condensation temperature Co/tc are displayed after
evaporation and condensation are complete.
Zeotropes (refrigerants blends mix together) can separate
from each other, unlike azeotropes which mix together to
become one. Zeoptropes often blend refrigerants with
different boiling points (saturation temps), where one will
change from liquid to vapor before the other as they go
through the evaporator. The glide is the difference between
the lowest boiling point and the highest boiling point. If they
are 3 degrees apart, for example, the blend has a 3 degree
glide..
The display illumination will flash if:
• The critical pressure of the refrigerant is within 15 psi (1 bar)
of the highest pressure (and temperature) where the
refrigerant can still condense.
• The maximum. permissible pressure of 870 psi (60 bar) is
exceeded.
