Patent ID: 8910488

Claim:
A refrigerated case comprising: a housing including an interior display volume; and a heat exchanger including a plurality of heat exchanger circuits that define a first number of tube passes, and at least one reheat circuit that defines a second number of tube passes, the second number of tube passes being greater than the first number of tube passes wherein the refrigerant in the at least one reheat circuit heated to a higher temperature than refrigerant in the heat exchanger circuits, the heat exchanger also including at least one reheat tube, and a connecting tube fluidly connecting the at least one reheat circuit with the at least one reheat tube, wherein the higher temperature refrigerant flows from the at least one reheat circuit of the heat exchanger section, through the connecting tube and then through the reheat tube, wherein an airflow flows over the plurality of heat exchanger circuits and the at least one reheat circuit and rejects heat to a refrigerant flowing therethrough to heat the refrigerant, and the airflow accepts heat from the higher temperature refrigerant that flows through the at least one reheat tube.
