SYSTEM OF HELIO-THERMO-COLD SUPPLY Russian patent published in 2014 - IPC F24J2/42 

FIELD: heating.

SUBSTANCE: invention is intended to maintain the comfort of air parameters in low-rise buildings, mainly on livestock farms. The system of helio-thermo-cold supply comprises the southern, made of the material absorbing solar radiation, and northern air ducts located on respective sides of the building, the heat accumulator which forms with the floor of the building the underground air duct which communicates with the southern, as well as located under the heat accumulator one above the other heat exchanging and ground air ducts the first of which communicates with the northern, and the other is provided with the ground heat-conducting tubes, and the system is equipped with a vortex tube located in the heat accumulator, communicated with its inlet to the underground air duct, with the cold duct - with the room, and hot - through the heat accumulator to the ground air duct, the outputs of the underground and the ground air ducts are connected to the cold duct of the vortex tube, and behind the place of their connection the filter is mounted, and the southern and northern air ducts are communicated with the atmosphere, and heat exchanger - with the room, and the system is equipped with a thermoelectric generator, made in the form of a housing and a set of differential thermocouples, and the passageway for hot coolant is located in the housing and the passageway for the cold coolant, moreover, the inlet pipe of the passageway for the hot coolant is connected by the channel of hot flow of the vortex tube, and with its outlet pipe - with the ground air duct, at that the inlet pipe of the passageway for the cold coolant is connected to the channel of the cold flow of the vortex tube, with its output pipe - to the room.

EFFECT: reducing the power consumption of the system of helio-thermo-cold supply by using the temperature difference of cold and hot flows of the vortex tube to generate electricity by the thermoelectric generator.
