Featu res and Ben efits
Reliability and Low Environmental Impact
Reliability
The L i e b e r t H P C --- S 0 0 6 --- 0 2 2 series is equipped with two hermetic scroll com-
pressors, which represent state---of---the---art technology in this sector. They
have been designed and optimized for air---cooledwater chillers within aircondi-
tioning applications.
The high volumetric efficiency ensures excellent performances of the Liebert
H P C --- S 0 0 6 --- 0 2 2 units at full load operation and especially at partial load.
Extremely low noise operation and the absence of vibrations aid the installation
of the unit in city sites requiring strict noise limits.
The wide operating range, bearing lubrication, component oversizing, absence
of vibrations and few moving parts, together with the resistance to liquid slug-
ging and compressor electronic control integrated with the machine micropro-
cessor enhance the well---known characteristics of operating reliability and long
life typical of this compressors type.
AllL i e b e r t H P C --- S 0 0 6 --- 0 2 2 units are run tested at thefactory before shipment.
High outdoor temperature
The oversizing of heat exchangers and the wide operating range of the scroll compressors permit the
use of L i e b e r t H P C --- S 0 0 6 --- 0 2 2 units in high temperature environments as well, up to 46° C at 100%
full load.
Resistance to liquid slugging
The robust design of the scroll compressors can tolerate/withstand amounts of liquid refrigerant that
would severely damage reciprocating compressor valves, piston rods and cylinders.
Low Sound Emission
The L i e b e r t H P C --- S 0 0 6 --- 0 2 2 series is characterized by unrivalled low sound emissions.
Compressors supported on anti---vibration mounts and positioned in a closed compartment, common
to all versions; fans specifically designed to reduce the sound emissions, a special compressor jacket
on the “B” version “models from C/FB0 011” (Digit 11 = B or D) and “G” version with 900 mm fans, and
also a special compressor’s box insulated on the “G” version with 800 mm fans “models from C/FG0 011”
allow the achievement of such performance.
All the models are equipped with stepless fan speed control, thanks to a special algorithm on the iCOM
board, the fan speed could be kept to the minimum. It is possible to reach even lower sound emissions
with EC fans (electronically commutated fans), which especially during reduced speed operation, allow
noise levels around 50% lower than the values measured at the same conditions with traditional fans.

Unequalled Efficiency and Energy Saving
The use of hermetic Scroll compressors of the latest generation; plate heat exchanger evaporators selec-
ted for R410A application; aerodynamic profiled blade fans with high efficiency nozzles; large surface
condenser coils ensure the achievement of unequalled efficiency figures.
Freecooling Module
The “Freecooling” execution allows L i e b e r t H P C --- S 0 0 6 --- 0 2 2 to take advantage of low outdoor air tem-
peratures in the water cooling process in order to save energy, by avoiding compressors running.
A three---way valve arrangement permits the coolant to be diverted via the additional heat exchangers
before being fed into the cooling evaporator.
This means that even if the outside ambient temperature is not low enough to provide the complete cool-
ing load, a significant contribution to the running costs of the system can be made whenever the ambient
temperatures falls below the coolant inlet temperature.
Reduced space requirements in comparison with a conventional chiller plus a dry---cooler, are obtained
through the “Freecooling” execution’s compact design and the reduction of the compressors working
hours offers exceptional saving both in the long and short term.
The different strategies adopted by the proprietary microprocessor control in managing the various com-
ponents, fans --- compressors --- regulation valves, and operating modes, mechanical and/or free cool-
ing, together with the compressors’ partialisation ensure typical energy savings greater than 30%.

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 resources (compressors 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
could 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.

Liebert HPC---S 006---022---PD---273571---01.03.2012
The solution is @connectivity, which is a highly sophisticated way to let the system components (the
Air---Conditioners as well as the L i e b e r t H P C --- S 0 0 6 --- 0 2 2 units, Chiller and Freecooling executions)
talk to each other.
The @connectivity plug---in allows the setting of different working modes for different situations, such
as:
Dhigher water temperature in low load operation (energy saving);
Dlower water temperature for dehumidification (better performance);
Dspecial ”night” Setpoint (energy saving & noise reduction);
Dlower water temperature if one or more Air Conditioners fail (keep capacity in emergency situations);
D...andmuchmore!
To add the @connectivity to your system, it is simply necessary:
To build up Hironet connection between the room units and the L i e b e r t H P C --- S 0 0 6 --- 0 2 2 units. The
network can be only 1 (if the distance and the number of units allow this) or it can be split in several net-
works.
On @connectivity it is possible to define the rules that you want your system to respect.
It will be then up to the web capabilities to allow the view and control of your system from any PC of your
Local area network (provided that the @connectivity PC is connected on the LAN) or even if you have
a connection to Internet and your system is open to external access, you will have the possibility to view
and control your system via Internet
Flexibility: Hydronic Module
In ordertomatch different kinds ofinstallations and ap-
plications, Liebert HPC-S 006---022 units
are available with a hydronic mod-
ule, which can be adapted/ad-
justed depending on the specif-
ic requests.
Based on this philosophy, the
units can be equipped with
everything that is needed for
the correct installation and, in
this way, reduce the complexity
of the commissioning: buffer
tank, 1 or 2 circulating pumps,
water filter, safety valve, expan-
sion vessel, flow switch. With all
these elements included inside
the unit, it is just a matter of con-
necting the chiller to the sys-
tem.
But, if some or all of these com-
ponents are already present in the hy-
draulic line, Liebert HPC-S 006-022 can
be equipped only with what is not already con-
nected in the system. This level of flexibility allows true customisation of the unit.
Compactness: Small Footprint
The L i e b e r t H P C --- S 0 0 6 --- 0 2 2 series achieves the high efficiency performance and low sound emission
previously described with a compactness which is one the highest in its category.
This result ispossible thanks to the high quality components selectedand a design which takes into con-
sideration the different aspects and needs of a chiller installation.
In this way the installation area can be optimized, leaving more space for other building elements. Com-
bining this aspect with the possibility of including all of the hydronic components inside the unit, Liebert
H P C --- S 0 0 6 --- 0 2 2 series is really a leader in terms of easy and compact installation
