🔍 Key Concepts

• Function and location of the receiver in a refrigeration system (usually on the high-pressure/liquid side) • Difference between handling liquid refrigerant vs vapor refrigerant in the system • What happens during a pump down and where refrigerant is normally stored

💭 Think About

• Ask yourself: Is the receiver designed mainly for liquid or vapor, and is it on the high or low pressure side of the system? • Which option best matches a storage/holding role for refrigerant in normal or pump‑down operation, rather than a control or protective function? • Which of the other choices describe functions that are normally done by different components (like accumulators, condensers, or separators)?

✅ Before You Answer

• Verify which component in a refrigeration system normally stores liquid refrigerant on the high‑pressure side • Identify which component is used to collect air and non‑condensables (hint: that’s usually not the receiver) • Confirm which component prevents liquid refrigerant from reaching the compressor, and whether that’s located on the suction (low‑pressure) side or liquid (high‑pressure) side
