TECHNICAL DEVICE FOR EVOLVING THE PASSIVE BEHAVIOR OF FIRE-CUTTING DOORS TOWARDS ACTIVE FIRE RESISTANCE CAPACITY THROUGH FLUID HEAT PUMP

摘要

The invention relates to a device for the heat exchange function on the swinging and dormant parts of the fire door blocks by circulating a heat transfer fluid diffused through the hydrophilic mineral fiber. the device comprises a connection box to the primary heat transfer fluid inlet network fixed on the frame (1) and comprising a 3-way solenoid valve with pressure limiter (2) for a door swing inside distribution by an armed hose (3) fire resistant. The heat transfer fluid is distributed along the door leaf by an alloy ramp (4) having over its entire length diffusing orifices oriented towards inner faces of the walls. The coolant is diffused along the walls of the flap through the hydrophilic insulation (5) as well as inside the frame. The heat transfer fluid is captured in the lower position by a tray / strainer (6) flowing from top to bottom in continuous flow until the volume of the leaf. Another housing arranged in the lower position of the frame and comprising a 3-way distributor retrieves the heat transfer fluid to return to a network or an option not shown an external rainwater diffuser. the device according to the invention is particularly intended for the fire barrier function and the thermal regulation of closures for: establishments receiving the public (ERP), industrial storage and production premises classified or not classified in ICPE, laboratories, nuclear and thermal power plants, ships, marine equipment and OFFSHORE platforms, rail mobile equipment, mobile fire protection equipment, mobile power generation equipment (eg generator, compressor, etc ...), tunnels road, rail and mining, as well as technical galleries, ventilation networks, air or gas networks for technical processes, etc.
