Particle Removal Efficiency in a Numerical Test Room
2003 (English)In: PROCEEDINGS OF THE 4TH INTERNATIONAL SYMPOSIUM ON HEATING, VENTILATING AND AIR CONDITIONING, VOLS 1 AND 2, 2003, 191-197 p.Conference paper (Refereed)
Particle removal efficiency in a ventilated room is investigated. This paper reports the differences in particle removal efficiency with various locations of supply and exhaust devices. Numerical simulations are carried out in a simple test room to illustrate the particle concentrations with different configurations of room ventilation. Several particle sizes are used and the influence of different flow patterns and air change rates are investigated. Particles are supplied to the room with the incoming air. Isothermal conditions with varying air supply velocities are used. Preliminary results indicate that particle removal efficiency is not predominantly influenced by air exchange rate, also the location of the supply/exhaust device is underestimated as an indicator of ventilation effectiveness.
