Specific application considerations for PDF 9.2.8 Safety Chilled Water System 9.2.8.1 Design Bases SCWS flow diagram is shown in Figure 9.2.8-1—Safety Chilled Water System Diagram. Pipe diameters for the SCWS are based on limiting the flow velocity to a range of 4 to 10 ft/second for normal modes of operation that are expected to occur frequently. Refer to Section 12.3.6.5.9 for safety chilled water system design features which How a Chiller, Cooling Tower and Air Handling Unit work ... The chilled water enters the AHU/FCU and passes through the cooling coil (a series of thin pipes) where it will absorb the heat of the air blowing across. The chilled water heats up and the air blowing across it cools down. When the chilled water leaves the cooling coil it will now be warmer at around 12°C (53.6°F). Control sequences for chilled water systems - Consulting As the chilled water valve begins to open, the chilled water differential pressure transmitter senses a drop in system pressure. This sends a signal to the chilled water control panel and VFDs. The pumps are designed to operate in a parallel configuration. Currently a single pump is operating in response to water flow requirements.
