摘要

摘要:针对我国集约化养鸡场存在的氨气浓度高、气流组织不佳的问题，根据有限体积法，建立了某一智能鸡舍诱导通风系统的数学模型和物理模型，设置相应的边界条件，采用Airpak软件进行数值模拟，分析了诱导风机的布置参数及鸡舍中空气流动速度、温度以及氨气浓度等因素，研究结果表明，鸡舍中诱导风机的下倾角为15°，纵向间距为12m，横向间距为7~7.5m时，采用诱导通风方式能有效解决鸡舍内温度过高与氨气浓度过高的问题，达到良好的通风效果，对改善鸡舍环境品质有显著作用。

Abstract

Abstract:Aiming at the problem of the high concentration ofharmful gases and poor air distribution in an intelligent control broiler housein China

the mathematical and physical models of induced ventilation systemwere established.According to the finite volume method

the corresponding boundary conditionswere set up.Numerical simulation has been done by Airpak. It is analyzed how to set theparameter of induced fan and factors in broiler house

including the velocity

temperature

and ammonia concentration. The results prove that the induced ventilation method caneffectively solve the problem of high temperature and ammonia concentration inbroiler house

achieve the better ventilation effect

and improve theenvironment quality in broiler house when the induced fan is set at 15° of thedeclination

and 12m of the appropriate longitudinal spacing

and the horizontalspacing from 7m to 7.5m.
