压力无关型变风量末端的内部性能优化的研究

Internal Performance Optimization of Pressure Independent VAV Terminals

鉴于医院人流量大的区域采用传统的集中式空气处理方式不能满足舒适性要求,而考虑采用变风量末端装置。但普通的变风量装置无法满足工程中的调节要求,以及解决内部性能不足的问题。针对这些问题,进行了压力无关型的变风量末端装置通过内部风阀开孔的优化研究。实验结果显示,在一定范围内,静压越大,风量控制范围提高越多,而噪音与原来相比基本没有明显变化。为医院内采用和优化变风量末端装置提供一定参考。

Since the application of traditional centralized air conditioning system for crowded places in hospital cannot meet comfort demands,VAV terminals can be a better choice.But general VAV terminals also cannot meet the project requirements,the paper attempts to optimize performance of pressure-independent VAV terminals by making holes on air valve.The experiment results show that in a certain range,the bigger the static pressure is,the greater the ventilation control range increases,without any influence on noise.This research provides some suggestions on the application and optimization of pressure independent VAV terminals in hospital.
