Abstract: A picnic cooler that include a food compartment, a liquid-gas tank with an adapter, an electric spigot and a cooling apparatus. The food compartment includes a release aperture with unidirectional valve that is designed to release outside the gas. The cooling apparatus includes a twisting piping system and an upper metallic plate that serves also as the inner bottom of the food compartment and as a cooling plate. A second end of the twisting piping system includes a secondary aperture that is positioned inside the food compartment and that causes additional pressure drop and by that assists to cool the interior of the food compartment.

Abstract: An invention concerns a moisture control in a cryotherapy system and creating of snow mist. The system comprises a treatment chamber for at least one person, a closable entry to the treatment chamber, and a cooling apparatus. The cooling apparatus comprises an evaporator configured to function with a coolant and a valve for flow control of the coolant, wherein the evaporator is placed in the treatment chamber and the valve is coupled to the evaporator. The system further comprises a ventilation aperture for obtaining an additional air into the treatment chamber, the ventilation aperture being placed far from the evaporator to such spot that the additional air flows from the ventilation aperture towards the centre of the treatment chamber and simultaneously mixes with an air included in the treatment chamber so that water vapour of the additional air changes from gas to solid ice crystals and forms snow mist in the treatment chamber.

Abstract: A method for managing the operation of a refrigerated truck for transporting heat-sensitive products, of the indirect-injection type, in which the parameter ΔT=Tair inlet−Tsetpoint(Tair inlet: temperature of the air coming into contact with the heat exchanger internal to the truck as a result of the action of the fan, Tsetpoint: temperature to be set in the chamber inside the truck) is determined in real time and in which if ΔT is greater than an upper setpoint value ΔTsetpoint H, a rapid-pressurization (RMP) circuit is activated to vaporize some cryogen and thus increase the pressure in the head of gas above the reserve of cryogen of the truck.

Abstract: Cryogenic cooling apparatus is disclosed for cooling a target region using the demagnetization cooling effect. The apparatus has a primary magnet for providing a magnetic field within the target region and a demagnetization magnet arranged to selectively provide conductive cooling to the target region. A primary shielding magnet substantially cancels the magnetic field from the primary magnet at least at a first position between the primary and demagnetization magnets. A demagnetization shielding magnet substantially cancels the magnetic field from the demagnetization magnet at least at the first position between the primary and demagnetization magnets. Each of the primary shielding magnet and demagnetization shielding magnet comprises a cylindrical superconducting coil having a geometric envelope which encloses the primary magnet and demagnetization magnet respectively. A conductive cooling assembly provides conductive cooling to each of the magnets. A cryogenic system including a cryostat, the apparatus and a refrigeration system is also provided.

Abstract: A method for subcooling liquid cryogen that is used by a cutting tool uses the steps of dividing liquid phase cryogen between a subcooler feed line and tool feed line. The cryogen in the subcooler feed line is expanded to lower the pressure and decrease the temperature of the cryogen, and the expanded liquid cryogen from the subcooler feed line is added to the interior of a subcooler. A heat exchanger is positioned in the subcooler in contact with the expanded liquid cryogen. The cryogen in the tool feed line is subcooled below its saturation temperature by passing the cryogen through the heat exchanger, and the subcooled cryogen from the heat exchanger is supplied to the cutting tool. As a result, the subcooled cryogen supplied to the cutting tool is substantially 100% liquid cryogen without any vapor content.
