不同环境下通风管道安装有什么区别?

家居生活或办公场所中,室内通风很重要。通风系统就是实现通风这一功能,包括进风口、排风口、送风管道、风机、降温及采暖、过滤器、控制系统以及其他附属设备在内的一整套装置。下面列举一些具体应用上,风管安装的区别:
Indoor ventilation is very important in home life or office. Ventilation system is a complete set of devices to realize the function of ventilation, including air inlet, exhaust outlet, air supply pipe, fan, cooling and heating, filter, control system and other auxiliary equipment. The following lists the differences of air duct installation in some specific applications:
1、抽油烟的通风管道安装
1. Installation of ventilation pipe for lampblack
安装抽油烟机的通风管道,在进行设计的时候,要以国家的标准为准,并一定要有生产厂家的合格证书以及检验证书,通常通风管尺寸在2000*450左右,是比较大的通风管道了。
When designing the ventilation duct for installing the range hood, the national standard shall prevail, and the manufacturer's certificate of conformity and inspection certificate must be provided. Generally, the size of the ventilation duct is about 2000*450, which is a relatively large ventilation duct.
2、浴霸通风管道安装
2. Yuba ventilation pipe installation
安装浴霸通风管道规格尺寸需要300*300mm,或者300*600,其直径大概是在100到150之间,这个通风管道尺寸还是要根据家里的面积来选购一款大小合适的通风管道。通风管道的规格在40厘米以下的,其吊架的距离不得大于4米,如果通风管道规格是在40厘米以上的,其吊架的距离不得大于3米。
The specification and size of Yuba ventilation pipe installation need to be 300*300mm, or 300*600, and its diameter is about 100 to 150. This ventilation pipe size should be selected according to the area of the home. If the size of the ventilation duct is less than 40cm, the distance between the hangers shall not be greater than 4m. If the size of the ventilation duct is more than 40cm, the distance between the hangers shall not be greater than 3m.
3、新风系统通风管安装
3. Installation of ventilation pipe of fresh air system
新风系统主机、金属风管都应该做保温处理。应该在吊杆上安装减震器;新风输出口、排风输出口和主机之间的连接都应该采取安装消声器或用软连接来连接
The main machine of the fresh air system and the metal air duct shall be insulated. Shock absorbers should be installed on the suspenders; The connection between the fresh air outlet, exhaust air outlet and the main engine shall be installed with silencer or connected with soft connection
风管道风量计算
Air volume calculation of air duct
举例来说:如果风管截面积:0.2048平方米,管道里气流按20米/秒
For example: if the cross-sectional area of the air duct is 0.2048 square meters, the air flow in the duct is 20 meters / second
0.2048*20*3600=14745立方米/小时
0.2048*20*3600=14745 m3 / h
这就是这个管道需要的流量,其它照此计算
This is the flow required by this pipeline, and others are calculated according to this
通风管道内风速及风量的测定,是通过测量压力换算得到。测得管道中气体的真实压力值,除了正确使用测压仪器外,合理选择测量断面、减少气流扰动对测量结果的影响很大。测量断面应尽量选择在气流平稳的直管段上。
The measurement of wind speed and air volume in the ventilation duct is obtained by measuring pressure conversion. To measure the true pressure of the gas in the pipeline, in addition to the correct use of pressure measuring instruments, the reasonable selection of measuring section and the reduction of airflow disturbance have a great impact on the measurement results. The measuring section shall be selected on the straight pipe section with stable air flow as far as possible.
