An open display refrigerator comprises a refrigerated interior space, air in the refrigerated interior space being separated from air exterior to the open display refrigerator by an air curtain established by a fan which blows air through an air outlet towards a corresponding air inlet which recovers air from the air curtain for recirculation to the air outlet. A distal region of the air outlet is occluded to leave only a region of the air outlet proximal to the interior space open, and an air curtain guide is aligned in a direction of air flow of the air curtain with an edge of the blanking plate proximal to the interior space.

An air curtain guide mounting kit for attaching an air curtain guide to an open-display refrigerator, the kit comprising: an arm adapted to be mounted to the refrigerator; and a bracket comprising an engagement section adapted to be connected to an air curtain guide, and a mounting section connected to the engagement section and adapted to form a hinged connection with the arm.

A refrigerated display cabinet includes a housing surrounding a plurality of shelves, a cabinet tank arranged beneath the plurality of shelves and a backwall channel positioned behind the plurality of shelves. The cabinet tank and the backwall channel cooperate to define an air passage. A micro-channel heat exchanger and a fan are arranged within the air passage. The fan being operable to move a flow of air through the heat exchanger. The fan is one of a cross-flow fan and a mixed-flow fan. The heat exchanger is arranged within the air passage at an angle between about 20 degrees and about 80 degrees or between about 100 degrees and about 160 degrees relative to the flow of air.

A refrigerator has an open front, an air curtain system having at least one upper air egress having an outer edge and at least one lower air-recovery ingress. The air curtain system is adapted to produce a substantially vertical air curtain over at least part of the open front of the refrigerator. The refrigerator has a plurality of shelves between the egress and the ingress a plurality of shelves between the egress and the ingress including a first shelf that has an aerofoil positioned in front of it, the first shelf being located in the upper half of the open front of refrigerator. The refrigerator also includes a second shelf that does not have an aerofoil positioned in front of it, the second shelf being located below the first shelf.

A refrigerated display cabinet includes a refrigeration loop including a compressor, a condenser, a throttling element and an evaporator; a main body comprising a storage space, the evaporator is for cooling the storage space and at least one of the compressor, condenser and throttling element are located outside of the storage space; and a fan arrangement located outside of the storage space, configured to direct air to disperse any build-up of gases located in a region surrounding the bottom of the refrigerated display cabinet.

A refrigerator has an open front and an air curtain system having at least one upper air egress with an outer edge and at least one lower air-recovery ingress. The air curtain system is adapted to produce a substantially vertical air curtain over at least part of the open front of the refrigerator. The refrigerator comprises at least one shelf between the egress and the ingress, the shelf having a front edge, and at least one elongate air-guiding strip extending across at least part of the open front of the fridge. The strip is located substantially in the plane of the shelf and spaced from the front edge of the shelf. The strip is located substantially vertically beneath the outer edge of the upper air egress.

The present invention provides an open display refrigerator comprising: a refrigerated storage space, air in the refrigerated storage space being separated from air exterior to the open display refrigerator by an air curtain established by a fan which blows air towards an air outlet, air in the air curtain being recovered by an air inlet which recirculates the air from the air curtain into an air duct coupled to the air outlet, and an air guide coupled to the air outlet or air duct and extending from the air outlet such that it bypasses a portion of a void between the uppermost shelf and the air outlet, whereby the air curtain is established between an extremity of the portion of the void proximal to the air inlet and the air inlet.

A bracket (100) for clamping an aerofoil to a shelf (102) of a refrigerator is described. Bracket (100) comprises a mounting portion for holding part of an aerofoil in use, an upper jaw (104) configured to engage the forward lip (106) of shelf (102) and a lower jaw member (108) configured to engage a lower lip (112) on the underside (110) of refrigerator shelf (102). The bracket (100) may also comprise clamping means shown generally by (114) configured to enable the upper jaw member (104) and the lower jaw members (108) to be drawn towards one another to clamp the bracket (100) on the refrigerator shelf (102).

The provides disclosure describes a method for configuring an open display refrigerator, the method comprises: a measuring an initial temperature difference between the warmest temperature recorded by an array of temperature sensors and the coldest temperature recorded by the array of temperature sensors; coupling an air guide to at least one shelf; adjusting the distance between the air guide and the edge of the shelf for the at least one shelf; measuring a final temperature difference associated with the distance, the final temperature difference being the temperature difference between the warmest temperature recorded by the array of temperature sensors and the coldest temperature recorded by the array of temperatures sensors after coupling an air guide to the at least one shelf; selecting a distance from the plurality of distances that gives rise to at least a threshold temperature difference, or selecting the distance from the plurality of distances wherein the difference between the initial temperature difference and the associated final temperature difference is greatest.

A refrigerated display cabinet of vertical or semi-vertical type has a containment structure defining a display compartment and an access opening, a main air inlet mouth and a main air outlet mouth being in communication with the display compartment. A channel connects the main air inlet and outlet mouths to direct a refrigerated air flow towards the main air inlet mouth in the form of an air curtain. The display compartment is divided into an upper area having one or more shelves and a lower area adapted to be loaded with products. One shelf separating the lower and upper areas is a blowing shelf having an internal conduit directing the refrigerated air flow in the display compartment through a secondary air-emitting mouth, a first deflector intercepting the refrigerated air flow which forms the air curtain and a second deflector intercepting the refrigerated air flow emitted by the blowing shelf.
