The invention relates to a power system and is designed to maintain comfortable humidity levels in low-rise buildings, predominantly on livestock farms.

The disadvantage of this system is the inability to maintain the microclimate inside the building as the temperature and purity of atmospheric air from pollution in the form of solid and droplet particles having a varied composition, with changing climatic conditions.

Known system genitalgenital (see USSR author's certificate No. 1733871, CL F24J 2/42, 1992, bull. No. 18); containing South, made of absorbing solar radiation material, and Northern air ducts that are located on respective sides of the building, thermal BATT�knob, forming the floors of the building underground duct communicated with the South, and located under the heat accumulator one above the other heat exchangers and underground ducts, the first of which is communicated with the North, and the second is equipped with a ground heat-conducting pipes, the system is equipped with placed in the heat accumulator of the vortex tube, an inlet communicated with the underground duct, a "cold" channel - with the room, and the "hot" - through the heat accumulator with a soil pipe, exits the underground and ground lines connected to the "cold" channel of the vortex tube, and the place of their connection with a filter the southern and Northern air ducts are communicated with the atmosphere, and heat exchange with the room.

The disadvantage of this technical solution is the intensity with changing climatic conditions, when for the South duct blower fan comes particulate pollution in the form of droplets of moisture and particulate matter, which can't be moved by the fan drive requires extra energy (see, for example, Korchagin A. G., etc. Saving heat and electricity. M.: 1980, 280 p., ill.). In addition, and solid contaminant particles, such as atmospheric and/or technological dust, and intensify�nose moving parts of the fan.

The technical task of the invention is to reduce energy consumption for the drive of blower by cleaning the intake of atmospheric air from the droplet and solid particle when it passes through a tapered nozzle, mounted on the South entrance to the duct and including a swirler device and removing contaminants, coupled with a circular groove located at the entrance of the tapered nozzle.

The technical result is achieved in that the system genitalgenital containing South, made of absorbing solar radiation material, and Northern air ducts that are located on respective sides of the building, the heat accumulator forming the floors of the building underground duct communicated with the South, and located under the heat accumulator one above the other heat exchangers and underground ducts, the first of which is communicated with the North, and the second is equipped with a ground heat-conducting pipes, the system is equipped with placed in the heat accumulator of the vortex tube, an inlet communicated with the underground duct, a "cold" channel - space and the "hot" - through the heat accumulator with a soil pipe, exits the underground and ground lines connected to the "cold" channel of the vortex tube, and W� venue connecting them with a filter the southern and Northern air ducts are communicated with the atmosphere, and the heat exchanger - room, while the South duct is provided with a tapered nozzle, which is installed outdoors and is made with the swirler, consisting of four plates, the input and output sections which are located one relative to another at a right angle, and the inlet tapered nozzle on the inner surface is made of a circular groove connected with a device for removal of contaminants.

Fig.1 is a diagram of the system of genitalgenital, Fig.2 - swirl tapered nozzle at the South entrance to the duct.

The system contains ductwork: South 1, underground 2, North 3, heat exchanger 4 and soil 5 with unpaved heat-conducting tubes 6, room 7, which is located under the heat accumulator 8, the vortex tube 9 with an inlet 10 for the treated air of the channel "cold" stream 11 connected to the inlet 12 of the filter 13 and the channel hot stream 14 is connected to ground duct 5, the filter 13 to its outlet 15 is connected with the internal volume of the space 7, the blower fan 16, mounted in the vent chamber 17 and connected underground duct 2 through the air dampers 18 and 19 to the input 10 of the vortex tube 9 and the output 12 of the filter 13, the exhaust fan 20, �chain in the ventilation chamber 21 and coupled heat exchanger 4 with duct North duct 3, performing the ejection of air from the space 7 into the atmosphere.

South duct 1 is provided with a tapered nozzle 22, which is installed outdoors 7 and made a swirler 23, consisting of four 24, 25, 26 and 27 plates, input 28, 29, 30, 31 and output 32, 33, 34 and 35 sites are located relative to one another at right angles. At the inlet 36 of the tapered nozzle 22 on the inner surface 37 is made of a circular groove 38, connected to the device removing contaminants 39.

System genitalgenital operates as follows.

In the presence of a droplet of atmospheric particles and process water, and solid particles of dust in the atmospheric air entering via the southern 1 through the air duct underground duct 2 into the discharge fan 16, his drive additional energy is expended to transport the mixture to the input 10 of the vortex tube 9. In addition, the air pollution intensify the wear of the blades of blower 16 and, consequently, decreases the reliability of the system genitalgenital. Supply 1 South duct tapering nozzle 22 with the swirler 23 causes the air with particles of dirt after the inlet opening 36 is in contact with the input sections 28, 29, 30, 31 four plates 24, 25, 26 and 27 are rotated at a right angle relative output sections 32, 33, 34 and 35. As a result of the intake of atmospheric air in a tapered nozzle is divided into four streams, and as the motion is moved by 90°, which leads before entering it in the South duct 1 into a rotary motion. Under the action of centrifugal forces to outdoor air pollution, contaminants are discarded to the inner surface 37 of the tapered nozzle 22 toward the circular groove 38 at the inlet 36; how do you get into the device remove contaminants 39 for removal, either manually or automatically (Fig. not shown).

Consequently, the blower fan 16 is supplied free of contamination of atmospheric air and drive it consumes the normalized amount of energy regardless of weather-climatic conditions of the system genitalgenital.

