【摘要】 有效地通风和合理的气流组织对于改善室内空气品质,控制室内污染物浓度,对实现健康建筑、舒适性空调有着重要的意义。室内空调气流组织方式多种多样,对其效果的研究也很多,但是多集中在理论分析,而对气流组织效果的监测方面的研究较少,且监测方法没有一个完成的体系。首先对空调气流组织现场监测和评价方法进行分析,得知现场检测方法多以工程标准,只是对室内气流组织的应用效果进行评价,并不能完全反映气流组织的轨迹特征。其次,为了更好的反映不同时刻空调气流组织的特征,建立气流组织的监测方法,以5m×3m×2.8m的一个典型实验房间为例,利用计算模拟方法,分析不同气流组织形式下温度、风速等衰减特征,为室内气流组织现场智能监测测点布置提供依据。更多还原

【Abstract】 Indoor air quality can be improved through effective ventilation and reasonable air distribution, and indoor pollutant concentration controlled has a great significance for realizing healthy building and comfortable air conditioning. Indoor air organization form is diverse, and each form has its own characteristics. For the air distribution, many research focus on the theoretical analysis, few study on the actual effect of air conditioning monitoring, and there is no complete system for intelligent monitoring. In this paper, field monitoring and evaluation methods are analyzed firstly, and the field test method is mostly engineering standard, it is not possible to evaluate the inhomogeneity of indoor temperature distribution. Based on the experimental study of air distribution, the design of intelligent monitoring system for air distribution in air conditioning building is studied. A 5 m x 3 m x 2.8 m typical room is built, the characteristics of different air distribution patterns were simulated in software, and the temperature, wind speed are analyzed dynamically. The measurement points of different environmental parameters are arranged according to the air flow characteristics, and the field test results used to verify. Compare with the existing field monitoring standard method to perfect the intelligent monitoring design method. This study provides a basis for the monitoring design of indoor air flow.更多还原
