WebIn this case, the chiller temperature range is 8°F while the cooling coil range is 10°F . The overall result is increased chilled water pump and pipe capital cost plus higher annual pumping cost. Basic Components Parallel chillers experience the same percent load. Webchillers are set up in a “parallel” scheme where each chiller is equally sized. This would require the chillers to provide an identical chilled water set point and a dedicated cooling …
WebA key issue with parallel chillers is plant operation at light loads. In particular, there is no easy way to operate just one chiller in a constant flow system. Turning off one of the chillers allows return water to flow through it without any change in temperature. This un-cooled water mixes with the cooled water from the other chiller(s ...
