摘要
以电力电缆舱室为例,通过软件模拟800 m通风区间长度下舱室内的气流组织分布,研究城市综合管廊长大通风区间的气流特性以及适宜节能的通风方案。针对实际综合管廊风机运行,试验测试了不同通风形式下的风量及风压,与模拟结果对比分析,验证了模拟的可靠性。分析了通风形式与通风区间长度之间的关系,提出了当通风区间长度小于600 m时,可采用自然进、机械排的通风方式,采用机械进、排时,通风区间长度为800 m时风机较节能。
Taking the power cable compartment as an example, the airflow organization in the compartment is simulated by software for a length of 800 m ventilation compartment to study the airflow characteristics of the grown-up ventilation compartment of the urban integrated corridor and the suitable and energy-saving ventilation solution. In view of the actual operation of the integrated pipe gallery fan, the air volume and pressure under different ventilation forms were tested and compared with the simulation results to verify the reliability of the simulation. The relationship between the ventilation form and the length of the ventilation interval is analyzed. It is proposed that when the length of the ventilation interval is less than 600 m, natural ventilation and mechanical ventilation can be adopted. When the length of the ventilation interval is 800 m, the fan can save energy.
