| Research Abstract |
The cooling effects by natural wind fluctuation and sweat evaporation are very important for evaluating the thermal comfort condition in cross-ventilated environment. It was found that the frequency of sweating rate had a high correlation with the frequency of sinusoid wave flow and the evaporation heat loss through sweating was promoted in longer frequency of wind velocity than in higher frequency. Through field measurement of naturally ventilated building, it was found that the 60% of office workers in the investigated room could not feel the movement of air in intermediate season because the naturally ventilated vents were located under the windows. A COMIS-LDSM model with a combination of TRNSYS thermal multizone building model was proposed. Furthermore the Predicted Mean Vote was incorporated into the TRNSYS network model and currently the verification of the network model is being undertaken.
