1）、采用新风承担所有负荷的二次回风方式：
1), two air return way by air to bear all the load:
空气净化工程优点：室内机组无湿源；方便做新风值班风机
The advantages of air purification engineering: indoor unit without wet source; convenient to do a new wind on duty fan
空气净化工程缺点：共用一个新风系统时，室内温湿度不能随便调节。对新风机组要求 较高。
Air purification engineering shortcomings: the use of a new air system, the indoor temperature and humidity can not be adjusted freely. On the new wind turbine requirements higher.
PS：也有每个系统单独新风预处理，温湿度控制精确，但是造价高。
PS: also have each system to separate the fresh air, temperature and humidity control is accurate, but the cost is high.
2）带再热的一次回风方式：
2) a return air way with reheat:
空气净化工程 http://www.jnjkjh.com/ 优点：参数方便控制，准确度相对高，对表冷器无特殊要
Air purification engineering advantages: convenient parameter control, accuracy is relatively high, no special surface air coolers
空气净化工程缺点：冷热抵消，能耗大，运行费用相对教高。
Air purification engineering shortcomings: cold and hot offset, high energy consumption, operating costs are relatively high.
PS；我一般采用这种处理方式，多数用在西南地区。
PS; I generally use this approach, most used in the southwest.
3）增设一次回风的二次回风方案。
3) two air return scheme needs a return air.
就是将回风分两部分，一部分直接与新风混合经冷却干燥--风机温升处理后与另一部分回风一起送如室内。部分回风承担负荷
Means the. The air is divided into two parts, part of the direct and fresh air mixed by cooling and drying air temperature rise after treatment with the other part of the return together to send such as indoor Take the load part of return air
空气净化工程优点：新风处理简单。比一次回风节能
The advantages of air purification engineering: fresh air treatment is simple. Such a return air ratio
空气净化工程缺点：系统管道多点。
Shortcomings of air purification engineering: system pipeline.
4）焓差特别大的地区，提前对新风采用除湿机除湿。再经过新风机组。。。其他同
4) in the region, the enthalpy difference is particularly large. And then through the fresh air unit... Others
空气净化工程优点：有针对性，特殊问题特殊处理
The advantages of air purification engineering: targeted, special issue special treatment
空气净化工程缺点：增加除湿机，造价高
Shortcomings of air purification engineering: increasing the desiccant, high cost
5）室内循环风，湿负荷还是新风承担。
5) indoor cycling wind, wet load or fresh air.
这种我一般不用。
This kind of I don't generally.
