 BE CAREFUL OF DEWING AND
FROSTING
As shown in the Figure, suppose a high temp absorbing air condition
A and a low temp absorbing air condition B are plotted on the air line
figure, then a high temp air A is heat-exchanged by the unit and goes
out of the saturation curve as shown by Point C.
In this case, the unit will be dewed or frosted.
To aboid this, you are required to heat a low temp air B up to B' so as
to get C' below the saturation curve, before using the unit.
