Description

Ventilation Systems with vertical lifting in shafts and horizontal network along corridors are adopted. Air distribution is carried out using diffusers having architectural grids and ceiling plenum-exhaust diffusers at the end. All air distributors are equipped with air flow valves. The project used the equipment of the companies: "VTS CLIMA" and "Systemair." According to item 7.2.6. (MGSN 4.10-97), air inflow into the store of valuables is carried out through the preclade and inspection corridors, for which ventilation "ducks" from pipes d 76x3.5 with a horizontal pitch of 200 mm should be laid in the upper part of the common walls. To remove air, ducks are laid under the ceiling of the wall opposite to the location of the plenum holes. Pipe ends are connected from outside by air duct connected to exhaust ventilation system. The slope of the "ducks" must be provided from the storage room. According to VNP-001-95 in the archive and server rooms equipped with a gas fire extinguishing system, exhaust from the lower and upper zones in a ratio of 2:1 should be provided. Conditioning. To maintain comfortable parameters in the administrative-office premises of the bank of the 1st and 2nd floors of the right wing, the Mitsubishi Heavy multisonal air conditioning system was designed. The system FDCJ952HKXE2D is accepted for installation. The external units of the system are installed on the roof, the internal ones are embedded in the false ceiling. To maintain the required parameters in the dining room, an plenum plant with an air cooler is used. As a source of cold, the Clivet refrigerator is used. To maintain the required parameters, Liebert precision air conditioners are accepted for installation in the server and electrical panels. To maintain the required parameters in technical room 001, the Liebert channel air conditioner is accepted for installation. Measures to combat noise from ventilation installations. To reduce noise and vibration, the following measures are provided: - ventilation equipment is installed outside the serviced rooms; - ventilation plants include noise suppression sections; - noise silencers are installed on the main ducts; - the best speeds in the ducts are chosen; - connection to the ducts is carried out through flexible connections. Fire fighting measures. To prevent the spread of fire and smoke through air ducts, at the intersection of fire barriers, fire-retarding valves KLOP-1 and KOM-1 are installed. Air ducts from fire retardant valves to fire barriers shall be covered with fire retardant composition SGK-1 with fire resistance limit of 0.5 hours. Transit sections of air ducts pass in ventrates of construction design with a rated fire resistance limit. Upon a fire signal, all ventilation systems are switched off and smoke removal systems are turned on with the opening of fire valves. Automation and smoke ventilation projects are performed in separate volumes. Automation. The automation project performed in a separate volume provides for: - disconnection of all ventilation systems in case of fire; - closing of fire-retarding valves upon a fire signal; - control of all ventilation units from the dispatcher's board and at the place of their installation; - protection of heater from freezing and automatic maintenance of inflow temperature; - automation of air curtains U1-U3.
