Abstract

A passive solar system for temperature control of the air inside homes and other buildings, comprising a pool of water to receive, store and dispense energy from direct sunlight passing through a glass wall, to strike the surface of the water in the pool. The pool has open connecting passage under its bottom and vertically along one of its sides, to form a convective conduit in which cold air is heated by the stored heat of the pool. Adjustable passages are placed through interior walls for convective flow of the pool-heated air into all desired parts of the building. The glass wall is advantageously placed for maximum incidence of heating sunlight upon the pool in winter, and maximum shading of the pool in the summer. A retractable eave may be provided to enhance these effects. During summer days, the pool serves as a heat sink, cooling the interior air. During summer nights, cooler outside air is admitted to the building to displace the warm air through ceiling and attic vents, cooling the building air, as well as the pool for the next day's use.
