Isothermal solar heat storage materials
Abstract
A group of over 200 potential phase change heat storage materials, melting from 10-90C was identified. Laboratory tests narrowed these to materials recommended for hot faucet water, hydronic heating, forced air heating, heat pump application, radiant wall panels, and stored cold systems. Several encapsulation methods were studied: micro-encapsulation, encapsulation of powders and granules, and macro-encapsulation. Micro-encapsulation of CaCl2.6H2O in polyester resin has been successful, and development of wall, floor, and ceiling panels is under way. Macro-encapsulation in plastic film containers appears promising for hot air systems.
