Industrial equipment will always cause the corresponding heat in the process of production, manufacturing and operation. If the heat generated in the past is not immediately discharged or digested, the calories formed in the process of operation will always be accumulated, especially the damage to the equipment is very easy, reducing the life of the computer.

地底車庫排風系統的二種方式，根據“通風機一送風管一正壓送風口”的排風方法和“排風系統口一通風管道一排煙風機”的排風系統方法來完成的。自然，排風系統可與通風管道系統合二為一，但這時排煙防火閥為防火閥，排煙風機為排煙系統.排風系統共用離心風機。

The two modes of the underground garage exhaust system are completed according to the exhaust method of "ventilator - air supply pipe - positive pressure air supply outlet" and the exhaust system method of "exhaust system outlet - ventilation duct - smoke exhaust fan". Naturally, the exhaust system can be combined with the ventilation duct system, but at this time, the smoke exhaust fire damper is a fire damper, and the smoke exhaust fan is a smoke exhaust system. The exhaust system shares a centrifugal fan.

此類排風系統存有如下所示難題：

This type of exhaust system has the following problems:

（1）通風管道在梁下穿梭，要占有一定的室內空間，假如要保持良好的層高，就必須土建工程提升樓高。

(1) The ventilation pipe shuttles under the beam to occupy a certain indoor space. If you want to maintain a good floor height, you must raise the building height by civil engineering.

（2）出風口的布局不太可能很聚集，出入口風力也是有一定限定，這就導致有通風管道出風口的地區氣旋流動性較快，而在轉彎處及一部分角落里，室內空氣質量就較靜止不動。那樣，車輛排出來的有害物質會滯流。

(2) The layout of the air outlet is unlikely to be very concentrated, and the wind force at the inlet and outlet is also limited, which leads to the rapid flow of cyclones in areas with ventilation duct outlets, while the indoor air quality is relatively static at corners and some corners. In that way, the harmful substances discharged by vehicles will stagnate.

（3）大規模的停車位，排風系統較為長，通風管道橫斷面較為大，不能防止地要與消防噴頭管道.橋架.電線套管等交叉式，既不容易解決，又危害停車位的美觀大方。空調通風工程安裝的優劣對空調的應用擁有非常大的危害，因此在安裝前要對通風管道開展有效的制定和合理布局，那樣能夠確保設計安裝的順利開展。

(3) For large-scale parking spaces, the exhaust system is relatively long, and the cross section of the ventilation duct is relatively large, which cannot be prevented from crossing with the fire sprinkler pipe, bridge, wire casing, etc., which is not easy to solve, but also endangers the beauty of the parking spaces. The advantages and disadvantages of the installation of central air conditioning and ventilation project have great harm to the application of central air conditioning. Therefore, effective formulation and reasonable layout of ventilation pipes should be carried out before installation to ensure the smooth development of design and installation.
