In this paper, using a dynamic RC model for heat transfer in a room on the ground floor,
the three-time constants of heat transfer that corresponds to the different parts of a
weekend cottage on Kopaonik were determined. The model considered the heat
accumulation and losses through the facade wall, floor and interior part of the room. The
time constant of the wall is the characteristic time for establishing a stationary state of the
temperature inside the wall during rapid changes in the external air temperature and it
represents a measure of the thermal inertia of the wall. The model was validated by
experimental measurements of air temperatures and wall surface temperatures.
Measurements were carried out in situ continuously for 21 hours in real conditions in the
winter period. Air temperature measurements were made with standalone data loggers.
The paper presents the results of the measurements, the parameters and the electrical
diagram of the RC model and the ...results comparing the measured temperatures with the
same temperatures obtained by this model. Satisfactory agreements were obtained.
