Benefits of technology

The present application provides a refrigerated display case that includes a refrigeration component, an air plenum, and a shelf with a tank containing phase change material. The case has multiple temperature zones for for shelves and a uniform temperature across the shelf. The technical effect of this invention is to improve the efficiency of refrigerated display cases by maintaining a consistent temperature across the shelf and reduced energy consumption.

Problems solved by technology

Such a configuration, however, may not provide for a substantially homogenous temperature distribution from the back to the front of the product shelves.
Similarly, such a configuration may not allow for different temperature regions within a single case.

Embodiment Construction

[0015]Referring now to the drawings, in which like numerals refer to like elements throughout the several views, FIG. 1 shows an example of a refrigerated display case 10. In this example, the refrigerated display case 10 may be in the form of a reach-in cooler 15. FIG. 2 shows an example of the refrigerated display case 10 in the form of a multi-deck cooler 20. In both examples, the refrigerated display case 10 may be substantially modular and may extend to any suitable length. The refrigerated display case 10 may define a refrigerated space 25. Any type or number of refrigerated or frozen products may be positioned within the refrigerated space 25. The refrigerated display case 10, and the component thereof, may have any suitable size, shape, or configuration. Other types of refrigerated display cases 10 may be used.

[0016]In the case of the reach-in cooler 15, the refrigerated display case 10 also may include a number of door panels 30. The door panels 30 may have any suitable siz...

Abstract

The present application provides a refrigerated display case. The refrigerated display case may include a refrigeration component, an air plenum in communication with the refrigeration component, a shelf in communication with the air plenum, a phase change material tank positioned about the shelf, and a phase change material positioned within the phase change material tank such that a substantially uniform temperature is maintain across the shelf.

Description

TECHNICAL FIELD[0001]The present application and the resultant patent relate generally to modular refrigeration systems and more particularly relate to a refrigerated display case with temperature controlled shelves using a phase change material for a substantially uniform temperature distribution thereacross.BACKGROUND OF THE INVENTION[0002]The modern supermarket may have any number of refrigerated display cases to store and display different types of frozen and refrigerated products. Many different types of refrigerated display cases may be used, including multi-deck coolers, reach-in coolers, and the like. Refrigerated display cases generally are modular in nature such that a number of individual units may be combined to create a display case of any suitable size or length.[0003]Generally described, the products in a refrigerated display case are refrigerated based on (1) an airflow distribution from the rear wall of the case towards the front and (2) an air curtain extending dow...
