Air-cooled condensers
An air-cooled condenser is usually of the finned-tube type (Fig. 9.11),
with the refrigerant in the tubes and air forced over the outside of the
tubes and fins by a fan. Capacity control, if used, is accomplished by
cycling the fan, using a multispeed fan, or modulating airflow by
means of dampers. Refrigerant flow velocities must be designed to
prevent oil traps in the tubes. Capacities are based on square feet of
