🔍 Key Concepts

• Latent heat of condensation vs sensible heat (temperature change without phase change) • Role of the condenser in a basic vapor‑compression refrigeration cycle • Where in the cycle the refrigerant actually changes state from vapor to liquid

💭 Think About

• In which part of the system does the refrigerant reject heat to the surroundings while changing from vapor to liquid? • Does an expansion valve remove heat, or does it mainly change pressure and cause some flashing/boiling? • What happens to refrigerant temperature and phase when it is on the suction side of the compressor?

✅ Before You Answer

• Be clear on which component is responsible for rejecting heat to the environment • Identify where the phase change (vapor to liquid) occurs in a standard refrigeration diagram • Eliminate any option that mostly affects pressure or flow control rather than directly removing latent heat
