Air infiltration through revolving doors may have significant impact on the heating load of commercial and institutional spaces, and may create discomfort to people. This paper modifies a 40-year old model by Schutrum et al. (1961), composed of two components:
(1) estimation of air exchange between one segment of the revolving door and the indoor/outdoor,
(2) estimation of net air infiltration rate.
Discusses two main methods of fan-assisted air supply to a room - mixing ventilation and displacement ventilation. Gives a detailed account of the effects which furniture and the opening of doors have on a room and discussses factors such as vertical temperature variations, air velocity at floor level. Illustrates these effects in diagram form. Notes difficulty in translating older comfort criteria for use in displacement ventilation.
