Abstract  Introduce the principles of using Variable Speed Drive (VSD) technology in centrifugal chiller and its
energy saving mechanism is analyzed as well. Its impact on Part-Load Value (IPLV/NPLV), Coefficient of Performance
(COP) and compressor efficiency under different load are analyzed after test. This provides a guide to adopt this
technology effectively in actual projects.
