Abstract:
1. A transport refrigeration unit including a compressor, a primary refrigerant circuit including heat rejection heat exchanger downstream of said compressor, and a heat absorption heat exchanger downstream of said heat rejection heat exchanger, the transport refrigeration unit comprising: a barrier to separate a first portion of the transport refrigeration unit to operate in a refrigerated environment from a second portion; at least one damper door in the refrigerated portion, the damper door to move between three or more positions; and an actuator operatively coupled to move the damper door, the actuator controlling movement of the damper door between an open position and a closed position and a plurality of intermediate positions between the open position and a closed position; where the plurality of intermediate positions of the damper door are configured to vary a transport refrigeration unit capacity or a transport refrigeration unit humidity capacity.
