专注通风管道加工·排烟罩

　　1. General gas supply pipe

　　就像安装在墙上的分体一样，酒店房间是由安装在天花板上的机器(FCU，风机盘管的技术术语)来冷却的。风管的尺寸一般在1000mm * 150mm左右，完全无法爬升，而且一次爬升会碰到风机盘管，显然不能使用。

　　Just like the split on the wall, hotel rooms are cooled by a ceiling-mounted machine (FCU, technical term for fan coil units). The size of air duct is generally about 1000mm * 150mm, which is totally unable to climb, and once climbing, it will encounter fan coil unit, which obviously can not be used.

　　2. 新鲜空气管道

　　2. Fresh Air Pipeline

　　这些管道的设计目的是为酒店客人提供新鲜的室外空气，并根据里面的人数来调整尺寸。根据美国通风、制冷和供暖协会(ASHRE)的数据，每人每秒需要8升新鲜空气。即使以每人每秒16升的速度，一间可容纳两个人的客房，其新鲜空气管道的尺寸也约为320毫米乘200毫米。很明显，它不会成功。

　　These pipes are designed to provide fresh outdoor air for hotel guests and to adjust the size according to the number of people inside. According to the American Association of Ventilation, Refrigeration and Heating (ASHRE), each person needs 8 litres of fresh air per second. Even at a speed of 16 litres per person per second, a room can accommodate two people, and the size of its fresh air duct is about 320 millimetres multiplied by 200 millimetres. Obviously, it will not succeed.

　　3.排风管道

　　3. Exhaust duct

　　旅馆房间的卫生间将会有废气。一方面，排风可以去除卫生间异味，另一方面，可以保证室内外空气压力的平衡。正常情况下，排风量为新风量的80%，因此自然排气管比新风管小。

　　There will be exhaust gas in the bathroom of the hotel room. On the one hand, exhaust can remove the odor of toilet, on the other hand, it can ensure the balance of indoor and outdoor air pressure. Normally, the exhaust volume is 80% of the fresh air volume, so the natural exhaust pipe is smaller than the fresh air pipe.

　　此外，如何进入风道也是一个问题，如果在不破坏天花板的情况下，一般只能通过通道或露天供气爬上天花板。

　　In addition, how to enter the air duct is also a problem. If the ceiling is not destroyed, the ceiling can only be climbed through the passage or open air supply.

　　对于酒店客房，只有在风机盘管、空气阀、排水管下才能进入。所以要想进去是不可能的，除非特工有一种工具来切断风管。

　　For Hotel rooms, only under fan coil units, air valves and drainage pipes can they enter. So it's impossible to get in unless the agent has a tool to cut off the duct.
