Multi-temperature transportation refrigeration system

A transportation refrigeration system comprising:

• an enclosure, and at least two compartments within said enclosure to be conditioned to two distinct temperatures;
• at least two refrigeration circuits, with a refrigeration circuit associated with each of said at least two compartments, and a first of said at least two refrigeration circuits including a first compressor, a first evaporator, and a first expansion valve, and a second of said at least two refrigeration circuits including a second compressor, a second evaporator, and a second expansion valve;
• and
• said first and second refrigeration circuits utilizing a common condenser, with first inlets into said condenser from said first circuit connected to a first flow passage and second inlets from said second circuit connected to second flow passages, and first and second outlets connected to said first and second flow passages, and said first and second flow passages staggered in a direction perpendicular to a flow passage across said condenser.
