A series of on-stand demonstrations highlight the intelligence of the latest variable-speed drive dedicated to HVAC applications.
A new variable-speed drive (VSD) dedicated to heating, ventilation and air conditioning (HVAC) applications, such as air handling units and pumps, was unveiled by ABB at The Energy Management Exhibition (EMEX), stand D20, 16-17 November 2016, ExCel, London.
The ABB HVAC drive, ACH580, meets the demand for uninterrupted performance required of mission-critical applications such as hospitals and data centres, while achieving the ambient comfort necessary for maximum productivity in commercial buildings, such as offices and schools.
In addition to offering energy savings up to 60 percent, the ACH580 offers an intuitive operating panel enabling quick and easy installation, and native BACnet (and Modbus) communications.
Smarter energy efficiency on show
The drive’s superior energy efficiency will be showcased at EMEX with an on-stand demonstration of an ACH580 drive and synchronous reluctance motor (SynRM) package.
ACH580 has the highest efficiency class for a drive and provides superior efficiency with all motor types, including induction, permanent magnet and SynRM motors. Energy savings are calculated internally and can be sent back to a building management system (BMS) via fieldbus. The drive also includes variable-speed internal fans, further saving energy.
However, it is when partnered with ABB’s IE4 SynRM motor that the ACH580 achieves energy savings of up to 60 percent, while delivering the best performance in the most efficient manner available on the market today.
Another exhibit demonstrates the cube law principles behind the VSD, namely, reducing motor speed by only 20 percent decreases energy consumption by up to 50 percent. A fan-based machine uses a balloon to demonstrate the potential energy savings of a VSD versus a conventional damper control system. The VSD controls the speed of an electric motor, which in turn drives a fan which pushes air through this duct. Within the duct is a mechanical damper, used to restrict air flow. Dampers are commonly used to control air flow in industrial applications. The demo shows that using VSDs not only saves up to 60 percent energy, but also incurs much less noise, than damper control.
The ACH580 features embedded HVAC communications capability, which allows users to control applications, report findings and perform diagnostics natively through BACnet MS/TP and HVAC protocols. BACnet IP over EtherNet can also be incorporated as an option.
ACH580’s intelligence and BACnet interoperability will be demonstrated by simulating the functions of a simple 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.
Speak to an expert
Experts from ABB’s energy team will be on stand offering advice on how they can optimise the energy efficiency and reliability of their HVAC applications with the latest VSDs, electric motors and life cycle services, including an ABB energy assessment.
On average, electric motors account for 65 percent of any facility’s electricity consumption. In just half a day, an ABB energy assessment will create an accurate picture of a facility’s motor-driven applications and identify where the greatest energy savings can be made. This information can then be used as part of an organisation’s ESOS assessment.
In addition, ABB’s John Guthrie talked aboiut the impact of VSDs on a diverse range of sectors, offering real-life energy saving examples from venues including hospitals and swimming pools through to water & wastewater during a seminar taking place in the EMEX’s Technology and Innovation Theatre.
