Refrigerated merchandiser with foul-resistant condenser
View Patent ↗A refrigerated cold beverage merchandiser ( 10 ) includes an enclosure defining an insulated, refrigerated display cabinet ( 25 ) and a compartment ( 30 ) heat insulated therefrom wherein a compressor ( 40 ) a condenser ( 50 ) and a condenser fan ( 60 ) are disposed. The condenser ( 30 ) is formed by a plurality of in-line tube banks ( 52 ). Each tube bank ( 52 ) is a serpentine tube formed a plurality of parallel straight tube segments ( 54 ) extending in horizontal rows ( 55 ) between a pair of spaced, opposed end plates ( 58 ) and elbow turns ( 56 ) connecting neighboring straight tube segments ( 56 ) in a conventional manner. Each successive tube bank ( 52 ) is aligned with the other tube banks so that respective parallel tube rows ( 55 ) are disposed in-line from the front to the rear of the condenser ( 50 ).
1. A refrigerated merchandiser comprising:
an enclosure having a rear wall, a bottom wall, a top wall, a pair of side walls and a front wall defining a refrigerated display cabinet and having an access opening in said front wall for providing access to the refrigerated display cabinet;
an evaporator disposed in operative association with the refrigerated display cabinet;
a compartment heat insulated from the refrigerated display cabinet;
a condenser mounted to a base plate disposed within said compartment, said condenser having a plurality of non-finned tube banks, each tube bank having a plurality of parallel, straight non-finned tube rows extending between a pair of spaced end plates, the tube banks being disposed such that respective tube rows are aligned in an in-line arrangement;
a condenser fan mounted to the base plate disposed within said compartment in operative association with said condenser, said condenser fan disposed downstream with respect to airflow of said condenser so as to draw airflow through the non-finned tube banks of said condenser;
a compressor mounted to the base plate disposed within said compartment and connected in refrigerant flow communication with said evaporator and said condenser for circulating refrigerant through said evaporator and said condenser; and
a top plate extending between the condenser end plates over said plurality of condenser tube banks, and a shroud encompassing said condenser fan and mating with the condenser end plates and top plate thereby forming with the base plate tunnel about said condenser and said condenser fan.
2. A refrigerated merchandiser as recited in claim 1 wherein the base plate is slidably removable from the compartment with said compressor, said condenser and said condenser fan.
