Seasonal
performance, cooling mode
Most central air conditioning systems installed in the tertiary sector in Europe use water chillers to provide refrigeration.
Analyses of installed systems show that the heat load varies from season to season and that a water chiller operates at reduced
capacity for the majority of the time.
The European Seasonal Energy Efficiency Ratio (ESEER) measures the seasonal efficiency of water chillers by taking into
account their efficiency under partial load using formulas created by the European certification body Eurovent.

ESEER = A x EER100% + B x EER75% + C x EER50% + D x EER25%
A, B, C and D are weighting coefficients pertaining to a unit's running time based on its load
The ESEER design conditions for air-cooled water chillers are as follows:

The efficiency under partial load is therefore essential when choosing a water chiller. It is with this in mind that the new
AQUACIATPOWER range was designed. In particular, the entire range uses R410A refrigerant which, thanks to its thermodynamic
performance, makes it possible to obtain much higher ESEER ratings.
As its compressors are connected in parallel on the refrigerating circuit, the AQUACIATPOWER easily and efficiently adjusts the
cooling capacity to the system's needs. The self-adjusting Connect Touch control anticipates variations in load and starts only
the number of compressors needed. This ensures optimum operation of the compressors and guarantees energy efficiency for
the majority of the system's life.
The high seasonal energy efficiency AQUACIATPOWER HE series has EC-type variable-speed fan motor assemblies as standard.
This technology enables the machine's performance at partial loads to be improved, along with its ESEER.

Seasonal
performances in heating mode
The European Ecodesign directive takes into account the
product's environmental impact throughout its life cycle. It
defines the mandatory energy efficiency requirements for water
chillers and heat pumps.
Products that do not meet the energy efficiency requirements
set by the new directive will gradually be phased out of the
market, forcing manufacturers to develop and offer more
efficient products.
Like the ESEER relating to water chillers, the new seasonal
coefficient of performance (SCOP) resulting from this new
European directive is used to evaluate the energy efficiency
of heat pumps. Until now, only the COP has been used to
measure energy efficiency in heating mode.
The COP was exclusively calculated using a single measuring
point, and only took into account operation at full load, which
did not represent the efficiency of the heat pump over an entire
heating season.
The purpose of the SCOP is to characterise the seasonal
efficiency of the heat pump by taking into account the
efficiency at partial load and full load established for several
outdoor temperatures. The SCOP is the ratio between the
building's annual heating demand and the annual electricity
consumption of the heating system. It is measured in
accordance with the EN14825 standard based on an average
reference climate that takes into account several reference
temperatures between -10°C and +16°C
SCOP
■ Primary energy evaluation
In order to compare the energy efficiency of products using
different energy sources, the Ecodesign directive introduced
a new seasonal energy efficiency calculation known as Ƞs
(Greek letter eta followed by the letter "s" for seasonal) and
expressed as a percentage. For heat pumps, the SCOP (final
energy) value is transposed to Ƞs (primary energy) by taking
into account a conversion coefficient of 2.5 which corresponds
to the average efficiency of the electrical production and
various corrections for the responsiveness of the regulation
system (i = 3 for air-to-water heat pumps).
η s (%) =
SCOP(kW/kW)×100
∑
2,5
i
corrections
The minimum seasonal efficiency requirements to be met by low
temperature heat pumps, set by the standard, are as follows:
ηs = 115%, which is a minimum SCOP of 2.95 valid from
September 2015.
ηs = 125%, which is a minimum SCOP of 3.2 valid from
September 2017.
The AQUACIATPOWER ST series complies with the European
Ecodesign 2015 directive. The AQUACIATPOWER HE series
already meets the more stringent 2017 directive.

-The unit's hydraulic module and the water type heat exchanger may be
protected against freezing (factory-fitted option) using electric heaters and
heat trace cables (13)
-The pressure sensors are fitted on connections without Schraeder.
Depressurise and empty the system before any work.

