Abstract
The invention relates to a solar accumulator, which is used to collect the sun rays to heat a heat conductive fluid medium contained within a piping system and an arrangement of plates--file bricks of high heat capacity. The heat produced is subsequently used to heat the air which is conveyed to the space to be heated. The air duct system employed making use of electrical relay controlled gates can alternatively be used for heating or air-conditioning/ventilating. Operation of the solar accumulator requires usage of an auxiliary or reserve energy source, e.g. electricity.
Claims2
A heating system comprising:
- glass panels defining a pyramidal solar radiation receiving chamber, means forming a bottom of said chamber having an air inlet aperture, a boiler defining pipe network containing a heat conductive fluid medium being located within said solar radiation receiving chamber, said pipe network extending upward to an overlying piping arrangement, said overlying piping arrangement being located within an arrangement of heat storing file bricks, defining a rectangular structure with an air outlet aperture, gaps being left for the passage of air within said arrangement of heat storing file bricks, said arrangement of heat storing file bricks being covered by metallic foil with an inward silver plated surface, a metallic housing about said metallic foil with insulating material in between said metallic foil and said metallic housing, a fan beneath said air inlet aperture to force air through said air inlet aperture into said radiation receiving chamber, duct means for the introduction of air or combustion gases into said radiation receiving chamber and for discharging air or combustion gases from said radiation receiving chamber, a first spring and relay controlled gate valve means in said duct means for controlling the suction of air from the surroundings in one position or from within a building in another position, a second spring and relay controlled gate valve means in said duct means when in one position is adapted to control the discharge of combustion gases from a chimney of an operating fireplace to the surroundings and in another position is adapted to control the supply of combustion gases from the chimney of an operating fireplace to said fan to heat said boiler and heat storing file bricks, a third spring and relay controlled gate valve means in one position allowing discharge of combustion gases after passing over said boiler and file bricks to the surroundings and in another position shutting an outlet to the surroundings to allow passage of heated air through said duct means to a space to be heated when a heating operation is required, a resistor adapted to be supplied with electric current situated above said air inlet aperture and below said boiler defining pipe network to alternatively or additionally warm the air circulating through said radiation receiving chamber and water circulating through said boiler defining pipe network, said boiler defining pipe network being connected to means for the introduction of cold water.
