T-history 방법에 의한 잠열재의 열물성치 측정에 대한 실험적 연구

초록

The purpose of this paper is to propose the experimental method of thermal properties of Phase Change Materials (PCMs) by using T-history method. As far, in order to measure the heat of fusion and specific heat of PCMs, conventional thermal analysis methods such as DSC and DTA have been used. Becuase these methods test very small samples, thermal properties of samples are usually different from those of materials consisting of several components. For these reasons, T-history method, the simple measurement method of the heat of fusion and specific heat of PCMs (below 0 C)under the changing process by using T-history method. The results are compared to those of DSC method. The T-history method will be useful selection of the best PCM from lots of candidates and development of new PCMs