Variable
flow pump
■ Description
■ SOFT START
The AQUACIATPOWER may be equipped with one or two
variable speed pumps which save you energy by adjusting the
electrical consumption of one pump to the actual requirements
of a hydraulic system, in particular for oversized installations.
A SOFT START function prevents any current peaks when
the pump is started up to protect the electrical system,
thereby limiting the building's electricity use at peak times and
ensuring the smooth operation of the pipework
■ Simple to use
■ STANDBY function
The "variable speed pump" is fully integrated on the machine,
with full protection, and, as it is installed outdoors, there is no
need for any work in the machine room.
Lowering the speed when the compressors are on standby
reduces the water flow rate to ensure the water loop is perfectly
homogenised and the control temperature sensors are well
irrigated. This reduces the pump's electricity consumption
by around 80% during standby periods, which represents a
significant proportion of the machine's normal operating time,
in particular for air conditioning applications.
The assembly is factory-fitted and pre-set on the unit; it is
therefore quick to install and reduces the cost of work, in
particular because there is no water flow control valve on the
unit's outlet.
The ability to adjust the water flow to your requirements means
that the pump pressure can be adapted precisely to the actual
pressure drop on the system when it is started up on-site.

■ Operating principle
- Operation at full load
A regulator, with a direct display of the flow rate and pressure on
the Connect Touch screen, enables one pump (pump A in the
example below) to be adapted, by lowering its pressure P1 to
the requirements of system P2, to obtain the optimal water flow
rate setpoint. Electricity bills relating to the pump's consumption
are reduced proportionately; this means you will see a return on
investment (ROI) in only a few years, compared with the same
fixed speed pump equipped with a simple flow control valve.

- Operation at partial load
There are three operating modes for partial load:
1 - Fixed speed
The control ensures the pump continuously runs at a constant speed, based on the
capacity of the compressor(s). When the compressor is powered off, the Connect
Touch "standby" function manages the electrical power consumed by the pump by
reducing its speed to the minimum.

This provides energy savings of around 33%.
2 - Variable flow rate: Constant regulation of the pressure difference
The control continuously acts on the pump speed to ensure a constant pressure difference (delta P). This solution is suitable
for installations with two-way valves. This control mode is used to ensure a uniform supply in each hydraulic circuit to make
sure that each terminal unit operates at a satisfactory pressure
3 - Variable flow rate: Constant regulation of the temperature difference
The regulation maintains a constant temperature difference whatever the load rate of the unit by reducing the flow rate to
the minimum acceptable limit. This control mode is suitable for most comfort applications.
This provides energy savings of around 66% for the pump in each of these last two operating modes

Environmental
responsibility
The AQUACIATPOWER contributes to sustainable development
via an environmentally responsible approach, aimed at
balancing ecological and economic concerns. This enables it to
meet the requirements of future European thermal regulations
and to protect our environment for future generations.
- Asymmetrical PBHE brazed plate heat exchangers
The highly efficient performance it offers enables
energy consumption to be greatly reduced, thereby
reducing the unit's carbon footprint throughout its
service life.
•R
eduction in the refrigerant charge compared with a
tubular heat exchanger solution
•T
he asymmetrical technology enables a reduction in
pressure drops on the water side, and an associated
drop in electricity consumption.
This performance is the result of the high quality components
used, which have all been rigorously selected:
- The latest generation Scroll compressors
-H
ighly efficient R410A refrigerant, which has a low
environmental impact: zero ODP (Ozone Depletion Potential),
low GWP (Global Warning Potential).

Only 20% of a unit's impact on the ozone layer comes
from the refrigerant (direct effect), with 80% coming from
the CO2 released into the atmosphere when the electricity
required to power the unit is produced (indirect effect). With
AQUACIATPOWER, it's a win-win situation: its low refrigerant
charge minimises the risk of emissions, and its low energy
consumption limits its indirect impact.
12
2000
The choice of technology used in the AQUACIATPOWER range
means that the TEWI, which covers the unit's environmental
impact (both direct and indirect) throughout its service life, is
greatly reduced.

