Introduction
Liebert HPS is the high performance split air conditioner family designed to assure proper environmental conditions inside
technological environments, especially BTS and Node B for Mobile Networks.
It’s composed of the HPSE indoor ceiling mounted module coupled with the HPSC outdoor module.
It’s efficient thanks to the effectiveness air distribution reached through the displacement cooling concept; it’s energy and
space saving thanks to the high efficiency components and the compactness of the innovative free cooling version; it’s extremely flexible thanks to the possibility of selecting among several versions: Liebert HPS can be configured depending on
the main application drivers (noise level, allowed environmental conditions range etc.) and the desired option (free cooling,
emergency free cooling, heating etc.).
The Liebert H PS family is also available in the HPSW version, made of the SE_W indoor wall mounted moudule coupledwith
the HPSC outdoor module.

Features and Benefits
Distribute the air in the best way
The HPSE, ceiling mounted indoor unit is thought to send the cold air straightly down, close to
the racks suction area and intakes the hot air out coming from the heat sources, into the cabinet
sides (frontal and lateral).
In this way the mixing effect between conditioner cold air and electronic equipment hot air is
denied resulting in a double beneficial effect: the rack is fed by cold air where it is needed and
the air conditioner treats only the hot air maximizing its efficiency.
Proper temperature inside the racks, high efficiency of the cooling equipment , hot spot absence
in the site: distributing the air in a smart way is very effective.
Save energy and space
The use of the optional freecooling gives the possibility to stop the compressor and use the external fresh air to cool the site: the annual energy absorption, requested to cool the site, goes
sensibly down. The 0---100% fine modulation allows to keep constantly the desired set point inside the site.
No adding module is requested when using the HPSE ceiling mounted indoor unit: the innovative
rotary freecooling system keeps unchanged the requested space to install the unit.
Use the additional freecooling module to have the wall mounted (SE_W) solution.

Longpiping
Remote nodes need to exchange data continuously, always working at proper environmental
conditions.
Therefore the air conditioner reliability is not an option: it’s a must.
The most modern design and components such as scroll compressor and plug---type fans, heat
exchanger surfaces and airflows generously designed allow the unit to work 24h/day, 365 days.
Maximize the unit reliability selecting the emergency cooling option: in case of main supply fault
the air conditioner is supplied by alternative energy sources like 48 VDC batteries or independent
AC generator.
Start ---up quickly and easily the site
Liebert HPS is ceiling mounted (HPSE) or wall mounted (SE_W): 2 rows with screws have to be
used to easily fix the unit to the site ceiling or wall. No internal wiring of the air conditioner is requested thanks to the availability of the fast plug electrical connectors (special on request).
The auto test software checks automatically all the main components operations, speeding up
thesitestartupprocedure.
Choose the cooling unit suitable to your application
Liebert HPS assures optimal air distribution, efficiency, energy saving, reliability, compactness
whatever is its configuration. More stringent requirements in terms of noise level emission and
maximum external working temperature, can be satisfied selecting HPSC advanced version: 45
dB(A) at 3m f.f and 50˚ C with internal conditions of 27˚C, 35% R.H. at 1.5m from site floor.
Long piping installations are not anymore a limit: using the “L” condenser version, high performances are assured also when distance between outdoor and indoor unit is prohibitive.
Respect the environment: ODP, TEWI and . . . noise level
Now days green refrigerants are a standard (low Ozone Depletion Potential)! More than this, the
most effective way to respect the environment is to reduce the energy absorption with a high efficiency refrigerant cycle.

Liebert HPS---PD---272965---20.11.2009
Liebert HPS reach a high EER (Energy Efficiency Ratio) value thanks to the use of large surface
heat exchangers; this effect is maximized by the U ---Shape coil used in the evaporating side. The
relevant Total Equivalent Warming Impact (TEWI) value is reduced.
Finally the importance of a low noise level: a different way,not less important, to respect the environment.

