Cross-infection risk

This study aims to evaluate airborne cross-infection risk under different discharge angle (-20°, 0°, and +20°) and supply temperatures (18, 25, and 30 °C) of an air-conditioner, with various body orientations (face-to-face, side-by-side, and back-to-back). Field experiments on particle dispersion were conducted within a full-scale test chamber using a manikin-shaped particle generator and detector with simulated particles (NaCl). Initial trends in particle transmission varied with body orientations.
