🔍 Key Concepts

• Follow the refrigerant flow from the compressor discharge through the high‑pressure (red) side of the system • Identify where the hot high‑pressure vapor is cooled and condensed to liquid before entering the receiver • Know the visual difference between the condenser coil and the evaporator coil in schematic diagrams

💭 Think About

• Starting at component 11 (compressor), trace the red discharge line: which numbered component is the first long coil the refrigerant enters after leaving the compressor? • Which numbered component is located upstream of the receiver (the red tank) and downstream of the compressor on the high‑pressure side? • Compare the coil on the right (red) and the coil on the left (blue): which one would logically be rejecting heat to the surroundings rather than absorbing it?

✅ Before You Answer

• Verify which side of the system is the high‑pressure, hot discharge side (red) versus the low‑pressure, cold side (blue) • Confirm that the condenser must be before the receiver and expansion valve in the flow direction • Make sure you are not confusing the evaporator coil (in the cold box on the left) with the condenser coil (on the hot side)
