An effective method to reduce energy consumption for heating a building is by incorporating shape–stabilized phase change material (SSPCM) in building floors. In this study, a new type of SSPCM with increased thermal conductivity is formulated through a self–established experimental device. A model to analyze the thermal performance of the SSPCM floor is developed. The model is used to analyze the thermal performance of the SSPCM floor with two heating positions, one at the bottom and the other in the middle of the SSPCM. Results show that when the heating position is in the middle of the SSPCM, the melting speed is faster and the melting degree of SSPCM is larger than when it is at the bottom.

Change Material

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 floor based upon shape-stabilized PCM is put forward which can adsorb 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 is developed. By using the model, the influence of various factors (thickness of PCM layer, melting temperature, heat of fusion, thermal conductivity of PCM etc.) on the thermal performance is analyzed. The model is verified with the experimental results. The model and the analysis are helpful for the application of shape-stabilized PCM based floor in solar energy buildings.

The addition of phase change material (PCM) to a transparent polyester panel is used to create an energy absorbing building material that can be used for daylighting. One of the key development needs of this energy efficient material is the identification of the thermal properties. Without a clear understanding of the thermal properties and thermal performance with embedded solid and liquid PCM, design optimization is not possible. This experiment analyzes the thermal conductivity of various mixtures of thermoplastic polyester and PCMs. It was determined that the addition of PCM slightly increases the thermal conductivity of panels when the PCM is solid. Once the PCM has melted, the panel conductivity is lowered.
