Zonal Guarantee Technology of indoor environment for the underground diesel generator plant, part I: Introduction

It is the premise for the diesel generator set to maintain the proper indoor environment of underground diesel generator plant. Based on the analysis and summarization of the characters of the heat and contaminant distribution in the underground generator plant, this paper proposes the ZGT (zonal guarantee technology) to remove the residual heat and contaminant with less energy. CFD software is adopted to do the numerical simulation for the two forms of the new technology. The results show that the novel technology, which can carry out the heat and contaminants simultaneously and effectively in general, may overcome the disadvantage of the ventilation and cooling schemes before.
