Using a Constant Volume Displacement Ventilation System to Create a Micro Climate in a Large Airport Terminal in Bangkok
MetadataShow full item record
In order to conserve energy and create a comfortable climate for both passengers and workers at a new large international airport in Thailand, a design concept was created where only the first 2m above the occupied zone is conditioned. The temperature of the air outside of this area is allowed to rise above normal conditions. The idea was to let this temperature rise so that it was either equal to or higher than the outdoor temperature, thus reducing heat gain. Computer simulation programs were used to define parameters for the CF'D program. Once the boundary conditions were defined, the process of design analysis began. This paper will outline the steps taken to set up the CF'D program. Secondly, the exploration taken to obtain an optimal climate, and thirdly, how the many results were used to explain to both fellow engineers and the architects what had been achieved. The conclusion of this analysis was the design of special supply air grilles to meet the design criteria.
