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.
