In this paper, a procedure to model buildings and their thermal zones is studied. Since, ideally, the developed methodology should be applicable to different buildings, at different scales and in different locations, a feasibility study is necessary. The experiments used to test the flexibility of the model structure and the adaptability of the modeling procedure itself are presented. The obtained...
Thermostatic Radiator Valves (TRV) have proved their significant contribution in energy savings for several years. However, at low heat demands, an unstable oscillatory behavior is usually observed and well known for these devices. It happens due to the nonlinear dynamics of the radiator itself which results in a high gain and a large time constant for the radiator at low flows. If the TRV is tuned...
