SOLAR HEATING PANEL FOR BUILDINGS Russian patent published in 2002 - IPC

FIELD: solar-radiation construction engineering; construction of buildings heated by solarradiation energy. SUBSTANCE: wall panel for solar-radiation heating of building has face sheathing incorporating optical lenses, heat energy receiver made of heavy concrete with fine-grain filler and dispersed reinforcement arranged in a spaced relation to sheathing and used as heataccumulating and heat-transfer wall of building; heat-transfer members inserted on one end in seats provided in focal areas of lenses and on other end contacting solar-energy receiver through heat-retaining seats; and light-concrete heat- insulation layer with porous filler disposed above solar-radiation receiver so that it fills up clearance between receiver and face sheathing; this filler has taper air voids facing lenses at their long bases and heat-receiving seats, at shorter ones; heat-transfer members are made in the form of removable heat pipes unidirectionally conducting heat towards guide seats inclined to horizontal line; solar energy receiver has seats of heat-retaining material covered prior to installation of heat pipes into panel with lubricating layer; they are composed of seat proper and screw driven into it, screw head being a flush relative to inner surface of panel. During warm season heat pipes may be removed from panel either partially or completely. EFFECT: enhanced reliability of heat control due to provision for reversing direction of heat flow through tubes or removing the latter from panel. 1 dwg
