NX Variable Frequency Drives Perfect match for HVAC Field Devices All you need in HVAC Control
Where are variable frequency drives used? • Buildings: • Primarily commercial • Applications: • Air handling • District Heating • Room & Zone • Operation: • Control fans, pumps, compressors to reduce energy consumption
Chiller Cooling tower Ventilation fan Boiler/heating pump Cooling coil Need for AC Drive! Heating coil Where are variable frequency drives used? • Heating, Ventilation and Air Conditioning (HVAC) system
What is a variable frequency drive? • Also known as: Frequency Converter (FC), Variable Speed Drive (VSD), AC Drive, Inverter etc. A squirrel cage motor is the typically used electrical motor in industry and public engineering sector Stepless control for the speed of a squirrel cage motor Cost reductions through Energy savings and improved quality Improved control over the system Smooth and Accurate control
Why use variable frequency drives? • Saves energy through fan and pump speed control • up to 70% energy savings in pump and fan applications • e.g. 32% average savings in a ventilation system → Payback period of 1 year • Decreases mechanical stress due to pressure spikes with direct on-line start & stop • VFDs creates a smooth start which reduces the pressure spikes that reduce system lifetime • Reduces the starting current of the motor • VFDs minimize the starting current of the motor, which means electrical installation investments can be lower Save energy, increase system lifetime, save on investments
