The lack of technical solutions are pollution by exhaust ventilation internal air environment around agricultural buildings, especially livestock farms, where, along with a finely divided solid and caliornia pollution are observed allocation fetid odors.
The technical problem of the invention is the provision of environmentally normalized area around the farms by cleaning ejected from the room by ventilation of indoor air in the environment by performing suck�his filter, installed on the heat exchange air duct, in the form of site cleanup, as separating fine particles of dirt, so eliminating specific to livestock farms smells.
The technical result is achieved in that system genitalgenital quality of air in buildings contains South, made of absorbing solar radiation material, and Northern air ducts that are located on respective sides of the building, heat accumulator, forming with the floor of the building underground duct which communicates with the South, and located under the heat accumulator one above the other heat exchangers and underground ducts, the first of which reported from the North, and the second is equipped with a ground heat pipes, the system is equipped posted in the heat accumulator of the vortex tube, an inlet communicated with the underground duct, a "cold" channel - space and "hot" - through the heat accumulator with a soil pipe, the outputs of the underground and ground lines connected to the "cold" channel of the vortex tube, and the place of their connection with a filter, while the southern and Northern air channels communicated with the atmosphere, and heat exchange with the room, while the heat exchange air duct provided with a suction filter which is installed in the room and made in the form of site clean indoor air and consists of coaxially United tapering diffuser with helical grooves on the inner surface, longitudinally placed from the inlet to its outlet and comprising a circular groove formed at the inlet to the tapering of the diffuser and connected with the collection of dirt expanding nozzle, which is placed in the drying device in the form of containers intended for the filling of absorbent material (absorbing odors) and covered with a mesh material with a profile that corresponds to the plot of the velocity of the intake air in an expanding nozzle.
Fig.1 is a diagram of the system of genitalgenital, Fig.2 - suction site clean indoor air, Fig.3 - the inner surface of the diffuser with curved grooves.
The system contains air ducts: South 1, underground 2, North 3, heat exchanger 4 and base 5 with unpaved heat-conducting pipes 6, room 7, which is located under the heat accumulator 8, the vortex tube 9 to the input 10 to the processed air channel "cold" stream 11, which is connected to the input 12 of the filter 13, and the channel hot stream 14 is connected to ground duct 5, the filter 13 as its output 15 is connected with the inner volume of the space 7, the blower fan 16, mounted in the vent chamber 17 and the connected underground duct 2 through the dampers 18 and 19 to the input 10 of the vortex tubes� 9 and the output 12 of the filter 13, exhaust fan 20 mounted in the vent chamber 21 and coupled heat transfer duct with North duct conducting air from the space 7 into the atmosphere.
Heat exchanger 4, the air duct is equipped with an ejector 22 which is mounted in the space 7 and is in the form of site clean indoor air 23 premises 7. Site cleanup internal air 23 is coaxially from the United narrowing of the diffuser 24 with helical grooves 25 on the inner surface 26 and is longitudinally spaced from the inlet 27 to the outlet 28. Helical grooves 25 are connected with a circular groove 29, is made at the inlet 27 and connected with the collection of dirt 30 and an expanding nozzle 31. In an expanding nozzle 31 posted absorbing odors device 32 in the container 33 is aimed at filling the absorbing odors substance 34 is covered with a mesh material 35 with a profile that corresponds to the plot of the velocity of the intake air in an expanding nozzle 31.
System genitalgenital with quality of air in buildings is as follows.
It is known that indoor 7 agricultural buildings, such as poultry farms, cattle farms, pig farms, along with a finely divided solid and kaplonski downld�Znaniye allocated specific fetid smell, which significantly reduces the regulatory environmental parameters ambient air. Therefore, indoors 7 on heat transfer pipe 4 is mounted suction filter 22, and the inner air inhaled by the fan 20, enters through the inlet 27 of the tapered diffuser 24, where, moving along the helical grooves 25 in the direction of the outlet opening 28, swirls, and suspended solid particulate and droplet particles discarded centrifugal force to the inner surface 26. In the internal cavities of the helical grooves 25 to fine particulate and droplet particles collide, amalgamated, coagulate and under increasing pressure of the moving air stream is moved from the output (smaller) hole 28 to the input (more) hole 27, where fall under the influence of gravitational forces in a circular recess 29 and accumulate in the collection of dirt 30 where removed manually or automatically (not shown).
