Refrigeration Unit parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.
#PartQtyWhat it does
1 Compressor 4 parts 1× Belt or motor-driven compressor raising refrigerant pressure around the loop.
2 Condenser Coil 1× Finned coil rejecting heat to ambient air at the front of the unit.
3 Evaporator Coil 1× Finned coil inside the box absorbing heat as refrigerant boils.
4 Refrigerant Charge 1× Working-fluid charge (e.g. R-452A) circulating through the loop.
5 Evaporator Blower 3 parts 1× Evaporator fan
6 Reefer Controller 3 parts 1× Microcontroller board regulating set-point temperature, defrost, and alarms.
