水电站地下厂房通风空调模型试验主要问题及处理方法

The Main Problems and Treatment Methods of Hydropower Station's Underground Powerhouse Ventilation and Air Conditioning Model Test

目前,相似模型试验研究是水电站地下厂房热湿环境分析以及通风空调气流组织研究最可靠的方法。水电站通风空调模型试验通常按照阿基米德相似准则,建立缩小尺寸的模型试验台,进行相似模型试验研究。模型试验中,由于部分参数比例尺比较小,导致这些参数量值非常小,给模型试验带来了许多问题。根据多个水电站通风空调模型试验的研究结果并结合某大型水电站地下厂房通风空调模型试验的实践经验,从围护结构传热、气流组织方式的模拟、通风管路的传热以及内部发热设备的制作与控制等方面分析了水电站地下厂房通风空调模型试验中存在的主要问题,根据试验结果提出了解决这些问题的技术措施。

At present, the similar model test is the main method which is used in research of hot and wet environment analysis and ventilation and air conditioning air flow organization of the hydropower station＇s underground powerhouse. The ventilation and air conditioning model test of the hydropower station is usually according to the Archimedes. The geometry size of the hydropower station model is usually very small to the real size. The value of paramerers in the hrdropower station model is very small. So it takes many problems to the model test. Based on a ventilation and air conditioning model test of a large scale underground hydropower station, an analysis of some main problems of the ventilation and air conditioning model test of the underground hydropower station was made and some technical means to solve these prolems were put forward in the paper.
