MULTI-TEMPERATURE TRANSPORTATION REFRIGERATION SYSTEM

摘要

A transportation refrigeration system includes an enclosure, and at least two compartments within the enclosure to be conditioned to two distinct temperatures. A refrigeration is circuit associated with each of the at least two compartments. A first refrigeration circuit includes a first compressor, a first evaporator, and a first expansion valve. A second refrigeration circuit includes a second compressor, a second evaporator, and a second expansion valve. The first and second refrigeration circuits utilize a common condenser, with first inlets into the condenser from the first circuit connected to a first flow passage and second inlets from the second circuit connected to second flow passages. First and second outlets are connected to the first and second flow passages. The first and second flow passages are staggered in a direction perpendicular to a flow passage across the condenser. A heat exchanger is also disclosed.
