Energy efficiency in operating theatres: a case study

Summary form only given. The recent advances in air conditioning technologies and implementation had led to better performance, development and modifications to air flow pattern in air conditioned rooms. Design for ultimate comfort. Extensive efforts are exerted to adequately predict the air velocity and turbulence intensity distributions in the room and to reduce the energy requirements and noise abatement to ultimately produce quite and energy efficient air conditioning systems. The present work summarizes the Egyptian activities in manufacturing, installation, education, research & development. Computational methods can adequately predict flow patterns and regimes in air conditioned rooms at different operating conditions, identified high turbulence levels appears in the roof zone. The present modeling capabilities can adequately predict the local flow pattern in air conditioned spaces. Predictions demonstrate flow patterns that are similar in form but differ in details at different operating conditions. Prediction capabilities were extended to include local dry bulb temperature distributions, turbulence intensities and relative humidity contours. The present program accounts for the thermal loads of the room, humans, equipment and supply air. Turbulence characteristics as identified here by the shear stresses indicate that higher turbulence level appears in the roof zone.
