METHOD AND DEVICE FOR GENERATING A POSITIVE PRESSURE IN A TANK FOR LIQUEFIED GAS ON A REFRIGERATED VEHICLE AND A COOLING SYSTEM FOR A REFRIGERATED VEHICLE AND A REFRIGERATED VEHICLE

摘要

The invention relates to a device and a method for generating a positive pressure in a tank (5) for liquefied gas on a refrigerated vehicle (2) with an evaporator (1) for the liquefied gas, in conjunction with which the evaporator (1) is connected in a fluid- conducting fashion to the tank (5) via a line (42) for liquefied gas, and in conjunction with which a valve (49) is arranged in the line (42), comprising the following method steps: opening the valve (49) so that liquefied gas exits from the tank (5) and into the line (42); closing the valve (49) in such a way that a quantity of the liquefied gas remains in the line (42) and is able to flow back into the tank (5); heating the quantity in the line (42).
