Energy-efficient variable-air-volume (VAV) system with zonal ventilation control. ScholarBank@NUS Repository. | Abstract: | A ventilation and air-conditioning system uses a first variable-air-volume system to cool and dehumidify fresh outside air and deliver it through a first duct to a mixing box located downstream. The system also uses a second variable-air-volume system to further cool and dehumidify recycled air and deliver it through a second duct to the mixing box where the fresh and recycled air are able to mix prior to ventilation into a room or office. The system uses a carbon dioxide sensor and a temperature sensor to provide feedback signals to a control system, which in turn regulates fan speeds and damper openings in order to provide optimal cooling and ventilation and to conserve energy when cooling and ventilation requirements are low. | URI: | http://scholarbank.nus.edu.sg/handle/10635/32666 |
