A heat exchanger for a temperature controlled case is disclosed herein. A temperature controlled case includes a housing that defines a temperature controlled space. The housing includes a duct that receives circulated air. A heat exchanger is coupled to the housing and disposed within the duct. The heat exchanger includes an intake face at a non-perpendicular angle relative to an air flow direction in the duct immediately upstream of the heat exchanger.

A preferred embodiment utilizes the waste heat from a refrigerant cycle to aid in the removal of condensate from a refrigerated case used primarily by grocery stores. Certain embodiments use a heating element to boil off condensate or a pump to remove the condensate. Another embodiment utilizes a wicking element and a shroud that directs hot air from the condenser through the wick thereby increasing the condensate evaporation rate. Yet another embodiment utilizes the hot gas tube from the refrigeration system routed through the bottom of the condensate tray to pre-heat the condensate to accelerate evaporation. Alternative embodiments combine certain features to create even more efficient system such as a heating element used with the wick system or the hot gas system used with the wick system. In some embodiments, a mold and mildew inhibitor is added to the condensate to maintain cleanliness.

The device is a cooling appliance with a cooling chamber that includes a top assembly with a top, rear, and bottom; a rear wall assembly and a bottom assembly. The bottom assembly is supported by vertically adjustable front and rear feet. The front and rear feet include a vertical adjustment mechanism that is accessible from above and are vertically adjustable from above through the bottom assembly.

A fan plenum for a refrigerated merchandiser, in which the refrigerated merchandiser includes a case defining a product display area and a lower flue, a first air passageway, and a second air passageway, and in which the first air passageway and second air passageway are in fluid communication with the lower flue and with the product display area, includes a top wall including a fan aperture for receiving a fan having a plurality of fan blades. The fan plenum further includes a side wall and a plenum base. An airflow divider partitions the fan plenum into a first duct and a second duct. The first duct is fluidly couplable with the first air passageway and the second duct is fluidly couplable with the second air passageway.

A refrigerated display unit is described which comprises at least one refrigerating machine; at least one refrigerated volume designed to contain products to be kept at a temperature lower than the room temperature by means of the refrigerating machine; at least one technical volume intended to contain an air treatment unit, operatively connected to the refrigerating machine and comprising at least one heat exchange battery, through which a refrigerating fluid and a carrier fluid exchange heat, and a plurality of fans placed at the inlet surface of the heat exchange battery; one or more doors or walls that isolate the refrigerated volume from the external environment; one or more conduits of an air system, placed in fluid connection with the heat exchange battery and arranged for conveying the refrigerated carrier fluid, moved by the fans, towards the refrigerated volume.

A refrigerated display case includes an air director that directs air with less turbulence in a resultant air curtain but also allows for the convenient removal of an air filter member by using a flexible hinge on a portion of the air deflector. Other embodiments are disclosed as well.

An air circulation and ventilation system for a retail store produce display comprises an air flow system that outputs an air flow to the produce display; a sensor system that determines a condition of the produce in the produce display; a sensor controller that controls the air flow system to change the air flow in the produce display in response to the condition of the produce in the produce display; and a self-contained power panel for powering the air flow system and the sensor system.

A refrigerated merchandiser including a case having a first case section. The first and second case sections define first and second product display areas. The first case section further defines an air passageway and the second case section includes a glass panel. The air passageway supports a fan and is in fluid communication with a first airflow inlet and a second airflow outlet. An airflow flows through the first airflow outlet toward the evaporator and a second airflow outlet in communication with the first airflow inlet via an evaporator bypass channel. A first airflow portion flows through the first airflow outlet and is cooled by the evaporator, and a second airflow portion flows through the second airflow outlet to bypass the evaporator and is uncooled by the evaporator. The second airflow outlet directs the second airflow portion over an exterior of the glass panel of the second case section.

Systems and methods for deploying a defrost heater include a rod heater bracket including a body including a first edge and a second edge opposite the first edge. The bracket includes at least one L-shaped slot formed in the body, the L-shaped slot including an opening along the first edge, and a groove located adjacent to the second edge and configured to retain at least a portion of a rod heater adjacent an evaporator of a refrigerated display case. The rod heater bracket includes a tab configured to adjust between an open position to allow access to the groove through the second edge and a closed position to block access to the opening between the second edge and the groove.
