A novel form-stable phase change material (FSPCM) was prepared, which comprises micro-encapsulated paraffin (MEP) as the latent heat storage medium and high density polyethylene/wood flour composite as the matrix. It has the following merits: proper phase transition temperature, large apparent specific heat in phase change temperature region, suitable thermal conductivity, good shape retention and dimensional stability. Therefore, it is suitable for the applications in energy efficient buildings without encapsulation. Simulation studies were performed to investigate the temperature-regulating and cost-reduction effects of the FSPCM as the thermal storage layer (TSL) material of an electric floor heating system (EFHS). The results show that it is promising to use the FSPCM plate as the TSL to achieve better temperature-regulating and cost-reduction effects, and the application effects depend on the heating mode of the EFHS and the thickness of FSPCM plates. The cost-benefit analysis indicates also that the prepared FSPCM has the potential to serve as the TSL in an electric floor heating system. 相似文献

Shape-stabilized phase change material (PCM) is a kind of novel PCM. It has the following salient features: large apparent specific heat for phase change temperature region, suitable thermal conductivity, no container. In the present paper, a kind of shape-stabilized PCM floor is put forward which can absorb the solar radiation energy in the daytime and release the heat at night in winter. Therefore, in winter the indoor climate can be improved and the energy consumption for space heating may be greatly reduced. A model of analyzing the thermal performance of this shape-stabilized PCM floor is developed. By using the modeling, the influence of various factors (thickness of PCM layer, melting temperature, heat of fusion, thermal conductivity of PCM, etc.) on the room thermal performance was analyzed. The model was verified by the experimental results. The model and the analysis are helpful for the application of shape-stabilized PCM floor in solar buildings. 相似文献
