The purpose of this study was to clarify the effects of localized cool airflow on thermal comfort in muggy condition. The experiment was conducted in summer. The subjects (6 young females & males) were exposed to the following conditions: combinations of air temperatures (Ta = 30oC, 33oC), discharge temperature (Tdc = 15oC, 20oC) and relative humidity (RH = 50%, 80%) The following results were obtained: For the whole parts of the body thermal sensation were voted [-1: slightly cool]~[+1: slightly warm]. The skin temperature of the head in contact with the airflow was affected by the low discharge temperature (15oC). The skin temperature mentioned was from 31.5oC to 33.3oC. The mean skin temperature ranged from 33.8oC to 34.5oC. We prove that localized airflow could relieve muggy conditions even to 35oC of mean skin temperature. |
