1、通风管道。在通风系统中，依靠通风管来送入或抽出空气。通风管的截面有圆形和矩形。通风管除直管外，由弯头、来回弯、变径弯，三通、四通等管件按工程实际需要组合而成。

1. Ventilation duct. In the ventilation system, air is fed or extracted by means of ventilation pipes. The cross section of the ventilation pipe is circular and rectangular. In addition to the straight pipe, the ventilation pipe is composed of elbow, back and forth bend, reducing bend, tee, cross and other pipe fittings according to the actual needs of the project.

2、各类风口。为了向室内送入或室内排出空气，在通风管上设置的各种型式的送风口或吸风口，以调节送入或吸出的空气量。风口的类型很多，常用的类型是装有网状和条形格栅的矩形风口，设有联动调节装置，其他的类型没有联动调节装置。风口分为单层、双层、三层及不同形式的散流器。

2. Various air outlets. In order to send or discharge air into or out of the room, various types of air supply outlets or suction outlets are set on the ventilation pipe to adjust the amount of air sent or sucked in. There are many types of tuyeres. The commonly used type is the rectangular tuyere with mesh and strip grille, which is equipped with linkage adjustment device. Other types have no linkage adjustment device. The tuyere is divided into single layer, double layer, three layers and different forms of diffusers.

3、阀门。安装于风管上的用以调节风量和关闭个别支管的通风部件。通风与空调工程常用的阀门有插板阀、蝶阀、多叶调节阀、圆开瓣式启动阀、空气处理室中旁通阀、防火阀和止回阀等

3. Valve. Ventilation components installed on the air duct to adjust the air volume and close individual branch pipes. The valves commonly used in ventilation and air conditioning engineering include gate valve, butterfly valve, multi leaf regulating valve, round open disc start valve, bypass valve, fire damper and check valve in air treatment room,

4、消声器。防止噪声传入室内所采用的装置。在空调工程中采用的有阻性捎声器、抗性捎声顺、共振性消声器和宽频带复合式消声器等。

4. Muffler. A device used to prevent noise from entering the room. In the air conditioning project, the resistive sound carrying device, resistant sound carrying device, resonant muffler and broadband composite muffler are used.

5、除尘器。是净化空气的一种设备，一般分为旋风式除尘器、湿式除尘器和袋式除尘器等。

5. Dust collector. It is a kind of equipment for purifying air. It is generally divided into cyclone dust collector, wet dust collector and bag dust collector.

6、通风机。是机械通风系统中迫使空气流动的机械。通风机是通风与空调系统的主要设备，根据构造原理分为轴流式通风机和离心式通风机两类。

6. Ventilator. It is the machinery that forces air flow in the mechanical ventilation system. Fan is the main equipment of ventilation and air conditioning system. According to the structural principle, it is divided into axial flow fan and centrifugal fan.

7、风帽。它用于排风系统的末端，它的作用是向室外排除污浊空气。按其形式分有：适用于一般机械排风系统的伞形风帽，适用于除尘系统的锥形风帽，适用于自然排风系统的简形风帽。

7. Hood. It is used at the end of the exhaust system. Its function is to remove dirty air to the outside. According to its form, it is divided into: umbrella hood suitable for general mechanical exhaust system, conical hood suitable for dust removal system and simple hood suitable for natural exhaust system.
