Thermal energy storage material

Abstract

Abstract PURPOSE:To provide the titled material composed of CaCl2.6H2O containing anhydrous bromide, anhydrous nitrate and hydrated chloride, etc., and suitable for the heating of an agricultural vinyl house with solar energy. CONSTITUTION:The objective thermal energy storage material is composed of CaCl2.6H2O containing (A) an anhydrous bromide (e.g. NH4Br, KBR, etc.), (B) an anhydrous nitrate (e.g. NH4NO3, KNO3, etc.) and (C) one or more hydrate of chlorides, bromides and nitrates [e.g. MgCl2.6H2O, CaBr2.6H2), MgBr2. 6H2O, Ca(NO3)2.4H20, Mg(NO3)2.6H2O, etc.]. EFFECT:Free from the formation of non-uniform composition and the tendency of supercooling. Excellent solidification characteristics and phase-transition stability.
