参照相关标准,对变风量系统末端装置的性能进行了实验分析,为实际工程应用中存在的末端调节问题和噪声问题的解决提供依据。变风量末端装置安装时在进口加装整流栅,可以有效保证末端风量在调节范围内的测量精确性,且整流栅阻力可忽略。末端装置阀门开度过小不利于末端的调节性能,还会增加末端的噪声。变风量末端装置后加装消声器能有效降低噪声,提高声环境的舒适性。
With reference to the relevant standards, the performance of the end device of the VAV system is experimentally analyzed, which provides the basis for the solution of the end adjustment problem and noise problem in practical engineering applications. VAV installation at the installation of imported rectifier grid installed, you can effectively ensure that the end of the air flow in the adjustment range of measurement accuracy, and the rectifier gate resistance can be neglected. End valve opening is too small is not conducive to the end of the regulatory performance, but also increase the end of the noise. Variable air volume after the installation of muffler device can effectively reduce the noise and improve the acoustic environment comfort.
