Finned Tube Solid Heat Storages

摘要

In the report, two heat storage constructions are considered. The first is a heat storage that is insulated from the surroundings. The other is a floor heat storage that gives heat from the surface to the room. A solid material is used as the heat storage medium, and a fluid is used as the heat carrier. The heat exchange between the heat storage medium and the heat carrier fluid is enhanced by using plate fins on the heat carrier tubes. The heat conductivity of the heat storage medium is usually low, and the fins may have a great effect on the rate of the heat transfer. The finned tube solids heat storage suits well for high temperature applications, in which usually expensive pressurized vessels are used as heat storages.
