Abstract
An illustrative example embodiment of a transport refrigeration system includes an evaporator air management system having an evaporator heat exchanger and an air passage downstream of the evaporator heat exchanger. A two-stage fan assembly within the air passage includes a first fan stage having a first fan rotor, a first motor associated with the first fan rotor for selectively causing the first fan rotor to rotate in a first direction about a fan axis, a second fan stage having a second fan rotor in series with the first fan rotor, and a second motor associated with the second fan rotor for selectively causing the second fan to rotate in a second, opposite direction about the fan axis. The first and second fan stages draw air across the evaporator heat exchanger and through the air passage.
