2.1.5 Air Cooled Condenser Section

The air cooled condenser section (Figure 2-4) consists of the condenser fan, condenser coil, receiver, sight glass/moisture indicator, liquid line service valve, filter-drier and fusible plug.

The condenser fan pulls air in the bottom of the coil and it is discharged horizontally out through the condenser fan grille.

This section also contains the economizer, economizer solenoid valve, economizer expansion valve and the liquid injection solenoid valve.
