The impacts of the water loop management
on the heating and cooling energy consumption
are investigated by using model simulation. The
simulation results show that the total thermal
energy consumption can be increased by 24%
for a typical AHU in San Antonio, Texas when
the differential pressure is increased from 7 psi
to 21 psi for both chilled water and hot water
loops. It appears that significant amounts of
energy consumption can be reduced by
improving the differential pressure of water
loops. This paper presents the system model,
methods, and the results
