🔍 Key Concepts

• Effect of pressure drops in liquid refrigerant lines on saturation temperature and boiling point • Relationship between liquid line pressure and the formation of vapor (flash) before the metering device • Normal causes and symptoms of compressor hunting and expansion valve freezing

💭 Think About

• Think about what happens to a saturated liquid refrigerant when its pressure is reduced while temperature stays about the same—does it stay fully liquid or start changing state? • Which of these options directly involves a change of state of the refrigerant in the liquid line, rather than a mechanical failure of a component? • In a properly operating system, where should most of the refrigerant boiling/expansion occur, and what problem arises if this starts happening earlier in the liquid line?

✅ Before You Answer

• Verify which choice involves refrigerant behavior (phase change) rather than a component malfunction as the primary effect of a pressure drop. • Check your HVAC/refrigeration fundamentals: a drop in pressure at constant temperature tends to cause a portion of liquid refrigerant to vaporize—what is this called? • Confirm which option would most directly reduce the amount of pure liquid reaching the expansion (metering) device, leading to poor system performance.
