  • Patent number: 9506681
    Abstract: The invention relates to a device and a method for generating a positive pressure in a tank for liquefied gas on a refrigerated vehicle with an evaporator for the liquefied gas, in conjunction with which the evaporator is connected in a fluid-conducting fashion to the tank via a line for liquefied gas, and in conjunction with which a valve is arranged in the line, comprising the following method steps: opening the valve so that liquefied gas exits from the tank and into the line; closing the valve in such a way that a quantity of the liquefied gas remains in the line and is able to flow back into the tank; heating the quantity in the line. The invention also relates to a method for the supply of liquefied gas, and a device for generating a positive pressure in a tank for liquefied gas in a cooling system, in conjunction with which the method according to the invention for generating a pressure is utilized.

  • Publication number: 20100251751
    Abstract: The invention relates to a method for monitoring the gas tightness of a cooling system for a refrigerated vehicle comprising the following steps: recording of a chronological temperature sequence at least at a first point in the cooling system and the determination of any change in the temperature at the first point within a first time interval and comparison of the change with a first reference value and the triggering of a first warning signal in the event that the change exceeds the first reference value; and/or subjecting a line section of the cooling system to a positive pressure and blocking this line section and recording a chronological pressure sequence at least at a first point in the line section and the determination of any change in the pressure in the second point within a second time interval and comparison of the change with a second reference value and the triggering of a second warning signal in the event that the change exceeds the second reference value.

  • Publication number: 20100050660
    Abstract: The invention relates to a mobile refrigerated vehicle comprising a refrigerated chamber housing for at least one refrigerated chamber contained therein, a tank for liquefied gas, an evaporator for the evaporation of the liquefied gas during the delivery of cold to the refrigerated chamber and an exhaust pipe for the evaporated gas, in conjunction with which the evaporator is arranged outside the refrigerated chamber; and a method for refrigerating a refrigerated chamber of a mobile refrigerated vehicle comprising the following process stages: removal of a liquefied gas from a tank and supply of the gas into an evaporator arranged outside the refrigerated chamber; removal of a flow of cooling air to be refrigerated from the refrigerated chamber, evaporation of the liquefied gas in the evaporator and utilization of at least one part of the cold content for the refrigeration of the flow of cooling air; introduction of the refrigerated flow of cooling air into the refrigerated chamber.

  • Publication number: 20090277188
    Abstract: The invention relates to a heat exchanger for a mobile refrigerated vehicle having a tank for liquefied gas comprising a pipe for accepting a flow of a liquefied gas and for the evaporation of at least one part of the liquefied gas, in conjunction with which the pipe, at least in sections, exhibits a longitudinal axis, and the heat exchanger comprises an inlet side for liquefied gas and an outlet side for at least partially evaporated gas, and in conjunction with which the outlet side is connected to an exhaust pipe in such a way as to permit a flow, in conjunction with which the pipe exhibits elements in its interior for the purpose of generating turbulences in the flow or a radial phase separation. The invention is characterized in that, with the help of the elements, the thickness of a gas interface layer on a wall of the pipe, which occurs as a result of vaporization of the gas, is reduced considerably, whereby the efficiency of the heat exchanger is increased considerably.
