Introduction

The development of heating contributes to solving many important national economic and social problems, such as increasing the thermal and general economical efficiency of energy production, ensuring economical and high-quality electricity and heat supply to housing and communal and industrial complexes, reducing labor costs in the thermal economy, improving the environmental situation in cities and industrial areas.

Modern centralized heat supply systems are a complex complex, including heat sources, heat networks with pumping stations and heat points and subscriber inputs equipped with automatic control systems.

The purpose of this course work is to design and calculate the heat supply system of a residential area of ​ ​ the city.

The objectives of this course work are: calculation of quarterly passports; construction of wind force and repeatability rose and justification of choice of type and location of heat supply sources; determination of heat load of heat supply system; analysis of the annual heat consumption schedule; determination of coolant flow rates; hydraulic calculation of the heat network; calculation of thermal conductors for compensation of temperature deformations; calculation of thermal insulation of heat network pipelines; construction of temperature schedule of heat load release control.

The work takes into account technical, economic and environmental factors that determine the reliability and efficiency of the heat supply system.

Select Heat Supply Location

When choosing the location of the heat supply source, environmental, territorial administrative, energy, geological, hydrological, economic and other factors are taken into account in a comprehensive manner.

In this course design, the location of the heat supply source is selected on the basis of the following considerations:

- the preferred sector of location of the station should be chosen taking into account the terrain and climatic conditions of the settlement, in particular, the height of location of the station relative to other objects, the force rose and the repeatability of winds;

- when choosing the location of the station, it is necessary to take into account the presence and location of a water source, artificial and natural obstacles, passages and transport communications; consistent with the architectural and planning decision of the residential microdistrict, a possible direction of promising development of development.

Taking into account these factors, the northern sector of the general plan was chosen as promising for the location of the heat supply source of the designed residential microdistrict.

Conclusion

In accordance with the purpose of this course work:

1) calculation of quarterly passports;

2) construction of wind force and repeatability rose and substantiation of choice of type and location of heat supply sources;

3) determination of heat load of heat supply system;

3) analysis of the annual heat consumption schedule;

4) determination of coolant flow rates;

5) hydraulic calculation of the heat network;

6) calculation of heat conductors for compensation of temperature deformations;

7) calculation of thermal insulation of heat network pipelines;

8) construction of temperature schedule for control of heat load release.

The results of the calculations are illustrated by the corresponding diagrams.