Partial
recovery with desuperheater
The AQUACIATPOWER range may be equipped as an option with an energy recovery function using a desuperheater
Heat from gases released by the compressors is recovered directly by a type of heat exchanger called a desuperheater located
on the unit to produce free, additional hot water.
This optional configuration requires assembly in our factories and is by order only.
■Refrigerating circuit diagram
Discharge C1
This refrigeration diagram illustrates a unit with a
desuperheater on each refrigerating circuit. For heat
recovery to be possible, the unit must be operating. For
the same cooling capacity, the desuperheater provides
a source of free hot water and lowers the unit's electrical
power consumption.

C1: Refrigerating circuit no.1
C2: Refrigerating circuit no.2
■Hydraulic connections: configuration and precautions
The hydraulic supply for each desuperheater is delivered
in parallel. In order to ensure that the unit can start and
operate under the correct conditions, the desuperheater
circuit water loop must be as short as possible and be
able to increase quickly in temperature. The minimum
desuperheater water inlet temperature must be 25°C. It
may require the use of a three-way valve with its
controller and a sensor controlling the minimum water
inlet temperature.
Note:
The water loop for the desuperheater circuit must include an
expansion vessel and a valve. Special attention should be
paid when selecting the expansion vessel as the recovery
water circuit can reach 120°C if the pump is turned off or if no
hot water is consumed

Xtra
fan operating pressure ventilation
The AQUACIATPOWER HE version range can be equipped as an option with XTRAFAN operating pressure ventilation.
■ Functions
■ Precautions for installation
The XTRAFAN offers a wide range of functions, making a
whole host of flexible installation conditions possible, such as:
On-site installation of a reversible air-to-water packaged unit
requires some safety measures to be taken, particularly if it
is installed in a machine room. For example, the condensate
draining must be specific to these units, particularly for when
outdoor temperatures are very low.
-T
he option of installation in a confined space, for example
on a terrace surrounded by walls, where only an air supply
with static pressure of between 100 and 200 pascals within a
duct enables use without recirculation or mixing of air at the
condenser intake,
- Installation in an urban area in which noise is a particular
issue, where operation is only possible by adapting a sound
trap to the supply air,
-
A self-adjusting variable speed function which allows «allseason» cooling, fully secured for industrial processes,
including during harsh winter conditions with an external
temperature of -20°C,
-T
he freedom to precisely adjust the ventilation speed on-site
to what is «strictly necessary» to obtain the optimum air
supply pressure, or the maximum acceptable noise level for
the site on which the unit is located,
During defrosting cycles, reversible units are liable to discharge
a large amount of water onto the ground, which must be
drained, as well as steam from the fan discharge which can
damage the supply air ducts. The ground supporting the unit
must be perfectly watertight and capable of collecting and
draining the defrosted water, including during freezing periods.
It is also recommended that the unit is raised by approximately
300 mm.
If an air discharge duct is installed on site, its weight must
not be supported by the roof of the unit. Each fan must be
connected independently..
The duct must be connected to the unit using a flexible supply
air sleeve, included in the option.
-
An improvement in the EER and electrical consumption
for the unit, in direct proportion to the load required by the
installation.
The various performances (cooling capacity, heating capacity,
input power, energy efficiency) depend on the rotation speed
of the fans, and therefore on the desired operating pressure
in the duct:
-
At an operating pressure of between 0 and 100 Pa, the
machine performances are barely affected
-
At an operating pressure of between 100 and 200 Pa,
the machine performances may be significantly affected,
particularly according to the air and water temperature
conditions.
The noise level at the duct outlet and that radiated around the
machine depend on the operating pressure.
Refer to the selection tool to assess the estimated impact of
the duct system on the machine’s operating conditions.

Intelligently-designed
acoustics
To comply with the various restrictions on integration, the
AQUACIATPOWER has two sound finish levels enabling it to
be easily integrated into a number of zones without causing
disruption to users or their neighbours.
■ Basic version
The distinguishing feature of the AQUACIATPOWER range
is its rigorous design incorporating "noiseless" assembly
techniques to reduce vibrations and sources of noise:
■ Night mode
The AQUACIATPOWER has a Night Mode enabling the sound level
to be limited at night or when the building is unoccupied (according
to the user programming) by controlling the output and the fan
rotation speed.
■ Acoustic signature
As important as the sound power level, the acoustic signature
reflects the noise disturbance generated by the unit.

acoustic studies in our Research and Innovation Centre.
Each fan is equipped with an air current rectifier deflector
which ensures a linear flow of air with no turbulence, whilst
reducing recirculation and keeping the acoustic spectrum
within a pleasant range.

