## Abstract

A refrigerated air curtain redirection unit can be retro fitted to the front base of a an existing reach-in commercial open-display refrigerated cabinet, or provided as original built-in equipment for a newly manufactured cabinet to reduce refrigerated air spillage. The unit has a body part that protrudes outwardly of the open frontage of the cabinet at an upward angle and there is an inwardly curved part at its top region whereby an air vortex is formed that acts to draw air from the curtain at its base into an air duct of the cabinet.

## Claims

### Claim 1

Air-catching apparatus to limit air spillage from a refrigerated air curtain at the open frontage of a commercial refrigerated reach-in open-display cabinet, wherein the apparatus comprises an air-catching unit at the base of said frontage which protrudes at an angle outwards at the frontage, characterised in that the unit has a top region that is curved inwardly whereby an air vortex is created at said base which acts to direct air from the curtain into the cabinet.

### Claim 2 (depends on 1)

Air-catching apparatus according to claim 1 wherein the curved top region of the air-catching unit has a part-circular curvature.

### Claim 3 (depends on 1)

Air-catching apparatus according to claim 1 wherein the air-catching unit is elongate and has a fixing part along its bottom region, a flat body part between the bottom region and the curved top region, and transverse end parts at ends of the body part, the body part being at an angle to the fixing part.

### Claim 4 (depends on 1, 2, 3)

A refrigerated cabinet having an open frontage, internal shelving or decking, means for directing a curtain of refrigerated air from the top of the frontage down to the base thereof, air-recovery ducts in the cabinet to receive air from the said base, and an air-catching unit according to any one of claims 1 to 3 fixed along said base whereby the said air vortex acts to direct air from the curtain to the said ducts and thereby reduces spillage of such air.

### Claim 5 (depends on 4)

A refrigerated cabinet according to claim 4 wherein the air-catching unit is retrofitted to the cabinet and the unit protrudes outwardly from the frontage.

### Claim 6 (depends on 3, 5)

A refrigerated cabinet according to claim 5 when dependent on claim 3 wherein the body part and the curved region protrude wholly from the frontage.

### Claim 7 (depends on 4)

A refrigerated cabinet according to claim 4 wherein the air-catching unit extends along the entire length of the base.

### Claim 8 (depends on 5)

A refrigerated cabinet according to claim 5 wherein the air-catching unit extends along the entire length of the base.

### Claim 9 (depends on 6)

A refrigerated cabinet according to claim 6 wherein the air-catching unit extends along the entire length of the base.
