气溶胶粒子在风管中沉积特性的研究进展

Progress in Study on the Aerosol Particles Deposition in Ventilation Ducts

残留在空调通风管道中的气溶胶粒子被气流带入房间会降低室内空气品质,影响人体健康。为了改善空调通风系统的卫生状况,国内外的许多学者分别采用物理实验、经验公式、数值模拟等方法研究了气溶胶粒子在管道中的沉积规律,本文详细综述了这部分内容,并对三种方法作出了比较。最后指出今后该领域的研究和发展方向。

The aerosol particles deposited onto duct surfaces will be taken into rooms by supply air, which would pollute the indoor environment and cause adverse effects on human health. Many authors investigate particle deposition in ducts by means of Physical Experiment, Empiricism and Numerical Simulation. These contents are summarized and above three methods are compared in this paper. At last it also indicates the subse- quent study and development orientation in this field.
