Underfloor air distribution system; Pressurized plenum; Zero-pressure plenum
한국생활환경학회지, v. 14, No. 4, Page. 343 - 350
The purpose of this study is to analyze the performance of hybrid underfloor air distribution system. The characteristics of the several types of underfloor air distribution system were explicated. The computer simulation and the field and laboratories experiment were conducted. As the results, the pressure of plenum became decreased according to the increase of volume flow of FTU with hybrid underfloor air distribution system, but the pressure difference was not changed. The pressure difference was increased in proportion to the volume flow of AHU. It is necessary to consider the proper strategies when the plenum has the longer supply distance and/or the high pressure of the lower part.
