This work is primarily concerned with the analytical design of wind space and water heating systems for residences. A development of a digital computer based methodology to calculate system performance and costs is presented. In addition to wind powered systems, solar, and combined wind and solar systems are considered in detail. The analysis i s based on two separate computer programs: An energy program that determines system performance as a function of subcomponent parameters and auxiliary energy requirements, and an economics program that calculates present and future (mass produced) costs of the wind and/or solar components and system. Complete details of all parts of the model, which is intended to be a general design tool for such systems, are presented.
The results include a detailed series of runs based on hourly weather and solar data for a "typical" New England site, using an "Average" and "Mociel" (well insulated) residence model. Also, additional runs are presented for other sites and residences. The performance and economic results show that wind and/or solar systems are presently competitive with electric based heating systems. It is also shown that in the future such systems will be competitive with oil or natural gas heating systems.
