FIELD: solar technology.
SUBSTANCE: invention can be used to convert the radiated energy of the sun into thermal energy for the needs of air heating in domestic and industrial buildings. The solar boiler room contains glazing, a heat exchange element for heating air, openings for intake and supply of heated air. What is new is that the solar boiler house is designed to operate in two modes, providing recirculation and direct-flow flows of heated air. At the same time, the solar boiler house is made in the form of a separate room isolated from heat losses with glazing, located on the top floor of the building, in which heat exchange elements are installed, one of which is made in the form of a radiator wall (4), painted dark to absorb sunlight and then return in the form of thermal energy. The second one is made in the form of a radiator (5), inside which there is an air duct connected with intake, exhaust (7) and supply (6) air ducts, equipped with air valves (9), forming an air intake and distribution system to ensure operation in recirculation and direct-flow modes of air heating, moreover, the intake duct is installed with the possibility of taking in outside air and extracting the cooled air into the said room.
EFFECT: increased efficiency of the solar boiler.
