The variable modes of operation in the model heater-fan-room system were studied experimentally and analyzed. The relative excess heat is proposed as a dimensionless parameter in the analysis and rationing of experimental data. The analysis of its evolution was carried out with an abrupt change in the performance of the air heater and at a fixed fan performance; with an abrupt change in the performance of the fan and a fixed performance of the air heater. The regularities and main qualitative types of evolution of relative excess heat in the elements of the model system were revealed.
