Using ABB UK inverter drives in buildings for speed control of pumps, fans and compressors provides an effective way to improve air quality and optimise energy use.  The ABB ACH550-01 HVAC drives have ratings up to 160kW and provide users with ready-made macros for the most common HVAC applications such as pumps, fans and condensers.

In commercial and industrial buildings, an HVAC system maintains the desired air quality by controlling temperature, pressure, humidity, air change and carbon dioxide content. These properties are effectively controlled by an air handling unit (AHU).

Air Handling Units

The AHU’s supply and return air fans feed air into, and extract it from the building. Air quality is measured using appropriate sensors located within the air ducts throughout the building. Measurements from these sensors determine the required fresh air ?ow.

By running motors at reduced speed lowers energy usage and this precise control of air quality leads to a healthier and more comfortable environment.  It also allows for smoother control which reduces mechanical stress on pumps, fans and compressors, leading to reduced maintenance costs and lower noise levels.

Embedded within the ACH550 drives are PID control, native BACnet communication, timers, real-time clock and a calendar.  The BACnet ensures integration into all leading building management systems (BMS). Alternatively the drives can be used independently of a BMS system.

HVAC specific application macros

Fourteen HVAC specific application macros are pre-programmed and selectable without programming. The macros can be accessed via a detachable, intuitive control panel that is included with the ACH550 drive. The intelligence within the HVAC control panel means that the user is given direct and understandable instructions in clear text at all times.

The drive software also provides increased level of diagnostics and control for HVAC applications including easy commissioning and lower installation costs.
