Focus on your core business

All the Schneider Electric cooling resources can

therefore be linked* together in a network to

maximize the operating parameters and the current

required.

Row and room cooling units communicate to the

chiller, reducing the energy requirement by means of

a “tracking logic” for the current thermal load.

The chilled water temperature varies dynamically to

minimize compressor consumption and maximize

the use of free-cooling, while maintaining the

optimum temperature in the data center.

* Specific configuration may be required.

Cooling device integration:

The Optimize ManagementManagement of the whole system is the only way to optimize energy consumption and to implement integrated

control strategies.

Uniflair chillers are designed to integrate the main

electrical and hydraulic components onboard the

units.

In order to reduce the design and installation

phases, free-cooling circuit, primary pumps,

VSDs, and automatic transfer switches are

available to be factory installed

Choosing the best solution for pumps is certainly one

of the most important challenges for the designer.

Uniflair chillers have an onboard pump group which

can be inverter-driven.

Variable speed driven pumps integrated in the units

and driven by the chiller controller allow:

> Increased efficiency due to the continuous speed

adaption on the pressure drops of the circuit.

> Increased flexibility and modularity. It is possible

to change and adapt the available head pressure

from the chiller terminal, guaranteeing on-site

optimization and modular installations.

> Reduction in capital expense, since a single-

circuit design can be easily applied, saving the

extra cost for the additional devices typical of

primary/secondary circuits and manifolds, tanks,

and secondary pumps.

Prepackaged solutions

Variable speed driven onboard pumps

Thanks to this logic, the availability level is further increased since the usual single point of failure is removed, for

instance:

> The integrated ATS connects the unit to both the redundant power supplies. According to the line presence, the

unit manages the connection while the control board operates due to the integrated backup system.

> An additional external UPS* connection is available for critical components protection.

> The default network connection allows for group management without a master or external device which could

represent a critical item.

> The possibility to choose onboard pumps guarantees better availability when compared to single external pump

group.

All in One

* Specific configurations may be required.

Advanced control strategies

All the control software solutions for the Aqualflair range are developed by Schneider Electric and specifically

designed for each unit configuration, in order to manage all the aspects of the unit.

Self management

Double and/or separate power supply

When designing systems for which an uninterrupted service

must be provided, reliability is fundamental.

The possibility to connect the unit to a secondary power supply

guarantees advantages on controls, restarting procedures, and

maximize the operational reliability of the units.

Installing secondary lines on data centers is a standard

practice and Schneider Electric chillers are designed to offer a

complete range of solutions to integrate the unit into the

system.

Availability: the monitoring devices onboard the unit allows a

preventive maintenance and a check of the working operation while

the system is functioning.

Amperage monitoring: continuous supervision of the compressors

absorbed current to signal possible discrepancies with the default

values.

Precision: advanced algorithms to accurately control the chilled

water temperature.

Quick restart: Providing full cooling capacity within three minutes

after power failure, optimizing reliability and reducing the capital

expense thanks to the downsizing of backup water tanks.

Local area network: a shared control between all the available

resources for energy optimization and management of emergency

situations.

Connectivity: the unit sends alarms and data points to manage

critical building infrastructure from a single system. Additional

network interfaces provide management by connecting the device

directly to the network with a dedicated IP address. This eliminates

the need for a proxy such as a server. Monitoring is available via

Web browser with specific adaptor.

High temperature management

The BREC/F units are provided with modulating

condensation control:

> The influence of the external temperature variations on

the condensation pressures are managed by varying the

speed of the ventilating sections.

> In the event the external temperatures are such that the

maximum condensation pressure is reached even with

the fans at maximum speed, the control software

automatically reduces the capacity of the compressors,

consequently reducing the condensation pressure and

maintaining the unit in operation, even if with a lower

capacity (“Unloading procedure”).

Specific solutions for aggressive ambient conditions

Continuous cooling

Schneider Electric guarantees that all the chillers produced in the production

facility located in Italy are fully tested at the end of the production process

according to the relevant standards.

However, it is possible, with previous request, to check the unit performance

attending a Factory Admittance Test (FAT)*: these tests are carried-out on

the unit in specific climatic conditions, in the R&D laboratories in Conselve

(Italy).

* Feasibility, costs and dates to be agreed upon in advance with the R&D team of

Schneider Electric.

Functional and performance test

Units can be fitted with specific solutions in order to guarantee absolute

reliability in any climatic condition between -40°C (-40°F) and +50°C (+122°F),

including:

> Metallic coil filter for sand protection

> Cataphoresis treatment in order to protect the surfaces from corrosion

> Low ambient temperature option (standard for BREF models)

According to the ambient temperature, the chilled

water is partially or totally produced exploiting the

thermal exchange with the external air. This

significantly reduces the chillers energy impact.

When the external air temperature is low enough, the

microprocessor control system activates the free-

cooling pump, which circulates water inside special

heat exchange coils. Water is cooled by external air

brought in by the fans, which, together with the

pump, are the only components that absorb energy.

Free-cooling / EconomizerFree-cooling is an efficient method to reduce energy consumption at low outside air temperatures, enhancing

the energy optimization.

Intelligent

free-cooling (IFC)

Designing a reliable system means

choosing units which are both intrinsically

reliable and including “N+1” or “N+N”

redundancy logic.

With IFC, all the available units are

connected allowing chilled water to circulate

through all the free-cooling coils, thus

increasing the free-cooling surface and the

benefit in terms of thermal dissipation:

* Average values.

Designed for applications where the use of

glycol is not allowed in the data center, this

solution uses an intermediate heat

exchanger to limit glycol in free-cooling

circuit only, while using water in the main

circuit.

The careful selection and position of the

intermediate heat exchanger allows the

installation of the onboard main pump too, to

minimize the efficiency losses typical of

intermediate heat exchangers.
