they may consider increasing the chilled water temperature differential at the
allows for the removal of glycol from the plant side which reduces the overall
performance and control. This would require that all buildings be decoupled
the campus. Once Facilities Management has achieved plant optimization,
wild” due to the lack of a building control valve. Decoupling the plants also
to increase the capacity of their plants. For this report, however, all values
and be able to utilize their cooling capacity to support the future growth of
uid flow and pumping needs at the plant by approximately 5 percent and
an associated control valve. There are existing buildings that are “running
plants and respective buildings to a 13ºF temperature differential in order
from their respective chiller plants through a building heat exchanger and
improves heat transfer. In doing this, the plants will operate as designed
The goal for the existing chilled water plants is to optimize each plant’s
and scenarios are based on a 10ºF temperature differential and 20 percent In addition to reviewing the capacity of the plants, the distribution piping has been reviewed. In general, it is good engineering practice to limit chilled water piping velocities to 10 feet per second (FPS) or 5 feet of loss per 100 feet of pipe (FT/100 FT), whichever is the more restrictive factor.
