ABB Reveals Ways to Squeeze Greater Efficiency
from HVAC Applications
At EMEX 2017, ABB’s stand features eBooks, demos and products highlighting the savings
achieveable and the pitfalls to avoid with the latest drive technology
n eBook written to help users
of variable speed drives (VSD)
efficiency of heating, ventilation and
air conditioning (HVAC) applications
will be launched by ABB at The
Energy Management Exhibition
(EMEX), stand E20, 22-23 November,
ExCel, London.
It is the latest in a series of eBooks
created by ABB to tackle the technical
challenges facing users of VSDs in the
HVAC industry.
Not all drives count energy use … and
why it matters
Today’s VSDs offer a wealth of features
and smart functions that enable users to
optimise the efficiency of pumps, fans
and other motor-driven applications. For
example, onboard counters show
exactly how much energy is used
compared to direct-on-line (DOL) control
methods and can play a key role in
securing management funding for future
efficiency projects.
Using the least amount of energy
The eBook showcases advanced motor
control features, such as energy optimisation (also known as flux optimisation),
which help ensure that motors are controlled using the least amount of energy.
With energy optimisation, the magnitude of the motor’s magnetic field is
controlled according to the actual load
and across the speed range to minimise
energy being used at all points, thus
saving energy constantly throughout
the lifetime of an application.
Another energy saving feature is a
statistical tool that analyses and
interprets drive behaviour including
process energy efficiency and operation.
The analyser provides information on
system maintenance needs and can be
used to illustrate and control the
system’s energy efficiency. It allows
users to identify periods of unexpectedly
high (or low) load and can point towards
system optimisation improvements.
savings that are achievable using VSDs.
This includes an energy efficiency demo,
which uses a balloon to show the cube
law principles behind the VSD, that is
reducing motor speed by only 20 percent
decreases energy consumption by up to
50 percent.
The superior efficiency of the ABB HVAC
drive, the ACH580, will be showcased
with an on-stand demonstration of the
drive and a synchronous reluctance motor
(SynRM) package.
The ABB HVAC drive has the highest
efficiency class for a drive and provides
superior efficiency with all motor types,
including induction, permanent magnet
and SynRM. When partnered with ABB’s
IE4 SynRM motor the ABB HVAC drive
achieves energy savings of up to 60
Another exhibit will demonstrate the
ACH580’s intelligence and BACnet
interoperability by simulating the functions
of an air handling unit. The drive
integrates with a touch panel simulating
a BMS operator workstation via BACnet,
while the drive’s intelligence is used to
control external devices, including a
three-way valve and an air damper.
A touchscreen kiosk gives visitors the
opportunity to try out ABB’s Zenon
supervisory control and data acquisition
(SCADA) system. With over 300
supported communication protocols,
plus easily configurable interfaces for
connection with business planning and
cloud-based systems, Zenon can be
readily integrated with a building
automation system.
Hear from the experts
Experts from ABB’s energy team will be
on stand offering advice on how to
optimise the energy efficiency and
reliability of HVAC applications with the
latest VSDs, electric motors and life
cycle services, including an ABB energy
In addition, ABB’s John Guthrie will
outline the important issues that must be
considered when undertaking an energy
assessment of motor-driven applications
in order to avoid getting hit with
unexpected costs. His presentation will
take place on Thursday 23 November
2017, 10:30-11:00 in the Facilities,
Technology & Innovation Theatre.
