Thailand ventilation comfort chart
The paper presents a ventilation comfort chart that has been developed under Thailand climate and using Thai volunteers. 183 male
and 105 female college-age subjects were exposed to different thermal conditions in order to investigate the effect of air velocity on
thermal comfort in ventilated ‘‘non-conditioned’’ spaces. To this end, commercial electric fans were used to control the air velocity near
the subjects. The air velocity varied between 0.2 and 3 mrs. Room conditions varied between 268C and 368C D.B.T.. and 50–80%
relative humidity. Thermal sensation vote was recorded through a questionnaire. The Predicted Mean Vote was used to determine the
indoor neutral temperature. This developed chart could be used to design ventilation system for offices and classrooms. q2000 Elsevier
