What is the primary role of fan motors in refrigeration systems?

The primary role of fan motors in refrigeration systems is to circulate air over the evaporator and condenser coils. This circulation is crucial for the effective operation of the system. In the evaporator coil, the fan helps distribute cool air from the refrigerant throughout the space being cooled, ensuring that the desired temperature is achieved consistently and efficiently. Similarly, around the condenser coils, the fan assists in expelling heat from the refrigerant, enabling the system to reject heat as it changes from a gas to a liquid.

This process ultimately supports the refrigeration cycle's efficiency, ensuring that both heat absorption in the evaporator and heat rejection in the condenser are optimized. By maintaining a proper airflow, fan motors help prevent hot spots and ensure uniform cooling, which is essential for the overall performance and reliability of the refrigeration system.
