Complement fan: especially in multilayer basement (eg: -2, -3 layer), the more the more less by the lower air passage communicating with the outside, alone smoke machine, resulting in greater negative pressure, reduce smoke efficiency, smoke exhaust fan slower adoption fill and send them to the outside air, reducing the negative pressure, so that the flue gas discharge pressure fan easier: general use in the stairwell and elevator room, not so toxic fumes enter. stairwell and down because it is China Unicom, so the pressure outlet can be open simultaneously, as long as the air evenly, it is generally done every 2 or 3 layers since the vertical blinds air. And it is not the front room Unicom swf row Smoke fan, so when the fire escape to the roof exhaust fan favor, considering htf exhaust fan vent open fire floor and the adjacent layers, so to make an electric outlet. dampers generally used instead of 280 degrees, 280 degrees, turn off the fuse Unlike the fire system linkage is found open fire signal ---- --- open the front pressurization fan the fire floor and the adjacent layers of the air chamber. a fan, positive pressure blower basic construction quality scale, and each sub-project seek exhaust fan, are the implementation of the "fire and electrical construction quality assessment scale" to achieve good levels. If the working conditions for such press fkcdf reincarnation cycle frequency of the oscillation frequency to cause resonance when the tune will happen. Homework hazard identification, risk assessment and control countermeasure another way to control the situation, see Schedule civilization identity construction requirements and recourse. Oil Cooler for petrol stations pressure test. The size of the table and the characteristic curves. Steel sub-project quality assessment. Figure seeking to build a water spray. Commissioning test project main bearing age. Rock wool insulation with plastic sheeting is cut concrete inside and outside temperature, temperature gradient control concrete, reduce the temperature stress of concrete internal control cracks. Efficacy in living side pressure drop size large yellow hydraulic cylinder chamber toward the "left" the underlying purpose of the movement angle opens up when the balance shall re-establish the curb appeal does not move. Axial flow rotor blades in accordance with the characteristic curve parallel axial flow experience when rendering plant following the occurrence of the phenomenon of fame missing indenter velocity flow velocity missing large pieces missing current speed noise significantly increase the chance of serious vibration occurs in the flue duct into " Automatic "and the case of missing another station speed parallel current volume flow pulsation pressure differences disappeared speed can not occur with large amplitude higher than that. swf exhaust fan | Watson conditioning (certified) | exhaust fan Watson provided by the Texas air-conditioning plant.
