图书馆是需要安静的地方,对声音的要求比较高,所以设计是应适当的考虑消声和减振设计,在消声方面设置一些消声弯头压箱。 The library uses air filters. The library is a place that needs to be quiet and has high requirements for sound. Therefore, the design should properly consider the noise reduction and vibration reduction design, and set some noise elbow pressure boxes in the noise reduction. However, in addition to airborne noise, air conditioning systems can also be transmitted through the structure and foundation of buildings.
Detailed introduction

The library is a place that needs to be quiet. The requirements for sound are relatively high, so the design should properly consider the noise reduction and damping design, and set some noise reduction elbows and noise suppression boxes in the noise reduction. However, in addition to airborne noise, air conditioning systems can also be transmitted through the structure and foundation of buildings. For example, the vibration generated by fans and pumps is transmitted to the foundation first, and then transmitted in the form of elastic waves from the foundation of the operating equipment to other rooms along the building structure, and then appears as noise. This noise is solid noise . Therefore, in order to reduce solid noise, an elastic member such as a spring, rubber, cork, etc. is provided between the vibration equipment and its foundation during the design to eliminate the rigid connection between the vibration equipment and the foundation. In addition, in order to prevent the transmission of vibration of the connecting pipelines, vibration isolation hoses are installed on the inlet and outlet pipelines of operating equipment such as fans, pumps, compressors, etc., and vibration isolation treatment is performed on the pipe hangers and through walls, such as Set some damping pads, shock absorbers, rubber, wood wedge gaskets, etc.

Considering that the library is quiet and has high requirements for noise, I use a centralized air-conditioning system. All air-processing equipment in the air-conditioning system, including fans, coolers, heaters, humidifiers, filters, etc. It is set in a centralized air-conditioning system room. After the air is processed and concentrated, it is sent to each air-conditioned room, and the machine room is set as the basement floor. This makes it easy to manage and maintain, and it has better control of noise, noise reduction and anti-vibration. easily. In addition, the fresh air volume of the air-conditioning system can also be adjusted according to the change of the season, saving operating costs, long service life, and relatively low initial investment and operating costs.

The height of the library is not high, and the temperature requirements are relatively strict, especially the high temperature constant temperature requirements of the library, so when designing the type of air outlet, design it as a diffuser and install it in the On the ceiling, the airflow is sent from the air outlet to the surroundings in a radial pattern. In addition, in order to allow readers to better accept the air supply environment, the diffuser is designed as a streamlined air outlet. The air duct of the entire air conditioning system is made of galvanized steel, which is durable and easy to install. The wind speed of the main air duct is designed to be 6m / s, the wind speed of the branch duct is designed to be 3m / s, and the wind speed of the air supply port is designed to be 0.8m / s.
