1. A vapor compression system comprising:
a compressor configured to circulate a working fluid and operate at a plurality of operating conditions;
an evaporator in fluid communication with the compressor, the evaporator comprising:
a shell configured to allow the working fluid to flow therethrough and including at least two inlets, and at least one outlet;
a plurality of parallel-spaced tubes disposed within the shell, the plurality of parallel spaced tubes configured to allow a heat transfer fluid to flow therethrough; and
at least one baffle operably coupled to the plurality of parallel-spaced tubes, the at least one baffle configured to divide the shell into at least two chambers;
an expansion valve assembly in fluid communication with the evaporator the expansion valve assembly comprising:
a conduit operably coupled to each of the at least two inlets, respectively; and
a valve operably coupled to each conduit; and
a control device operably coupled to the compressor and the expansion valve assembly, the control device configured to operate the expansion valve assembly based at least in part on the plurality of operating conditions.
