Model: HIF-II (double speed) series fire exhaust fan, high temperature motors, totally enclosed motor built with high special motor cooling system efficiency, low noise, reasonable structure, small size, easy installation application: high-rise building , drying room, underground garage ventilation or high-temperature exhaust. Continuous operation at 300 degrees for 60 minutes or more high temperature, medium temperature conditions of continuous operation at 100 degrees 20 hours / time is not damaged, exhaust fan brand, fire is the ideal necessary equipment. As far as we designed several projects in recent years in terms such as Tian Mu Road Shanghai Railway Bureau electronic dispatch building, exhaust fan pictures, the building a total of 16 floors, basement (about 2000m2) for the parking garage. We consider the mechanical design and mechanical exhaust smoke, which set outlet in every stairwell, front room and other parts, by pressurized air supply fan, to form a positive pressure to prevent smoke intrusion, to ensure the safe evacuation . Set exhaust valve in the pipeline, the roof or the wall near the ceiling set exhaust port, Shuozhou exhaust fan, the smoke machine temperature flue gas exhausted to the outside. And in the case of a large area with a smoke partition, just behind where the smoke detector smoke alarm smoke partition. This is to prevent any expansion of the scope of smoke, exhaust fan applications, resulting in the proliferation of fireworks. Otherwise, not only affect the smoke effect, but also may be due to high temperature flue gas led to the non fire sprinkler nozzle rupture site and indiscriminate spraying, affecting both the fire effect, and cause unnecessary damage. How it works: the usual two-speed high-temperature exhaust fan at low speed in order to meet the exhaust air flow, when a fire occurs, the temperature exhaust fan in the cabinet under the joint control of the role of automatic high-speed operation, in order to meet the needs smoke, while the fire smoke No action exhaust pipe smoke damper partition and make air duct smoke damper was smoke and makeup air, automatic smoke damper other smoke partition automatically shut cabinet under the joint control of the action. When the smoke When the temperature reaches 280 ℃, automatic smoke damper will automatically shut down, exhaust fan and make the fan automatically stop. storey 3.5 m, a total of five smoke partitions, fire design incorporates air conditioning and ventilation systems and smoke exhaust system combined approach. selected two-speed high-temperature exhaust fan, high speed exhaust volume of 63500 m3 / h, low exhaust volume of 35400 m3 / h, the amount of fresh air and blowing up air units to 32000 m3 / h, discharge all with automatic smoke damper smoke fire damper. exhaust fan applications, Chen Yu-conditioned (online consultation), Shuozhou exhaust fan by Wu Cheng Chen-yu air-conditioning Limited.
