Aerothermodynamic separator for refrigerated display cabinet

Abstract

An aerothermodynamic separator for a refrigerated display cabinet is disclosed. The separator comprises a flat member having a predetermined dimension defining a shape of the separator. The separator is adapted to be removably positioned between a front end of one or more shelves associated with the cabinet and a rear end of a connecting region between two adjacent doors of the cabinet. The separator is adapted to restrict infiltration of outside air in a conservation space behind the doors of the cabinet upon opening at least one of the doors.

         7 . The separator of  claim 1 , wherein the cabinet is a semi-vertical refrigerated display cabinet with flat glass doors, wherein the separator comprises a front edge in contact with and extending along the connecting region between the two adjacent doors of the cabinet, a rear edge attached to the front end of each of the shelves, a top edge attached to a top inner wall of the cabinet, and a bottom edge attached to a bottom inner wall of the cabinet. 
     
     
         8 . The separator of  claim 1 , wherein the cabinet is a semi-vertical refrigerator display cabinet with curved glass doors, wherein the separator comprises a curved front edge that remains in contact with and extends along the connecting region between the two adjacent curved doors of the cabinet, a rear edge attached to the front end of each of the one or more shelves, a top edge attached to a top inner wall of the cabinet, and a bottom edge attached to a bottom inner wall of the cabinet. 
     
     
         9 . The separator of  claim 1 , wherein a flat surface of the separator is oriented substantially perpendicular to the closed doors of the cabinet and is extending vertically from top to bottom of the cabinet. 
     
     
         10 . A refrigerated display cabinet comprising:
 a case comprising one or more shelves extending between side walls of the case to form a conservation space to support and store one or more products therewithin;   two or more doors movably coupled to a front of the case and adapted to move between an open position and a closed position; and   at least one separator positioned between a front end of the one or more shelves and a rear end of a connecting region between two doors among the two or more doors,   wherein the separator restricts infiltration of outside air in the conservation space behind the closed doors of the cabinet upon opening at least one of the adjacent doors.   
     
     
         11 . The refrigerated display cabinet of  claim 10 , wherein the at least one separator is positioned behind the connecting region at a free end of one of the two doors, wherein the free end is used to open the door. 
     
     
         12 . The refrigerated display cabinet of  claim 10 , wherein the at least one separator is positioned behind the connecting point at a hinged end or pivot end of one of the two doors. 
     
     
         13 . The refrigerated display cabinet of  claim 10 , wherein the cabinet comprises a refrigeration system that is configured to maintain a predefined temperature in the conservation space of the cabinet. 
     
     
         14 . The refrigerated display cabinet of  claim 13 , wherein the refrigeration system is configured to create a recirculating air curtain in front of the one or more shelves or behind the doors of the cabinet, the air curtain is configured to create an aerothermodynamic barrier between the conservation space of the cabinet and environment. 
     
     
         15 . The refrigerated display cabinet of  claim 14 , wherein the refrigeration system comprises:
 a duct extending from a bottom front side of the cabinet to a top front side of the cabinet via a rear side of the cabinet;   a cooling unit configured within the duct and operable to cool the air flowing through the duct to the predefined temperature; and   a fan positioned adjacent to the cooling unit within the duct, the fan configured to facilitate inflow of air within the duct through the bottom front side of the cabinet, pass the received air through the cooling unit that cools the received air, and pump out the cool air from the top front side of the cabinet,   wherein the cool air pumped out by the top front side of the cabinet is received by the bottom front side of the cabinet such that the air curtain is formed in front of the one or more shelves or behind the doors of the cabinet.   
     
     
         16 . The refrigerated display cabinet of  claim 10 , wherein the top front side of the duct is configured with a discharge air grille (DAG) and the bottom front side of the duct is configured with a return air grille (RAG), wherein the DAG and the RAG control air directivity and facilitates the creation of the air curtain in front of the one or more shelves or behind the doors of the cabinet. 
     
     
         17 . The refrigerated display cabinet of  claim 10 , wherein the cabinet comprises a perforated wall panel (PWP) configured with the duct on the rear side of the cabinet, the PWP is configured to discharge a portion of the cool air, passing through the duct, in the conservation space to maintain the predefined temperature therewithin.
