Abstract

A hybrid air-conditioning system (10) for a building space includes a first fan (56) for passing process air (51) from an ambient space through an evaporator coil (50) through a first zone (52a) of a rotatable moisture transfer wheel (52) and then through a first zone (54a) of a rotatable heat exchange wheel (54) to the conditioned space. A second fan (61) passes regenerative air (58) from the space through a second zone (54b) of the heat exchange wheel (54), through a condenser coil (60), through a second zone (52b) of the moisture transfer wheel (52) and then to the ambient space. The system (10) includes a compressor (66) having a suction side (66a) in fluid communication with a first side of the condenser coil (60). The second side (50b) of the evaporator coil (50) is in fluid communication with a second side (60b) of the condenser coil (60).
