Abstract
A system (20) for conditioning air (30) includes conditioning circuits (26, 28). Each of the circuits (26, 28) includes a heat transfer coil (54, 60) residing in a supply section (22) of the system (20), and a heat transfer coil (56, 62) residing in a return section (24) of the system (20). A controller (50) in communication with the circuits (26, 28) determines one of a heating mode (78, 110) and a cooling mode (148, 150) for an interior space (34). The controller (50) selectively actuates the conditioning circuits (26, 28) to condition outside air (30) entering the supply section (22) to produce conditioned supply air (36) for provision into space (34) and to recover heating and cooling energy from return air (38) entering the return section (24) from the space (34) prior to its discharge from the system (20) as exhaust air (44). An additional cooling circuit (218) residing in a cooling section (214) pre-conditions outside air (30) by reducing the temperature of outside air (30) before supply section (22) of system (20) conditions outside air (30) for interior space (34).
