Impacts of Optimized Cold & Hot Deck Reset Schedules on Dual Duct VAV Systems - Application and Results
Abstract
In the theory and modeling part, the
principles of VAV box optimization are
investigated. The simulations show that
optimizing cold and hot deck reset schedules can
significantly reduce the amount of energy
consumption.
During a Continuous Commissioning (CC)
process, the optimal cold and hot deck reset
schedules were implemented in 12 dual duct
variable air volume systems which serve a
324,000 ft2 university building. The improved
cold and hot deck reset schedules combined with
other CC measures reduced the chilled water
energy consumption by 7,571 MMBtu/yr (18%)
and 303 MWh/yr (18%) for the fan power. The
estimated heating energy savings are 2,327
MMBtu/yr. The estimated annual cost savings
are $75,040/yr. This paper presents the building
and AHU system information, optimal reset
schedule, and measured results.
