Calculations of internal heat gain from occupants affecting the energy consumption of airport buildings

Abstract

In complex structures such as airports, when calculating metabolic heat gains from humans, convection and evaporation heat gains are taken into account, and then heat gains by convection, radiation, and evaporation from the skin surface are also taken into account. In the study, three different metabolic energy productions has been taken into account for a person sitting, standing or resting, doing light work and using a small hand tool. In the heat gain calculations from the skin surface, the lowest thermal resistance of the clothing was accepted. Based on the number of passengers, overall heat gain value calculated for one person was found for various airport buildings. As a result, the lowest overall heat gain has been calculated as 406.862 W for 0.2 m/s indoor air velocity and 70 W/m2 metabolic heat production, and the highest is 596.854 W for 5 m/s indoor air velocity and 115 W/m2 metabolic heat production.
