<p>A refrigeration display case (10) includes a display cabinet (12), a cooling duct (14), a refrigeration system, an air diffuser (16) and an air circulation system. The display cabinet has an inner volume (18) and an access aperture (20). The cooling duct has an airflow passage extending between an inlet (24) and an outlet (22), which inlet and outlet fluidly connect the airflow passage to the inner volume of the display case. The refrigeration system has an evaporator (44) disposed in the airflow passage. The evaporator has low and high temperature regions (54, 56). The air diffuser has a high airflow region (62) and a low airflow region (64). The high airflow region is configured to direct air toward the low temperature region. The low airflow region is configured to direct air toward the high temperature region. The air circulation system is adapted to circulate air between the cooling duct and the display cabinet.</p> |
