Evaluation of heat-pipe applications for passive solar systems. Final report, September 1977-June 1979
Heat pipes offer a significant dimension to a number of thermal control and design problems. Several unique characteristics of heat pipes make them ideally suited for applications involving passive solar heating systems. Among the more useful of these characteristics are: (1) long distance, isothermal heat transport,; (2) thermal diode behavior; and (3) passive operation. Several analytical models were formulated to predict the thermal performance of passive heating systems in a variety of climates. Systems that were simulated were of the Trombe mass wall type and included both conventional passive heating systems with movable insulation systems and heat pipe augmented mass walls. Parametric analyses of several design variables have shown areas of significant manufacturing cost savings with little sacrifice in thermal performance as measured in terms of solar fraction. An experimental model of a heat pipe augmented passive solar heating system was designed and fabricated. Experimental investigations were conducted to verify key design criteria in the development of the heat pipe concept. Several candidate heat pipe concepts are presented and discussed. Manufacturing considerations and analytical work are described as they relate to the final module configurations selection.
