The invention is intended to maintain a comfortable air parameters in low-rise buildings, mainly on livestock farms.

The disadvantage of this system is the inability to maintain the microclimate inside the building, as the temperature and purity of the atmospheric air from pollution in the form of a solid and drop-like particles with different composition under varying climatic conditions.

Known system genitalgenital (see USSR author's certificate No. 1733871, CL F24J 2/42, 1992, bull. No. 18), containing the South, made of absorbing solar radiation material, and the Northern air ducts located on the respective sides of the building, heat accumulator, forming with the floor of the building is underground I connector reported from the South, and located under thermal battery one above the other of the heat exchangers and underground lines, the first of which is in communication with the North, and the second equipped with a ground heat transfer pipes, the system is equipped with placed in thermal battery of the vortex tube inlet communicated with Underfloor duct, cold channel - room, and hot through heat accumulator with the ground connector outputs underground and ground lines connected to the "cold" channel of the vortex tube, and the place of their connection filter is installed, the southern and the Northern passage communicated with the atmosphere, and heat exchange with the environment.

Disadvantages technical solutions are additional costs caused by long-term operation in different temperature and humidity regimes of the soil, when widely varies not only soil temperature, but also humidity, which leads to rapid oxidation of the metal pipe and, accordingly, its dismantling, in addition, temperature effects there is considerable heat loss of the transported air.

The technical task of the invention is to maintain the rated life of the soil pipe and eliminate their heat loss during extended operation under varying temperature and humidity of the soil, acting on the elements of the system genitalgenital by performing layer of the soil pipe made of composite material with a fixed fine basalt, longitudinally stretched by the length between the metal base waterproofing.

The technical result is achieved by the fact that the system genitalgenital containing the South, made of absorbing solar radiation material, and the Northern air ducts located on the respective sides of the building, heat accumulator, forming with the floor of the building underground duct communicated with the South, and located under thermal battery one above the other of the heat exchangers and underground lines, the first of which is in communication with the North, and the second equipped with a ground heat transfer pipes, the system is equipped with placed in thermal battery of the vortex tube inlet communicated with Underfloor duct, cold channel - space and "hot" - through thermal battery ground connector outputs underground and ground lines connected to the "cold" channel of the vortex tube, and the place of their connection filter is installed, the southern and the Northern passage communicated with the atmosphere, and heat exchange with the room, with a dirt of Vozduha the water (pipe) made of composite material, which includes a metal base, heat-insulating and heat-retaining of fine basalt and waterproofing, and fine-fibrous basalt longitudinally located in the extended position along the length of the soil pipe and fixed in the water between the metal substrate and waterproofing.

The figure 1 presents the diagram of the system of genitalgenital, figure 2 - section of an element of an underground pipeline.

The system contains the lines: South 1, underground 2, North 3, heat exchanger 4, and clay 5 with ground heat transfer tubes 6, room 7, which is heat accumulator 8, a vortex tube 9 input 10 for the processing air channel "cold" stream 11 that is connected to the input 12, the filter 13, and channel hot stream 14 that is connected to ground duct 5, the filter 13 and the output 15 is connected with the internal volume of space 7, the discharge fan 16, installed in the Plenum 17 and connected underground duct 2 through the damper 18 and 19 to the input 10 of the vortex tube 9 and 12 filter 13, the exhaust fan 20 mounted in the vent chamber 21 and connected to the heat exchange duct with the North duct which release air from room 7 to the atmosphere.

Dirt, battery, speaker, buzzer is 5 made of a composite material and includes a metal base 22, heat-insulating and heat-retaining layer 23 of fine basalt 24, located longitudinally along the length of soil pipe 5, and waterproofing 25.

System genitalgenital works as follows.

Especially in autumn-winter and winter-spring periods of the year the temperature-vlajnosti modes of soils significantly change not only daily, but also during the day (see, for example, Handbook of the climate of the USSR, Issue 28. Humidity, precipitation, snow cover. Gidrometeoizdat. Leningrad, 1968 - 259 C. Il.), which contributes to the intensification of the process of oxidation of metallic underground piping 5 and increase of heat moving it flow hot air from the vortex tube 9 with the values of temperature, different from the normalized space 7 (see, for example, SNiP II-3-79. Building physics, M.: 1998 - 12 C.). While coming into the room 7 after the air filter 13 does not provide the specified parameters of the microclimate, and the metal base pipe 5 is covered on the outside with rust and scale, i.e. intensely wear that requires disassembly work on its replacement, and this leads to additional energy consumption during operation of the system genitalgenital.

