pump, with a preparation, set 3 fire pump adapters.
Set a fire pond, the effective volume of it is 435m3. Set fire water tank, the effective volume of it is 28m3, no booster facilities.
The Natural ventilation and smoke exhaust system for the ground open parking garage. The standard floor zooning smokes control area by fixed type smoke wall, smoke control area is not supposed to be bigger than 500m3. Each partition takes the natural ventilation, which provides effective opening window area，which is 2% of the smoke control area. Two smoke-free stair rooms and a fire elevator are equipped.Pressurized air supply system is settled for smoke proof
staircase, antechamber, and its common antechamber. The pressurized air supply of the smoke proof staircase is 28200m /h, ten pre pressurized air supply is 12300m/h for common antechamber. The roof pressurization fan should be set up for axial flow fan with fire, staircase fan air volume 31690m no / h, residual pressure 653Pa, 15kw power and noise of 76dB (a), weight 430kg. The air blower room has 16557 m more than 535 Pa /h pressure, power of 7.5 kW, 71 dB noise (A), the weight of 320 kg.
The automatic alarm system selects smoke-sensing fire-detecting equipment, The building’s protection level is A so as to select centralized alarm system, and set the fire control room. Design choose the smoke detector, every layers pided into two detection unit, detector protection area is 60m2, protection radius is 5.8m. By calculation, the numbers of detectors arranged on the first floor are 26, 29 on the 16th floor,21 on 17th to 18th floor and 68 on the basement.
Key words: high-rise building; comprehensive office building; fire protection system design; hydrant system; automatic sprinkler system
