Abstract:
1. A method for condition air for supply to an enclosure comprising the steps of cooling a supply air stream having a temperature range of between 65° F.–95° and above and a moisture content of between 90–180 gr/lb. with a refrigerant system cooling coil to reduce the moisture content and temperature thereof to a first predetermined moisture content saturation level and saturation temperature range, passing the thus cooled and dried ambient supply air stream through a segment of a rotating desiccant wheel under conditions which increase its temperature to a second predetermined temperature range of about 68–81° F. and reduce its moisture content further to a predetermined humidity level of between 30–80 gr/lb.; and then delivering the thus treated air to said enclosure; regenerating the desiccant wheel by heating a regeneration air stream with the condensing coil of the refrigerant system to increase its temperature to a predetermined temperature range of 105° F.–135° F. and then passing the heated regeneration air stream through another segment of the rotating desiccant wheel to regenerate the desiccant in the wheel; sensing at least one condition of the supply air stream, the regeneration air stream and/or the refrigeration system; and controlling the output of the compressor in response to the sensed condition.
