Beschreibung
Zusammenfassung:	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-opening 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.
