Condensation of Humid Air Predicted by Numerical Model and Compared With Experiment

The quality of environment, not only outside but also inside buildings, is at the forefront of interest of experts as it greatly affects the efficiency of work processes and the perceived well-being. One of the most important factors for perceived comfort is the amount of moisture contained in room and circulation associated with it. This paper summarizes results and methods used to determine and validate amount of condensate created from humid air in floor heat exchanger. Paper contains theoretical and practical knowledge connected with perception of environment quality, determination of humid air state variables, design elements of heat exchangers and also summary of published scientific articles on humid air condensation under normal atmospheric. Main vision is to create one virtual model with corresponding settings and boundary conditions which will precisely calculate amount of condensate from flow created under defined conditions. For validation purposes experiment was designed, created and run. Results of both methods are presented, compared and discussed with respect to their range of use for practical purposes.
