Abstract

Computational fluid dynamics simulation of an apartment underground elevator hall has been carried out to study the effect of dehumidifier locations on condensation problem. In Case 1, horizontal position of humidifier is studied. It is installed at entrance, center or the inside of the elevator hall. In Case 2, installation height is studied, one at 0 m and the other at 1.6 m above the floor. In Case 3, exposed and embedded dehumidifiers are compared for performance. The study shows that the entrance, top and exposed locations are more effective in reducing condensation.
