Variable-Speed Direct-Drive Screw Chiller
Green Proving Ground (GPG) evaluated a variable-speed direct-drive screw (VSS) chiller against a baseline state-of-the-art chiller technology, the variable-speed magnetic bearing chiller (MBC). Results showed similar performance for both chillers.
Agencies should consider both VSS and MBC for new or end-of-life chiller replacements. Individual site characteristics will determine the most cost-effective chiller technology for a particular application. View full-size infographic. [PDF - 455 KB]
