🔍 Key Concepts

• Properties of refrigerants in vapor-compression systems • Relationship between boiling point and ability to absorb heat at low temperatures • Why specific heat and freezing point matter in closed refrigeration cycles

💭 Think About

• Think about what has to happen to the refrigerant in the evaporator: should it boil (vaporize) easily at low temperatures, or only at very high temperatures? • In a freezer, the refrigerant must remain fluid and change state where temperatures are well below 0°C. Which property helps make that possible? • Which property helps the refrigerant absorb a lot of heat during a phase change at a relatively constant temperature?

✅ Before You Answer

• Compare boiling point vs. required evaporation temperature in the evaporator coil • Consider whether a high freezing point would risk the refrigerant turning solid in low-temperature parts of the system • Think about whether specific heat or latent heat of vaporization is the key factor in refrigeration performance
