G126.96.36.199 Type and Number of Chillers (Systems 7, 8,11,12, and 13)
Electric chillers shall be used in the baseline building design regardless of the cooling energy source, e.g. direct-fired absorption or absorption from purchased steam. The baseline building design's chiller plant shall be modeled with chillers having the number and type as indicated in Table G188.8.131.52 as a function of building peak cooling load.
Table G184.108.40.206 Type and Number of Chillers
|Building Peak Cooling Load||Number and Type of Chillers|
|≤300 tons||1 water-cooled screw chiller|
|>300 tons, <600 tons||2 water-cooled screw chillers sized equally|
|≥600 tons||2 water-cooled centrifugal chillers minimum with chillers added so that no chiller is larger than 800 tons, all sized equally|
