2001 ASHRAE Technology Awards: Innovative Chiller loading Strategy PDF

Spectrum Health's Blodgett Campus facility in Grand Rapids, Mich. has expanded to 416,000 net ft2 (38 600 m2), which includes operating rooms, an emergency department, labs, patient rooms and a medical office building. The facility's continued growth and its increase of internal equipment loads created a need for more cooling capacity. The facility's cooling requirements on summer days with high wet-bulb temperatures exceeded the central chilled water plant's capacity.
