A refrigerated merchandiser includes a case, a first case section defining a first product display area and a first air passageway having a first airflow inlet, a first airflow outlet, and a second airflow outlet, and a second case section having a glass panel through which a second product display area is visible. Moreover, the refrigerated merchandiser includes a fan positioned in the first air passageway to generate an airflow that is separated into a first airflow portion and a second airflow portion at or upstream of an evaporator. The first airflow portion is configured to flow through the evaporator and through the first airflow outlet. The second airflow portion is configured to bypass the evaporator via a bypass channel and flow through the second airflow outlet. The second airflow outlet is oriented to direct the second airflow portion over an exterior of the glass panel.

Merchandiser

A refrigerated merchandiser including a case having a first case section. The first and second case sections define first and second product display areas. The first case section further defines an air passageway and the second case section includes a glass panel. The air passageway supports a fan and is in fluid communication with a first airflow inlet and a second airflow outlet. An airflow flows through the first airflow outlet toward the evaporator and a second airflow outlet in communication with the first airflow inlet via an evaporator bypass channel. A first airflow portion flows through the first airflow outlet and is cooled by the evaporator, and a second airflow portion flows through the second airflow outlet to bypass the evaporator and is uncooled by the evaporator. The second airflow outlet directs the second airflow portion over an exterior of the glass panel of the second case section.

A heat exchanger for a refrigerated merchandiser includes a fan housing having an asymmetrical configuration. The fan housing can include a first section with a first open outlet and a second section with a second open outlet. A first fan is positioned in the first section and configured to create a first airflow through the first open outlet. A second fan is positioned in the second section and configured to create a second airflow through the second open outlet. An evaporator is in fluid communication with the first open outlet and second open outlet. The first section is asymmetrical about a first section central axis and the second section is asymmetrical about a second section central axis.

Merchandiser with even distribution fan plenum

A refrigerated merchandiser is provided including a case having a first case section. The first case section defines a first product display area and an air passageway. The air passageway supports a fan and is in fluid communication with an airflow inlet and an airflow outlet. The air passageway is at least partially defined by a refrigeration system including an evaporator. A portion of the air passageway is further defined by a plenum having a stepped profile configured to channel and adjust a direction of an airflow within the first air passageway prior to entering the evaporator. The refrigerated merchandiser may further include a second case section defining a second product display area and including a glass panel. A first airflow portion of an airflow is configured to flow through the airflow inlet toward the evaporator and a second airflow portion is configured to flow through a second airflow outlet via an evaporator bypass channel. The first airflow portion is cooled by the evaporator and the second airflow portion is uncooled by the evaporator. The second airflow portion may be further directed through the second airflow outlet over an exterior of the glass panel of the second case section.
