Experimental analysis of performance and noise of VAV terminal devices

Analyses the performance of VAV terminal devices based on the experiment and relevant standards, providing the basis for solving the problem of controlling VAV terminal devices and noises in practical engineering applications. The installation of honeycomb screen in upstream of VAV terminal devices effectively guarantees the accuracy of terminal air flow rate measurement, and the resistance of honeycomb screen has little effects. Too small valve opening is not conducive to the regulating performance of VAV terminal devices and increases the terminal noise. The muffler downstream the VAV terminal device effectively reduces the noise and improve the acoustic environment.
