Each channel 390 may include an angled entrance 550 leading to an enclosed end 560. The channels 390 may be used with the product shelves 160. In this example, a product shelf 570 may include a shelf panel 580 supported by an angled support bracket 590. The shelf panel 580 may extend into a mounting flange 600. The mounting flange 600 may be positioned within the angled entrance 550 and then into the enclosed end 560 of the channel 390 of the slat wall 380. The angled support bracket 590 then supports the shelf panel 580 against the slat wall 380. The channels 390 may have any size or shape and may have other configurations. The product shelf 570 may have other sizes, shapes, and configurations. Other components and other configurations may be used herein. The slat wall 380 thus allows differing and changeable configurations of product shelves 570 and the like thereon.

(49) In addition to the product shelves 160 and product bins 170 positioned about the slat wall 380, other types of shelving may be used herein with the multi-deck refrigerated merchandising cases 120 or any of the refrigerated merchandising cases 110. For example, shelf rails 610 also may be used. As is shown in FIGS. 12 and 13, the shelf rails 610 may include a number of roller channels 620 and support apertures 630. The shelf rails 610 may have any size, shape, or configuration. Alternatively, the channels 390 of the slat wall 380 may be used as the roller channels 620 without the use of the shelf rails 610 and the like. The shelf rails 610 and/or the roller channels 620 may run in a vertical and/or horizontal fashion and/or at any angle therebetween. The shelf rails 610 and/or the channels 620 may be used with a number of product shelves 640. The product shelves 640 may have any size, shape, or configuration. In this example, the product shelves 640 may include a shelf panel 650 and an attachment bracket 660. The attachment bracket 660 may include a roller 670.

The attachment prongs 680 may be sized to fit within the support apertures 630 of the channels 620. The product shelves 640 thus may be maneuverable in any direction as the roller 670 maneuvers within the roller channels 620. The product shelf 640 then may be secured in place by positioning the attachment prong 680 within the support apertures 630. Other components and other configurations also may be used herein.

(50) Other product variations include slide out product shelves 690. As is shown in, for example, FIGS. 13 and 14, the shelf panel 650 may have a number of panel rollers 700 that fit within an outer rail slot 710. The slide out shelves690 thus may allow the shelf panel 650 to maneuver within the outer rail slots 710 for ease of stocking and ease of cleaning A further alternative is the drop out shelf 720 of FIG. 15. In the case of the use of a perforated shelf panel 730, a lower panel 740 may be maneuverable such that the lower pane1740 may flip down so as to clean any collected debris and/or liquids. Other components and other configurations may be used herein.

(51) A further embodiment is a microclimate shelf 750 as is shown in FIG. 16. The microclimate shelf 750 may have a number of air slots 760 in communication with the air plenums 310. The use of the air slots 760 thus allows air to be distributed through the microclimate shelf 750 and over the products below. Moreover, as is shown in FIG. 17, an ethylene filter 770 also may be used to absorb ethylene gas so as to assist in keeping produce fresh. Other components and other configurations also may be used herein.

(52) Other alternatives for use with the multi-deck refrigerated merchandising case 120 and other types of refrigerated merchandising cases 110 may include the use of track lighting 780 as is shown in FIG. 18, the use of misters 790 as shown in FIG. 19, and the use of touch point indicators 800 as shown in FIG. 20.

The panels 860 and inner air plenums 870 may have any size, shape, or configuration. A number of deck pans 880 may be positioned within the base 830 and in communication with the inner air plenum 870. The deck pans 880 may form a lower plenum 890 in communication with the inner air plenum 870. As is shown in FIG. 24, the deck pans 880 may include a number of pan apertures 900. The pan apertures 900 may permit a flow of air to pass therethrough and create an air curtain effect in front of the glass doors 810 or elsewhere. The deck pans 880 and the pan apertures 900 may have any size, shape, or configuration.

(57) The reach-in refrigerated merchandising container 130 may be enclosed by a number of ceiling panels 910. The ceiling panels 910 may have any size, shape, or configuration. A number of cooling modules 920 may be positioned on the ceiling panels 910. The cooling modules 920 may include a number of evaporator coils 930 positioned within a drain pan 940. The evaporator coils 930 and the cooling modules 920 as a whole may have any size, shape, or configuration and/or capacity. The evaporator coils 930 may be in communication with the inner air plenum 870 and the lower plenum 890 so as to circulate a flow of cooling air throughout the reach-in refrigerated merchandising case 130. As is shown in FIGS. 25A-25C, the cooling modules 920 may have a number of different configurations. As is shown in FIG. 25A, each cooling module 920 may have one set of evaporator coils 930. Alternatively as is shown in FIG. 25B, a number of evaporator clusters may be used. As shown in FIG. 25C, a single evaporator section also may be used.

(58) As is shown in FIG. 27, each glass door 810 may include a glass panel 960 and a door frame 970. Any number of the glass doors 810 may be used herein in any size, shape, or configuration. The glass panel 960 may be made out of any type of insulated, transparent materials. The glass panel 960 may extend somewhat beyond the door frame 970 so as to give the illusion that the door frame 970 do not exist. Such positioning may increase the glass box like appearance of the reach-in refrigerated merchandising case 130 as a whole. Other components and other configurations may be used herein.

(59) As is shown in FIG. 28, a number of shelves 980 may be positioned within the reach-in refrigerated merchandising case 130. The shelves 980 may be attached to the frame members 850 by a number of quick disconnect pins 990.
