摘要
Energy storage of phase change materials used in the building envelopes such as the wall or the floor is more and more valuable. Polyalcohols solid–solid phase change materials have become important because of its advantages. In this paper, the phase change temperatures and phase change heats of monobasic, binary and triatomic systems consisting of neopentylglycol, pentaerythritol and trihytdroxy methyl-aminomethane with different component were studied experimentally by differential scaning calorimeter (DSC). Feasibility of materials used in the building envelope was analyzed. The research is to find suitable polyalcohols mixtures with different composition used in the building envelope. Results can provide the basis for the application of solid–solid phase change materials in the building fields.
