Simplified model for thermal comfort, IAQ and energy savings in rooms conditioned by displacement ventilation aided with transient personalized ventilation

The validated model was used to conduct a case study where comfort and air quality were assessed and the energy consumption of the transient PV + DV system was compared to steady PV + DV and standalone DV systems. It was found that the intermittent PV range [0.3-1 Hz] was able to improve comfort compared to steady PV and provide acceptable air quality. Moreover, energy analysis showed that the intermittent PV + DV (40 L/s) was able to achieve maximum energy savings of 54.61% and 31.58% compared to a standalone DV and steady PV respectively for equivalent comfort.
