Adaptive and distributed operation of HVAC systems: Energy and comfort implications of active diffusers as new adaptation capacities

摘要: Abstract Human-aware HAVC operations have been shown to be effective in improving energy efficiency, which is constrained by the HVAC system configuration and operational logic. These constraints can result a lack of flexibility, turn reduces adaptation capacity for efficiency. Therefore, this study, we investigated efficiency implications novel adaptive capacities including use proposed active diffusers, add dynamics systems adjusting behavior diffusers using two modalities (1) binary actuation air flow (turning on off), (2) direction target individual needs an environment. Computational fluid was used model simulate “real-world” thermal zone evaluate five scenarios distributed feedback from environment, as well diffusers. Three at (collection rooms) level, examined level. Moreover, integration occupant locations into control loop averaged temperatures (in first three scenarios) individual-level with diffuser level actuation). The coupling independent directional considerably improved comfort while reducing demands ~25%—reflecting considerable impact findings demonstrate potentials that artificial intelligence frameworks could bring about enabling autonomous operations.
