ABSTRACT:
A combined refrigerated display case and walk-in cooler wherein an improved refrigeration system combines a single air circulation means and two distinct refrigeration units, a first refrigeration unit dispersing refrigerated air for a plurality of air curtains travelling across an access opening provided at the front of the display case portion of the combination, a second refrigeration unit dispersing refrigerated air rearwardly to the walk-in cooler portion of the combination. The front access opening provides unimpeded access to the refrigerated space of the display case. Support means are provided between the walk-in cooler portion and display case portion extending between a lower surface of the refrigeration system and the floor for carrying shelves associated with the refrigerated display case portion of the combination. Goods may be removed from the shelves by purchasers through the display case access opening and goods may be deposited thereon by suppliers through a rear access opening between the display case portion and the refrigerated walk-in cooler portion of the combination. A barrier such as a curtain or other protective means is also provided between the refrigerated display case portion and the walk-in cooler portion of the combination to environmentally separate the two sections or portions during normal usage. The refrigerated air forming the curtains in front of the refrigerated display space is recirculated into the walk-in cooler space after passing under the refrigerated display space.
