VENTILATION DESIGN
General project guidelines
The project of ventilation, air conditioning and anti-smoke measures of the administrative building at the address: Moscow, ul. Boytsovaya, 6 is developed on the basis of architectural and construction drawings, technological tasks and in accordance with the following current regulatory documents:
SNiP 41-01-2003 * "Heating, ventilation and air conditioning",
SNiP 23-01-99 "Construction climatology",
SNiP 23-02-2003 "Thermal protection of buildings",
SNiP 31-04-2001 "Warehouse buildings"
SNiP 2.01.02-85 * "Fire Prevention Standards",
SNiP II-12-77 "Protection against noise",
SNiP 2-08-02-89 * "Public buildings and facilities"
SNiP 2-09-04-87 * "Administrative and residential buildings"
MDS 41-1.99 "Recommendations for smoke protection in case of fire"
Heat supply project
The heat supply of the ventilation systems and air-heat curtains is provided from the coolant coming from the heat networks with parameters 80-60 ° C.
Systems are connected in an independent circuit through a heat exchanger.
Ventilation design documentation
In all areas of the building, a system of general exchange supply and exhaust ventilation has been designed in accordance with the applicable rules and regulations, technological tasks of specialists of adjacent sections and the customer’s design specifications.
For the premises of the basement and the 1st floor, the P1 / B1 system is provided, for the second floor - P2 / B2 and B3 (kitchen).
Air exchange in the premises is determined taking into account the norm of the multiplicity n = 3 units / hour for the inflow of fresh air per person. The distribution of air through slotted diffusers (slots) company "Trox".
The installation includes heat exchanger blocks for heat recovery.
The air ducts in the project are made of galvanized steel. Air ducts of air conditioning systems are subject to thermal insulation with K-Flex material 13 mm thick.
Ventilation equipment provided by the company "Zehnder" and "Systemair". All equipment is located on the roof.
Transit air ducts are laid in mines with a standardized fire resistance.
Anti-smoke measures
Smoke removal from the premises of the lobby of the 1st floor is carried out using the system DU1. To create air overpressure in the staircase and the lift shaft, the installation of the PD1 system is envisaged.
Fire retardant valves are installed on the air ducts. The sections of the air ducts from the fire-retarding valve to the fire barrier, as well as transit valves, should be insulated with a non-combustible material.
Acoustic events
To exclude the penetration of noise and vibration from operating fans into the premises, measures have been developed that exclude the propagation of noise and vibration, namely:
- installation of ventilation and refrigeration equipment on vibration isolators;
- connection vent. installations and air ducts through flexible inserts;
- installation of noise suppressors, etc.
DESIGN DOCUMENTATION OF VENTILATION
Automatic regulation and control
Provision is made for local and remote monitoring of the system parameters, an alarm about the operation and emergency condition of the equipment in the premises.
Energy saving
In order to reduce the cost of heat and electricity, the operation of heating and ventilation systems is automated. Download the project in dwg
