<p>METHOD AND SYSTEM FOR THE COMPACT STORAGE OF HEAT AND COOLNESS BY PHASE CHANGE MATERIALS While many materials and additives which will melt and freeze at various temperature levels for storing and releasing large amount of heat thereby per unit volume have been disclosed, the packaging of these materials with suitable non-corrodible long-lasting heat exchange structures has been cumbersome and expensive The present invention provides an inexpensive, high performance, non-corrodible thermal storage method and system adaptable to materials over a wide range of temperatures, including a heat exchanger which provides uniform phase change throughout the volume of the entire storage mass. Problems of thermal expansion, stratification and subcooling are eliminated. Thermal storage methods and systems embodying the present system may advantageously be used for off-peak storage of electric refrigeration, cooling and heating as well as solar heating and other applications.</p> |
