The main function of the condenser in a refrigeration system is to remove heat from the refrigerant.

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

Answer: (A)

In a refrigeration cycle, the condenser’s job is to reject heat from the refrigerant. The hot, high‑pressure gas coming from the compressor releases its heat to the surrounding air or cooling water and condenses into a liquid. This heat rejection is what lets the refrigerant drop in temperature and change phase, so it can continue through the cycle and be expanded to a low-pressure, cold liquid in the evaporator. The other functions don’t fit: the compressor’s role is to raise pressure and temperature, not remove heat; the condenser doesn’t store refrigerant; and absorbing heat from outdoors describes the evaporator’s job, not the condenser.
