The development of efficient heating and cooling systems has been a major research focus in recent years. In particular, surface tempering systems are often the subject of these investigations, partly because view in heating mode they are very advantageous from an exergetic point of and additionally they produce comparable or higher thermal comfort than convection heating systems at lower room air temperatures, which means that they can result in lower energy consumption in the building.

Two research approaches are being pursued in this research project. On the one hand, a fundamental investigation of the influence of wall tempering systems will be carried out in the course of comfort studies within different comfort models. On the other hand, comparative comfort studies of surface tempering systems will be carried out, in which both the subjective perception of test persons will be noted and objective measurements will be made with the help of a thermal manikin in the two-zone climate chamber of the TUK.

Aims of the project are, among others, the acquisition of comprehensive knowledge of the most important influencing parameters of thermal comfort in wall tempering systems as well as the quantification of the size of possible energy savings due to increased comfort at lower room air temperatures.
