Question 1 of 27070

A pressure drop in the liquid line of a refrigeration system may cause what condition?

🔍 Key Concepts

• Basic refrigeration cycle: compressor, condenser, receiver, expansion valve, evaporator • Difference between liquid refrigerant and flash gas in the liquid line • Effect of pressure drop on refrigerant temperature and boiling/flash point

💭 Think About

• Think about what happens to a saturated liquid refrigerant when its pressure suddenly drops while its temperature stays the same. • Which component or condition in the system is most sensitive to pressure changes in the liquid line itself, before the expansion valve? • Of the four choices, which one directly involves refrigerant state change (liquid to mixture of liquid and vapor) rather than mechanical failure of a part?

✅ Before You Answer

• Review that lower pressure lowers the saturation/boiling temperature of the refrigerant. • Ask yourself: if the pressure drops but the refrigerant is still warm for that new pressure, does it tend to stay liquid or start boiling? • Identify which option describes a change of phase in the liquid line, not damage or malfunction of a valve or compressor.
