SIMULATION OF THE PERFORMANCE OF TRICKLE VENTILATORS

P. Karava, A. Athienitis, T. Stathopoulos

Abstract: This paper presents the results of a simulation study regarding the potential of trickle ventilator integration in ventilation design of office buildings. Design solutions for the opening area of trickle ventilators to satisfy the fresh air requirements, as recommended by ASHRAE Standard 62, are presented. The results are compared with the BRE recommendations. It was found that trickle ventilators should be used with fan assistance (hybrid ventilation) in stack-dominated office buildings to ensure that the required flow is delivered, especially at the upper floors. The required opening area varies with the height location of the trickle ventilator and the outside temperature. However, assuming typical Montreal design conditions and occupancy less than 12 m 2 per person, the study found that at least 5 cm 2 opening area per m 2 of floor area is required to ensure an acceptable comfort level for occupants.
