Numerical Study on the Effects of Air Conditioning in Office of Personal Partitions
Abstract
Numerical simulation using computational fluid dynamics (CFD) was performed to calculate the predictedmean vote (PMV) based on velocity and temperature profiles of air in a partitioned office building. Theoffice building (W:14.65 m, D:7.57 m, and H:2.63 m) was divided by partitions of 1.5 m height and sharedby 7 office workers. Each person uses a personal computer and printer on a desk. One stand-type airconditioner was installed in the corner of the room and operated at the variable flow rate of 35 ㎥/min. Inthe case study, we assumed that the initial temperature of the room was 303 K and it was cooled down byoperating air-conditioner. The outside temperature was fixed at 303 K and the heat flux through the windowswas included in the calculation. Heat sources of personal computers, human bodies, fluorescent lamps, andrefrigerator were considered. The temperature and PMV values were also calculated to asses the thermalcomfort of each person by operating time of air conditioner. It was found that the thermal comfort could beimproved by changing the angle of diffuser grill of air conditioner.
