The main function of the condenser is

• A. To remove heat from the refrigerant
• B. To compress the refrigerant
• C. To store the refrigerant
• D. To absorb heat from the space

Answer: (A)

The condenser's job is to reject heat from the refrigerant to the surrounding environment so it can condense from a high-temperature vapor into a liquid. After the compressor raises the refrigerant's pressure and temperature, the hot, high-pressure vapor flows through the condenser, where it releases heat to air or water. That heat rejection is what lets the refrigerant change phase and become a liquid, ready to be metered and evaporate again in the evaporator. The compressor is the part that increases pressure, storing refrigerant isn’t a function of the condenser, and absorbing heat from the space happens in the evaporator, not the condenser.
