Description
Thermal comfort within a Field Environmental Chamber (FEC) office mockup was numerically simulated throughout the present paper. The goal of this research was to determine the best scenario to provide conditioned supply of air and distribute it inside an office room by using Mixing Ventilation (MV) and Personalized Ventilation (PV) systems to create the best status of thermal comfort for a sitting occupant who is typing in front of a computer screen. Computational Fluid Dynamics (CFD) method was used and specifically ANSYS FLUENT 14.0 commercial package software to compare the thermal comfort conditions for the occupant with different strategies of air distribution with various flow rates either being used solely or concurrently. Thermal comfort mathematical indices like the Predicted Mean Vote (PMV) and the Predicted Percentage of Dissatisfied (PPD) were implemented in the software and their contours were shown to define the thermal comfort status more precisely. It was concluded that using PV systems to maintain thermal comfort conditions for a working office occupant can be very effective and an attractive solution for designers to consider in situations similar to the study.
