Reading the objective operating conditions is useful for
checking the unit over time.
With unit of full load, namely in stable conditions and close to
those of work, take the following data:
- Voltage and general absorptions with unit at full load
- Absorption of varied electrical loads (compressors,
fans, pumps etc)
- Temperatures and capacities of different liquid (water,
air) in the inlet and outlet of the unit.
- Temperature and pressures on the characteristic points
of the refrigerating circuit (compressor discharge,
liquid, intake).
The readings should be stored and made available during
maintenance .

Set point compensation on outdoor temperature
Summer
With outside low temperatures the refrigerant requirements are
reduced. The indoor 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 indoor 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
