Decreasing the air flow, reduces the energy used to heat or cool the fresh air, resulting in further savings. Several features of the Danfoss dedicated adjustable frequency drive can be used to improve the performance of a 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 30: Cooling Tower Fan
The adjustable frequency drives can also be used to turn the fan on and off as needed. With the Danfoss HVAC adjustable frequency drive, as the cooling tower fans drop below a certain speed, the cooling effect decreases. When using a gear box to frequency control the tower fan, a minimum speed of 40–50% could be required.