The purified solid particulate and droplet particles inside the air space 7 enters the flared nozzle 31. As a result of the sudden widening of moving from the diffuser 24 internal air it loses speed, and moving laminar flow contact with an absorbing odors substance 34, sequentially passing through with�tcity material 35, forming the receptacle 33. The laminar velocity profile of a moving flow of internal air at the approach to the outlet of an expanding nozzle 31 is characterized by a change of speed in all its points, with a maximum absolute value of the accounts for the axial component. Therefore, the volume of the substance 34 odor absorber in the device 32 in the container 33 is selected so as to ensure effective absorption of odor at a speed axial flow. However, the filling device 32 which absorbs odors substance 34 of the calculation of the maximum speed (as is customary according to known methods for devices that absorb odors) laminar axial component of the driving of the internal air in an expanding nozzle 31 leads to irrational process of absorption of odors and increase the overall hydraulic resistance of the site clean indoor air 22. This leads to additional energy consumption (higher power exhaust fan 20) and involuntary consumption of odor absorber. It is therefore proposed that the device 32, objemail which is modified to perform as a container 33 and is covered with a mesh material 35 with a profile that corresponds to the plot of the velocity of the moving stream sucked from the room 7 indoor air. The mass of the absorbing odors substance 34 is selected experiment�about depending on the volume of the space 7 and the number of odor emitting units animals, as well as the possibility of frequency demolition and replacement, for example when backing connection with expanding nozzle 31 of the container 33. The liquid 34 (for example silica gel KSM-5) can be replaced as new and subjected to regeneration.
In the warmer months when ambient air temperatures above the temperature values provided by the parameters of microclimate indoors 7, for example 25°C (air intake valve 19 is closed), the air southern air duct 1 is pumped into an underground duct 2 by the fan 16 mounted in the vent chamber 17. From an underground duct 2 to open the air flap 18 of atmospheric air under pressure is fed to the input 10 of the vortex tube 9, in which the bundle of "cold" (lower temperature of the incoming vortex in a pipe of atmospheric air) and hot (temperature above are some of the incoming vortex in a pipe of atmospheric air) air flows. Cold stream is separated in the vortex tube 9 of atmospheric air with specified under the terms of the microclimate inside the building 7 temperature, for example, 18°C on the cold channel 11 of the vortex tube 9 is supplied to the input 12 and the filter 13, where it is cleaned of solid particles and liquid particles from condensing in the process of cooling the vaporous moisture, atmospheregood, as you know, the higher the temperature of the atmospheric air, the more moisture in it, while the separated impurities in the filter 13 are removed from it through the installation of removing contaminants, such as float type steam trap. Hot flow of atmospheric air hot channel 14 of the vortex tube 9 is directed into an underground duct 5, where it is cooled, giving heat to the ground, and condensed in the cooling process air moisture is removed via a heat-conducting pipe 6 and is drained into the ground. Chilled in a soil air duct 5, the air is supplied to the input 12 of the filter 13, where it is purged from cameleopard contaminants and particulate contaminants, i.e. brought to the parameters specified by the microclimate in the room 7. From the filter 13 of the treated air with preset parameters for temperature, humidity and purity of solid particles is supplied into the room 7.
The air from the room 7 fan 20 mounted in the vent chamber 21 is directed into the heat exchange air duct 4, which gives off heat to the battery 8 and the Northern air duct 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 separation processing�already listed atmospheric air on "cold" and "hot" threads.
As a result the heat accumulator 8 accumulates thermal energy as heat from the air duct 4 and the housing of the vortex tube 9.
