A refrigerator includes a cabinet, a thermoelectric element module, a support disposed at a lower surface of the cabinet, and a heat dissipation cover coupled to a rear side of the cabinet. The thermoelectric element module includes a thermoelectric element including a heat absorption portion and a heat dissipation portion, a first heat sink contacting the heat absorption portion, a first fan facing the first heat sink, a second heat sink contacting the heat dissipation portion, a second fan exposed to an outside of the heat dissipation cover, and an insulating member between the first heat sink and the second heat sink. The heat dissipation cover is configured to guide air from the second fan in a vertical direction, and the support defines an air passage between the lower surface and a floor to allow air to be discharged to a front side through a lower side of the cabinet.

A merchandiser including a case that has an air inlet and defines a product display area with a customer access opening. The merchandiser also includes a canopy that has a first air outlet and a second air outlet, a first passageway connecting the air inlet with the first air outlet to direct a first airflow through the first air outlet at least partially across the opening to define a primary air curtain, and a second passageway in fluid communication with a HVAC system by ducting coupled between the merchandiser and the HVAC system to direct a second airflow defining a secondary air curtain from the HVAC system through the second air outlet at least partially across the opening. The primary and secondary air curtains cooperate with each other to minimize infiltration of ambient air into the product display area.
