摘要：

The occupants' thermal comfort in an office building served by an under-floor air distribution (UFAD) system has been assessed using a number of different methods: field survey, physical and subjective measurements, and computational fluid dynamics (CFD) analysis. Results show that for rooms conditioned by UFAD systems, the Predicted Mean Vote (PMV) index was misleading, whereas the Air Distribution Performance Index (ADPI) was more indicative of the relative level of occupants' thermal comfort in the room. The CFD model search for the best operating conditions that maximize the occupant's thermal comfort resulted in a 90% improvement in the ADPI compared to the existing conditions. This was accomplished by setting the supply air temperature to 21 degrees C and inlet velocity to 1 m/s. (C) 2014 Elsevier Ltd. All rights reserved.
