碩士 === 國立臺灣大學 === 土木工程學研究所 === 101 === In this study, a single phase change material and the ternary phase change material are used. Encapsulating by the coarse method, and then conbine with the concrete wall. The hot box test is carried out to explore the thermal behavior of the wall containing the phase change material. The effect to the indoor temperature of the phase change materials'' position in the internal wall is discussed, and effect of the total value of the latent heat of phase change materials for thermal behavior as well. The finite element software ABAQUS is used to simulate the behavior of the wallboard in the experimental situation, and compared with the experimental results. Results of the wallboard containing phase change materials and the wallboard without phase change materials are compared, both experiment and simulation show that the former peak temperature of the high temperature is lower than the latter and the low temperature is higher and there is the effect of the delay time. the experiment and simulation results show that the phase change materials which are installed close to the test side is ideal. The panel with the higher total latent heat will reduce the peak of high temperature by the experimental results.Besides, the thermal behavior effects of panel containingsthe copper tube is discussed, it can be seen that wallboard containing copper can cause high peak temperatures rise and the delay time becomes shorter.
