🔍 Key Concepts

• Locate the section of the system where liquid refrigerant flows after leaving the condenser and receiver, moving toward the expansion device and evaporator. • Identify the symbol for a filter‑drier, which both filters and removes moisture from the liquid line (often shown as a small cylinder in the liquid line). • Compare the labeled components B, C, D, and E with typical refrigeration components: condenser, receiver, filter‑drier, and king valve or service valve.

💭 Think About

• Follow the refrigerant path from the condenser outlet through the receiver and toward the evaporator. Which labeled component is placed in the liquid line specifically to protect the rest of the system from moisture and debris? • Look closely at the small cylinder‑shaped symbol in the liquid line below the receiver: which letter is directly attached to that symbol, rather than to valves or the larger tanks? • Which labeled choice corresponds to a device that is neither a heat exchanger (like a condenser) nor a large storage vessel (like a receiver), but a smaller inline treatment device?

✅ Before You Answer

• Verify that the component you pick is downstream of the condenser/receiver and upstream of the expansion and evaporator on the high‑pressure liquid line. • Confirm that the symbol for your chosen letter is a small inline cylinder rather than a large shell‑and‑tube or vertical tank symbol. • Double‑check that other options (B, C, E) represent different functions (such as condenser, receiver, or valve station) and are not primarily for moisture removal.
