Customer challenges
in HVAC systems

Heating, ventilation, and air conditioning systems (HVAC) are vital parts of modern buildings for optimum indoor environmental comfort levels. The key components of HVAC systems are chillers, cooling compressors, water pumps, and fans which are typically run by variable frequency drives (VFDs). Even though variable frequency drives help meet increasingly demanding efficiency requirements, they are typically known to be the main source of power quality issues like harmonic currents.

Poor power quality affects energy efficiency and can also result in potential disturbances to the electrical system. A network with high levels of harmonics can experience a wide range of costly issues. Overheating can cause sensitive and critical electrical components to break down prematurely and reduce the lifespan of all devices and equipment. In addition, high harmonic currents can also jeopardize the reliability of operations in critical facilities like data centers.

Applications like chillers, fans compressors, and pumps are fed with Variable Frequency Drives (VFD), etc.
