Wall-mounted refrigerator and peltier effect cooling system

A wall-mounted refrigerator comprising:

• a frame having an insulated compartment comprising a plurality of shelves;
• a front panel covering said frame and having at least one window for displaying refrigerated articles supported by said shelves;
• at least one door to access said articles supported by said shelves;
• a cooling unit;
• an air recirculation system having a warm air collector for collecting warm air and having a warm air channel for directing air through said cooling unit to provide cooled air, at least one fan, and a cold air channel for directing said cooled air back into said compartment;
• a mounting for anchoring said refrigerator with respect to a wall;
• and
• wherein a thermal efficiency of said refrigerator is enhanced by at least one of:
• said shelves comprising staggered shelves having a bottle-support surface for supporting sides of horizontally disposed bottles, said shelves extending partly across said compartment leaving a central portion of said compartment free of any shelves so that in use necks of bottles can be nested within said compartment, said warm air collector being located at a central top portion of said compartment and said cold air channel comprising two channels located at the vertical lateral sides of said compartment, said two channels having openings for directing cold air inwardly towards said shelves for cooling bottles on said shelves;
• said at least one door being mounted at a side of said compartment to access said shelves from a side, said door incorporating an air channel;
• said window comprising at least two panes having an outer pane forming said front panel beyond said window;
• and
• said cooling unit comprising a thermoelectric cooling unit arranged above said compartment within said frame and having a lower cold air heat exchanger and an upper hot air heat exchanger discharging heated air above said refrigerator, said warm air collector being located at a top of said compartment in direct communication with said lower cold air heat exchanger.
