HVAC
Heating, Ventilation, and Air Conditioning (HVAC) systems rely heavily on electrical components for controlling compressors, fans, pumps, damper actuators, and heating elements. Industrial and commercial HVAC applications use contactors for compressor and fan motor switching, VFDs for energy-efficient fan and pump speed control, sensors for temperature and pressure monitoring, and PLCs or dedicated HVAC controllers for system coordination. Proper selection of electrical components directly impacts HVAC system reliability, energy efficiency, and indoor air quality.
