🔍 Key Concepts

• Role of a liquid line in a refrigeration system (where it is located in the flow path) • What component is most sensitive to small particles, dirt, and scale and has small internal passages/orifices • Normal flow sequence: condenser → receiver → liquid line → strainer → ?

💭 Think About

• Trace the refrigerant flow from the condenser outlet, through the receiver, and along the liquid line. Which component comes next? • Ask yourself: Which of the listed components would be most easily plugged or affected by very small bits of dirt or scale? • Consider which component relies on a precisely controlled flow of liquid refrigerant through a very small opening.

✅ Before You Answer

• Verify where the liquid line strainer is physically installed in a standard refrigeration piping diagram. • Identify which option corresponds to a component that has a small metering/orifice passage that can be blocked by debris. • Eliminate choices that are located upstream of the liquid line strainer in the flow path (they would not be protected by it).
