A method and apparatus for a retrofit energy device and system to modify, manipulate and optimize airflow in vertical open-case refrigeration units. An open refrigerated display case includes a refrigerated display area comprising one or more shelves, an air outlet and an air inlet opening into the display area and spaced from one another, and a duct configured to direct air flow out of the air outlet across the display area and toward the air inlet to form an air curtain across the display area, each one or more shelves provided

A cold food display unit includes a well defining a receptacle, an insert positioned within the receptacle, a refrigeration system, a first cooling air discharge, and a second cooling air discharge. The insert is positioned within the receptacle to form a first cooling air flow path and a second cooling air flow path. The refrigeration system includes a cooling air outlet positioned within the receptacle to provide cooling air to the first and second cooling air flow paths. The first cooling air discharge discharges a first flow of cooling air toward the second side of the well, and the second cooling air discharge discharges a second flow of cooling air toward the first side of the well.

The present disclosure provides an improved food preparation table. Cooled air is passed over the top of each food pan individually, preventing the food from spoiling at high ambient temperatures. The sides of the food pans are also cooled at the same time.

A refrigerated food preparation table includes a housing defining both (i) an upper food preparation holding area with food pan receiving locations and (ii) a food compartment. A cooling system includes a cooling air flow path with a first region for delivering cooling air at least one of below or alongside food pans in the upper food preparation holding area and a second region, downstream of the first region, for delivering at least a portion of the cooling air into the food compartment after the portion of the cooling air has passed below or alongside food pans in the upper food preparation holding area. The cooling air flow path includes a third region, upstream of the first region, and an openable/closeable path portion into the food compartment from the third region for selective delivery of at least some cooling air from the third region into the food compartment.

The present invention provides a merchandiser including a case defining primary and secondary air passageways, a first fan, and an evaporator. The case includes a base having first and second air inlets, one or more walls, and a canopy cooperatively defining a product display area accessible through an opening. The evaporator is disposed in the base. A first fan is disposed in the case and generates a primary airflow through the primary air passageway. The first fan, or a second fan, generates a secondary airflow through the secondary air passageway. Air from the product display area, air outlet, or both entering the first air inlet at least partially defines the first airflow which flows through the evaporator via the primary air passageway. The secondary airflow flows through the evaporator and is at least partially defined by air flowing past the first air inlet and entering the second air inlet.