-T
he Connect Touch controller automatically adjusts the
fan air flow rate according to the outdoor air temperature
and the unit's load rate which enables the sound level to
be significantly reduced, particularly at night, mid-season,
morning and evening, which totals more than 75% of the time
the unit is used.
t
■ Low Noise option
The AQUACIATPOWER HE series has variable speed motors
fitted as standard to all of the fan motor assemblies.
In this version, in addition to the basic equipment, the
compressors are fitted inside soundproofed casing lined with
absorbent material to limit the sound level emitted by the
machine.
AQUACIATPOWER ST series units equipped as an option
with variable speed motors (all-season operation) have one
variable speed fan motor per refrigerating circuit.
■ Xtra Low Noise option
In this version available from the HE series, the compressors
are housed in sound boxes identical to those in the Low Noise
version and the fan rotation speed is reduced whilst ensuring the
output and thermal performance remain optimised.
The variable speed control can be used to soft start the fans.
It avoids the increases in noise linked to the on/off sequences,
thereby improving the unit's acoustic signature.
Similarly, the installation of a variable speed pump enables
the sound level of the pump function to be reduced by
adjusting the pump speed to what is strictly necessary.
The soft start improves the signature and reduces
nuisance noise.
With all these benefits and its three acoustic finish
levels (Standard, Low Noise and Xtra Low Noise), the
AQUACIATPOWER can be integrated into any site, ensuring
any constraints in terms of the sound environment can be met.

evaporator water flow rate
The Connect Touch control is equipped with anticipation logic making it highly flexible in adjusting operation to parameter drift,
particularly on hydraulic systems with low water volumes. By adjusting compressor runtimes, it prevents short-cycle protection
cycles from starting and, in most cases, eliminates the need for a buffer tank.
Note The minimum volumes of chilled water are calculated for EUROVENT rated conditions:
Cooling mode
- Chilled water temperature = 12°C/7°C
- Outdoor air temperature = 35°C
Heating mode
- Hot water temperature = 40°C/45°C
- Outdoor air temperature = 7°C
This value is applicable for most air conditioning applications (unit with fan coil units).
Note:
For installations running with a low volume of water (assembly with air handling unit) or for industrial processes, the buffer tank
is a required component.

Operating
range
AQUACIATPOWER devices have a broad field of application, enabling them to meet a range of heating and cooling requirements
in the most varied of climates.
Multi-climate:
Cooling mode from -20°C to +48°C
The AQUACIATPOWER HE series is equipped as standard with all the management devices and algorithms to enable all-season
operation in all climates. The AQUACIATPOWER HE series is therefore able to operate in conditions ranging from the heat of the
Mediterranean basin to the chill of Scandinavia, the humid Atlantic coast to the dry climate of Central Europe.
In the ST series, all-season operation down to - 20°C is optional.
Heating mode from -10°C to +35°C
The design of the AQUACIATPOWER makes it suitable for the majority of heating and air conditioning applications, regardless of
the climate. Water heated to +40°C is guaranteed, even for outdoor temperatures of -10°C.
Multi-application: air conditioning, industrial processes

