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, Kafe, Webinar 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.

A refrigerated display case with an improved air flow control system located in the lower portion thereof along with an improved means for controlling spillages and other contaminants which commonly fall downwardly into the tank or lower area thereof. The spillage controls including a waste control outlet along with an inclined coil cover and fan housing as well as a deck plate extending thereover. The deck plate also defining the plenum chamber within which the inclined fan housing and inclined coil and coil cover are located. A front bracket is include...

A refrigerated display case apparatus with an improved air flow control and a contaminant control apparatus and having a frontal opening with a refrigerated air curtain extending thereover comprising: A. an upper air conduit means extending upwardly along a refrigerated display case to define an upper air flow path therein for conveying refrigerated air therethrough, said upper air conduit means defining an air outlet means therein above the frontal opening of the refrigerated display case for releasing refrigerated air therefrom to form a refrigerated air curtain extending thereover, said air outlet means being in fluid flow communication with respect to said upper air conduit means; B. a lower air conduit means extending upwardly within said refrigerated display case to define a lower air flow path and an air inlet means below the frontal opening to receive air therein from the refrigerated air curtain extending over the frontal opening of the refrigerated display case, said air inlet means being in fluid flow communication with respect to said lower air flow path; C. a plenum housing attached with respect to said upper air conduit means and said lower air conduit means, said plenum housing defining a plenum chamber means therein in fluid flow communication with respect to said lower air flow path of said lower air conduit means to receive air therefrom returning through said air inlet means from the refrigerated air curtain, said plenum chamber means also being in fluid flow communication with respect to said upper air flow path of said upper air conduit means to supply refrigerated air thereto for exiting through said air outlet means, said plenum housing including; (1) a plenum outer liner means extending from said lower air conduit means to said upper air conduit means to define an outer wall means of said plenum chamber means, said plenum outer liner means including a waste receiving means therein adapted to gather contaminants from within the refrigerated display case, said plenum outer liner means further defining a recessed waste gathering area surrounding said waste receiving means to facilitate movement of contaminants thereto, said waste receiving means defining a waste outlet means for effecting removal of contaminants from the refrigerated display case; (2) a deck plate means detachably positioned attached with respect to and extending from said lower air conduit means, said deck plate means also being detachably in abutment with respect to said upper air conduit means and extending outwardly over said plenum chamber means to said lower air conduit means to define an inner wall means of said plenum chamber means, said inner wall means and said outer wall means defining said plenum chamber means therebetween, said deck plate means being inclined downwardly at an angle of approximately seven degrees toward said waste receiving means to facilitate movement of contaminants therein; (3) a rear panel means fixedly secured to said upper air conduit and extending outwardly therefrom to receive said deck plate means in abutment therewith to facilitate attachment of said deck plate means detachably with respect to said coil housing means; D. an air flow control apparatus positioned within said plenum chamber means and comprising: (1) a coil housing means including a refrigeration coil means mounted therein, said coil housing means be positioned within said plenum chamber means for cooling of air therein; (2) a coil cover means positionable extending outwardly over said refrigeration coil means for protection thereof, said coil cover means being inclined downwardly at an angle of approximately two degrees toward said waste receiving means at an angle of greater than two degrees to facilitate movement of any contaminants therein, said coil cover means being pivotally attached with respect to said coil housing means to facilitate selective access to said refrigeration coil means, said coil cover means including a coil cover gasket means positioned between said coil cover means and said coil housing means to inhibit movement of contaminants into said refrigeration coil means; (3) a fan panel means positioned within said plenum chamber means pivotally mounted adjacent said coil housing means for moving air therethrough for refrigeration thereof, said fan panel means defining at least one fan opening means therein, said fan panel means being pivotally mounted with respect to said coil housing means to facilitate further access thereto, said fan panel means being inclined downwardly toward said waste receiving means to facilitate movement of contaminants therein, said coil cover means extending over said fan panel means to inhibit movement of contaminants therebetween into said refrigeration coil means; (4) fan hinge means secured to said fan panel means and to said coil housing means to achieve pivotally moveable securement therebetween; (5) a fan basket housing means positionable within each of said fan opening means and including a flange means extending therearound to inhibit movement of contaminants through said fan opening means into said refrigeration coil means; (6) at least one fan means positioned within each of said fan basket housing means within said fan opening means of said fan panel means, said fan means adapted to draw air from said lower air conduit means into said plenum chamber means for passing through said refrigeration coil means for cooling thereof and into said upper air conduit means for supplying of refrigerated air to exit through said air outlet means to form a refrigerated air curtain over the frontal opening of the refrigerated display case; (7) refrigeration line means positioned within said plenum chamber means adjacent said waste receiving means; E. a front bracket means fixedly secured to said lower air conduit means adjacent said air inlet means, said front bracket means including a support shelf means adapted to receive said refrigeration line means positioned thereon to facilitate movement of contaminants toward said waste receiving means and cleaning therearound; F. a return grill means detachably securable onto said front bracket means to extend over said air inlet means, said return grill means including a deck lip means extending outwardly therefrom and adapted to receive said deck plate means positioned thereon in detachable abutment with said front bracket means for positioning of said deck plate means detachably with respect to said lower air conduit means; and G. a front baffle means fixedly secured to said front bracket means for securement thereof with respect to the refrigerated display case.
