1. Introduction

The calculated building is the Cultural Tax Center. In the premises of such buildings, air conditioning systems or supply ventilation with mechanical motive are designed. In this work, we are making a project for a general supply and supply ventilation system.

In rooms, air parameters shall be provided by the ventilation system in accordance with the requirements according to SanPiN 2.1.2.1199-03:

1. Heating and ventilation systems shall provide the regulatory parameters of the microclimate:

air temperature in the warm period of the year may not be more than 3 ° С higher than the external design temperature for ventilation design;

the difference in horizontal air temperature (from the outer walls to any point inside the room) and vertical (between the floor and 1.5 m high) shall not exceed 2 ° C.

2. The content of harmful chemicals in the air of the working area should not exceed hygienic standards.

3. Ventilation systems shall be located in special rooms and isolated from ventilation systems of residential and public buildings.

2. Initial data

As an object for the design of ventilation systems, the Cultural and Scientific Center in the city of Ufa is proposed, in which inflow ventilation with mechanical motive is provided.

We define air exchange in the given room by calculation, in other rooms - by multiplicity of air exchange in accordance with reference data.

The calculation room is a circle room.

8. Conclusion

In this coursework, we designed a ventilation system for a cultural center located in the city of Ufa.

In the course of this course work, we determined the air exchange of general ventilation from the condition of removing hazards, determined the temperature of supply and removed air during the calculated air exchange, built the processes of changing air parameters on the J-d diagram:

determined the air exchange by standard multiplicity, according to calculations, the imbalance in the room is negative, thereby ensuring the removal of harmful substances and sharply expressed unpleasant odors;

selected the dimensions and number of air distribution grids;

arranged louver screens in each room and traced to separate plenum and exhaust systems;

performed aerodynamic calculation of each plenum and exhaust system, linked pressure losses;

selected ventilation equipment for supply and exhaust systems.

As a final stage, the cost of the entire common ventilation system was determined.

They also consolidated their knowledge of working with reference and regulatory literature, learned how to perform aerodynamic calculation of ventilation systems, select ventilation equipment, and got acquainted with the catalogs of various manufacturers of ventilation equipment.
