沙漠地区高压变频室采暖通风与空气调节设计探讨

Discussion on the design of heating,ventilation and air conditioning in high pressure frequency conversion chamber in desert area

国内大部分项目中均有设计高压变频室的室内通风,常采用的方法是"通风次数法"或"热平衡法"计算风量,此种计算方法简单,可完全满足室内设备运行环境温度及风量要求,适用于电负荷较小、通风量小的项目上。针对于沙漠地区天然气处理站缺水、缺电、室外沙尘天气较多,高压变频室电负荷大,通风量大的情况,研究如何设计才能保证高压变频室正常供电要求显得尤为重要,通过对国内几种大型项目高压变频室的设计方案进行探讨,选择适合沙漠地区变配电间的设计思路。

Indoor ventilation design for high voltage frequency conversion room in China,The usual methods are"ventilation times"or"heat balance"calculated air volume,It is considered that the design can fully meet the requirements of indoor equipment operating environment temperature and air volume,This method is simple and suitable for projects with low electric load and low ventilation.In view of the situation that the natural gas treatment station in desert area is short of water,electricity and dust outside,it is very important to design the high voltage frequency conversion chamber with large power load and ventilation to ensure the normal power supply in the station area,This paper discusses the design scheme of high voltage frequency conversion chamber for several large projects in China,and chooses the design idea suitable for the substation and distribution room in desert area.
