Impacts of Optimized Cold & Hot Deck Reset Schedules on Dual Duct VAV Systems - Theory and Model Simulation
Abstract
Optimal hot and cold deck reset schedules
can decrease simultaneous heating and cooling
in VAV AHUs comparing with constant cold
deck temperature operation. In this paper,
optimization models are developed. The energy
impacts are simulated for a typical office
building in the hot and humid climate
(Galveston, Texas).
The simulation results show that the
optimized reset schedules can reduce the cost of
AHU energy consumption (cooling, heating and
fan power) by 8% to 20% in normal VAV
systems when the minimum air flow rate
increased from 30% to 70% of the maximum
flow.
