- ✓ Compressor, condenser, metering device, and evaporatorCorrect
- B. Compressor, receiver, filter-drier, and evaporator
- C. Condenser, receiver, expansion valve, and cooling coil
- D. Compressor, condenser, receiver, and cooling coil
Why A is correct
NAVEDTRA 14075 §6-1 identifies the four essential components of the vapor-compression cycle as the compressor, condenser, metering (expansion) device, and evaporator, connected in a loop. The receiver and filter-drier are ancillary components, not part of the four-component cycle definition.
