Overall thermal comfort

Nowadays many people spend most of their time indoors, so the quality of indoor air has significantly impacted human health and comfort. The purpose of the present work was to determine the thermal comfort and suitable air intake rate for Thai people in air-conditioned buildings. A field study was conducted in three types of building from six provinces of Thailand; 698 occupants responded to the questionnaire while simultaneous indoor air quality measurements were taken.

Thermal sensation, acceptability and comfort are the important responses while evaluating the qualityof thermal environment. Experimental investigations into the relationships between these responseswere performed separately under uniform and non-uniform conditions that produced by local cooling.Thirty male Chinese subjects in college age participated the experiment and reported their local thermalsensation of each body part, overall thermal sensation, acceptability and comfort. Under uniformconditions, overall thermal sensation, acceptability and comfort are correlated closely.
