Innovative HVAC Cycles for Severe Part Load Conditions in the Humid Climate
MetadataShow full item record
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.
