Introduction

This project was developed in accordance with the requirements of SNiP23022003 "Thermal protection of buildings," SNiP230199 "Construction climatology," SNiP2.04.0591 * "Heating, ventilation and air conditioning."

In the course project, autonomous systems of a single-apartment residential building and an individual boiler room are being developed .

The following issues are addressed in the work:

1. heating - structural development of the heating system; calculation of heat losses of rooms; hydraulic calculation of pipelines; calculation of heating devices.

2. ventilation - design development of ventilation system; aerodynamic calculation of the system and selection of necessary equipment.

3. hot water supply - structural development of hot water supply system; hydraulic calculation of the system.

4. selection and binding of boiler room equipment.

1. design parameters of external and internal air

Outdoor air parameters of Ryazan according to Table 1 [2] are as follows:

cold period of the year

parameters B:

air temperature of the coldest five-day week, wasps,

security of 0.92 text = 27 ° С;

duration, day, period with average daily allowance

air temperature z = 208 days;

average air temperature, OS, tht = 3.5 wasps.

Design temperatures of internal air tint are accepted according to [4]. For the cold period of the year:

the angular living room - 22 wasps;

the living room - 20 wasps;

kitchen - 20 wasps;

San. knot - 24 wasps;

the hall - 18 wasps;

wardrobe - 18 wasps;

storerooms - 16 wasps;

hoz. rooms - 16 wasps;

the boiler house - 16 wasps;

vent. the camera - 16 wasps;

garage - 5 wasps.
