ABSTRACT:
A heat storage apparatus and method including a heat storage medium encapsulated within a container and heat exchange apparatus for exchanging thermal energy with the heat storage medium. The heat storage medium may include a salt having a relatively high latent heat of reaction at a relatively low temperature range. The dehydration reaction of sodium sulfate decahydrate appears to the most promising reaction for this application. Other suitable salts and salt mixtures for other temperature ranges may also be used. The apparatus includes, where necessary, techniques for stirring the heat storage medium to inhibit stratification of the salt during cycles of dissolution and recrystallization or fusion.
