Thermal Insulation and Control Performance of Phase Change Heat Storage Graphite Foam-Paraffin Composite
摘要
Abstract
Graphite foam-paraffin composite as a phase change material （PCM） was manufactured by melting and perfusing the paraffin into the porous graphite foams, which has high thermal conductivity under vacuum condition. Thermal properties of the composite material were tested by using hot disk and differential scanning calorimeter （DSC）. And the results show that paraffin can he uniformly absorbed into the pores network of graphite foams, and the composite exhibits much higher thermal conductivity than pure paraffin due to the heat transfer enhancement induced by graphite foams. Also, an experimental study was carried on the abilities of heat insulation and thermal control with the composite PCM which was applied as the building envelope. Comparing with the normal lightweight wall material, the composite material makes full use of the day and night temperature difference for the heat storage and release, thus represents better heat insulation effect from outdoor to inside. Meanwhile, it can evidently reduce the max temperature and temperature fluctuation in the room, hence greatly increases the indoor comfort level.关键词
