🔍 Key Concepts

• Basic refrigeration cycle: evaporator, compressor, condenser, expansion device • Where the pressure drop occurs vs. where the heat absorption/rejection occurs • Relationship between pressure drop and temperature drop in a refrigerant

💭 Think About

• In the ideal refrigeration cycle, which component is designed specifically to reduce the refrigerant pressure suddenly? • When the refrigerant’s pressure drops sharply, what happens to its temperature, and in which component is this intentional and controlled? • Compare the functions of the evaporator, compressor, expansion valve, and receiver: which one mainly changes phase/pressure to set up cooling, and which one mainly absorbs heat from the box?

✅ Before You Answer

• Identify which component is the metering/expansion device in the list of choices • Recall that the largest instantaneous temperature drop is tied to the largest controlled pressure drop • Verify which components mainly act as storage or heat exchangers, and which one is the pressure-reducing device
