🔍 Key Concepts

• Latent heat of vaporization in a refrigeration cycle • Roles of compressor, condenser, receiver, evaporator in the cycle • Where the refrigerant changes from liquid to vapor and absorbs heat

💭 Think About

• In which component is the refrigerant a low‑pressure, cold liquid that is ready to pick up heat? • Where in the system does the refrigerant boil/evaporate by taking heat from the space or substance being cooled? • Which component’s main job is to reject heat to the outside, and which one’s job is to absorb heat from the cooled space?

✅ Before You Answer

• Identify the component where the phase change from liquid to gas (boiling) happens at low pressure. • Confirm which component is on the high‑pressure side and which is on the low‑pressure side of the system. • Verify which component is specifically designed as the cooling surface inside the box/space being refrigerated.
