2.1.5 Air-Cooled Condenser Section

The air-cooled condenser section (Figure 2-4) consists

of the condenser fan, condenser coil, receiver with sight

glass/moisture indicator, quench valve, liquid line

service valve, filter-drier, condenser pressure

transducer, and fusible plug.
The condenser fan pulls air in through the bottom of the

coil and discharges it horizontally out through the

condenser fan grille.
