The function of a condenser fan in a refrigeration system is to dissipate heat from the condenser coils. When the refrigerant passes through the condenser, it changes from a gas to a liquid, releasing heat in the process. The condenser fan aids in this heat exchange by blowing air across the condenser coils, enhancing the cooling effect. This airflow helps to remove the heat absorbed by the refrigerant and prevents the coil from overheating, which is essential for efficient system operation. Proper heat dissipation is crucial, as insufficient cooling can lead to high-pressure conditions and reduced efficiency in the refrigeration cycle.
