Enjoy substantial energy savings in HVAC fan and pump applications by simply using AC drives in place of dampers, valves and vanes. How do AC drives save energy? These are controls for the AC motor, and can help tremendously with energy savings if the output required in the application is less than nominal most of the time.
AC drives are used to control the fan and pump speed by changing the supply of electrical energy instead of damping the air or water flow. The process works similar to reducing pressure on a car accelerator instead of pressing the brake. HVAC applications that use AC drives for fans and pumps typically bring a payback within one year or less.
There are multiple benefits to using AC drives for HVAC fans and pumps. One is the reduction of noise levels, which is achieved by slowing the speed instead of damping the output. Another benefit is that a smooth ramp up and down causes less strain on the mechanical parts of fans and pumps as well as the water pipes and air ducts. It’s also easier to tune the HVAC system during and after commissioning due to the flexibility of AC drives.
A Measurable Difference
More good news…you don’t have to guess whether or not your AC drives are indeed saving energy and money. Some AC drive manufacturers provide software that estimates the energy savings for fan and pump applications, compares AC drive usage with conventional motor control methods, and provides payback data. This enables your company to easily calculate and analyze savings. Energy savings equals dollar savings, and HVAC systems typically account for a large percentage of energy usage in any home or facility. So consider using AC drives to control each HVAC fan and pump, and notice how these save your facility dollars in energy costs year after year!
