The IBM-Carlsbad Solar Energy System is located in a single family residence at Carlsbad Caverns National Park, New Mexico. This hot air solar heating and hot water system consists of 408 square feet of SEPCO, flat plate air collectors, a rock storage bin containing 12 tons of 3/4'' to 2 1/2'' diameter rocks, an energy transport system, air-to-water heat exchanger, controls and a hot water preheat tank which supplies preheated water to a 52 gallon electric hot water tank. An oil hot-air furnace supplies necessary energy when solar energy is insufficient to supply the space heating load. The system has five different modes of operation and became operational in March, 1978. The following topics are discussed: system description, performance assessment, operating energy, energy savings, maintenance, summary and conclusions.
