Description

Earlier studies (1,2,3) have shown that when man is exposed to a uniform moderate velocity (about 1m/s) over the entire body, he can be kept thermally comfortable by adjusting the ambient temperature. The magnitude of the adjustment can be determined from Fanger’s comfort equation (4,5) for any activity and clothing. Until now, however, only velocities from in front and from above have been examined. The purpose of the present study is to investigate whether man can be kept comfortable when he is exposed to a uniform velocity from other directions, and if so, whether the preferred ambient temperature at a given velocity depends on the direction of the air flow.

It is known that the turbulence intensity of an air flow can affect the convective heat transfer coefficient. It is conceivable, therefore, that it can also affect man’s sensation of comfort. A simple, introductory investigation of this phenomenon has been a secondary objective of the present study.
