Large capacity heat storage device - has filled hollow elastic balls for infill in side insulating container

摘要

A heat storage system of large heat storage capacity is constructed in such a way that a highly cumulative storage container (11) is fitted out with a feed or pipeline system (14) through which a heat transfer medium may be transported or pumped. A filling composed of a very large number of hollow resilient balls is provided within the cumulative storage container. The balls (13) are filled with a phase change material (22, 32) and also with a heat storage fluid.
