STUDY OF THE THERMAL COMFORT IN A REPAIR WORKSHOP
Keywords:
PMV, PDD, CFD Simulation, HVAC, Thermal ComfortAbstract
Car mechanics are exposed to high-temperature discomfort in a repair workshop during their daily work. This work studies thermal comfort in auto workshops by determining the PMV (Predicted Mean Vote) and PDD (Predicted Percentage dissatisfied Index) according to the actual standards. The first part of this work presents the current stage of the method for determining thermal comfort by applying a computational fluid dynamics method. The second part of this paper presents the modelling of the internal volume of the repair workshop and the existing work components. In the third part of the paper, the boundary conditions for thermal comfort are created for two cases: in the first case, the heating radiators are opened, and the cooling system works in the heating regime, and in the second case, the heating radiators are closed, and the ventilation system works in the cooling regime. In the final part of the work, the results and conclusions of this study are presented.
