Development and Evaluation of Thermic Diode Solar Panels for Building Heating and Cooling. Final Report:November 1, 1975--October 31, 1977.

摘要

This report covers research completed between November 1975through October 1977regarding various aspects of the thermic diode solar panel. Three specific aspects of the research are:market analysis,cost--volume study,and heat transfer analysis. The thermic diode solar panel is a passive solar energy system for space heating or domestic hot water heating. The thermic panel is also modular,has no moving parts,and is easily installed. Each panel contains all the necessary ingredients of a complete solar energy system:collectors,controls,storage,heat exchangers and ducting. In the market analysis,questionnaires were returned from about 80building contractors throughout the country. Six barriers were identified which must be met for a solar heating system to be accepted by the marketplace (in order of importance):initial investment cost,operating cost,warranty period,number of successful installations,expected life,and payback period. The cost--volume study found the manufacturing costs of the panel at various production volumes. At the highest rate, 10,000units/year,the factory price as delivered to the stie was about $6.00/ft exp 2 . Heat transfer analyses,verified by experimental data taken on a scale model panel,showed how stratification of water in the panel's storage tank alters the flow rate. (ERA citation 04:044626)
