EFFECTS OF LOCAL NON-ISOTHERMAL AIRFLOW DURING NATURAL VENTILATION ON INDOOR COMFORTABLE TEMPERATURE: Subject experiment at room temperature 22℃ and 29

In this study, we aimed to clarify the effect on comfortable room temperature when various local low-temperature airflows occur during natural ventilation, and calculated PMV-teq from the body equivalent temperature of the thermal manikin experiment. Comparisons were made with the thermal sensation results of subject experiments under these conditions. As a result of the subject experiment, under the 29℃ condition, the PMV-teq and the average thermal sensation value were close to each other. However, under conditions of 22℃, the subjects felt colder than expected based on PMV-teq, and it seemed necessary to consider local discomfort as well.
