【摘要】 室内氡(含氡子体)污染的传播与粒子(悬浮颗粒)污染在室内的传播过程相关,通风空调气流对氡及粒子污染的传播影响很大。本文详细阐述了室内氡和粒子的来源和特点、氡及其子体在空气中的传播机理以及除去方法,分析了通风空调系统对室内氡及子体传输的影响、以及氡在空气中迁移的动力学模型,分析比较了通风室内氡及粒子污染物迁移沉降过程的数值模拟方法,提出了空调气流环境下氡及粒子污染传播及其数值模拟中的关键问题。更多还原

【Abstract】 The indoor diffusion process of radon is related to pollution of particles(aerosol).The airflow of air conditioning makes a great influence on the radon and particles.In this paper,the sources and characteristics of the indoor radon pollution and particles,the spread mechanism and the way to eliminate radon and its daughter are described.The effect of the ventilating air conditioning system to the transmission of indoor radon and radon dOcthter,the dynamics model of radon transfer in the air are analyzed.The numerical simulation method of radon and particle pollution process in ventilation room are compared and analyzed.The key problem of radon and particles pollution and numerical simulation under air conditioning environment are brought forward.更多还原
