COMPACT Variable Frequency Drives

Buildings Consume Massive Amounts of Energy

• Commercial Buildings consume massive amounts of
  Energy
• Electricity 74 of the energy consumed by
  commercial buildings
• (source US DOE, 2008 Building Energy Data Book)
• Half of electricity consumed by buildings is used
  to move air
• More than half of the worlds energy is consumed
  by pumps and fans

An electric motor is a fixed-speed machine

VFDs Greatly Reduce Electricity Use

• (VFDs) significantly reduce electrical
  consumption
• Most pump and fan systems are oversized to
  account for maximum loads
• Capacity usually exceeds demand
• Application of VFDs converts systems to variable
  flow
• Green House Gas Reduction
• 80 of commercial building CO2 emission due to
  electricity consumption

VFDs provide the ability to vary the speed of a
motor

Why Do It? Less Energy Greater Savings

• Affinity laws Express relationship between
  rotational speed and flow, pressure and power
• Flow is directly proportional to speed
• Pressure is proportional to the square of speed
• Power is proportional to the cube of speed
