Exhaled contaminant concentration data in a hospital room influenced by external heat gains.

ABSTRACT: A hospital room is simulated using two breathing thermal manikins representing a health worker (HW) and a patient in repose (PR). The PR exhales R134a simulating small exhaled particles (<5 μm) and the contaminant concentration around and in the inhalation of HW is measured during a period of 2 hours per experiment. The room is climatized to maintain constant air temperature values of 25 °C using two wall mounted grilles and two exhausts. The air change per hour (ACH) used varies from 6 to 12 in order to evaluate its influence on the dispersion of exhaled contaminants. An external heat gain is simulated by a radiant wall (RW) that is active or inactive during the experiments. When RW is active the external heat gain simulated is 39.7 W/m², which corresponds to a solar external r
