    Abstract: A refrigerated merchandiser (100) includes an upright, open-front, insulated cabinet (110) defining a product display area (125) connected in airflow communication with a compartment (120) via an air circulation circuit (122, 114, 116). A high pressure drop evaporator (40) and a plurality of closely spaced fans (70) are disposed within compartment (120). The evaporator (40) is provided with a relatively high fin density heat exchanger coil providing a relatively high air side pressure drop through the evaporator. The increased flow resistance through the evaporator coupled with the plurality of closely spaced fans results in a substantially uniform evaporator outlet temperature profile across the length of the evaporator.

    Abstract: A refrigerated case includes a housing including an interior display volume and a heat exchanger. The heat exchanger includes a circuit defined by a heat exchanger section including a plurality of tubes that define a flow path, a reheat section including a reheat tube, and a connecting tube fluidly connecting the flow path of the heat exchanger section with the reheat tube. Air flows over the plurality of tubes of the heat exchanger section and rejects heat to a refrigerant flowing through the plurality of tubes to heat the refrigerant. The heated refrigerant then flows through the reheat tube. As the air passes over the reheat tube, the air accepts heat from the heated refrigerant flowing through the reheat tube.

    Abstract: A refrigerated merchandiser system (10) includes a compressor (20), a condenser (30), a display case (100) having an evaporator (40), an expansion device (50), and an evaporator pressure control device (60) connected in a closed refrigerant circuit via refrigerant lines (12, 14, 16 and 18). The evaporator pressure control device (60) operates to maintain the pressure in the evaporator at a set point pressure so as to maintain the temperature of the refrigerant expanding from a liquid to a vapor within the evaporator (40) at a desired temperature. A controller (90) operatively associated with the evaporator pressure control device (60) maintains the set point pressure at a first pressure for the refrigerant equivalent to a first refrigerant temperature during a first refrigeration mode and at a second pressure for the refrigerant equivalent to a second refrigerant temperature about 2 to about 12 degrees warmer than the first temperature during a second refrigerant mode. The controller (90) sequences operation between said first refrigeration mode and said second refrigeration mode.

    Abstract: A display case cools and displays products. A first fan system circulates cool air through the display case. The cool air is directed downwardly along a front of the display case to form a primary air curtain. A second fan system circulates ambient air to generate a secondary air curtain. The secondary air curtain is located between the primary air curtain and the outside environment, trapping the primary air curtain near an interior display volume of the display case. Each end of the second fan system is several inches shorter than the display case to allow for case to case attachment. The second fan system includes a louver near each of the side walls and a front of the second fan system. Each louver includes a plurality of slanted panels. The louvers direct the ambient air towards the side walls of the display case to improve the secondary discharge air velocity in a front corner area of the display case.

    Abstract: A refrigerated display case includes a heat exchanger with circuits that route secondary fluid in a counterflow direction with respect to the airflow through the heat exchanger. At least one circuit directs secondary fluid from the entrance end to the exit end of the heat exchanger to exchange heat with air exiting the heat exchanger. The higher fluid temperature raises the air dry bulb and lowers the air relative humidity to improve the capability of the air to absorb moisture in the display case.
