One of the benefits of using ABB standard drives for HVAC in pump and fan applications, is the energy saving opportunity over other control methods that are used in combination with motors running at fixed speeds. Rather than have an electric motor running continuously at full speed, an AC drive allows the user to variably control the motor speed, depending on the demand.
A guide to using variable-speed drives and motors in data centres
Data centres require massive amounts of power to keep them running smoothly and efficiently. Most of this power consumption is used by the IT load, 40 percent, with the cooling system requiring 35 percent. So if the HVAC systems can be made to work more efficiently, huge sums of money can be saved.
