Patent ID: 8769970

Claim:
A refrigerated case comprising: a housing containing an interior volume for storing items; an air inlet; an air flow path extending from the air inlet; a fan positioned to drive an air flow along the air flow path; an air outlet along the air flow path positioned to discharge cold air to cool the interior volume; a refrigerant-to-air heat exchanger disposed along the air flow path, and a refrigerant flow path having at least a portion that extends through the heat exchanger; and an expansion device along the refrigerant flow path, wherein: along the air flow path, the heat exchanger has a preconditioning section, an evaporator section, and a reheat section, the evaporator section downstream of the preconditioning section and upstream of the reheat section; and along the refrigerant flow path, the preconditioning section is upstream of the reheat section, and the reheat section is upstream of the evaporator section and the expansion device is downstream of the reheat section and upstream of the evaporator section; and in the reheat section the refrigerant flow path is defined by reheat tube sections that are disposed adjacent to the top of the heat exchanger with the refrigerant configured to flow from the preconditioning section to an upper most one of the reheat tube sections and then toward a lower most one of the reheat tube sections.
