Document Type and Number:
Japanese Patent JP2502411
Kind Code:
B2
Abstract:
PURPOSE:To automatically control a concentration of inhibitor to prevent corrosion of a metal material for a heat accumulator using heat storage medium containing high temperature dense aqueous halogenide solution as a main content. CONSTITUTION:In a sealed circulation type heat accumulator using heat storage medium, an inhibitor supply unit 9 is provided partly in a circulation system of a heat storage medium tank 3 and a heat exchanger 7. The inhibitor in the medium is consumed as an operating time is elapsed, and the inhibitor is always continuously supplied by using the fact that solubility of the inhibitor to the medium is increased in amount corresponding to the consumed amount. An electric heating tube 14 is provided in the unit 9, and the unit is controlled to a low temperature side temperature of the operating temperature of the accumulator.
