VFD Application Engineering
VFD for HVAC
How VFDs improve HVAC fan and pump control, energy efficiency and system stability.
Why use a VFD in HVAC?
A VFD adjusts motor speed to match real airflow or water-flow demand.
Motor Speed Control
Speed control can reduce energy use significantly in variable-torque loads.
Torque and Current Considerations
Check motor current, overload duty, ambient temperature and acceleration requirements.
VFD Selection
Select voltage class, current rating, EMC needs and enclosure protection.
PLC Integration
VFDs can integrate using digital I/O, analog signals or industrial communication.
Technical Checklist
