What is VFD/VSD in Chillers: Efficiency Insights about?

This document discusses the benefits and limitations of variable frequency drives (VFDs) or variable speed drives (VSDs) for chillers. It explains that while VFDs help avoid surge issues at low loads and allow for starting, they consume slightly more energy at full load. The document recommends thorough system design over reliance on VFDs alone. It also notes that VFDs generate harmonics requiring filters and produce heat requiring cooling, impacting reliability. Overall system efficiency depends on factors
