关阀位置和第二关阀位置不同,这样可以降低关阀磨损。
