4.2 Design of exhaust system
(1) A layer to the three layer of the ready room with mechanical ventilation, natural ventilation, exhaust volume by 3 /h account.
(2). The piano room with mechanical ventilation, natural ventilation, exhaust volume by 3 /h account.
(3). The pump house located mechanical ventilation, natural ventilation, ventilation ventilation frequency 6 /h account at.
(4). The utility room, bathroom, dressing room with mechanical ventilation, natural ventilation, ventilation ventilation frequency 10 /h account at.
4.3 Smoke control system design
(1). A layer of report hall adopts mechanical smoke exhaust volume calculation, according to 60m3/h.m2, the blower is arranged on the roof.
(2). The multifunctional hall with three layers of natural smoke exhaust windows room area, area of not less than 2%, professional for architectural drawings,The aisle by natural ventilation.
(3) The exhaust fan centrifugal fan (30min satisfies the 280 C continuous work requirements), exhaust fan entrance should be installed to smoke fire valve closes automatically, and the chain to close the exhaust fan.
(4)Fan connected Import & export application hose, wherein when the fan for ventilation and smoke exhaust blower hose should satisfy (280 ° refractory 30min) requirements.
4.4 Selection of pipe
The selection of pipe is a process of economic technology, technology from pressure, temperature, environment for use, installation methods are considered, together with the customer's requirements and the quality of residential, economic technology determined after comprehensive consideration. Water supply pipe of the conventional galvanized steel, the galvanized steel pipe is easy to rust, short service life, used for conveying water can not meet the water quality health standards and other shortcomings, the Ministry of construction is to promote the application of plastic water supply pipe.
4.5 installation of pipeline
The wind pipe pipe made of galvanized steel system of conventional ventilation, wind pipe and fittings of the thickness of the plate according to "technical specification for ventilation pipeline JGJ141-2004" table 3.2.1-1 ventilation tube in low pressure (the exhaust pipe by high-pressure) system specifications, installation.
The wind pipe should be installed before the wind pipe internal clean, should be installed after the end of the opening up, construction always pay attention to keep the tube cleaning, to prevent the construction garbage into the wind pipe. 4 ventilation, air-conditioning system wind pipe connected with the fan, blower, air processor and other equipment should be set no fuel flexible wind material tube. All indoor air pipe fresh air inlet, the connection with the external air outlet adopts rainproof measures (not marked by all the equipment responsible.