In the warmer months when temperatures above the temperature values provided by the parameters of the microclimate inside the building 7, for example, 25°C (air intake valve 19 is closed), the air for the South duct 1 is blown into an underground air duct 2 fan 16 mounted in the vent chamber 17. From underground duct 2 to the air flap is open 18 atmospheric air under pressure is fed to the input 10 vortices�eve of the pipe 9, in which stratify on "cold" (temperature slightly below the vortex of the incoming atmospheric air pipe) and hot (the temperature slightly above the vortex of the incoming atmospheric air pipe) air flows. Cold stream is separated in a vortex tube 9 of atmospheric air with a given under the terms of the microclimate inside the building 7 temperature, e.g. 18°C on the cold channel 11 of the vortex tube 9 is fed to the input 12 and the filter 13, where it is cleaned of solid particles and liquid particles from the condensed during the cooling process, moisture vapor atmospheric air, as is well known, the higher the temperature of the atmospheric air, the more moisture in it, while the separated impurities in the filter 13 is removed from it through the installation of removing contaminants, such as steam trap float type. Hot flow of atmospheric air hot channel 14 of the vortex tube 9 is directed into an underground air pipe 5, where it is cooled, giving heat to the ground, and condensed in the cooling process of the air the moisture is removed via a heat-conducting pipe 6 and is drained into the soil. Chilled in a soil air duct 5, the air supplied to the inlet 12 of the filter 13, where it is purged from catalinabase contaminants and particulate contaminants, i.e. brought to paramé�ditch determined by a given microclimate in the room 7. From the filter 13 of the treated air with the given parameters of temperature, humidity and degree of purification from solid particles is supplied into the room 7.

The air from the room 7 fan 20 mounted in the vent chamber 21 is directed in heat exchange duct 4, where it gives off heat to the battery 8, and the Northern air pipe 3 is discharged into the atmosphere.

The placement of the vortex tube 9 in the heat accumulator 8 provides additional accumulation of heat through the housing of the vortex tube 9, in the process of delaminating the processed ambient air at "cold" and "hot" threads.

As a result of the heat accumulator 8 accumulates thermal energy as heat from the duct 4 and the housing of the vortex tube 9.

When the temperature is drawn by the fan 16 of atmospheric air below gastropanel for given conditions of the microclimate of the building 7, for example in night time temperature is about 15°C, opens the air intake valve 19 (air flap 18 is closed). Atmospheric air for the South duct 1 by the fan 16 through the open air valve 19 is supplied to the filter 13, where it is purified to the specified conditions of the microclimate in the premises of the 7 parameters. The heat accumulator 8 of the ICA gives off heat�yuemao ambient air in underground duct 2, heating it to the required temperature. If thermal energy given to the heat accumulator 8 atmospheric air moving through the underground duct 2, it is not enough, it is heated by the heating system (not shown), the costs of which will be reduced since a significant portion of heat supplied from the heat accumulator 8 and ground.

The placement of the filter 13 after the vortex tube 9 in the heat accumulator 8 reduces the cleaning intensity drawn by the fan 16 through the southern 1 duct, ambient air inside the premises 7 due to partial clearing in the process of delaminating the processed air (part of solid contaminants is moved into the hot stream and drains in the ground heat exchanger pipes 6). Also the heat generated from the battery 8 at low temperatures of atmospheric air eliminates the possibility of the freezing of the filter elements, resulting in an increase in hydraulic resistance at temperatures of ambient air, having a value substantially lower than the parameters of the microclimate inside the building 7, the vortex tube 9 air damper 18 is disconnected from the underground duct 2. The intake of atmospheric air is heated as in the South duct 1 through the use of solar heat well defined spatial radiation viewing�and (South the duct is made of absorbing solar radiation material) and from the heat accumulator 8 in underground duct 2. In case of lack of heat to obtain the desired temperature of the air that is blown inside the premises 7, apply a heating system (not shown) low power.

As a result, the invention allows the use of solar energy and storage properties of the soil at both positive and negative temperatures of ambient air, thereby reducing energy consumption of the process of obtaining the specified parameters of the microclimate indoors as the temperature and purity of the ventilated air from pollution in the form of solid and droplet contamination.

The originality of the proposed technical solution is that the maintenance of normalized energy consumption for the drive of blower and reliable operation under changing climatic impacts of system genitalgenital generally achieved by purging the atmospheric intake air from the droplet and particulate matter by supplying the South entrance of the duct tapering nozzle with swirler inside it, which consists of four plates, the input and output sections which are located one relative to another at a right angle, and the input advertisehere nozzle on the inner surface is made of a circular groove, connected to the device for removal of contaminants.

System genitalgenital containing South, made of absorbing solar radiation material, and Northern air ducts that are located on respective sides of the building, the heat accumulator forming the floors of the building underground duct communicated with the South, and located under the heat accumulator one above the other heat exchangers and underground ducts, the first of which is communicated with the North, and the second is equipped with a ground heat-conducting pipes, the system is equipped with placed in the heat accumulator of the vortex tube, an inlet communicated with the underground duct, a "cold" channel - space and the "hot" - through the heat accumulator with a soil pipe, exits the underground and ground lines connected to the "cold" channel of the vortex tube, and the place of their connection with a filter, with the southern and Northern air ducts are communicated with the atmosphere, and heat exchange with the room, characterized in that the South duct is provided with a tapered nozzle, which is installed outdoors and is made with the swirler, consisting of four plates, the input and output sections are arranged relative to one another at right angles, moreover, the inlet Suzi�of ashegoda nozzle on the inner surface is made of a circular groove, connected to the device for removal of contaminants.
