The lack of technical solutions is the amount of energy systems, due to the need for more energy consumption on standby lighting in the dark, and provision of power supply circuits automated control and regulation of technological equipment.
The technical problem of the invention is to reduce the energy intensity of the system genitalgenital by using the temperature difference between cold and hot streams of the vortex tube for the generation of electric power by thermoelectric generator, vypolnen is in the form of a housing with two intercommunicating channels for hot and cold fluids, and the set of differential thermocouples.
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 - location, 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, the system is equipped with a thermoelectric generator made in the form of a body and set of differential thermocouples, and in case there is a passage for hot fluid and a passage for cold fluid, CR is IU, the inlet port for hot fluid is connected by a channel hot flow vortex tube, and weekends with his pipe - soil air duct, while the inlet port to the cold coolant is connected to channel "cold" flow vortex tube, weekends with his elbow - room.
The figure 1 presents the diagram of the system of genitalgenital, figure 2 - connection of the vortex tube with a thermoelectric generator.
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 mounted in the vent chamber 17 and connected underground duct 2 through the air valves 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 the Emesene 7 into the atmosphere.
Thermoelectric generator 22 is made in the form of housing 23 and the set of differential thermocouples 24 and the housing 23 are located a passage for hot carrier 25 with the inlet 26 and outlet 27 of the nozzle, and a passage for cold heat carrier 28 with the inlet 29 and outlet 30 of the nozzle. Inlet pipe 26 passing channel hot carrier 25 is connected to the channel hot thread 14 of the vortex tube 9, and the outlet pipe 27 - group air duct 5. The "hot" ends 31 of the set of differential thermocouples 24 fortified inside passages for hot carrier 25, and "cold" ends 32 fortified inside a flow channel for the cold fluid 28. The inlet 29 of the entry channel for the cold heat carrier 28 is connected to the cold flow channel 11 and the outlet pipe 30 through the filter 12 from location 7.
System genitalgenital works as follows.
It is known that in the vortex tube 9 is thermodynamic stratification of the air excess pressure or gas "hot" and "cold" streams with a temperature difference of more than 40°C (see, for example, Merkulov VP Vortex effect and its use in engineering. Samara, 1991 - 368 C.) between the channels of the hot stream 14 and a cold stream 11. Therefore, thermodynamically stratified "hot" the flow of atmospheric air from the vortex tube 9 by channel hot stream 14 flows through the inlet 26 in a passage for hot coolant 25, where contact with "hot" ends 31 of the set of differential thermocouples 24 and then is directed through the outlet 27 in the dirt duct 5. At the same time thermodynamically stratified cold flow of the atmospheric air flows from the vortex tube 9 by cold flow channel 11 through the inlet 29 in a passage for cold coolant 28, where in contact with "cold" ends 32 of the set of differential thermocouples 24 and then is directed through the outlet 30 into the inlet 12 of the filter 13.
As a result of contact hot thread with "hot" ends 31 of the set of differential thermocouples 24 and "cold" ends 32 with a "cold" flow on each element of the set of differential thermocouples 24 when used in the material of thermocouple, such as chromel-Copel, there is a thermo-EMF of 6.96 to mV (see, for example, Ivanov, G.M. Thermal measurements and instruments. M.: Energoatomizdat, 1984 - 230 C.). This allows you to receive the output voltage of thermoelectric generator 22 within 12-36 (see, for example. Technical fundamentals of heat. Thermal engineering experiment. Handbook / edited amended Vimsatika. M.: Energoatomizdat, 1980 - 560 C.), which is enough for the emergency lighting of premises and/or supply of automation and control systems genitalgenital that snijaete energy intensity.
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) atmospheric air for 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, 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 temperature of the atmospheric air, the more moisture, while the separated impurities in the filter 13 removes through the installation of removing contaminants, such as trap Pople who kovago 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.
In the heat accumulator 8 accumulates thermal energy coming from the heat exchange air duct 4 and the housing of the vortex tube 9.
When SN is hereto temperature of the blowing fan 16 atmospheric air below gastropanel for the given conditions of the microclimate of the building 7, for example during the 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 of the solid impurities moves into a hot stream 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 at 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 a solid and drop dirt.
The originality of the proposed technical solution is that the use of temperature differential between thermodynamically stratified "hot" and "cold" streams of atmospheric air in the vortex tube is advanced allows you to generate electrical energy, sufficient for emergency lighting and/or power automation and control systems genitalgenital that reduces its intensity.
