housing 23 a compactor off start switch 25 and refrigeration switch 27 are also provide in one embodiment the refrigeration switch 27 includes off u201c low u201d u201c medium u201d and u201c high u201d settings from fig2 it can be seen that a refrigeration apparatus 28 is attached to a rear panel 29 of the housing 23 the refrigeration apparatus 28 includes a compressor 31 and serpentine heat exchange piping 33 the heat exchange piping 33 is attached to a grate 35 comprising a plurality of parallel bars which are attached to the rear panel 29 the rear panel 29 and side panels e g 34 are interconnected metal panels for example such as steel or aluminum and thus are cooled by the grate when the refrigeration unit is in operation the refrigeration unit 28 may operate according to a conventional vapor compression cycle in this cycle a circulating refrigerant such as r134a enters the compressor 31 as low pressure vapor at or slightly above the temperature of the refrigerator interior the vapor is compressed and exits the compressor 31 as high pressure superheated vapor the superheated vapor travels under pressure through coils or tubes 33 comprising a condenser which is passively cooled by exposure to air in the room the condenser cools the vapor which liquefies as the refrigerant leaves the condenser it is still under pressure but is now only slightly above room temperature this liquid.
