The Solar Energy Applications Laboratory of Colorado State University has completed the design, construction, and installation of a complete set of evacuated tubular collectors on a test bed behind Solar House I. The collectors, the Corning evacuated tube collector (December 16, 1976 to December 31, 1977) and the Philips evacuated tube collector (January 16, 1978 to January 31, 1979) are being used sequentially to operate the heating and cooling system of Solar House I. Data are being collected over an entire heating and cooling season and analyses are being performed on these data to provide an evaluation of the two new collectors and comparison with the present conventional collector as part of a residential heating and cooling system that is otherwise identical in every way. This project is significant for several reasons. First, the two high performance collectors operate in conjunction with an advanced ARKLA lithium bromide water chiller. This cooling unit is designed specifically for operation with solar energy systems. For comparative purposes the advanced ARKLA unit will be available for use with the existing conventional flat-plate collector. In addition, comparisons of operating data are being made with Solar Houses II and III, adjacent to Solar House I. Solar Houses II and III have the same thermal load characteristics as Solar House I, but have different solar heating and cooling systems. House II has an air heating collector and pebble-bed storage. House III has an evacuated tube solar collector, and is also coupled with an advanced absorption water chiller unit. The comparative analysis under the same load conditions, provides an exceptional opportunity in evaluating the relative merits of the new collector systems.
