         9 . Refrigerated sales cabinet ( 2 ) according to  claim 1 ,
 wherein the refrigerated sales cabinet ( 2 ) is formed as a semi plug-in cabinet ( 2 );   wherein the vapor compression cycle comprises at least one compressor ( 16 ), at least one condenser ( 20 ), an expansion device and an evaporator ( 30 ) and refrigerant conduits interconnecting these elements and circulating a refrigerant therethrough; and   wherein the at least one condenser ( 20 ) is formed as a heat exchanger transferring heat from the compressed hot refrigerant to a brine.   
     
     
         10 . Refrigerated sales cabinet ( 2 ) according to  claim 1 ,
 wherein the refrigerated sales cabinet ( 2 ) is formed as a plug-in cabinet;   wherein the vapor compression cycle comprises at least one compressor ( 16 ), at least one condenser ( 20 ), an expansion device and an evaporator ( 30 ) and refrigerant conduits interconnecting these elements and circulating a refrigerant therethrough; and   wherein the at least one condenser ( 20 ) is formed as a heat exchanger transferring heat from the compressed hot refrigerant to ambient air.   
     
     
         11 . Refrigerated sales cabinet ( 2 ) according to  claim 9 ,
 wherein the at least one condenser ( 20 ) is arranged at or on top of a roof portion of the cabinet body ( 4 );   wherein the vapor compression cycle further comprises a pressure line ( 18 ) extending between the at least one compressor ( 16 ) and the at least one condenser ( 20 ); and   wherein the pressure line ( 18 ) extends behind the rear wall ( 12 ) of the cabinet body ( 4 ) and is covered, at least partially, by a ledge ( 34 ), particularly a U-shaped ledge ( 34 ), mounted on the rear face of the real wall ( 12 ) of the refrigerated sales cabinet ( 2 ), seen from behind.
