🔍 Key Concepts

• Locate the evaporators in the system and follow their outlet (suction) lines back toward the compressor. • Review what an evaporator pressure regulator (EPR) does: it is installed in the suction line and is designed to maintain a minimum pressure/temperature in the evaporator. • Compare the symbols for the different valves: thermostatic expansion valve (TXV) on the liquid line vs. pressure‑regulating valve on the suction line.

💭 Think About

• Starting at each evaporator outlet, which numbered component is the first control device you pass before the suction line rejoins the main suction header? • Which of the numbered items is located on the low‑pressure (suction) side rather than on the high‑pressure/liquid side of the system? • Looking at the valve symbols, which one shows a pressure‑regulating function on the suction line rather than simple shutoff or solenoid operation?

✅ Before You Answer

• Verify which components are on the suction line returning to the compressor, not on the high‑pressure discharge or liquid line. • Confirm that the chosen number is downstream of an evaporator and upstream of the compressor in the suction path. • Make sure you are not confusing the TXV or solenoid valve on the liquid line with the evaporator pressure regulator on the suction line.
