Abstract
At a time when energy saving is critical, one of the ways to reduce unnecessary energy losses is to provide a feeling of thermal comfort for people staying in closed utility rooms. It is important to properly determine and maintain indoor conditions to achieve the desired effect of the operation of ventilation, air conditioning or heating. In this type of issues, the numerical fluid mechanics comes to the aid. The paper presents the results of modelling of heat transfer process in the utility rooms and prediction of the thermal comfort by means of CFD code. Calculations were made for the auditorium in which measurements of inside air parameters were previously performed. Calculations were made for two turbulence models k-e Standard, k-e RNG. The differences between numerical and experimental values vary between 5 to 40 % depending on the locations of the measurement points.
