Desiccant HVAC systems remove moisture from outdoor ventilation air before it enters a conditioned space. A wheel that contains a desiccant turns slowly to pick up humidity from incoming air and discharge that humidity to the outdoors. A desiccant system can be combined with a conventional air conditioning system in which the desiccant removes humidity and the air conditioner lowers air temperature. Desiccant materials can be dried, or regenerated, by adding heat.
