Best practice examples of reduced power consumption in building services and refrigeration by integrated control of EC fans and motors.

Author(s) : BRADWELL S.

Summary

It is shown that the power consumption of building services and refrigeration can run to over 50% of total power consumption with buildings. Of this, a significant proportion is fan and motor applications in HVACR. This review will detail some examples of best practice solutions in the application of high efficiency EC fan technology and the benefits of speed control in achieving reduced power consumption and hence carbon emissions. Examples of integrated fan solutions show power and carbon footprint savings are shown. Those discussed include: 55% fan power savings in air handling units; 61 000 Mtonnes C02 savings in condensers; Constant pressure and constant volume ventilation control systems; 38 000 tonnes CO2 in refrigeration.
