Which statement correctly describes the relationship between condenser and evaporator?

• A. The evaporator performs the opposite function of the condenser
• B. The condenser increases pressure of refrigerant
• C. The condenser performs the opposite function of the evaporator
• D. The condenser and evaporator are interchangeable

Answer: (C)

In a refrigeration cycle, the condenser and evaporator have opposite roles in heat transfer and phase change. The condenser rejects heat to the surroundings and changes high-pressure refrigerant vapor into a liquid, while the evaporator absorbs heat from the refrigerated space and turns liquid refrigerant into vapor at low pressure. Because of this opposite-function relationship, describing the condenser as performing the opposite function of the evaporator correctly captures their distinct, complementary roles. The condenser isn’t about increasing pressure itself—that’s the job of the compressor—and the two components aren’t interchangeable, since each performs a different part of the cycle.
