(1) "Inflatable Air Blower" main control parameters temperature, air flow, total pressure, efficiency, noise, electrical power, speed and shaft power of choice.
(2) In the medium temperature not higher than 85 ℃ conditions for higher exhaust fan should be a long run.
(3) exhaust fan should ensure that: When the transmission medium temperature at 280 ℃ continuous working time 30min, still continuous medium temperature cooling to room temperature during normal operation.
(4) In the rated speed, in the work area, measuring ventilator pressure curve and the curve given in the specification should meet the requirements: Axial exhaust fan in the provisions corresponding to ± 5% deviation of the pressure value.
(5) "Inflatable Air Blower" centrifugal expelling fan predetermined flow rate, ± 5% of the pressure value corresponding to the deviation.
(6) an indication of the operating point A sound level exhaust fan noise limits should be consistent with JB / T8690-1998 consistent.
(7) exhaust fan can be ordinary or special steel centrifugal exhaust fans axial fans. According to "fire protection design of tall buildings" in the provisions of fan specifications. The minimum air volume fan 7200 m / h, not more than 60,000 m / h, the maximum amount of wind (refers to the maximum volume of air smoke partitions).
(8) the exhaust air flow should increase the fan flow value of not less than 10% to 20% of the surplus amount.
(9) pressure ventilation exhaust system pressure should calculate the most unfavorable loop and ensure that the value of the residual pressure in the stairwell 40? 50Pa's. In front of the room residual pressure, common room, fire elevator room, refuge floors worth 25? 30PA's.
(10) fire exhaust fan should be consistent with the current standard JB / T10281-2001 comply "exhaust fan fire technical conditions."
(11) "Inflatable Air Blower" exhaust system should be set separately. Exhaust fans must be in the same location or upper smoke zone.
