🔍 Key Concepts

• Function and location of a refrigeration accumulator in a vapor-compression system • Difference in purpose between a liquid receiver and a suction accumulator • How the suction line is routed between the evaporators and the compressor

💭 Think About

• Trace the blue (low-pressure/suction) line from the evaporators back to the compressor and note which numbered component is installed in that line just before the compressor inlet. • Compare the shapes and positions of items 3, 17, and 18 and decide which one is protecting the compressor from liquid refrigerant carryover rather than simply storing liquid. • Ask yourself which component would normally be on the high‑pressure liquid side versus on the low‑pressure suction side in a standard refrigeration schematic.

✅ Before You Answer

• Confirm which color/line in the diagram represents the suction (low‑pressure, cool) vapor returning to the compressor. • Verify that an accumulator is installed in the suction line immediately ahead of the compressor inlet and is usually a vertical vessel intended to keep liquid out of the compressor. • Double‑check that the component you choose is not on the high‑pressure liquid line going from the condenser/receiver toward the expansion devices.
