According to the function of the room, centralized QuanLou supply, adopt fan-coil unit plus fresh air system independently. Wind system, fresh air units from outdoor fresh air into the indoor air enthalpy value, fan coil units to undertake indoor cooling load and part of all new rheumatoid load. Behavior by setting in the corridor ceiling air crew after processing into each room. Fan coil units use the supply side, in view of the model room air volume select tuyere, independent control of each room, meet the actual needs.
In the first place in the design of cold and heat load calculation, and then determine the air conditioning system, terminal devices selection, and then to carry on the plane layout, after the hydraulic calculation to determine the pipe and air pipe diameter, complete the floor plan design. In the design of air conditioning system have heat preservation, sound insulation and anti-corrosion design and anti-vibration design, etc.
Refuge floor is exclusively for high-rise building fire personnel temporary refuge floors. Fire cut is for firefighters in a certain height (greater than or equal to 100 meters of floor) set up temporary shelter in the room.
From the first floor to the first refuge floor high-rise building, the floor should not be more than 15 layer. Fires when gathered around in the 15th floor of seekers, if not the stair evacuation, fire truck available will be bailed out. Some of the current city fire truck, the biggest job height between 30 to 45. In addition, according to the requirements of the layout of all kinds of construction equipment and pipeline, and consider the use and management needs, after the completion of the gap between the refuge floor roughly around 15 layer, in this way, can control a range of evacuation time not too long, but also in the range of good saves from homework, at the same time can be combined with equipment layer.
Before the smoke prevention stair well (evacuation) and the room and before the fire elevator room as the main channel of evacuation and rescue, should be a separate partition smoke partitions, and set up independent smoke, the smoke exhaust facility. The safe evacuation, prevent spread of smoke and fire spread and vertical quickly save is very important.
Therefore the design of building refuge floor 6 layer, respectively, 22nd floor, 36 layer and 50. When a fire, 1 to 6 layers of staff can be directly through the fire elevator or smoke stair evacuation from the ground, 22 floors, 36 layer and 50 respectively hold its sheltering people between floors. Refuge floor are enclosed refuge storey building, so choose 22 refuge floor level as an example, pressurized air supply calculation and equipment layout. In refuge floor fan for refuge area and 22 to 35 layer of former room, room and before the fire elevator room pressurization design, choose centrifugal blower fan.
