All air system refers to the indoor load all borne by the treated air to the air conditioning system. This system required air quantity, thus duct section size is bigger. The centralized air conditioning system generally belongs to such a system. Due to the large space indoor load is larger, compared with the secondary return air, the process is simple, operation management simple, simple equipment, initial investment is relatively small, so choose a return air constant single duct air system.
5 The ventilation design bathroom and shower room
Due to the toilet and shower room cannot be effective natural ventilation, so the mechanical exhaust. 1 layer on the right side of the shower room belongs to professional bath center, and no natural ventilation conditions, setting up air supply device to improve the indoor air. According to the number of air supply 8 times/h, exhaust number 9 times/h.
6 Smoke control systems
According to the code for fire protection design of high-rise civil buildings, in this design, in the following room set of smoke: hall 1 floor underground bars, dance floor, walkways, computer room and open office, banquet hall 1 layer, layer 2 of the lounge. The remaining rooms on natural smoke exhaust.
7 Duct and tuyere layout
The layout of duct is all along the beam, the entire air system air distribution in the form of sending last time. Tuyere has a key effect on air distribution, according to the back to choose appropriate outlet air flow and uniform distribution, and to avoid blocking column and beam, the biggest possible to reduce airflow disturbance have negative effect on air flow, to produce good air distribution effect. Follow the method of average layout in the design for uniform air conditioning area can supply.
