Apparatus for storing heat

摘要

A heat exchanger for cooling is immersed in a vessel for storing heat filled with a heat-storing material of latent heat type. The heat exchanger for cooling is positioned at an upper level in the vessel when a heat-storing material having a higher specific gravity in a crystal state than in a liquid state, such as calcium chloride hexahydrate, is used, whereas at a lower level in the vessel when a heat-storing material having a lower specific gravity in a cystal state than in a liquid state such as water, is used. Crystals of a heat-storing material formed and deposited on the outer periphery of the heat exchanger for cooling when the apparatus for storing heat is in operation are accumulated in the vessel for storing heat as blocks.
