USCG Exam PracticeRefrigeration principles and systems
In the vapor-compression refrigeration cycle, where does the refrigerant absorb heat from the space being cooled?
- A. Compressor
- B. Condenser
- ✓ 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 adds heat through compression; the receiver is a storage vessel. (NAVEDTRA 14075 §6-1, §6-5)
