Title: Design and construction of a residential solar heating and cooling system. Semi-annual progress report for January 1, 1974--July 31, 1974
Abstract: The first integrated system providing heating and cooling to a building by use of solar energy has been designed and installed in a residential-type building at Colorado State Univerdity.Solar heated liquid supplies heat to air circulating in the building and to a lithium bromide absorption air conditioner.Service hot water is also provided.Approximately two-thirds of the heating and cooling loads are expected to be met by solar energy, the balance by natural gas.The report contains details of design and principles of operation.A breakdown of actual costs of the equipment and its installation is also provided.iii Statement of ObjectivesThis project is a nominal two-year effort to design, construct, test, and evaluate an experimental system for utilizing solar energy to drive heating, cooling, and.hot water subsystems, supplemented as necessary with auxiliary (oil or gas) fuel.The program is designed to provide the following information:, a.design data for integrated systems and the various subsystems, b.system performance for heating, cooling, and water heating, c. operating economics, d. verifi cation of the Uni versi ty of Wisconsin model, e. design and operation of automatic controls, f. correlation of standard Weather Bureau data with on-sitel insolation data, and g. system reliability evaluation.
