| Abstract: | The comparative performance of Solar House II collectors (air heater) and Solar House I collectors (liquid heater) is presented. In the 1976 comparison year, there is no conclusive evidence that either system provides a greater fraction of the seasonal load. Both systems were designed to provide approximately 75 percent of the annual space and water heating load, and the design targets are reasonably achieved. In February, 1976, the air system provided 65 percent of the total requirement while the liquid system provided 76 percent. In March, based on a few days of data, the performance was substantially the same. In April the air system provided a greater fraction of solar heat to the total need, but the use of the heat was different, more being used for domestic water heating in Solar House I than in Solar House II. The data for 1977 have not yet been fully analyzed for both solar houses and therefore, a complete comparison cannot be made. At this stage in the evaluations, it can be stated that either system can be designed to achieve the target fraction of the total annual heat requirements. (WHK) |