When the temperature is drawn by the fan 16 atmospheric air below gastropanel for given conditions of the microclimate of the building 7, for example at 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 damper 19 is supplied to the filter 13, where it is purified to set the terms of the microclimate in the premises of the 7 parameters. The heat accumulator 8 gives off heat to the intake air in underground duct 2, heating it to the required temperature. If thermal energy is given to the heat accumulator 8 atmospheric air moving through the underground duct 2, is not enough, it is heated by the heating system (not shown), the cost of which will be reduced since a significant portion of the heat is supplied from the heat accumulator 8 and the ground.
The placement of the filter 13 after the vortex tube 9 in the heat accumulator 8 reduces the consumption of cleaning drawn by the fan 16 through the South 1 duct, ambient air inside the premises 7 due to the partial purification � the process of separation of the processed air (part of solid contaminants is moved into the hot stream and drains in the ground heat exchanger tubes 6). As well as the heat generated from the battery 8 at low temperatures eliminates the possibility of the freezing of the filter elements, resulting in an increase in hydraulic resistance at temperatures of atmospheric air having a value substantially lower than the parameters of microclimate indoors 7, vortex tube 9 air damper 18 is disconnected from the underground duct 2. The suction of atmospheric air is heated as in the southern duct 1 through the use of heat of solar radiation (southern air 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 air that is blown inside the premises 7 applies a heating system (not shown) minor power.
As a result, the invention enables the use of solar energy and storage properties of the soil at both positive and negative temperatures of atmospheric air, thereby reducing the energy costs of the process of obtaining the specified parameters of microclimate indoors as the temperature and the separation of odors, as well as the degree of cleaning of ventilation air from pollution in�de particulate and droplet contamination.
The originality of the proposed technical solution is that the achievement of ecologically normalized environmental parameters around agricultural buildings, especially cattle farms and poultry farms, ensures a quality of air in the room due to the clean indoor air as fine particulate and droplet particles and fetid odors by setting the heat-exchange tubing inside the suction filter is in the form of site cleanup and odor absorber, representing coaxially United tapering diffuser and the divergent nozzle with a capacity for absorbing odors, substances with profileobject corresponding plot of the moving speeds of the processed stream.

SUBSTANCE: the temperature condition in dwelling houses and production areas is maintained by circulation of air blown through by an air intake through a heat exchanger, a heated or cooled down working medium circulates inside it, and supplied through air conduits to the room to be heated/ cooled. The circulating air is saturated by a fine-dispersed liquid or by its vapors. Air supply is accomplished into the heating/ cooling panels with heat conducting walls forming a closed circulation system jointly with the air ducts, heat exchanger and air intake. The fine-dispersed liquid and condensed vapors are moved through the narrow ducts of the panels with the aid of the velocity head of the circulating air. The device for maintenance of the temperature condition in dwelling hoses and production areas is also described.
EFFECT: prevented or reduced forced air circulation in the room, enhanced share of the radiant component of heating or cooling, and prevented reduction of the relative air humidity in the room at its cooling.

FIELD: heat-power engineering; heating systems; water heating systems, public services, agricultural sector and transport facilities.
SUBSTANCE: steam from electric steam generator is delivered to jet apparatus nozzle where it is mixed with cold liquid flow for forming two-phase flow at acceleration to supersonic velocity. At mixing chamber outlet, this two-phase flow is decelerated for forming shock wave and converting the flow into liquid flow after shock wave. Then, flow is divided and one part is directed to heat exchanger of vortex tube where it is heated and directed for replenishment of electric steam generator. Other part is directed to nozzle apparatus where it is accelerated to supersonic velocity for forming two-phase flow, after which it is decelerated for converting it into liquid flow saturated with micro-bubble component. Nozzle apparatus outlet is connected with swirler inlet where vortex flow is formed; from swirler, flow is directed to vortex tube where heat is released and flow is divided into hot and cold components. From vortex tube, flow is directed to heat exchanger for transfer of heat to second loop; cooled liquid flow is directed to ejector inlet.
EFFECT: enhanced efficiency of plant.
