FIELD: ventilation and air heating industry.

SUBSTANCE: invention relates to aerodynamic ventilation and heating systems. According to proposed method, air gets through intake pipe into mixing chamber with for mixing with recirculated air and then delivery fan feeds air into heating chamber where air is heated to normal temperature and then air passes into common supply air duct where t-pipe is installed before output to room. Distributing device adjusted by aerodynamic properties is installed in said t-pipe. Said distributing devices provides delivery of preset amount of air into room. Further on, distributing device arranged in t-pipe takes in air from room and directs it into common exhaust air duct which directs air to exhaust fan after which distributing valve is installed which directs air outside through exhaust pipe and for recirculation into recirculation air duct.

The invention relates to the heating and ventilation industry, and in particular to systems of aerodynamic heating and ventilation.

The known method, including fresh air and the hood exhaust air from the room (Air heating. http://archive.domsovet.ru/goods/105.html 2006).

The disadvantage of this method is the inability to precisely adjust the distribution of the fresh air circulation, increase the pressure of the supply air, leading to higher power fans, increase noise, which leads to higher costs for sound insulation, extra controllers (anemostat) air flow, which leads to the appreciation of the estimated cost.

The known method, adopted as a prototype, including fresh air and the hood exhaust air from the premises (heating, ventilation and air conditioning. Part 1, 28.01.2005. DEVELOPED by the Federal state unitary enterprise "Santechniiproekt" with the participation of the Federal state unitary enterprise "Center methodology, regulation and standardization in construction" (FSUE CNS) and the group of experts. ADOPTED AND PUT INTO EFFECT from 01.01.2004 resolution of Gosstroy of Russia dated June 26, 2003, No. 115. http://www.gvozdik.ru/documents/4017.html: heating, ventilation and air conditioning. Part 2, 31.01.2005. http://www.gvozdik.ru/documents/4023.htm).

The disadvantage of this method is the inability to precisely adjust the distribution of the fresh air circulation, increase the pressure of the supply air, leading to higher power fans, increase noise, which leads to higher costs for sound insulation, extra controllers (anemostat) air flow, which leads to the appreciation of the estimated cost.

The present invention is to create a system with more accurate submission of required volume of air at a given location, according to the project, the efficiency of this method, the simplification of the structure for implementing the inventive method.

The problem is solved due to the fact that the aerodynamic distribution of air flows in ventilation and air heating includes fresh air and the hood exhaust air from the room, while the new is that the air enters through intake pipe into the mixing chamber with recirculation air, next intake fan delivers air to the heating chamber where it is heated to the norm in the future, the air supplied to the common supply air duct, where before leaving the premises shall be established tee to exhaust air in the room, but this tee is installed adjustable aerodynamic properties of the distribution device, which will allow you to precisely apply the specified volume of air in the room in the future through the adjustable aerodynamic properties of the distribution device, placed at the tee, the air taken from the room in the common exhaust duct that delivers air to an exhaust fan, then you set the control valve, which sends the air to the outside through an exhaust pipe or recirculation in the recirculation duct.

The invention is illustrated in the drawing, which shows a diagram of the aerodynamic method of air distribution and ventilation air heating.

On the drawing, the intake pipe 1; a mixing chamber - 2; intake fan - 3; a heating chamber - 4; General feed duct - 5; t - 6; switchgear - 7 rooms - 8; General exhaust duct - 9; exhaust fan - 10; distribution valve 11; an exhaust pipe 12; the recirculation duct - 13.

Aerodynamic distribution of air flows in ventilation and air heating works as follows: air enters through intake pipe 1 into the mixing chamber 2 with recirculation air, next intake fan 3 takes the air into the heating chamber 4, where it is heated to the norm in the future, the air supplied to the common supply air duct 5, where is ur outlet in the room is installed tee 6 to exhaust air in the room, the tee set-adjustable aerodynamic properties of the distribution device 7, which will allow you to precisely apply the specified volume of air in the space 8, further through the adjustable aerodynamic properties of the distribution device 7 placed in the tee 6, the air taken from the room 8 in the common exhaust duct 9, which feeds air to an exhaust fan 10, then set the control valve 11, which sends the air to the outside through the exhaust pipe 12 or recirculation in the recirculation duct 13.

Aerodynamic distribution of air flows in ventilation and air heating has the following advantages:

1) use a less powerful fan - 30% less power than existing systems air distribution, since it is not necessary to set the valves, animosity, gates, etc.;

2) reduced noise level - up to 40%than in existing systems air distribution, as the motors in the present method is less powerful, the noise level is lower in the room, which, of course, better;

3) the installation of the ducts of one section is excluded fanout;

4) cost reduction - no Plenum, reducing the length of the ducts, all of this is near the e to the specified premises (instead of the basement and floors);

5) accurate submission of required air volume in the room that leads to a better climate in this area.

Aerodynamic distribution of air flows in ventilation and air heating, including fresh air and the hood exhaust air, wherein air flows through the intake pipe into the mixing chamber with recirculation air, next intake fan delivers air to the heating chamber where it is heated to the norm in the future, the air supplied to the common supply air duct, where before leaving the premises shall be established tee to exhaust air in the room, but this tee is installed adjustable aerodynamic properties of the distribution device, which will allow you to precisely apply the specified volume of air in the room in the future through adjustable aerodynamic properties of the distribution device, placed at the tee, the air taken from the room in the common exhaust duct that delivers air to an exhaust fan, then you set the control valve, which sends the air to the outside through an exhaust pipe or recirculation in the recirculation duct.
