Simulation and experimental evaluation of thermo-active textiles for energy efficient space heating and cooling

在第一个资助期间（2014年5月至2016年4月），用适当的现成方法生产了几种具有热活性的纺织品原型。接下来，对原型进行了力学和热性能分析。纺织品的加热和冷却性能数据是在可重复的条件下在专为此类测试而设计的测试室中进行的实验得出的。此外，还对原型的热行为进行了全面的数值研究。首先，对实验进行了对比模拟。其次，将结果转化为实际房间的应用。实验结果与数值结果吻合良好，表明热活性纺织品在空间加热和冷却方面具有很大的潜力。在实验和模拟的基础上，原型的开发正在进行中。它将被转移到两个演示器中，这两个演示器涉及到能够加热和冷却气候室的纺织技术。热敏纺织品将配备传感器，以改善控制操作。演示器的功能将通过气候室的实验和虚拟气候室的模拟来验证。此外，在前人数值计算的基础上，对热活性纺织品的实际应用进行了全面的模拟。

During the first funding period (05/2014-04/2016) several textile prototypes with thermo-active abilities were produced with appropriate readymade methods. Following, the prototypes were analyzed for their mechanical and thermal properties. Heating and cooling performance data of the textiles have been derived from experiments carried out under reproducible conditions in a test chamber designed for these kind of testing.Additionally, comprehensive numerical studies of the thermal behavior of the prototypes were performed. First, comparative simulations of the experiments were done. Secondly, the results were transferred to applications in real rooms. The available data show a very good match between experimental and numerical results as well as a great potential of thermo-active textiles for space heating and cooling.The development of prototypes is going on, based on both, experiments and simulations. It will be transferred into two demonstrators which are in dimensions and concerning textile technology able to heat and cool a climate chamber. Thermo-active textiles will be equipped with sensors to improve control operations. The functionality of the demonstrators will be validated by experiments in the climate chamber and by simulations in the virtual climate chamber.Furthermore, based on previous numerical calculations comprehensive simulations are planned regarding thermo-active textiles in real applications.
