孔板送风气流组织形式在电厂空调系统中的适用性分析

Discussion on application of perforated ceiling air supply to air conditioning system of fossil-fuel power plant

结合大中型火力发电厂集中空调系统设计,发现传统的气流组织方式并不是满足工艺设备温湿度要求和人员舒适性的最佳气流组织方式。从室内环境温湿度、洁净度、人员舒适性、室内装饰装修、电缆走线等方面研究了在电厂集控室、电子设备间等采用孔板上送下回方式的可行性。结合某实际工程案例进行孔板送风的室内布置,采用Airpak软件对该案例室内环境进行了数值模拟,直观表征了室内温度场和流场等。

Combined with central air conditioning system design of large and middle scales of fossil- fuel power plants, finds that the traditional air distribution is not the best way to meet the requirements of temperature and humidity of process equipment and occupants＇ comfort. Studies and discusses the feasibility of perforated ceiling air supply system application to control room and electronic equipment room from indoor temperature, humidity, cleanliness, comfort, interior decoration and cable routing. Taking a project as an example, adopts perforated ceiling air supply system and simulates the indoor environment using Airpak software to represent the indoor temperature and flow field visually.
