What happens to the refrigerant in the condenser?
Refrigeration · EPA 608 Core. The correct answer, and the reasoning behind it.
The refrigeration cycle, refrigerant states and pressures, gauges and leak detection.
The question
What happens to the refrigerant in the condenser?
- It boils and absorbs heat from the room air
- It gives up heat and condenses to a liquidCorrect answer
- Its pressure drops sharply
- It is filtered of moisture and acid
Why “It gives up heat and condenses to a liquid” is correct
Hot, high-pressure vapor from the compressor gives up heat in the condenser and condenses into high-pressure liquid. The liquid then travels to the metering device.

Why the other answers are wrong
- It boils and absorbs heat from the room air — Boiling and absorbing heat happen in the evaporator.
- Its pressure drops sharply — The large pressure drop happens at the metering device.
- It is filtered of moisture and acid — Filtering is the job of a filter-drier, not the condenser.
