THERMALLY CONTROLLED SHIELDING MODULE OF VENTILATED UNDERGROUND Russian patent published in 2020 - IPC E04B1/78 E04C1/39 E04C2/52 

FIELD: construction.

SUBSTANCE: invention relates to construction, in particular can be used in enclosure of ventilated underground of building or structure, having the ability of natural ventilation and prevention of soil thawing in permafrost zone by means of automatic control of soil cooling process. Thermally controlled barrier module of ventilated underground (1) is a prefabricated structure of wooden glued panels, comprising front (2), rear (3) and panels (4) connecting them along the perimeter with a system of cross ribs (5) located between them, forming together with panels cavities (6) equipped with air-tight elastic hollow elements (7) with inlet channels (8) equipped with unidirectional valve (9), wherein in front (2) and rear (3) panels there are ventilation openings. Adjustable louvred grids (12) are integrated in the ventilation openings and connected to electric drive (18) of their movement to prevent heat transfer of heated flows (13) through enclosing module (1). At that, electric drive (18) of controlled louvered grids (12) is connected to the system for automatic control of the cooling process of the permafrost soil, including an air temperature sensor (14) installed in the cavity of enclosing module (1), connected to sensor input device for conversion of analogue signal into digital, a reprogrammable read-only memory (RROM) connected to said input device and an output device for converting a digital signal into an analogue signal, and the output device is connected to electric drive (18) of adjustable louvered arrays (12).

EFFECT: high efficiency of the thermoregulated shielding module of the ventilated underground due to controlled louvre arrays and use of an automatic control system to prevent heat transfer of heated flows in the warm period of the year into the space of the ventilated underground.
