Multiple Choice

In an orifice-tube A/C system, where is the compressor located?

Compressors in vapor‑compression systems must receive only vapor, not liquid. The accumulator sits on the low‑pressure suction line and collects any liquid that might return from the evaporator, preventing liquid slugging and protecting the compressor. From the accumulator, refrigerant gas is drawn into the compressor, then discharged to the condenser. After compression, the high‑pressure gas goes to the condenser and then to the metering device and evaporator, completing the cycle. In an orifice‑tube setup, this arrangement places the compressor after the accumulator and before the condenser, which is why this location is correct.
