RU2375642C1 - Method of supplying incoming air combined with air heating in multi-storey building - Google Patents

Abstract

FIELD: heating.

SUBSTANCE: method is aimed at the supply of incoming air in a multi-storey building. Incoming air is supplied from the building top to the intake ventilation unit, filtered by a fresh air fan and check valve, heated up to +21°C and fed to an air duct passing from top to bottom through all storeys. Afterwards the calculated volume of the incoming air is extracted from the common air duct through the flow distribution valves into separate flats; an air duct in the flat is equipped by a channel heater serving for heating of the air up to +70°C. The channel heater and respectively the temperature conditions in the flat are controlled from a control board installed in each flat. Positive balance of air pressure is produced in the flat, used air is withdrawn from the flat outdoors through the exhaust ventilation system comprising an exhaust air duct passing through all building storeys, an exhaust check valve, an exhaust fan removing used air from each flat.

EFFECT: ensuring optimal air supply.

Description

The invention relates to the ventilation and heating industry, and in particular to a method for supplying fresh air combined with air heating in multi-story buildings.

A known method, including combining ventilation and heating (Features of the distribution of warm air in rooms with air heating systems. Http://www.c-o-k.ru/showtext/?id=1192&from=online&params=num%3D11, 2006).

The disadvantage of this method is the insufficient supply of air and heating, at the same time, in a multi-storey building due to its technological features.

A known method adopted as a prototype, including combining ventilation and heating (ventilation systems. Http://www.inrost.ru/guide/ventilation/theory/systems.html, 2008).

The disadvantage of this method is also the insufficient supply of air and heating, at the same time, in a multi-storey building due to its technological features.

An object of the present invention is to provide an optimum air supply combined with air heating in a multi-story building.

This is achieved by the fact that the supply air, according to the norms, enters from above the building into the supply ventilation unit using a calculated supply fan, a supply check valve, where it is heated to plus 21 ° С according to the norms, it is filtered through a filter and enters the stoic duct of the calculated cross-section passing from above down through all floors of this riser, then through the flow control valves from the total stoic duct, the estimated amount of supply air is taken into the room - the apartment, a duct heater is installed in the duct of the room - apartment, which heats the air to plus 70 ° С, thereby solving the issue of heat loss through the building envelope, control of the duct heater, and therefore the temperature regime in the room - apartment, is carried out from the control panel installed in each indoors - the apartment, with all this creates a positive balance of air pressure in the room - the apartment, which helps to remove stale air from the room - the apartment through the exhaust system entilyatsii consisting of the estimated exhaust duct passing through all floors of the building, the estimated exhaust fan, exhaust check valve picks up the exhaust air from each room - flats outside.

The invention is illustrated in the drawing, which shows a supply air circuit combined with air heating in a multi-story building.

Supply air ventilation unit - 1, supply air fan - 2, supply air check valve - 3, filter - 4, standoff duct - 5, flow control valves - 6, room - apartment - 7, room air duct - apartments - 8, duct heater - 9, building envelope - 10, control panel - 11, exhaust ventilation system - 12, design exhaust air duct - 13, design exhaust fan - 14, exhaust check valve - 15.

The method of supplying fresh air combined with air heating in a multi-storey building is as follows: supply air up to minus 40 ° С, according to the norms, enters the supply ventilation unit 1 from the top of the building using the calculated supply fan 2, the supply check valve 3, where it is heated to plus 21 ° С according to the norms, it is filtered through filter 4 (E-3 or E-5) and enters the stoikov duct 5 of the design cross-section, passing from top to bottom through all floors of this riser 5, then through the flow limit valves 6 from the total stoic duct 5, the calculated amount of supply air is taken into the room - the apartment, in the duct 8 of the room - apartment 7 a channel heater 9 (EK-600) is installed, which heats the air to plus 70 ° C, thereby solving the problem of heat loss through the building envelope of building 10, the control of the channel heater 9, and therefore the temperature in the room - apartment 7, is done from the control panel 11 (SATeP-03) installed in each room - apartment 7, and at the same time creates a positive balance of air pressure in the room - apartment 7, which helps to remove stale air from the room - apartment 7 through an exhaust ventilation system 12, consisting of a calculated exhaust duct 13, passing through all floors of the building, a calculated exhaust fan 14, exhaust check valve 15, taking the exhaust air from each room - apartment 7 to the street.

The method of supplying fresh air combined with air heating in a multi-story building has the following advantages:

- a person at any time of the year, regardless of weather conditions, has the opportunity to receive fresh air in accordance with the standards;

- each person, in his apartment, has the ability to independently regulate and set the optimal temperature for the room using the remote control;

- automation of the air flow at its temperature in accordance with established standards;

- there is no need to open the windows, which means that there are no drafts and, therefore, colds;

- significant air filtration in the supply system;

- high performance indicators of the proposed system;

- due to the breakdown of one ventilation system into several systems, survivability is increased by an appropriate number of times;

- reduction of energy costs 4-5 times;

- due to the application of all this in the complex significant funds are saved on the supply networks of hot water for heating;

- high adaptability of the design and installation of this system, depending on the volume and specified technological parameters;

- lack of consequences in case of rupture of pipelines and radiators of the heating system;

- there is no need to do preventive work on water heating - drawing, draining water to check and repair the heating system;

- The operational warranty of this system is about 35 years.

Claims (1)

A method of supplying fresh air combined with air heating in a multi-story building, including combining ventilation and heating, characterized in that the supply air, according to the norms, flows from the top of the building, enters the supply ventilation unit using a calculated supply fan, a supply check valve, where it is heated to plus 21 ° С according to the norms, it is filtered through the filter and enters the stoikov duct of the design cross-section, passing from top to bottom through all floors of this riser, then h Through flow control valves, the calculated amount of supply air to the room — the apartment — is selected from the total stoic duct; a duct heater is installed in the duct of the room — the apartment heats the air to plus 70 ° С, thereby solving the issue of heat loss through the building envelope, controlling the duct heater, and consequently, the temperature regime in the room - the apartment, is made from the control panel installed in each room - the apartment, while all this creates the perfect balance of air pressure in the room - the apartment, which helps to remove stale air from the room - the apartment through an exhaust ventilation system, consisting of a calculated exhaust duct passing through all floors of the building, a calculated exhaust fan, exhaust check valve, taking exhaust air from each room - apartments on the street.
