A method and apparatus for conditioning air for an enclosure is disclosed in which a supply air stream, preferably from the atmosphere is cooled by the cooling coil of a refrigerant cooling system to reduce the temperature and humidity thereof to first predetermined level. The thus cooled and dehumidified air is then passed through a segment of a rotating desiccant wheel under conditions which reduce moisture content and increase temperature to a second predetermined temperature range. The supply air is then delivered from the desiccant wheel to the enclosure. The desiccant wheel is regenerated by heating a separate regeneration air stream, also preferably from the atmosphere, using the condensing coil of the refrigerant system in order to increase the regeneration air stream temperature to a third predetermined temperature range. The thus heated regeneration air stream is then passed through another segment of the rotating desiccant wheel to regenerate the wheel.
A method for conditioning air for an enclosure comprising the steps of cooling a supply air stream with a refrigerant system cooling coil to reduce the temperature thereof to a first predetermined temperature range, passing the thus cooled supply air stream through a segment of a rotating desiccant wheel under conditions which increase its temperature to a second predetermined temperature range and reduce its moisture content to a predetermined humidity level;
An apparatus for conditioning air for an enclosure comprising a refrigerant cooling system including a cooling coil, a condensing coil and a compressor, a rotatable desiccant wheel, means for drawing a supply air stream over the cooling coil of the refrigerant system to reduce its humidity and its temperature to a first predetermined temperature range and to pass the thus cooled supply air stream through a segment of the rotary desiccant wheel thereby to increase the air stream's temperature to a second predetermined temperature range while reducing its moisture content to a predetermined humidity level and then delivering the thus heated supply air to the enclosure;
