What determines chiller plant loading? Do connected plants need to use similar pumping schemes? Is it better to run one chiller in multiple plants or multiple chillers in one plant? Draw on the author’s experience for answers. Then learn how to handle the hydraulics of interconnection and enjoy the byproducts of a well-integrated system.
