工业设备在生产制造运作的环节中会一直造成相对应的发热量，假如以前造成的发热量没有立即排出来或被消化吸收掉，运作操作过程中形成的卡路里又一直累加上来，尤其非常容易产生设备的损坏，降低电脑的使用期限。
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.
地底车库排风系统的二种方式，根据“通风机一送风管一正压送风口”的排风方法和“排风系统口一通风管道一排烟风机”的排风系统方法来完成的。自然，排风系统可与通风管道系统合二为一，但这时排烟防火阀为防火阀，排烟风机为排烟系统.排风系统共用离心风机。
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.

此类排风系统存有如下所示难题：
This type of exhaust system has the following problems:
（1）通风管道在梁下穿梭，要占有一定的室内空间，假如要保持良好的层高，就必须土建工程提升楼高。
(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）出风口的布局不太可能很聚集，出入口风力也是有一定限定，这就导致有通风管道出风口的地区气旋流动性较快，而在转弯处及一部分角落里，室内空气质量就较静止不动。那样，车辆排出来的有害物质会滞流。
(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）大规模的停车位，排风系统较为长，通风管道横断面较为大，不能防止地要与消防喷头管道.桥架.电线套管等交叉式，既不容易解决，又危害停车位的美观大方。空调通风工程安装的优劣对空调的应用拥有非常大的危害，因此在安装前要对通风管道开展有效的制定和合理布局，那样能够确保设计安装的顺利开展。
(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.
