Original Abstract
This study investigated the interaction of the thermal plumes (TP) of the patient´s wound with two different room temperatures, 21°C and 23°C in two operating rooms with mixing (MV) and laminar airflow (LAF)at St. Olav’s hospital. The indoor environment parameters such as temperature, air velocity, and turbulence intensity were measured for the investigation of the thermal plume (TP) over the patient’s wound with an interrogation area of 100 cm (height) × 60 cm (width). The higher turbulence intensity appeared along the vertical direction with mixing ventilation. In the case of laminar airflow, the high turbulence intensity zone is located in the horizontal direction around the patient’s wound which indicates suppression of the buoyancy effect by the downward laminar airflow.
