ABSTRACT:
A transport refrigeration unit having a top and bottom, a back, and side planes which include a front and first and second sides. The transport refrigeration unit further includes a condenser having air intake openings along a selected side plane of the unit, with condenser air being discharged through the top. A sound reducing cover is disposed to surround the transport refrigeration unit. The sound reducing cover is lined with a sound absorbing material, and it re-positions the condenser air intake such that incoming condenser air enters the unit through the top, instead of through a side plane, while maintaining top air discharge. In one embodiment the sound reducing cover separates incoming and exiting air in a direction from the front to the back of the unit, and in another embodiment in a direction from one side of the unit to the other side.
