A regenerator energy exchange device (10) comprises an energy recovery wheel (14) having interchangeable segments (14a, 14b) of a heat and moisture exchange matrix material. Each segment may include one or more desiccants having different moisture adsorption characteristics deposited thereon. Alternatively, the energy recovery wheel may contain a matrix which is uniformly coated with at least two different desiccants. In another embodiment, the wheel may have zones (29, 30) of different desiccants or desiccant combinations which are arranged in series in the direction of air flow through the matrix to provide different moisture adsorption characteristics along the air flow path. The zone (29) closest to a highly humid airstream may contain, for example, a type 5 desiccant, while the zone (30) closest to a conditioned exhaust airstream may contain a type 3 desiccant. All configurations are designed to increase the effectiveness over the middle to high range of relative humidities. |
