不同通风方式下室内甲醛净化效果的数值模拟
Numerical simulation of indoor formaldehyde purification under different ventilation modes
摘要
Abstract
This paper is focused on the efforts to obtain reasonable indoor formaldehyde removal methods by simulating the concentration and velocity field distribution of indoor formaldehyde under three conditions of airtight, natural ventilation and mechanical ventilation using Flent 14. 5 software. The result shows that there is a better coupling both in the velocity field and concentration field under the same working condition;natural ventilation or forced air intake produces an obvious vortex near the two sides of the window, but this is not the case with the forced exhaust; the use of mechanical ventilation gives forced ventilation an advantage over forced air supply, as in the case of limited ventilation;the sufficient ventilation volume ensures the adequate performance of both, with an emphasis on the purification near pollution sources in the case of the forced exhaust and more attentions on vortex in the case of the forced air intake. The study may provide a useful reference for indoor formaldehyde treatment.关键词
