Solar subsystems and components were identified and conceptual structure was developed for architectural solar energy heating and cooling systems. Recent literature related to solar energy systems was reviewed and analyzed. Solar heating and cooling system, subsystem, and component data were compared for agreement and completeness. Significant aspects of the analysis were the greatest consensus of systems, on-the-shelf availability, and cost-effectiveness of the solar systems. Six subsystems common to all solar systems were identified: collector, storage, distribution, transport, auxiliary, and control subsystems. Three components were found that could be common to all the solar heating and cooling systems--preheat domestic hot water, heat exchanger, and heat pump. Conceptual structures were developed for active and passive air and liquid solar heating and cooling systems. Hybrid solar systems, solar retrofit, and solar domestic hot-water systems were also studied. (The study is recommended as the basis for solar curriculum development.) (YLB)