Perform a soil pipe 5 from the composition of the mother of the La location along its length fine basalt 24 and subsequent placement between the metal base 22 and waterproofing 25 causes in the process of heat transfer from the hot stream from the vortex tube 9 by conduction through the metal base 22, it is accumulated on the thickness of the layer 23 of fine basalt 24 (see, for example, Fibrous materials from basalts of Ukraine. Publishing House "Technika". Kyiv. 1971 - 76 C., Il.). As a result of turnover heat accumulating layer 23 of fine basalt 24 from the hot stream is cooled and sent through the filter 13 in room 7, supported on the set microclimate.

Upon receipt of the vortex tube 9 hot air stream with a temperature below normalized to room 7 in the earthen pipe 5 is heat extraction from fine basalt 24 to the entire length of the heat storage layer 23, which is also acting as a thermal insulation prevents heat loss into the ground. Heated due to the accumulated heat of fine basalt 24, longitudinally located on the heat storage layer 23 of a soil pipe 5, a hot stream from the vortex tube 9 through the filter 13 is supplied to the space 7, while maintaining the specified climate. Consequently, the presence of heat-insulating and heat-retaining layer 23 maintains a given microclimate 7 when the temperature changes of the atmospheric air entering the vortex tube dla thermodynamic stratification on "hot" and "cold" streams without additional energy consumption for temperature control air coming into the room 7, and the presence of waterproofing extends the life of the soil pipe 5 and supports the process of heat accumulation layer 22.

In the warmer months when the ambient air is above the temperature values provided by the parameters of the microclimate inside the building 7, for example, 25°C (air valve 19 is closed), the air on the South duct 1 is pumped into an underground duct 2 by the fan 16 mounted in the vent chamber 17. From underground duct 2 on the outdoor air damper 18 atmospheric air under pressure is fed to the input 10 of the vortex tube 9, in which the stripes on the "cold" temperature slightly below included in a vortex tube atmospheric air) and hot (temperature slightly higher than the incoming vortex tube atmospheric air) air flow. Cold stream is separated in the vortex tube 9 of atmospheric air with the specified conditions of the microclimate inside the building 7, for example, temperature, 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 from solid particles and liquid particles condensed during the cooling of the vaporous moisture atmospheric air, and, as you know, the higher the air temperature the more moisture, while the separated impurities in the filter 13 removes through the installation of removing contaminants, such as steam trap float type. "Hot flow of atmospheric air on the hot channel 14 of the vortex tube 9 is sent to a soil pipe 5 where it is cooled, giving heat to the ground, and condensed in the cooling process air moisture is removed through the heat-conducting pipe 6 and drains into the soil. Chilled in soil air duct 5, the air is supplied to the input 12, the filter 13, where is purged from cameleopard contaminants and particulate contaminants, i.e., brought to the parameters given by the microclimate in the premises 7. From the filter 13 air treated with the given parameters on temperature, humidity and purity of solid particles is supplied into the room 7.

The air from the space 7 by the fan 20 mounted in the vent chamber 21, is directed in heat exchange duct 4, which gives off heat to the battery 8, and on the North duct 3 is discharged into the atmosphere.

The placement of the vortex tube 9 in thermal battery 8 provides additional accumulation of heat dissipated through the housing of the vortex tube 9, in the process of separation of the processed ambient air on "cold" and "hot" threads.

The result is aloway battery 8 accumulates thermal energy, coming from the heat exchange air duct 4 and the housing of the vortex tube 9.

By reducing the temperature of the blowing fan 16 atmospheric air below gastropanel for the given conditions of the microclimate of the building 7, for example at night time temperature is about 15°C, opens the air valve 19 (air valve 18 is closed). Atmospheric air for the South duct 1 by the fan 16 through the open air damper 19 is fed to the filter 13, where it is cleaned to the specified conditions of the microclimate in the premises of the 7 parameters. Heat accumulator 8 gives off heat the intake air in the underground duct 2, heating it to the required temperature. If thermal energy given to thermal accumulator 8 atmospheric air, moving along 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 heat supplied from the heat accumulator 8 and the ground.

Placement of the filter 13 after the vortex tube 9 in thermal battery 8 provides a reduction in the energy intensity of cleaning blowing fan 16 through the southern 1 intake of atmospheric air inside the premises 7 due to partial purification in the process of separation of the processed air (part solid pollution which moves in response to a hot flow and drains into the soil by heat exchange tubes 6). And the heat from the battery 8 at low temperatures of atmospheric air eliminates the possibility of the freezing of the filter elements, resulting in increased flow resistance at temperatures of atmospheric air having a value substantially lower than the parameters of the microclimate inside the building 7, vortex tube 9 air flap 18 is disconnected from underground duct 2. The intake air is heated as in the South duct 1 through the use of heat of solar radiation (southern duct made of absorbing solar radiation material), and from the heat accumulator 8 in underground duct 2. In case of lack of this heat to produce the desired temperature of the air pumped into the space 7, is applied heating system (not shown) minor power.

