Case Study of the Brownell Low Energy Requirement House (Thermal Storage Analysis).

摘要

An analysis is made of the thermal storage performance of an innovative residence built in the Adirondacks area of New York State by Adirondack Alternate Energy. A detailed case study report of this residence will be issued shortly by Brookhaven National Laboratory. Effective integral thermal storage provided by the exposed interior building structure,serves to keep interior temperature swings within acceptable limits. Additional remote thermal storage,is provided in the form of a large sand bed,with air ducts located below the basement floor slab. The building was instrumented and tested by BNL staff during January,February,and March of 1978,with technical assistance provided by the builder's staff. The thermal storage effects of the remote sand bed and the building materials available for thermal storage within the structure are quantified. The thermal storage performance of the exposed building materials was found to be quite effective. The existing sand bed,however,has a diurnal storage utilization factor of only 8%. Two hypothetical designs are shown which improve the storage bed utilization to 38% for a sand bed with an enhanced duct system and 61% for a ducted concrete slab. Other comparisons of these storage beds are also made,including a comparison with a rock bed storage system. (ERA citation 04:043270)
