🔍 Key Concepts

• Follow the flow of refrigerant from the compressor discharge to the expansion valves and evaporators • Distinguish between a condenser (rejects heat from refrigerant) and an evaporator (absorbs heat into refrigerant) • Notice where cooling water (labeled W) is used in the system and what component it passes through

💭 Think About

• On this diagram, after the refrigerant leaves the compressor (A), which labeled component does it enter where its temperature should drop and it changes from vapor toward liquid? • Which component is in contact with cooling water W, and what does that tell you about its job in the cycle? • Look at components J and K: do they give heat to the refrigerant or take heat away from the refrigerant?

✅ Before You Answer

• Identify which labeled item is the condenser (rejects heat from refrigerant to cooling water) • Confirm that the chosen component is on the high‑pressure side between the compressor discharge and the receiver C • Make sure you are not choosing an evaporator (where the refrigerant gains heat from the refrigerated space)
