What are the keys to the construction of iron ventilation pipes? The following is an introduction by the professionals of iron ventilation pipes:

　　對于比較復雜的民用建筑，在設計階段，各工種(暖通、給水排水，供電照明與建筑)應協商好空間分隔，定出每種管道的標高范圍。

　　For more complex civil buildings, in the design stage, each type of work (HVAC, water supply and drainage, power supply and lighting and architecture) should first negotiate the space separation and determine the elevation range of each kind of pipeline.

　　一般情況下不得越出給自己規定的邊界。遇有個別管段要越界時應與其他工程協商。處理各種鐵皮通風管道相碰及協調的準則，一般為：“小管讓大管，有壓讓無壓”。例如，自來水管與風管相撞，則應當自來水管拐彎。冷、熱水管與下水管相碰，則應改變冷、熱水管道。施工前應設備總管的工程師，將各工種的管線，單線畫在一張平面圖上。每種管道用一種彩色筆。

　　Normally, they should not go beyond the boundaries prescribed by themselves. Consultation with other projects should be conducted when there is an individual pipeline crossing the boundary. The criteria for dealing with the collision and coordination of various iron ventilation pipes are generally as follows: "Small pipes let big pipes, pressure let no pressure". For example, when a water pipe collides with an air pipe, the water pipe should turn. When the cold and hot water pipes collide with the sewer pipes, the cold and hot water pipes should be changed. Before the construction, the Engineer in charge of the equipment shall draw the pipelines of each type of work on a single plan. Each pipe uses a colour pen.

　　在各交點處歸納其標高，看是否有矛盾之處，及時發現，將問題處理在安裝之前。為了減少出資，節省空間，降低層高，有些敷設無斜度要求的管道，能夠穿梁敷設(如自來水管道，消防噴灑干管等)。

　　Summarize the elevation at each intersection to see if there are any contradictions, find out in time, and deal with the problem before installation. In order to reduce investment, save space and reduce floor height, some pipes without inclination requirements can be laid through beams (such as tap water pipes, fire spraying trunk pipes, etc.).

　　對冷風機的保養能夠延長其運用的壽命，有效的阻止異味以及一些細菌的生成，不會對身體健康發生要挾;對濕簾清潔不會導致電機壓力的升高，電流的增大，能夠節約用電量。

　　Maintenance of the air cooler can prolong its service life, effectively prevent odor and the formation of some bacteria, and will not threaten the health of the body; cleaning the wet curtain will not lead to the increase of motor pressure, the increase of current, and can save electricity.

　　冬季來臨時，把冷風機里沒用完的水排放干凈，以防在冬季霜凍的時候，凍壞機器，影響第二年的運用。

　　When winter comes, the unused water in the air-conditioner should be discharged cleanly first, in order to prevent the machine from freezing during the winter frost, which will affect the operation of the next year.

　　其次咱們要防治鼠害，在冷風機不工作時，是鼠蟲過冬的適宜，咱們能夠放些老鼠網或是噴灑一些老鼠藥，防止老鼠對冷風機濕簾的破壞。

　　Secondly, we should prevent and control rodents. When the air cooler is not working, it is the best choice for the rodents to spend the winter. We can put some rat nets or spray some rat poison to prevent the damp curtain of the air cooler from being damaged by the rats.

　　經常性對水泵的檢查，假如發現損壞和松動現象要及時的對其進行維修。

　　Regular inspection of the pump, if found damages and loosening phenomenon to be timely maintenance.

　　終檢查電源、水源是否關閉，用特制的外套殼把冷風機外殼罩好。假如想要了解冷風機或者通風管道其他方面的常識的話，能夠咨詢咱們，咱們會誠摯為你效勞的!

　　Finally, check whether the power supply and water source are closed, and cover the cooling fan shell with a special coat. If you want to know the common sense of cold air blower or ventilation duct, you can consult us, we will sincerely serve you!
