Patent ID: 8826686

Claim:
A refrigeration apparatus comprising: a refrigerant circuit including a compressor, an evaporator, a heat exchanger, a first pipe connected between the compressor and the heat exchanger, and a second pipe connected between the evaporator and the heat exchanger; a mechanical chamber including the compressor; an insulating box including a storage chamber surrounded by the evaporator and an accommodating room arranged between the mechanical chamber and the storage chamber; and an insulating structure including an insulating material surrounding the heat exchanger; wherein the insulating structure is detachably accommodated in the accommodating room, the insulating structure including at least a first planar surface and a second planar surface opposite to the first planar surface, the insulating structure being inserted into an opening of the accommodating room from a side of the first planar surface, wherein the first pipe and the second pipe extend from the second side of the insulating structure, wherein the insulating structure has at least one major planar surface and at least two minor planar surfaces, the at least two minor planar surfaces including the first and second planar surfaces, wherein the at least one major planar surface is parallel to a wall between the storage chamber and the mechanical chamber, wherein the at least two minor planar surfaces are not parallel to the wall between the storage chamber and the mechanical chamber.
