Which statement best describes the heat transfer roles of the evaporator and condenser?

• A. Evaporator removes heat; Condenser releases heat
• B. Evaporator releases heat; Condenser absorbs heat
• C. Evaporator compresses refrigerant; Condenser expands it
• D. Evaporator stores refrigerant; Condenser heats it

Answer: (A)

In this cycle, the evaporator is where heat is taken from the space being cooled into the refrigerant, causing the refrigerant to boil into a vapor. The condenser does the opposite: it rejects that heat to the surroundings as the refrigerant condenses from a vapor back into a liquid. So the evaporator removes heat from the space, and the condenser releases that heat to the outside environment.
