在安裝計算中，有一個暖通空調，其中通風系統(tǒng)是一個非常重要的環(huán)節(jié)。說明通風系統(tǒng)的操作方法及注意事項。
In the installation calculation, there is a professional HVAC, in which the ventilation system is a very important link. Explain the operation method and precautions of ventilation system.
首先，通風系統(tǒng)的安裝計算有兩種方法，一種是跟蹤法，另一種是變換法。這一次，我將討論轉換的應用。
First of all, there are two methods to calculate the installation of ventilation system, one is tracking method, the other is transformation method. This time, I will discuss the application of transformation.
通風主要考慮風口、風管、閥門、風機設備及一些附件。
The ventilation specialty mainly considers the air outlet, air duct, valve, fan equipment and some accessories.
本文主要強調通風系統(tǒng)中風管、風門操作注意事項:
This paper mainly focuses on the precautions for the operation of the wind pipe and the air door of the ventilation system
一、風道識別
1、 Air duct identification
對于風管的改造，首先要有一個內容要明確，那就是關于風管的標高。當使用高度調整命令查看時，結果有時會不同。這是因為管道的標高和管道是管道或管道的標高。當我們談論管道有多高時，我們把管道當做一條線。如果你畫一個導管，你會有不同的表示海拔的方法。底層，中間層，頂層。因此，在風管安裝前，要看圖紙上的風管頂部是平的，底部是平的，還是是平的，并相應地調整風管底部、和頂部的標高。(另外，在風管轉換時，也要有針對性地使用相應的風管)。
For the renovation of air duct, first of all, there should be a clear content, that is, the elevation of air duct. When you use the height adjustment command to view, the results are sometimes different. This is because the elevation of the pipe and the elevation of the center of the pipe or pipe. When we talk about how high the pipe is, we think of the pipe as a line. If you draw a catheter, you will have different ways to represent the altitude. Bottom, middle, top. Therefore, before installing the air duct, it is necessary to see whether the top of the air duct is flat, the bottom is flat or the center is flat on the drawing, and adjust the elevation of the bottom, center and top of the air duct accordingly. (in addition, when the duct is converted, the corresponding duct should also be used specifically.).
現(xiàn)在做風管的變換,這一步應該輸入以下方面:個是風管的材料,第二個是風管道的壁厚,第三是風管道的接口類型,第四是風管的保溫厚度。這些參數(shù)更好的描述，如果不是，請參考05n4-3的相關規(guī)定。
Now, for the transformation of air duct, the following aspects should be input: the first is the material of air duct, the second is the wall thickness of air duct, the third is the interface type of air duct, and the fourth is the insulation thickness of air duct. The best description of these parameters, if not, please refer to the relevant provisions of 05n4-3.
二、風閥的圖紙及注意事項
2、 Drawing and precautions of air valve
關于風閥可以進行改造，也可以直接繪制，方法可以參考改造設備。這說明了順風閥的一些特別之處。在管道行業(yè)中，閥門不是扣除管道長度，而是在風管中，風管閥門是扣除風管長度，對于不同類型的風管閥門，有不同的扣除方法。如下圖所示，有足夠的風管寬度，無論什么值，風閥只有扣一個固定值;有足夠的風管寬度就什么值，氣閥扣的長度固定加風管高度(或半徑);還有一種情況是管道的寬度與閥門的長度有對應關系。我們可以根據具體說明選擇不同類型的風閥。
The air valve can be modified or drawn directly. The method can refer to the modified equipment. This shows some special features of the downwind valve. In the pipeline industry, the valve does not deduct the pipe length, but in the air pipe, the air pipe valve deducts the air pipe length. For different types of air pipe valves, there are different deduction methods. As shown in the figure below, there is enough duct width. No matter what value, there is only one fixed value for the air valve. If there is enough duct width, the length of the air valve buckle is fixed plus the duct height (or radius). There is also a corresponding relationship between the width of the duct and the length of the valve. We can choose different types of air valves according to the specific instructions.
