Problems solved by technology

However, backplane flow has the disadvantage that the coldest air blows on the coldest items behind the shelf, and these items get the lowest heat gain due to being furthest from the access opening
Specifically, wider aisles may be required in retail installations due to ergonomics related to general access as well as buyers opening doors and managing carts

Embodiment Construction

[0076] see first figure 1 , which shows a refrigerated display unit 1 according to the invention. Unit 1 is shown here in simple form as a discrete appliance capable of self-contained operation, but in practice a support structure (eg storage or display cabinet underneath) is required to raise such a unit to an easily access height. A number of such units 1 may be used in parallel, stacked in a modular fashion and / or distributed around a retail area to create larger refrigerated displays. The principle of how to create an integrated multi-cellular display device by modularizing a plurality of such units will be described below.

[0077] figure 1 The unit 1 shown in is generally in the form of a hollow cuboid or box comprising an insulating top wall 31 , bottom wall 33 , side walls 37 and a rear wall enclosing a correspondingly shaped product display space 3 (shown here as a shaded area). 35. exist figure 1 Shown on the right side of is a front access opening 39 defined b...

Abstract

A refrigerated display unit (1), having an open-fronted cabinet providing a product display space (3) accessible through an access opening (39) provided by the open front. Cooling means (27) produces cold air to refrigerate items in the product display space (3). A cold air curtain is provided across the access opening (39) using a forwardly-positioned discharge outlet (5) communicating with a supply duct (45) and a forwardly-positioned return inlet (7) in communication with a return duct (41 ) receiving air from the air curtain (9). The air curtain (9) is substantially unsupported by any supplementary cooling airflow supplied into the product display space (3) separately from the air curtain (9).

Description

technical field [0001] The present invention relates to refrigerated display equipment. In this specification, a refrigerated multi-layered display case or cabinet for refrigeration, display and retail of refrigerated or frozen food and beverage products as used in retail stores is exemplified. Background technique [0002] The present invention is not limited to retail food and beverage cabinets. For example, the principles of the invention can be used to display other items that require refrigeration, such as pharmaceuticals or scientific items that may be prone to degradation. However, the principles of the present invention are particularly advantageous for retail use. [0003] For up-close viewing and purchasing, front opening multi-level display cabinets provide hassle-free access to refrigerated items so that items on display can be easily seen, accessed and removed. Typically, such cabinets are cooled by a large downward jetting refrigerated air curtain extending f...
