What is the primary function of an induced-draft air-cooled condenser?

The primary function of an induced-draft air-cooled condenser is to suck air across the condenser coil. In an air-cooled condenser, the heat from the refrigerant is transferred to the air that is drawn over the condenser coil. The induced-draft design utilizes a fan to create negative pressure, which pulls outside air through the coil, enhancing the heat exchange process. This helps in effectively dissipating the heat from the refrigerant, allowing it to condense and return to the refrigeration system in a liquid state.

This is critical in maintaining the efficiency of the refrigeration cycle, as the cooling process relies on the removal of heat from the refrigerant. The use of fans in induced-draft configurations optimizes airflow and improves performance, particularly in environments where an efficient cooling process is essential.
