Variable Speed Drives for Fans and Pumps are an approved Green Deal measure under the Building Service Electrical category.
What are Variable Speed Drives for Fans and Pumps?
Variable Speed Drives are a good way to save large amounts of energy. By dropping the speed of centrifugal pumps and fans by 20% this could save as much as 50% in energy.
Although peak demand may only be needed for a few hours, many heating, cooling and ventilation systems operate at a constant flow rate. By doing it this way, a lot of energy is used and the life span of the equipment is shortened. It is much more efficient to use variable speed drives, therefore varying the air or water flow to meet the changing load demands more precisely.
Variable speed drives have been designed for optimum energy efficiency.
