What is the purpose of the condenser coil in an A/C system?

The purpose of the condenser coil in an A/C system is to release heat from the refrigerant to the outside environment. When the refrigerant, which has absorbed heat from the indoor air through the evaporator coil, enters the condenser coil, it is under high pressure and temperature. As the refrigerant flows through the condenser, it dissipates the heat it has captured and changes from a gas to a liquid. This cooling process is crucial as it allows the refrigerant to return to the evaporator coil, ready to absorb more heat from the indoor air, thus facilitating the continuous cycle of cooling.

This specific function of the condenser is vital for maintaining efficient operation of the air conditioning system. The other components mentioned each serve different roles: for instance, absorbing heat is primarily the function of the evaporator coil, while circulating refrigerant is a general role of the entire system rather than a specific function of the condenser. Similarly, compressing the refrigerant gas is the job of the compressor rather than the condenser itself.
