这个系统包括两个送风机（其中一个备用）、空气管和氧化空气分布管。
The system consists of two air blowers (one of them as a common spare), air piping and grid distribution pipe.
中央空调通风系统送风中的污染物是室内空气的主要污染源之一，主要的污染物是可吸入颗粒物和微生物。
The contamination in the central air conditioning duct system is the one of the principal contamination of the indoor air, it include inhalable particle and microorganism.
系统包括强制送风的风路系统或加热流体的管路系统，通过散热器传给空气。
The system also contains either ductwork, for forced air systems, or piping to distribute a heated fluid and radiators to transfer this heat to the air.
对低温空调系统送风特性进行了研究，着重于低温送风空气流动状况及其对室内环境的影响。
This paper presents an investigation in the diffusion performance and indoor of cold air distribution system.
强制送风系统通过风管送热风，热天风管也可用于空调强制送风也可过滤或连接空气净化器。
Forced air systems send heated air through ductwork. During warm weather the same ductwork can be used for air conditioning. The forced air can also be filtered or put through air cleaners.
而对于典型的双管系统，则由两条区域送风路径(一条用于热空气、一条用于冷空气)和一条区域回风路径组成。
A typical dual duct system would have 2 zone supply air paths - one for the hot air and one for the cold air - and 1 zone return air path.
