🔍 Key Concepts

• Pump-down cycle operation in an automatic refrigeration system • Role of the liquid line solenoid valve in a pump-down cycle • How a low-pressure control starts and stops the compressor based on suction pressure

💭 Think About

• In a pump-down cycle, what happens to the refrigerant when the solenoid valve is energized versus when it is de-energized? • How does suction pressure change right before the compressor stops and right before it starts again? • Which control (pressure or temperature) is actually making the decision to restart the compressor in a pump-down system?

✅ Before You Answer

• Identify which component directly affects suction pressure in normal operation of a pump-down system • Recall whether a compressor in a pump-down system starts on falling suction pressure or on rising suction pressure • Confirm which option describes the condition that the low-pressure control is set to react to for a restart
