Solar energy subsystems employing isothermal heat storage materials, phase 1
Abstract
The literature was searched for phase-change solar heat storage candidate materials melting in the range 10 to 90 C. About 200 salts, organic compounds, and eutectic substances were selected initially. These are tabulated in this report. Through the use of DTA and freezing curve data, this group was reduced to approximately 50 candidates, about 20 of which exhibit little or no supercooling. The latter are prime candidates for encapsulation studies. Heat of fusion measurements have been made on most of these 20 materials. Thermal cycling studies have begun, and other tests are under way.
