What is one of the main functions of a condenser in an HVAC system?

The function of a condenser in an HVAC system is primarily to reject heat from the refrigerant. In the refrigeration cycle, the refrigerant absorbs heat from the indoor environment as it evaporates in the evaporator coil. Once this refrigerant is compressed into a high-pressure gas in the compressor, it moves to the condenser.

In the condenser, the high-pressure gas dissipates its heat to the outside air or water, allowing it to transition back into a liquid state. This process is crucial because it prepares the refrigerant to return to the evaporator to continue the cycle of heat absorption. By effectively rejecting heat from the refrigerant to the outside environment, the condenser plays a key role in maintaining the overall efficiency and effectiveness of the HVAC system.
