Abstract
A method for controlling a valve arrangement (), e.g. in the form of a three way valve, in a vapor compression system () is disclosed, the vapor compression system () comprising an ejector (). The valve arrangement () is arranged to supply refrigerant to a compressor unit () from the gaseous outlet () of a receiver () and/or from the outlet of an evaporator (). The vapor compression system () may be operated in a first mode of operation (summer mode) or in a second mode of operation (winter mode). When operated in the second mode of operation, it is determined whether or not conditions for operating the vapor compression system () in the first mode of operation are prevailing. If this is the case, the valve arrangement () is actively switched to the first mode of operation by closing a first inlet () towards the evaporator () and fully opening a second inlet () towards the receiver ().
