Abstract
A displacement ventilation system exploits the use of energy efficiently because it is possible to remove exhaust air from a room with a temperature that is several degrees above the temperature in the occupied zone. This process will allow a higher air inlet temperature at the same load in comparison with mixing ventilation.
It is necessary to have a design method for the temperature distribution used for instance in connection with the tlow element method and the energy calculations. The temperature distribution is also important in connection with thermal comfort in a room. It is necessary to consider the temperature gradient in the occupied zone, as well as the asymmetric radiation from the ceiling, in connection with the design of a displacement ventilation system and the evaluation of thermal comfort.
This paper will introduce five temperature distribution models with different levels of complexity.
