摘要：The research subject of the current work is ventilation and cooling simulations of the laboratory in summer conditions using CFD software. The simulations were made in ANSYS Fluent 14.0. For the validation of the simulation results a series of the measurements were made using computer regulation technique and SIEMENS software. According to the result,conclusions were made about the necessity of the ventilation and cooling simulations and their effect on the thermal comfort of the humans in the closed areas. In the simulation were taken into account not only the primary thermal gains – sun,air temperature but also the secondary thermal gains from the computers,monitors and humans.
