Abstract

The invention discloses a ventilation louver with adjustable resistance and noise reduction, which includes a louver frame and noise-eliminating blades. The ventilation louver also includes a sensor and a control terminal. The sensor is arranged on one side of the louver frame to detect temperature and / or changes in wind power, and the sensor is electrically connected to the control terminal, and the control terminal is electrically connected to the sound-absorbing blade. The invention can satisfy the air inlet pressure loss and noise reduction performance of the equipment, and simultaneously has the effects of achieving low carbon, environmental protection and energy saving.

Description

technical field [0001] The invention belongs to the technical field of mufflers, in particular to a ventilation louver with a muffler. Background technique [0002] With the improvement of people's living standards and quality, there are higher requirements for the quality of living environment, and noise pollution has become the focus of people's attention. In many ventilation systems, equipment creates airflow while emitting loud noises. Designers and engineers face the challenge of allowing air to circulate while preventing noise from spreading outside. Therefore, lower pressure drop and effective noise reduction requirements are very important evaluation criteria. At the same time, it must also be considered that architects will require economy, aesthetics and practicality. [0003] The general noise reduction of the noise reduction louvers is 5~15dB(A), and the noise reduction characteristics are medium and high frequency. The noise reduction performance of the louver...
