1. Method of operating a cooling system (10) that is suitable in particular for cooling food on board an aircraft, comprising the steps:

  • producing cooling energy by means of a refrigerating device (12) andsupplying the cooling energy produced by the refrigerating device (12) to at least one cooling station (14) by means of a cooling circuit (16), circulating in which is a refrigerant, which upon release of its cooling energy to the at least one cooling station (14) is converted from the liquid to the gaseous state and is then converted back to the liquid state by means of corresponding pressure- and temperature control in the cooling circuit (16),characterized in that upon transfer of the cooling system (10) to its state of rest a control valve (44) disposed in the cooling circuit (16) is controlled in such a way that a desired operating pressure (pB) arises in the cooling circuit (16) is downstream of the control valve (44) and that refrigerant cooled by the refrigerating device (12) is received in a reservoir (30) disposed upstream of the control valve (44) in the cooling circuit (16).
