Modular refrigeration unit and refrigerator

A refrigerator comprising:

• a refrigeration cabinet comprising insulated outer walls and at least one access door for accessing an insulated main chamber of the cabinet;
• the refrigeration cabinet comprising a condenser chamber extending inwardly from an aperture in an outer wall of the cabinet, the condenser chamber being at least partially defined by at least one insulated interior wall portion with at least one mating surface thereon, said at least one mating surface being positioned distal to the aperture, said at least one mating surface defining an opening between the condenser chamber and the main chamber;
• a modular refrigeration unit for installation in the cabinet, the modular refrigeration unit comprising:
• a condenser assembly;
• an evaporator assembly;
• a bulkhead assembly positioned between the condenser assembly and the evaporator assembly, the bulkhead assembly having a periphery receivable in said opening between the condenser chamber and the main chamber;
• a gasket assembly coupled to one of said bulkhead periphery and said at least one mating surface;
• the gasket assembly comprising a thermal breaker portion mounted onto one of said bulkhead periphery and said at least one mating surface and a vane mounted on the thermal breaker portion and engageable with the other of said bulkhead periphery and said at least one mating surface when the bulkhead assembly is located in said opening;
• and
• the modular refrigeration unit being adapted for movement substantially transverse to the bulkhead assembly for engaging the vane with the other of said bulkhead periphery and said at least one mating surface to form a substantially air-tight seal between the condenser chamber and the main chamber.
