When the noise generated by the air duct machine passes through the elbow of the air duct, the phenomenon of refraction absorption will occur, and the sound will be significantly weakened. <>
If the noise conditions of the air duct machine are allowed, the ceiling return air method can also be used, that is, the ceiling space where the air duct machine is located is regarded as the return air box, which also requires the workers to be more skilled and have more experience to do a good job. The use of ceiling return air can save materials, and it is also quick to install, which has a good effect on reducing noise. However, there are also disadvantages of using the ceiling return air, because the entire ceiling is used as an air conditioner, then the cold air in the room will be reduced.
The installation of ceiling return air also has high requirements for space, and the smaller the space, the better. <>

Anonymous users2024-02-07Summary. Hello Kiss Branch damper or distribution damper. These dampers are installed in front of the air branch line or distributor to control the distribution and regulation of the air flow.
They are able to adjust the direction and magnitude of the air flow to ensure that the air flows to the individual branches or air distributors. Branch dampers are typically angled or T-shaped, while distributed dampers are typically linear or square.
In order to prevent the vibration of the fan from being transmitted to the room through the air duct and causing noisesound, often at the entrance and exit of the ventilator.
There are two common measures:1Install shock absorbers or elastic connectors.
This device can reduce the degree of fan vibration transmission to the air duct and reduce noise generation. 2.Sound absorbers or mufflers are installed at the inlet and outlet of the ventilator.
This device can absorb noise and reduce the degree of drowsiness transmitted to the room.
Most of the dampers used at the branch of the air duct or at the front end of the air distributor are:

According to the first data, it can be seen that the generated C is 16G+ because it is a complete reaction, according to the theorem of conservation of mass) and then the second reaction, B material is excessive, 8GA and 11GB can be completely reacted, and then when 8GA is completely reacted, the mass of C generated is half of the first data, that is, and the condition tells you that the generated C, that is, the molar mass is the mass divided by the amount of matter, and the molar mass is 134, So the relative molecular mass of c is 134.
It can be said that girls with a sense of superiority who have a sense of superiority will not like girls who are no longer young, because that kind of girl often has no first time, and the main thing is that people who do not have the first time may not be able to keep a person to old age.
