Emissions of underground diesel engines are facing more and more stringent control because of their adverse effects on human body. The novel zonal guarantee technology presented in this paper will remove the heat and contaminant simultaneously and effectively. The technology divides the space into the stronger load zone and the weaker load zone. For different zone, ventilation and cooling system uses...
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 merits and drawbacks for the diesel generator set heat exchange modes and ventilation and cooling schemes of underground diesel generator plant, this paper proposes a novel ventilation and cooling scheme for water cooling and...
In this paper the ZGT (zonal guarantee technology), which has been introduced in the companion paper, is applied to the deep-buried underground engineering. Then, four novel ventilation and cooling systems for the underground diesel generator plant are presented. The optimization of the location of the fume exactor and exhaust duct and the speed of the supply air is done by the CFD simulation for...
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...
