ABSTRACT:
An air conditioning system is provided which utilizes both exhaust and outside air energy to regenerate the latent and sensible heat removal operations while not detrimentally increasing the bacterial contamination risks associated with exhaust air energy recoupment. The air conditioning system includes a supply air passageway through which supply air flows during conditioning thereof and a desiccant wheel for reducing the humidity of supply air in the supply air passageway. The system also includes separate exhaust air and outside air passageways. A first circulation assembly is provided for circulating a heat transfer medium between a refrigerant-type cooling assembly and a first transfer zone disposed in the exhaust air passageway and a second circulation assembly is provided for circulating a heat transfer medium between the cooling assembly and a second transfer zone disposed in the outside air passageway. Since the exhaust air is not mixed with the outside air, the outside air can be used to regenerate the desiccant wheel during its movement through the second heat transfer zone without risk of harmful bacterial growth promotion associated with the use of exhaust air in direct contact with the supply air.
