🔍 Key Concepts

• Latent heat vs. sensible heat in phase changes (liquid ↔ vapor) • What physically happens to refrigerant inside the condenser of a refrigeration plant • Where compression happens in the cycle and what type of heat is associated with it

💭 Think About

• When refrigerant is in the condenser, is it mainly changing temperature, changing state, or both? What type of heat is tied to a change of state? • Which component of the system actually performs compression, and would its heat be removed in the condenser or created in the compressor? • If you understand what happens in each component (compressor, condenser, expansion device, evaporator), which one is associated with condensation and removal of heat to the cooling medium (air or water)?

✅ Before You Answer

• Be clear on the definition of latent heat (heat added/removed with no temperature change during phase change). • Be clear on the definition of sensible heat (heat that causes a temperature change you can measure). • Match each answer choice to the specific component of the refrigeration cycle where that process actually occurs (expansion valve, compressor, condenser, evaporator).
