연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

1. A fan plenum for a refrigerated merchandiser, the refrigerated merchandiser including a case defining a product display area and including a lower flue, a first air passageway, and a second air passageway, the first air passageway and second air passageway in fluid communication with the lower flue and with the product display area, the fan plenum comprising: an airflow divider to direct a first portion of an airflow to the first air passageway and to direct a second portion of the airflow to the second air passageway, wherein a proportion of air between the first portion and the second portion is a function of a position and geometry of the airflow divider,wherein the fan plenum includes a top wall, a side wall, and a plenum base, and wherein the airflow divider partitions the fan plenum into a first duct and a second duct, the first duct in communication with the first air passageway and the second duct in communication with the second air passageway,wherein the airflow divider includes a first wall member and a second wall member, wherein the first wall member and the second wall member operably separate the first duct from the second duct, andwherein the first wall member and the second wall member are orthogonal to the top wall, and further wherein an angular separation α of the first wall member from the second wall member ranges from about 45° to about 180°, wherein an increase in α decreases the proportion of air between the first portion and the second portion of the airflow. 2. The fan plenum of claim 1, wherein the airflow divider is positionally adjustable. 3. The fan plenum of claim 1, wherein the side wall includes a bottom edge, and wherein the plenum base is removably secured to the side wall and is adjustable relative to the bottom edge. 4. The fan plenum of claim 1, wherein the angular separation α of the first wall member from the second wall member is about 90°. 5. The fan plenum of claim 1, wherein the fan plenum is further configured to receive either an axial fan or a centrifugal fan. 6. A fan plenum for a refrigerated merchandiser, the refrigerated merchandiser including a case defining a product display area and including a lower flue, a first air passageway, and a second air passageway, the first air passageway and second air passageway in fluid communication with the lower flue and with the product display area, the fan plenum comprising: a top wall including a fan aperture for receiving a fan having a plurality of fan blades;a side wall;a plenum base; andan airflow divider that partitions the fan plenum into a first duct and a second duct, the first duct fluidly couplable with the first air passageway and the second duct fluidly couplable with the second air passageway,wherein the airflow divider is positioned between the top wall and the plenum base,wherein the airflow divider includes a first wall member and a second wall member,wherein the first wall member and the second wall member operably separate the first duct from the second duct, andwherein the second duct is partially defined between the first wall member and the second wall member. 7. The fan plenum of claim 6, wherein the airflow divider and the plurality of fan blades define a clearance therebetween of 3 millimeters and 25 millimeters. 8. The fan plenum of claim 6, wherein the airflow divider includes a first wall member and a second wall member, wherein the first wall member and the second wall member operably separate the first duct from the second duct, and further wherein an angular separation α of the first wall member from the second wall member ranges from about 45° to about 180°, whereby the quantity of air discharged to the first air passageway with respect to the second air passageway is proportional to α. 9. The fan plenum of claim 8, wherein the angular separation of the first wall member from the second wall member is about 90°. 10. The fan plenum of claim 6, wherein the side wall includes a bottom edge, and wherein the airflow divider is removably secured to the side wall and is adjustable relative to the bottom edge, whereby the quantity of air discharged to the first air passageway with respect to the second air passageway is proportional to a position of the airflow divider. 11. The fan plenum of claim 6, wherein the airflow divider is parallel to and spaced from the top wall. 12. The fan plenum of claim 6, wherein the airflow divider is positionally adjustable. 13. The fan plenum of claim 6, wherein the fan plenum is further configured to receive either an axial fan or a centrifugal fan. 14. A fan plenum for a refrigerated merchandiser, the fan plenum comprising: a top wall;a side wall;a plenum base; andan airflow divider having a first wall member and a second wall member that operably separate the fan plenum into a first duct configured for communication with a first air passageway of the refrigerated merchandiser and a second duct configured for communication with a second air passageway of the refrigerated merchandiser, wherein the first wall member and the second wall member are orthogonal to the top wall, and further wherein an angular separation α of the first wall member from the second wall member ranges from about 45° to about 180°,the air flow divider configured to direct a first portion of the airflow to the first air passageway and to direct a second portion of the airflow to the second air passageway, wherein a change in α changes a proportion of air between the first portion and the second portion of the airflow. 15. The fan plenum of claim 14, wherein the side wall includes a bottom edge, and further wherein the plenum base is removably secured to the side wall and is adjustable relative to the bottom edge. 16. The fan plenum of claim 14, wherein the plenum base is positioned parallel to the top wall. 17. The fan plenum of claim 14, wherein the airflow divider is positionally adjustable. 18. The fan plenum of claim 14, wherein the angular separation of the first wall member from the second wall member is about 90°. 19. The fan plenum of claim 14, wherein the fan plenum is further configured to receive either an axial fan or a centrifugal fan. 20. A fan plenum for a refrigerated merchandiser, the refrigerated merchandiser including a case defining a product display area and including a lower flue, a first air passageway, and a second air passageway, the first air passageway and second air passageway in fluid communication with the lower flue and with the product display area, the fan plenum comprising: a top wall including a fan aperture for receiving a fan having a plurality of fan blades;a side wall;a plenum base; andan airflow divider that partitions the fan plenum into a first duct and a second duct, the first duct fluidly couplable with the first air passageway and the second duct fluidly couplable with the second air passageway,wherein the airflow divider is positioned between the top wall and the plenum base,wherein the side wall includes a bottom edge, andwherein the airflow divider is removably secured to the side wall and is adjustable relative to the bottom edge, whereby the quantity of air discharged to the first air passageway with respect to the second air passageway is proportional to a position of the airflow divider.
