Customer challenges
in HVAC systems

Harmonic currents are a significant challenge in modern data center cooling systems. Equipment such as modular chillers or air handling units (AHUs), which contain loads such as fans, compressors, and pumps, are operated with Variable Frequency Drives (VFDs). These VFDs have non-linear load characteristics, injecting harmonic currents that distort waveforms and degrade power quality.

Poor power quality leads to inefficiencies and potential damage to sensitive electrical equipment. Over time, this can cause increased system losses, reduced equipment lifespan, and operational downtime.

Additionally, regulatory requirements such as local grid codes and power quality standards such as IEEE519, G5/5, and EN 50160 mandate strict control of harmonic emissions. Non-compliance can lead to penalties, higher operating costs, and a failure to meet the environmental and efficiency goals of the project.

Understanding and addressing these challenges is critical for maintaining efficient, reliable, and compliant data center operations.
