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(chē)庫(kù)排風(fēng)系統(tǒng)的二種方式，根據(jù)“通風(fēng)機(jī)一送風(fēng)管一正壓送風(fēng)口”的排風(fēng)方法和“排風(fēng)系統(tǒng)口一通風(fēng)管道一排煙風(fēng)機(jī)”的排風(fēng)系統(tǒng)方法來(lái)完成的。自然，排風(fēng)系統(tǒng)可與通風(fēng)管道系統(tǒng)合二為一，但這時(shí)排煙防火閥為防火閥，排煙風(fēng)機(jī)為排煙系統(tǒng).排風(fēng)系統(tǒng)共用離心風(fēng)機(jī)。

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.

通風(fēng)管道安裝現(xiàn)存的問(wèn)題

Existing problems in ventilation duct installation

此類排風(fēng)系統(tǒng)存有如下所示難題：

This type of exhaust system has the following problems:

（1）通風(fēng)管道在梁下穿梭，要占有一定的室內(nèi)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(fēng)口的布局不太可能很聚集，出入口風(fēng)力也是有一定限定，這就導(dǎo)致有通風(fēng)管道出風(fēng)口的地區(qū)氣旋流動(dòng)性較快，而在轉(zhuǎn)彎處及一部分角落里，室內(nèi)空氣質(zhì)量就較靜止不動(dòng)。那樣，車(chē)輛排出來(lái)的有害物質(zhì)會(huì)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(guī)模的停車(chē)位，排風(fēng)系統(tǒng)較為長(zhǎng)，通風(fēng)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(chē)位的美觀大方?？照{(diào)通風(fēng)工程安裝的優(yōu)劣對(duì)空調(diào)的應(yīng)用擁有非常大的危害，因此在安裝前要對(duì)通風(fēng)管道開(kāi)展有效的制定和合理布局，那樣能夠確保設(shè)計(jì)安裝的順利開(kāi)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.
