Abstract

A refrigerated display cabinet (10) which is provided with air circulation mechanism is disclosed. The air circulation mechanism comprises at least two air passageways (15a, 15b, 15c) defined on bottom portion of interior space of the cabinet (10), and blower fan (17a, 17b) placed on each air passageway (15a, 15b, 15c). An evaporator (16) of refrigeration unit is disposed on one of air passageway (15c) for cooling the air passed therethrough. The operation of fan (17a, 17b) in each air passageway (15a, 15b, 15c) is individually controlled to continue the air circulation within the interior space of cabinet (10), even if the refrigeration unit stopped its operation.
