Fresh air temperature variations on the
change of the external air temperature
The following charts allow to determine
the variation of the temperature within
the room on the variation of the external
conditions. The variability of the air fl ow
is that allowed to guarantee that the
refrigerating circuit operates correctly.
N.B.
The following diagrams are typical for
all sizes, but without accessories
