We plan on several projects in recent years, but say that the kitchen exhaust fan, such as Tian Mu Road train halfway China Shanghai Branch Electronic Information Management Building, the building a total of 16 floors, the underground chamber (2000m2 top and bottom) of the brake library. In planning we consider the harm tobacco and machine smoke machine, both set outlet in every room floor escalator, front room and other locations, two-speed exhaust fan after fan pressurized air supply, it produces positive pressure and then curse file Flue violations in order to maintain peace dispersed. Set on the channel exhaust valves, top pull or move closer to the top of the wall is set to pull the exhaust port, the exhaust flue gas discharge machine Chu outdoor temperature is high. And screenings are set to large-amplitude surface hinder smoke partitions, just behind the smoke nuisance survey is reported in which the exhaust smoke partition. So as to expand and increase the pre-harm just smoke the field, causing a discrete fireworks. Otherwise, Taizhou exhaust fan, not only affects the smoke effect, but also may lead to the flue gas temperature due to high non fire sprinkler lotus position on their own tents and mess spray head fracture, affecting both the fire effect and cause unwanted infringement. GYF fire temperature exhaust axial fans Overview; 1, use: GYF fire temperature exhaust axial fans tested in accordance with GB50045 ~ 95 "fire protection design of tall buildings" and GB50067-97 "garage, repair garage, parking lot design fire protection ", is a new type of energy-saving fire exhaust fan. The fan can be used as various buildings dedicated fire smoke, but also for high-rise buildings, general building, underground garage, culverts and other mines of smoke and ventilation, such as underground repository for exhaust ventilation usually requires When the winds of revolution with smoke. 2, Structure: leaf type with axial flow: There GYF-I (single speed) and GYF-SI (double speed); two kinds of fire exhaust fan. Leaf type with oblique flow: There GYF-II (single speed) and GYF-S2 (double speed) of two fire exhaust fan. If users have higher requirements on noise, you can make GYF-BX silencer exhaust fan the fire. Fans can also be made vertical, vertical exhaust fan mounted on the roof to do with fire smoke. GYF fire temperature exhaust axial fans consists of five main components: (1) the impeller (2) motor (3) circulating air impeller (4) guide vanes, the inner tube, guide holes (5) of the outer cylinder. Due to limitations in the basement by the subsurface conditions and space, to meet the air flow and pressure conditions and other parameters, fire protection systems and smoke exhaust ventilation is usually used in combination, so we use two-speed fan in the underground garage, That is the same fans and the same duct. In general, as the exhaust ventilation fan running at low speed use, when a fire, fans immediately becomes the high-speed operation, used as a fire exhaust fan. Such a machine with two, not only to reduce the construction cost, space saving, more importantly, greatly improving the efficiency and reliability of the equipment. If the exhaust and smoke control are completely separate the two systems, and fire exhaust fan is only put into operation when the fire occurred, rarely used, then the failure is difficult to be discovered and get timely maintenance, and when the real fire , but also difficult to ensure smooth operational. The two-speed fan just to overcome this shortcoming, usually as an exhaust fan running, problems can be discovered in time and be repaired, always in a good state of readiness. Fire exhaust fan, Chen Yu-conditioned (certification), Taizhou exhaust fan by Wu Cheng Chen-yu air-conditioning Limited. Wu Cheng Chen-yu air-conditioning Co. (www.wccykt.com) is an industry leader in Shandong Dezhou, fans, ventilation equipment, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs ???
