太阳池水合盐相变贮热的探讨

太阳池水合盐相变贮热能形成梯度层，既显热贮热又相变贮热，具有跨季大容量单一体系热贮存的特点，全年热循环仅３－５次。可以采用溶解盐粒子等办法使相变材料贮热能力再生，讨论了几种水合盐的相律和溶解度，为选择适用于太阳池的相变材料提供参考。

SEEK FOR HYDRATE-SALTS OF THE THERMAL STORAGE IN SOLAR POND

In this paper, the possibility of using hydrate-salts in solar pond as phasechange heat storage material is discussed, due to its formation of gradient layer for both sensible and latent heat storage for seasonal heat storage with only 3-5 cycles year round. The solution salt particles could be used for the regeneration of heat storage capability of that phase-change materials.
