The present disclosure provides a system (10) for conditioning a gaseous supply stream. The system includes a desiccant-free heat and moisture exchange wheel (12) that efficiently transfers both heat and moisture between a warmer, substantially saturated gaseous exhaust stream (24) and a gaseous supply stream (20) such that the supply stream becomes heated and substantially saturated. The presently disclosed system therefore allows the use of a desiccant-free heat and moisture exchange wheel in applications requiring the transfer of both heat and relatively large amounts of moisture between counter-flowing air streams. The present wheel is designed in accordance with the present disclosure to transfer moisture through a process of condensation and re-evaporation, and provides the benefits of being generally easier and less expensive to manufacture than an enthalpy wheel, since an enthalpy wheel requires a coating of desiccant over its sensible heat exchange media. |
