SOLAR HEAT AND COLD SUPPLY SYSTEM Russian patent published in 2015 - IPC F24J2/42 

FIELD: heating.

SUBSTANCE: solar heat and cold supply system includes a southern air pipeline made from material that absorbs solar radiation and a northern air pipeline, which are both located on the corresponding sides of the building, a thermal accumulator forming together with the building floor and under-floor air pipeline interconnected with the southern air pipeline, as well as heat exchange and soil air pipelines located one above another under the thermal accumulator, the second one of which is provided with soil heat-conducting pipes; with that, in the thermal accumulator there arranged is a vortex tube; outlets of the under-floor and soil air pipelines are connected to a cold channel of the vortex tube; with that, the southern and the northern air pipelines are connected to atmosphere, and the heat exchanger is connected to the room, as well as the southern air pipeline is provided with a convergent nozzle that is installed outside the room and includes a swirler consisting of four plates; with that, at the inlet opening of the convergent nozzle on the inner surface there is a circular groove connected to a contamination removal device.

EFFECT: reduction of power consumption to a drive of a forced draft fan by cleaning of sucked atmospheric air from drop-shaped and solid particles.
