![]() Cooling Tower NameĪ unique descriptor for each cooling tower Under cooling conditions closer to design conditions, the CWS floats up to a maximum of 85 F (the design condition). ![]() The tower fan cycles to one-speed or off to maintain a CWS of 70 F at low wetbulb conditions. The baseline building cooling tower is assumed to have a two-speed fan that is controlled to provide a CWS of 70 F when weather permits. The baseline building pumping energy is assumed to be 19 W/gpm. ![]() The range between the condenser water return (CWR) and condenser water supply (CWS) is 10 F so the condenser water flow is a constant 2.5 gpm per cooling ton 1 Each baseline building chiller has its own condenser water pump that operates when the chiller is brought into service. The number of baseline building chillers is determined in 6.8.2. One tower is assumed to be matched to each baseline building chiller. Baseline building systems 7 and 8 have one or more cooling towers.
