Baptist Hospital in Nashville, Tenn., is a 759-bed complex consisting of 13 buildings. Space cooling for nine of these is provided by seven electric hermetic centrifugal chillers. Located in three buildings--Central, Kidd, and Emergency (ER), which houses the newest chiller plant--these machines have a combined chilled water generation capacity of 5,800 tons. The five oldest units use CFC-11. HCFC-123 is the refrigerant used in the ER machines. In 1995, a new phase of chiller operation was initiated when the three plants were tied together to create a re-centralized central chilled water plant. This was done when the 1,300-ton chiller was added to the ER plant. The ER plant will ultimately replace the two older plants. Linking the three together was done to provide greater reliability and operating flexibility during the years that the ER plant is incrementally enlarged and the older Central and Kidd chillers are selectively retired.
