SOLAR POWER PLANT FOR HOT WATER SUPPLY AND SUN COLLECTOR OF SUCH PLANT Russian patent published in 2005 - IPC

FIELD: solar power engineering.

SUBSTANCE: solar power plant includes solar battery having at least two solar heat collector mutually joined through branch pipe. Said collectors are provided with individual heat pickups and individual pipelines for discharging hot water out of them through connection branch pipes. Shut-off devices are mounted in zones of crossing of branch pipes and pipelines. Pipeline for supplying water from accumulating tank to solar battery includes water pump; accumulating tank includes two heat exchangers of different volumes. Heat exchanger of large volume is designed for water used for heating; heat exchanger of small volume is designed for water used for domestic purposes. Solar heat collector includes transparent panel; heat absorbing panel in the form of set of parallel metallic tubes for liquid heat transfer agent connected with lower surface of metallic radiant-energy absorbing sheet; heat insulation layer and supporting heat insulation panel. Parallel metallic tubes of heat absorbing panel are pressed-in to metallic radiant energy absorbing sheet, they are arranged along short sides of said sheet and mutually connected by means of tubes arranged along long sides of sheet. Supporting heat insulation panel, heat insulation layer, heat absorbing and transparent panels are fluid-tightly connected one to other for forming rigid structure construction, for example with use of bolts. On upper and lower surface of said construction along its perimeter metallic or polymeric shapes are mounted.

EFFECT: enhanced efficiency of using solar energy.
