An appliance cabinet includes a wrapper that has sidewalls and define a machine compartment. An attachment feature is coupled to the wrapper proximate the sidewalls. The attachment feature includes horizontal supports and vertical supports that define a lattice structure of the attachment feature, and a selectively removable side access panel is removably coupled to the sidewalls to define at least one access point to the machine compartment.

A refrigerator includes a noise reduction device and a machine room that accommodates a condenser and a compressor. The noise reduction device includes a sensing unit configured to measure noise generated from the machine room of the refrigerator and a generating unit configured to output a sound signal having a frequency canceling or reducing the noise. The machine room is defined by a case that has a communication portion configured to communicate a fluid between an inside of the case and an outside of the case to thereby exchange heat between the fluid and the condenser and between the fluid and the compressor.

A refrigerating appliance includes a refrigerating cabinet that has an outer wrapper. A machine compartment is disposed proximate a rear bottom of the refrigerating cabinet. The machine compartment is defined by selectively removable side panels, an inner curved surface of the outer wrapper, and a bottom support plate. A controller is disposed within the machine compartment. Reinforcement segments extend from a planar extent of the outer wrapper to a lip of the bottom support plate.

A refrigerator includes a body, first and second storage compartments and a machine compartment formed in the body, a blower fan disposed in the machine compartment, first and second refrigerating units comprising first and second compressors to compress first and second refrigerants, respectively, first and second condensers to condense the first and second refrigerants, respectively, first and second expansion valves to expand the first and second refrigerants, respectively, and first and second evaporators to evaporate the first and second refrigerants, respectively, the first and second refrigerating units supplying cold air to the first and storage compartments, respectively. The first compressor, the second compressor, and the first condenser are disposed in the machine compartment and are cooled by forcible flow of air caused by the blower fan, and the second condenser is disposed outside the machine compartment and is cooled by natural convection of air.

An appliance cabinet includes first and second sidewalls. A rear wall is disposed between the first and second sidewalls. A machine compartment is defined by a lower portion of the rear wall. An attachment feature defines openings and is coupled to at least one of the first and second sidewalls. A side access panel is selectively coupled to at least one of the first and second sidewalls via fasteners extending through the openings defined by the attachment feature.
