Originální abstrakt

The actual indoor temperature is represented by a complex interaction between losses and gains, which contribute through a large number of variables on the energy balance. These variables are continuously changing, because the temperature outdoors is changing with time, as well as the solar heat gains and the internal heat gains. In this work, a computer model has been designed by using TRNSYS software and MATLAB/SIMULINK software to simulate indoor temperature in summer. The building considered in this work is a lecture room at the Faculty of Mechanical Engineering at the Brno University of Technology. Where, the model of solar radiation incident on the external walls has been designed using TRNSYS software by exporting the real data taken from meteorological station in Brno (TUBO station) to the model, so that the intensity of solar radiation on each wall can be calculated and became usable in the SIMULINK model in order to calculate indoor temperature. To make sure of the validity of the results, they have been compared with those recorded by a monitoring system installed in the building. Results have shown a significant convergence between simulation and measurements.
