The quantity{amount} of heat acting in a premise{room}, in many respects depends on orientation of a stained-glass window, its{his} sizes, a kind остекления and shading devices.
Thermal action of a wall-stained-glass window to adjust{regulate} difficultly. Sharp temperature drops in premises{rooms} behind a stained-glass window, connected with changes of external temperature within day, negatively affect a condition of the person. Dependence on weather and time of day, unreliability of night heating, low heat-sink ability and general efficiency do{make} walls-stained-glass windows, despite of simplicity of the device and rather small cost, ограниченно suitable for application. Their use in areas with a lot{plenty} of sunny days and rather warm nights is the most expedient.
2. " Greenhouses ", as well as walls-stained-glass windows, are the elementary type of passive system solar энергосбережения. In system "greenhouse" for heating premises{rooms} warm air, нагретый as a result of influence of solar beams which get through the glazed walls and coverings of the special auxiliary glazed premises{rooms} - greenhouses is used. As well as in system "wall-stained-glass window", in system "greenhouse" for heating air the hotbed effect serves. Difference consists that the sun heats up not premises{rooms}, and a greenhouse from which air due to конвекции through special apertures in a wall dividing{sharing} a greenhouse, and premises{rooms} a subject heating flows in the last and warms them. Additional quantity{amount} of heat of a premise{room} receive due to heat accumulated by a wall, separating them from a greenhouse. Important, what is it warmly the premise{room} receives not during a direct solar irradiation of a greenhouse, and a little bit later, that allows to prolong effect of action системотопления, to soften temperature differences. Except for effect of heating, the greenhouse provides protection of a heated premise{room} from теплопотерь, covering an external wall from direct contact to external space (fig. 5, 5).
Economic benefit of system "greenhouse", in view of various forms of maintenance of a premise{room} heat, above, than at a wall-stained-glass window.
3. " With т е н and the Blood clot ", offered by the professor the Blood clot, director of the National center of scientific researches in Одейо (France), uses, as well as first two systems, a hotbed effect arising at heating by solar beams of a massive external wall at home. A wall зачернена on all area остекления. Glass is located on distance of 15...20 sm from a wall. Air which is being space, formed by a wall and glass, gets warm beams of the sun, rises upwards and through the apertures done in a wall, gets in an adjoining premise{room} and warms it{him}. Cooled down in air falls downwards and through apertures in the bottom part of a wall comes back in an interval between a wall and glass and, again heating up, rises upwards and gets in a warmed premise{room}. Such circulation нагретого and the cooled air, providing heating of a premise{room}, occurs{happens} in the afternoon. At night heating is reached{achieved} by heat radiated massive, теплоемкой by a wall - the accumulator of heat. Practically the wall serves as the receiver of a solar energy, its{her} accumulator and the device of heating (fig. 5,6).