Mechanical Specifications
Refrigerant circuit
The compressor, located in the moto---condensing section, is hermetic, scroll type, complete with
internal protection against overheating. It is housed in a compartment separated from the air flow,
protected by an insulated panel, accessible from the front side for complete maintenance.
A crankcase heater maintains a minimum refrigerant temperature to allow reliable start--- up and
operation even in very cold climate. Depending on the configuration a capillary or a thermostatic
expansion valve, filter dryer and sight glass, low pressure and high pressure switches and two
access valves complete the refrigerant circuit.
Evaporating section
The evaporator section consists of a coil with copper
tubes and aluminium fins, with a large face area in order to increase the SHR (Sensible Heat Ratio) and optimize the EER (Energy Efficiency Ratio).
The U---shape coil in the ceiling mounted unit, increases the heat exchange efficiency.
A galvanized steel condensate drain tray
(10/10mm thick) is provided.
Depending on unit version, evaporating fan(s), all direct driven, can be axial (HPSE ceiling mounted, cooling only), centrifugal (SE_W only cooling) or centrifugal backward curved (HPSE ceiling or SE_W wall
mounted, Freecooling and Emergency Freecooling).
Fans are statically and dynamically balanced with
self---lubricated bearings, equipped with an airflow
sensor as standard to provide an alarm in case of low
airflow.

Condensing section
A wide surface condensing coil is provided. It is designed in copper tubes with aluminium fins and sized
to allow operations at least up to up to 45˚C outdoor air temperature.
The ”Advanced” version extends the external high temperature limit to 50˚C in order to satisfy
extreme environmental working conditions. The units are equipped with 6---pole axial fan. The
electrical motor is directly coupled on the motor shaft, with internal thermal protection and IP54.
The innovative design of the impeller allows the maximum efficiency with the minimum noise.
In Liebert HPS standard, the condenser fan is activated together with the compressor; a simple and valid solution where the required noise level is not extremely low (50 dB(A) at 2m f.f), where
the temperate climate doesn’t required to work in extremely low
environment conditions (10˚C), where using the freecooling you
can save your energy and go down to ---30˚C.
In the ”Advanced” Liebert HPS, the condensing fan speed is
smoothly regulated by a modulating control; it is the ideal solution if the freecooling is not allowed and the air conditioner is required to work in mechanical mode down to ---30˚C; it’s a must
where extremely low noise level is required. Keeping the Advanced performances, the long piping version extends the allowed
distancebetween the evaporating and condensing unit (see Fig.
22, Fig. 23, Fig. 24 and Fig. 25).

Filtering section
The filter section is placed vertically, before the evaporating coil and provides filtration of the internal ambient and the fresh air to obtain the required degree of air cleanliness in the room. The
filter can be removed from the bottom of the unit (indoor side) simply opening the relevant panel
and unlocking the support brackets. The standard filter class is G3, according to Eurovent EU4/5
standard. A metallic pre --- filter, enclosed in the freecooling air intake grill (accessory), protect the
fresh air filter.

Options
Emergency cooling
The unit is optionally equipped with an emergency cooling system that allows to ventilate or to
cool through external fresh air the site in case of main electrical supply fault.
For this purpose the evaporating fan section, the control, and the free cool ing damper are supplied in 48 VDC power supply (from rectifier in normal mode, from batteries in emergency mode).
This option guarantees the air circulation inside the site and if the control recognizes the proper
external temperature to run the freecooling mode, the damper will open to fresh the site and get
the required set point. The emergency cooling system is also available in 230 VAC.
The compressor and the condenser fan are supplied by standard AC power.
Heating
The heating option include electric heaters (1.5 kW on model 06, 3.0 kW on models 08 --- 10, 4.5
kW on model 12 and 6.0 kW on model 14), located in the air discharge plenum, one stage and
ON--- OFF regulation.
A safety thermostat, with manual reset, prevents from reaching dangerous temperatures.
Freecooling
The freecooling system consists of a damper controlled and moved from a AC servomotor
(48VDC supplied in the emergency version).
The system allows a 0 ---100% modulating freecooling in order to respect the desired set point.
The exhaust air is discharged outdoor through an overpressure damper mounted on the wall and
available as accessory. The control allows the unit to run in freecooling mode when the difference
between the indoor and outdoor air temperature reaches the required value to get the nominal
cooling capacity. In emergency situation, the freecooling is allowed at a lower difference between
the indoor and outdoor air temperature, in order to use the external fresh air as much as possible.
In the HPSE ceiling mounted version, the innovative rotary system allows the air conditioner to
be equipped with the freecooling system without any adding module, maintaining the standard
unit dimensions.
