Solar energy subsystems employing isothermal heat sink materials
Abstract
Several encapsulation methods were studied: microencapsulation, encapsulation of powders and granules, and macroencapsulation. Microencapsulation of CaCl2:6H2O in polyester resin has been successful, and small wall, floor, and ceiling panels have been prepared and tested. Macroencapsulation in plastic film containers appears promising for hot air systems. Preliminary economic analysis studies of heating systems based on heat-of-fusion storage materials have shown several promising approaches.
