The NASA-Langley building solar project and the supporting Lewis solar technology program

摘要: Abstract The National Aeronautics and Space Administration will use solar energy to heat cool a new office building that is now under construction at its Langley Research Center in Hampton, Virginia. Planned for completion December 1975, the 53,000 ft 2 , single story utilize 15,000 of various types collectors test bed provide nearly all heating demand over half air conditioning demand. This cooperative project involving joint participation between NASA's Lewis Cleveland, Ohio. Drawing on space-program-developed skills resources transfer, materials systems studies, NASA-Lewis technology support project. A program underway includes collector testing an indoor simulator facility outdoor facility, property measurements panel coatings, operation laboratory-scale model system facility. Based results obtained this program, select procure bed. selection be made late 1974 or early 1975. Early from tests indicate non-selective coatings behave more accord with predicted performance than do selective coatings. Initial experiments decay rate thermally stratified hot water storage tank have been run. Results suggest where high temperature required drive chiller, excess collected by should stored overnight form chilled rather water.
