Abstract
Disclosed is a method for enhancing thermal energy storage performance of industrial grade hydrated salts based on phase change, comprising: heating an aqueous system of industrial grade hydrated salts containing 105-130 percent (%) by mass of m0 industrial grade hydrated salt to m0, taking a sample for differential scanning calorimeter testing and recording its melting enthalpy as ΔH1; melting and adding water into, or melting and evaporating the residual aqueous system of industrial grade hydrated salts or the residual industrial grade hydrated salts system with a mass of m1 to increase or decrease the mass by 0.4-0.8% m0 until a melting enthalpy ΔHn of a sample that taken from the residual aqueous system of industrial grade hydrated salts with a mass of mn satisfies ΔH2< . . . <ΔHn>ΔHn+1.