The proposed invention allows the use of solar energy and accumulating properties of the soil, both positive and negative temperatures of atmospheric air, ensuring reduced energy consumption of the process of obtaining the given parameters of the microclimate indoors as the temperature and degree of purification of the ventilated air from pollution in the form of solid and caplehorn what's dirt.

The originality of the proposed technical solution is that the energy consumption reduction during long-term operation of the system genitalgenital, is achieved by providing standard life underground pipeline without additional dismantling under varying temperature vlajnosti modes of the soil, and maintaining a specified indoor climate, by performing a soil pipe made of composite material including fine basalt enclosed between the metal base and waterproofing. Thus the performance of fine basalt as a layer with a longitudinally stretched fibers along the length of soil pipe allows not only to perform the function of thermal insulation, but also to accumulate heat transferred by conduction through the metal base from moving hot air stream, and this is in addition to eliminate heat loss through waterproofing accumulating in the environment-soil helps to keep the consistency of a given microclimate in the premises without any additional power consumption when the temperature of the atmospheric air entering the vortex tube.

System genitalgenital containing the South, made of absorbing solar radiation material, and the Northern air the wires, located on respective sides of the building, heat accumulator, forming with the floor of the building underground duct communicated with the South, and located under thermal battery one above the other of the heat exchangers and underground lines, the first of which is in communication with the North, and the second equipped with a ground heat transfer pipes, the system is equipped with placed in thermal battery of the vortex tube inlet communicated with Underfloor duct, cold channel - room, and hot through heat accumulator with the ground connector outputs underground and ground lines connected to the "cold" channel of the vortex tube, and for a place of their connection filter is installed, the southern and the Northern passage communicated with the atmosphere, and heat exchange with the location, wherein the ground connector is made of a composite material that includes a metal base, heat-insulating and heat-retaining of fine basalt and waterproofing, and fine-fibrous basalt longitudinally located in the extended position along the length of the soil pipe and fixed in a layer between the metal substrate and waterproofing.

SUBSTANCE: sun power plant intends for conversing solar energy to thermal energy for using thermal energy for domestic appliances. Hot water supply sun power plant has at least one solar battery made of thermal collectors in form heat-insulated flat box-shaped cases. Top flat light-transparent panels are disposed in perpendicular to direction of sun light. Light-transparent panels are disposed above membranes-absorbers which absorb solar radiation. Membranes-absorbers are provided with temperature transducers. Membranes-absorbers have parallel lateral metal pipes for liquid heat carrier. Pipes are connected together in any membrane-absorber by longitudinal tubular collectors. Collectors are connected together by branches in series through drive stop valves which are connected to pipeline of water discharge of warmed liquid heat carrier which is connected with top area of heat-accumulating container. Lower area of container is connected with longitudinal tubular collector of membrane-absorber of one of end heat collector by means pipeline for supplying cooled liquid heat carrier through circulation pump. Heat water supply and heating system heat exchangers are disposed at top area of heat-collecting container one above another. Heat exchangers are connected with central heating system pipeline and with pipeline for supplying warmed running water. Program electron unit of the plant is connected with temperature transducers of membranes-absorbers, which unit controls operation of thermal transducers, circulation pump electric motor and drives of stop valves. Sun power plant is provided with heat-proof heat-accumulating members that are disposed uniformly in lower area of heat-accumulating container. Heat-accumulating members are filled with liquid having positive solidification temperature. Program electron unit is provided with mechanisms for tracking perpendicularity of solar energy to surface of top light-transparent panels of thermal collectors. Heat-insulated flat box-shaped cases of collectors are made for rotation around horizontal axes disposed at two mutually perpendicular vertical planes. Any membrane-absorber is made in form of thin-walled metal plate with gofers which embrace parallel lateral metal pipes for liquid heat carrier. Space V of heat-insulated working cavity of heat-accumulating container exceeds total space Vtot of cavities of membranes-absorbers of heat collectors for liquid heat carrier, space V1 of hot water heat exchanger for domestic appliances, space V2 of heating system heat exchanger and total space Vh-am of heat-collecting member for 50-400, 100-120, 20-30 and 10-20 times correspondingly. Total area Stot of external surfaces of the heat exchangers is 3-8 times larger than areas Sm of top surfaces of rigid membranes-absorbers. Solidification temperature T of liquid which fills heat-proof heat-accumulating members equals to 35-600C.

EFFECT: improved efficiency of heating process; lower speed of heat carrier cooling.
