ABSTRACT:
A refrigerated show case has a cold air flow circulated along its bottom wall, rear wall and top wall and across its front opening between an ejection port and a suction port disposed along the upper and lower edges, respectively, of the front opening to refrigerate the interior of the show case. There are provided a by-pass port in the top wall for by-passing a part of the cold air flow, a heat-exchanger disposed on the top wall and communicated with the by-pass port, and an ejection port of a moderated air flow communicated with the heat-exchanger and disposed outside of and in parallel to the ejection port of the cold air flow, the moderated air flow being formed from the by-passed cold air flow by heat-exchange with a hot ambient air above the refrigerated show case through the heat-exchanger.
