Method for filling a coolant tank of a refrigerated vehicle and refrigerated vehicle

The method involves discharging a liquid cryogenic refrigerant in a liquefied state from a stationary storage tank (2) into a refrigerant tank (8) under effect of a pressure difference between the storage tank and the refrigerant tank. A part of the refrigerant is vaporized. The refrigerant that is vaporized during filling of the refrigerant tank, is partially collected and used for cooling a cooling chamber (12) of a cooling vehicle. A part of the vaporized refrigerant is supplied to the cooling chamber for direct cooling. An independent claim is also included for a cooling vehicle.
