device under conditions which reduce its moisture content and increases its temperature 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 provided by the exhaust air from the space and using the condensing coil of the refrigerant system to increase the regeneration air stream temperature the thus heated regeneration air stream is then passed through another segment of the rotating desiccant wheel to regenerate the wheel and is exhausted to the atmosphere application_number US 74543309 A description referring now to the drawing in detail and initially to fig7 an air conditioning system 10 according to one embodiment of the invention is illustrated in which a stream of ambient air 12 is treated to desired temperature and humidity conditions for use in a room enclosure or space 14 in the illustrative embodiment the system is used in areas where the ambient outside air has a high temperature and high humidity content or ratio as described above fig7 is a schematic drawing and it will be understood by those skilled in the art that the described air streams are contained in appropriate duct work and moved with appropriate fans which are not illustrated as seen in fig7 fresh outdoor ambient supply air 12 is first passed through a section 13 of an.
