Benefits of technology

[0011] In accordance with one aspect of the invention, there is provided a modular refrigeration unit for use in an accessible compartment of a cooler. The modular refrigeration unit includes a wire-frame support, a dividing wall mounted to the wire-frame support, a gas cooler assembly mounted to the wire-frame support on one side of the dividing wall, and an evaporator assembly mounted to the opposite side of the dividing wall. The wire-frame support includes a forward portion that provides a convenient gripping location such that the modular refrigeration unit can be easily installed into and removed from the accessible compartment by an operator lifting and manipulating the modular refrigeration unit by the gripping location.

Problems solved by technology

This “split system” has inherent disadvantages which are apparent during assembly and servicing of the cooler cabinet.
Similarly, when a cooler which has been in use is found to be defective, the cooler must be put out of service in order to carry out the appropriate repairs.

Embodiment Construction

[0027] Referring to FIGS. 1 and 2, a merchandising display cooler 10 made in accordance with the invention comprises a cabinet 14 having a top wall 18, back wall 22, right side wall 26, left side wall 30, and bottom wall 34. An insulated interior floor 38 is vertically spaced from the bottom wall 34 so as define an accessible compartment 42 accommodating a refrigeration unit 46 (see FIGS. 3-7). A transparent door 50 is hinged to one of the side walls 26, 30 and covers the front opening of the cabinet 14. A peripheral seal 54 is mounted to the door 50 to keep the interior of the cabinet 14 airtight.

[0028] In the accessible compartment 42, the bottom wall 34, interior floor 38, and side walls 26, 30 each include a respective raised portion 58 that extends inwardly from the walls 26, 30, 34, 38. An insulated dividing wall 62 includes a peripheral seal 66 (as shown in FIG. 3) that sealingly engages the raised portions 58 within the accessible compartment 42.

Abstract

A modular refrigeration unit for use in an accessible compartment of a cooler, a cooler comprising a modular refrigeration unit, and a method for a modular refrigeration unit. The modular refrigeration unit can include a gas cooler assembly mounted to a support and positioned on one side of a dividing wall, and an evaporator assembly mounted to the dividing wall and positioned on the opposite side of the dividing wall from the gas cooler assembly. The modular refrigeration unit can include CO2 refrigerant adapted to be circulated between the evaporator assembly and the gas cooler assembly.

Description

FIELD OF THE INVENTION [0001] This invention relates to a merchandising display cooler of the type used in convenience stores, snack bars and restaurants for storing and cooling drinks, particularly carbonated beverages provided in cans and bottles. More particularly, this invention relates to the refrigeration unit used for cooling the merchandiser and to the resultant air-flow distribution in the merchandiser. BACKGROUND OF THE INVENTION [0002] Typically, merchandising coolers have a vertical display area which is visible to the consumer through glass doors which may be hinged or which may slide for easy access to the display shelves positioned within the refrigerated compartment. The refrigerated compartment is cooled by a refrigeration unit typically consisting of an evaporator, a compressor, a condenser, and an expansion device (typically a capillary tube) arranged in a closed circuit refrigeration system and charged with a suitable refrigerant (e.g., R134a). [0003] Merchandisi...
