6.15 SYSTEM WATER CLIMATIC CURVES
Set point compensation on outdoor temperature
Summer
With outside low temperatures the refrigerant requirements are
reduced. The internal comfort can also be obtained with a set-
point higher than standard. The correction is added to the set-
point (increased with the decrease in temperature).
Winter
With outside mild temperatures the thermal requirements are
reduced.
The internal comfort can also be obtained with a lower set-
point.
The correction is subtracted from the set-point (increased with
the decrease in temperature).
Example:
if outside temperature (T. Ext.) > 114, set water = par 52 -117
