A method of operating a system for cooling an interior space in a vehicle, said space being occupiable by a driver or pilot of the vehicle, the vehicle including a drive for providing locomotive power thereto and being provided with a power source, and the system comprising: at least one refrigeration apparatus comprising a refrigeration circuit including a compressor, which is driveable by the power source, and an evaporator; an insulated reservoir holding a phase-change medium within which the/each evaporator extends, such that said medium can be cooled by the evaporator(s) to freeze from a liquid state; a cooling fluid circuit including a heat exchanger; a pump operable to pump the cooling fluid in the circuit from the reservoir to the heat exchanger and thence back to reservoir, whereby the frozen medium gradually melts; and means to effect a flow of air over the heat exchanger and into the interior space, wherein: during driving or piloting of the vehicle by the driver or pilot, when said drive is running, the power source drives the compressor(s) such that said medium is cooled by the evaporator(s) to an extent that an amount thereof freezes from said state; and thereafter, when said drive is not running and the driver or pilot, accommodated by said space, is resting or sleeping, the power source does not drive the compressor(s), the pump is operational, and said means effects said flow of air over the heat exchanger and into the interior space such that the interior space is cooled.
