Desiccant multi-fuel hot air/water air conditioning unit

An improved air conditioning system for admitting air from a space, adjusting the temperature and humidity of the air, delivering the adjusted air to an interior space of a structure, removal of exhaust air therefrom and return of the exhaust air to the space, comprising:

• a first path for conditioning air including a first air intake means for admitting air to be conditioned;
• an air supply first blower means communicating with said first air intake means for receiving, pressurizing and moving the air from said first air intake means;
• a desiccant means rotatable through a first zone and second zone, the first zone communicating with said air supply first blower means and receiving the pressurized exterior air from said exterior air supply first blower means for reducing the humidity by means of reducing the water vapor content of the air passing therethrough;
• a heat exchanger means having a first area for accepting heat and a second area for rejecting heat, wherein said first area of said heat exchanger means communicates with said desiccant means for receiving the air with reduced water vapor content from said desiccant means for downwardly adjusting the temperature of air displaced therethrough;
• a heating means communicating with said heat exchanger means for receiving the cooled reduced water vapor content air from said heat exchanger means for optionally upwardly adjusting the temperature of air displaced therethrough;
• a conditioned first air exit means communicating with said heating means for receiving the temperature and humidity adjusted air from said heating means and communicating with the interior space of a structure for delivery thereto;
• a second path independent of the first path for indirect evaporative cooling of air including a second air intake means for accepting air from a space with said second area of said heat exchanger thereadjacent wherein the accepted air passes over said second area and removes heat from said second area of said heat exchanger means;
• a second air blower means communicating with said second area for receiving and moving air from said second area of said heat exchanger means;
• a second air exit means communicating with said second air blower means for receiving second air from said second air blower means and communicating with the exterior of the structure for delivering of the second air thereto;
• a third path, independent of the first path and second path for regeneration of desiccant air including a third air intake means, a heater associated therewith and the second zone of said desiccant means wherein said desiccant means communicates with said regenerated third air intake means for regeneration of said desiccant means by transfer of water vapor and subsequent removal;
• and
• a third regeneration air exit means communicating with said second zone of said desiccant means for receiving regeneration air from said second zone of said desiccant means for delivery of the regeneration air thereto.
