Seasonal Efficiency
The ”Freecooling” execution finds its best application in combination with the “Supersaver Evolution”
system which regulates the coolant temperatures according to the variation of the thermal load, increas-
ing the numbers of hours during which free cooling is possible.
The percentage of energy saving can thus be greater than 35%.

Integration with Indoor Air Conditioners
Supersaver Evolution System
A special working mode can be set up in combination with Emerson Network Power HPAC indoor units
to obtain the ”Supersaver Evolution” system, that enhances the energy saving capabilities and thus op-
timizes the SEER (Seasonal Energy Efficiency Ratio) of the system.
Through @connectivity the information on the cooling needs of the air conditioners is available to the
L i e b e r t H P C --- S 0 0 6 --- 0 2 2 units, that will manage their resourc e s (compresso rs and free cooling) in the
most efficient way in order to save addition-
al energy.
This solution does not require any
modification, mechanical or
electrical thus avoiding ad-
ditional components
and regulation al-
gorithms which
coul d undermine the
reliability of the sys-
tem.
@ Connectivity
When the room units
are equipped with
thesametypeofcon-
trol system Emerson
Network Power
(iCOM and CDL), it is
possible to maximize
the energy savings and im-
prove the total operation man-
agement.
