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.

Abstract: Transport refrigeration apparatus including a metallic frame having first and second upstanding end portions, an upstanding back portion, and a horizontally oriented portion which extends between the upstanding end portions and the upstanding back portion. The metallic frame includes first and second spaced end members each having first and second integral portions. The first integral portions form part of the upstanding back portion, and the second integral portions form the first and second upstanding end portions. The second integral portions function as support arms for refrigeration components of the apparatus, with each having a generally triangular configuration which includes a horizontally oriented lower side, a vertically oriented back side, and a flanged side. The flanged side includes a horizontally oriented lower portion which flares upwardly via a smoothly radiused intermediate portion to join an upper portion which slopes towards the vertically oriented back side.
