Impacts of Optimized Cold & Hot Deck Reset Schedules on Dual Duct VAV Systems - Theory and Model Simulation
MetadataShow full item record
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.
