DSAF is the heat-extracting component
from cockpit and is mounted in the climate
maintenance box.
In order to cool the cockpit, the warm air
must be absorbed and redistributed the
“cooled“ air. The warm air is going over the
evaporator to, which is transmitting part of the
temperature, this one being gradually reduced.
In the same time, the refrigerant fluid which
is passing through the evaporator piping is
absorbing the heat from the air going over the
evaporator and at the same pressure, is
transformed from fluid to vapors. When coming
out from evaporator, the refrigerant fluid is in
vapor condition.