Installation
recommendations
■ Water quality criteria to be respected
-e
lectrical power supply to unit
Warning: It is essential that an 800-micron water filter be placed
on the unit's water inlet during installation. The quality of the
water used has a direct impact on the correct and compliant
operation of the machine and its service life. This is particularly
true if the water used clogs or corrodes components or
promotes the growth of algae or micro-organisms. The water
must be tested to determine whether it is suitable for the unit.
It is also tested to determine whether chemical treatment is
necessary and will suffice to make it of acceptable quality. This
analysis should confirm whether or not the various machine
components are compatible with the water they come into
contact with on-site.
-c
ontacts available as standard enabling the machine to be
controlled remotely (optional)
Warning: failure to follow these instructions will result in the
immediate voiding of the unit's warranty.
■ Lifting and handling
The utmost safety precautions must be taken when lifting and
handling the unit.
It should be noted that the unit's electrical system is not
protected against lightning strikes.
Therefore devices to protect against transient voltage surges
must be installed on the system and inside the power supply
unit.
■ Pipe connections
You must follow the instructions in the manual. All pipes must
be correctly aligned and slope toward the system's drain
valve. Pipes must be installed to allow sufficient access to the
panels and fitted with heat insulation.
Pipe mountings and clamps must be separate to avoid
vibrations and pressure on the unit. Water flow shut-off and
control valves must be fitted when the unit is installed.
Pipe connections to be made on-site:
Always follow the lifting diagram on the unit and in the
instruction manual.
-w
ater supply with pressure-reducing valve
Before attempting to lift the unit, make sure the path leading
to its intended location is free from obstacles. Always keep
the unit vertical when moving it. Never tip it or lie it on its side.
The following are a few examples of accessories essential to
any hydraulic circuit, which must also be installed:
-e
vaporator, condenser and drain
-w
ater expansion vessel
- drain nozzles at pipe low points
■ Choosing a location for the unit
-e
xchanger shut-off valves equipped with filters
AQUACIAT
units are designed for outdoor installation.
Precautions should be taken to protect them from freezing
temperatures. Special attention should be paid to ensure
sufficient free space (including at the top) to allow maintenance.
The unit must be placed on a perfectly level, fireproof surface
strong enough to support it when ready for operation. Noise
pollution from auxiliary equipment such as pumps should be
studied thoroughly.
-a
ir vents at pipe high points
Potential noise transmission routes should be studied, with
assistance from an acoustical engineer if necessary, before
installing the unit. It is strongly recommended that flexible
couplings are placed over pipes and anti-vibration mounts are
fitted underneath the unit (equipment available as an option)
to reduce vibrations, and the noise this causes, as much as
possible.
-P
lace the expansion vessel upstream of the pump.
POWER
■ Fitting accessories supplied separately
A number of optional accessories may be delivered separately
and installed on the unit on site.
You must follow the instructions in the manual.
■ Electrical connections
You must follow the instructions in the manual. All information
concerning electrical connections is stated on the wiring
diagrams provided with the unit. Always follow this information
to the letter.
-c
heck the system's water capacity (install a buffer water tank
if necessary)
- flexible couplings on exchanger inlets and outlets
Warning:
-P
ressure in the water circuits below 4 bar for units equipped
with the hydraulic module.
-D
o not place any valves on the expansion vessel.
-M
ake sure the water circulation pumps are placed directly at
the exchanger inlets.
-M
ake sure the pressure of the water drawn in by the
circulation pumps is greater than or equal to the required
minimum pressure (NPSH), particularly if the water circuits
are "open".
-T
est the water quality in accordance with the relevant
technical specifications.
-T
ake the necessary precautions to protect the unit and
hydraulic system from freezing temperatures (e.g. allow
for the possibility of draining the unit). If glycol is added to
prevent freezing, check its type and concentration before
system start-up.
-B
efore making any final hydraulic connections, flush the
pipes with clean water to remove any debris in the network.
Electrical connections must be made in accordance with best
current practices and applicable standards and regulations.
Electrical cable connections to be made on-site:

■ System start-up
■ Maintenance operations
CIAT or a CIAT-approved firm must perform system start-up
on the units.
Specific preventive maintenance operations are required at
regular intervals and should be performed by CIAT-approved
contractors.
You must follow the instructions in the manual.
List of system start-up checks (non-exhaustive):
- Correct positioning of unit
- Power supply protections
- Phases and direction of rotation
- Wiring connections on unit
- Direction of water circulation in unit
The operating parameters are read and noted on a "CHECK
LIST" form to be returned to CIAT.
To do this, you must refer to and comply with the instruction
manual.
You must take out a maintenance contract with a CIATapproved refrigeration equipment specialist. Such a contract
is required even during the warranty period.
