Slope Effect of Phase Change Materials in Phase Change Roof

Abstract:

Under summer climatic features of Daqing area in China, numerical simulation on the unsteady heat transfer characteristic of phase change roof was investigated, considering direct influence of solar radiation. The main influencing factor of roof slope in the phase change roof was analyzed in this paper. The results show that, increasing the roof slope is beneficial to promote the effect of heat-insulating and temperature-reducing of phase change roof, whereas the extent of the ascension is weak. Different slopes in roof structure have basically no influence on the delay effect.
