Abstract
A cooling system includes a compressor, a condenser, and an evaporator where a refrigerant is circulated, and a valve interconnected in the flow of the refrigerant from the condenser to the evaporator. The valve is configured to enter a first, open, state when the compressor is in an on-phase and to enter a second, closed, state when the compressor is in an off state by a controller. The controller controls the valve to operate in accordance with opening the valve at a first variable time period before the compressor is switched to an on-phase; where the first variable time period is set in response to an external parameter obtained by the controller, and/or closing the valve at a second variable time period before the compressor is switched to an off-phase, where the second variable time period is set in response to an external parameter obtained by the controller.
