This paper reports observations by the authors made in the course of performing field surveys and detailed analyses of approximately three
hundred U. S. Navy buildings located in a humid
climate. In the course of this work humidity
related problems were found in many of the
buildings.
Face & bypass control is suggested as one of
the best methods of achieving passive humidity
control under common difficult part load conditions. However, some conditions cannot be handled
without additional measures. This paper explores
techniques, other than reheat, as means for improving
space comfort conditions under the worst
conditions.
It is shown that pre-cooling or desiccant
dehumidification of ventilation air can offer
substantially improved performance, especially in
conjunction with varying the ventilation air quantity as a percentage of supply air
