The HVAC&R industry is trending towards variable speed technology such as electronically commutated motors (ECMs), variable frequency drives (VFD) motor solutions, variable speed compressors, chillers, pumps, fans, and variable refrigerant flow systems (VRF). Building owners and engineers are requesting HVAC&R equipment to comply with IEEE 519. The goal of this program is to help our participants avoid harmonics overfiltering and underfiltering. Both excessive and minimal harmonic filtration scenarios can cause issues with electrical and HVAC&R equipment. With industry demands of high energy standards (Title 24, ASHRAE 90.1, IECC), harmonics has emerged as an increasingly critical topic in the building industry.
