Central Chilled Water SystemVWS Design Basis
– Containment Isolation: Safety-related, seismic, ASME III, 1E– Provides 40°F chilled water – VWS air-cooled chillers shall be designed for operation using
outdoor air with a maximum summer design temperature of 115°F dry bulb / 85.5°F wet bulb and a minimum winter design temperature of -40°F based on 0% exceedance
– VWS water-cooled chillers are designed for stable operation using Component Cooling Water System (CCS) water with a temperature range of 60 to 95°F.
