METHOD AND DEVICE FOR THERMOSTATING OF PNEUMATIC STRUCTURE Russian patent published in 2000 - IPC

FIELD: pneumatic building structures used as production floor-areas, service rooms and temporary spaces, in particular, for mobile pneumorefrigerators. SUBSTANCE: structure is produced with functional layers in walls, a remeasured lay-out form of the external layer is introduced, an isothermal structure is installed on the fastening stage, locks are fixed by anchors. Turbine-driven refrigerating plant is started, air gets compressed in the compressor, cooling is accomplished in successively installed heat exchangers, expansion is performed in the external and internal turbo-expanders. Part of air is picked up from the compressor after the first heat exchanger, expanded in the external turbo-expander to a pressure below the atmospheric one, applied to the extreme sections and to the internal interlayer cavities of the structure walls, the rest part of air is cooled down in the second heat exchanger, expanded in the internal turbo-expander. The isothermal structure has separately cooled thermoinsulated central and extreme sections with locks, formed by a multilayer pneumoframe in the form of a set of round main and additional arches. EFFECT: enhanced economical efficiency of production of design form of isothermal structure that is stable in all operating conditions. 15 cl, 7 dwg
