  • Page 15 3.1.1.3 Comparison of Energy Savings The Danfoss drive solution offers major savings compared with traditional energy saving solutions such as discharge damper solu- tion and inlet guide vanes (IGV) solution. This is because the drive is able to control fan speed according to thermal load on the system, and the drive has a built-in facility that enables the drive to function as a building management system, BMS.
  • Page 16 Illustration 5: Energy Savings Discharge dampers reduce power consumption. Inlet guide vanes offer a 40% reduction, but are expensive to install. The Danfoss drive solution reduces energy consumption with more than 50% and is easy to install. It also reduces noise, mechanical stress, and wear-and-tear, and extends the life span of the entire application.

  • Page 20 Centrifugal devices such as fans behave according to the centrifugal laws. This means that the fans decrease the pressure and flow they produce as their speed is reduced. Their power consumption is thereby significantly reduced. The PI controller of the drive can be used to eliminate the need for additional controllers. 20 | Danfoss A/S © 2021.04 AJ363928382091en-000101 / 130R0983...
  • Page 21 Several features of the Danfoss dedicated drive can be utilized to improve the performance of the CAV system. One concern of controlling a ventilation system is poor air quality. The programmable minimum frequency can be set to maintain a minimum amount of supply air regardless of the feedback or reference signal.
  • Page 22 Several features of the Danfoss dedicated drive can be utilized to improve the performance of cooling tower fans applications. As the cooling tower fans drop below a certain speed, the effect the fan has on cooling the water becomes small. Also, when utilizing a gearbox to frequency control the tower fan, a minimum speed of 40–50% is required.
  • Page 23 Using a drive instead of a throttling valve simply saves the energy that would have been absorbed by the valve. This can amount to savings of 15–20% or more. Trimming the pump impeller is irreversible, thus if the conditions change and higher flow is required the impeller must be replaced. Danfoss A/S © 2021.04 AJ363928382091en-000101 / 130R0983 | 23...

If optimum EMC performance is needed, or parallel motors are connected, or the motor cable length is above 25 m (82 ft), Danfoss recommends setting parameter 14-50 RFI Filter to [On]. It is important to use isolation monitors that are rated for use together with power electronics (IEC 61557-8).
