🔍 Key Concepts

• Relationship between liquid line condition and TXV (thermostatic expansion valve) operation • What bubbles in a liquid refrigerant line indicate about pressure and phase of the refrigerant • Effects of two‑phase flow (liquid + vapor) on system components

💭 Think About

• If the liquid line has bubbles, is the refrigerant still a solid column of liquid when it reaches the expansion valve? How might that affect valve internals over time? • Would bubbles in the liquid line increase or decrease condensing pressure, and why? Think about what mainly controls condensing pressure. • Can bubbles simply "disappear" in the receiver, or do they indicate a problem somewhere else in the system (charge, subcooling, restrictions)?

✅ Before You Answer

• Clarify what the receiver does: does it "absorb" bubbles, or just store liquid refrigerant? • Recall what condition is required at the inlet of a TXV (solid column of liquid vs mixture of liquid and vapor). • Think about which option describes a mechanical damage or wear effect that could logically result from flashing/bubbles passing through a small orifice.
