Stimulation Study over the Capacity of Air Distribution to Eliminate the Contaminant in Isolation Wards
The isolation wards should use the reasonable air distribution to control the distribution and elimination speed of the contaminant. This paper will simulate the distribution of the carrier particles in the wards under the condition of different ventilation rates and air distribution and the change rules of the remaining particles with the time by building a ward model with unsteady stated contaminant source. The simulation results show that all the factors like the arrangement of the air inlets, the ventilation rates, the amounts of the air outlets could affect the capacity of the air distribution to eliminate contaminants, among which the effect of the ventilation rates is the most remarkable. The conclusion also proves that using the CFD technology to simulate could have great guiding significance on determining the various form factors of the air distributions in the wards.
