In order to analyze the effects of various temperature modifiers on the phase change temperatures and the latent heat values of the phase change of CaCl2·6H2O-SrCl2·6H2O composite phase change materials,CaCl2·6H2O-SrCl2·6H2O was used as the phase change substrate,and urea,ammonium chloride,ethylene glycol,glycerol,propanetriol,sodium chloride,and potassium chloride were employed as the phase change temperature regulators.The experimental results indicated that ethylene glycol and propanetriol could significantly regulate the phase change temperature of the composite phase change materials,with less subcooling and relatively higher latent heat values,followed by urea and ammonium chloride,while sodium chloride and potassium chloride had poor temperature adjustment,increasing the degree of subcooling of the composite phase change materials and negatively affecting the heat storage capacity of the composite phase change materials.
