Résumé

For multi-zone variable air volume (VAV) air-conditioning systems, presents an adaptive demand-controlled ventilation strategy with temperature resetting in critical zones to meet the indoor air quality demand of each zone with minimum energy consumption. This strategy in a real-time way detects personal load of each zone, identifies the critical zones online, and fully considers the outdoor air demand of the criteria zones and the unviviated outdoor air in the re-circulated air from other zones. The air temperature resetting in critical zones results in the increase of the supply air fraction and therefore the amount of outdoor air delivered to the critical zones. Consequently the total outdoor air demand and the overall energy consumption are reduced while the ventilation, of critical zones is satisfied. This strategy and the control algorithm are validated in a "living" environment of dynamic simulation platform of multi-zone VAV air-conditioning systems in term of dynamic control performance, energy performance and environmental performance by comparing with alternative demand-controlled ventilation strategies.
