2nd Quarter 2009Electrical switching & drive systems & components
Motor and drive supplier ABB claims that a new fan system powered and controlled by its energy-efficient motors and drives has reduced the annual energy bill of a Swedish hospital by R4m ($400 000) and reduced fan maintenance requirements by 90%.
By replacing an ageing and inefficient fan system with 30 new fans powered and controlled by ABB high-efficiency EFF1 motors and ACH550 standard drives, the hospital reduced the load drawn by each fan by almost 30%, from 65,2 kW to 46,4 kW.
“The reduced energy consumption of one fan equates to a saving of $13 100 a year at today’s prices,” says Bengt Jönsson, chief engineer for the real estate management unit of the regional health administration. “This is a massive saving. Multiplied by 30 fans it works out at a total annual reduction in energy costs of about $400 000.”
Maintenance requirements have also been dramatically reduced.
ABB EFF1 motors are rated in the highest efficiency category for motors sold in Europe. They yield high energy savings, are exceptionally reliable, waste less energy as heat, and operate at a much lower temperature at full load than low-efficiency models.
The award-winning ACH550 standard drive is the first dedicated ABB AC drive for heating, ventilation and airconditioning (HVAC) applications and the manufacturer claims that it is currently the only drive on the market to meet the new European standard for electromagnetic compatibility and limited harmonics.
More than 300 000 ACH550 HVAC drives have been sold worldwide.
