USCG Exam PracticeRefrigeration principles and systems
In the vapor-compression refrigeration cycle, where does the refrigerant absorb heat from the space being cooled?
- A. Condenser
- B. Compressor
- ✓ EvaporatorCorrect
- D. Receiver
Why C is correct
The evaporator is where low-pressure liquid refrigerant boils and absorbs heat from the surrounding air, water, or brine, cooling the refrigerated space. The condenser rejects heat; the compressor raises pressure; the receiver stores liquid charge. (NAVEDTRA 14075 §6-1, §6-5)
