1. General gas supply pipe

　　就像安裝在墻上的分體一樣，酒店房間是由安裝在天花板上的機(jī)器(FCU，風(fēng)機(jī)盤管的技術(shù)術(shù)語)來冷卻的。風(fēng)管的尺寸一般在1000mm * 150mm左右，完全無法爬升，而且一次爬升會(huì)碰到風(fēng)機(jī)盤管，顯然不能使用。

　　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. 新鮮空氣管道

　　2. Fresh Air Pipeline

　　這些管道的設(shè)計(jì)目的是為酒店客人提供新鮮的室外空氣，并根據(jù)里面的人數(shù)來調(diào)整尺寸。根據(jù)美國通風(fēng)、制冷和供暖協(xié)會(huì)(ASHRE)的數(shù)據(jù)，每人每秒需要8升新鮮空氣。即使以每人每秒16升的速度，一間可容納兩個(gè)人的客房，其新鮮空氣管道的尺寸也約為320毫米乘200毫米。很明顯，它不會(huì)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.排風(fēng)管道

　　3. Exhaust duct

　　旅館房間的衛(wèi)生間將會(huì)有廢氣。一方面，排風(fēng)可以去除衛(wèi)生間異味，另一方面，可以保證室內(nèi)外空氣壓力的平衡。正常情況下，排風(fēng)量為新風(fēng)量的80%，因此自然排氣管比新風(fēng)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，如何進(jìn)入風(fēng)道也是一個(gè)問題，如果在不破壞天花板的情況下，一般只能通過通道或露天供氣爬上天花板。

　　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.

　　對(duì)于酒店客房，只有在風(fēng)機(jī)盤管、空氣閥、排水管下才能進(jìn)入。所以要想進(jìn)去是不可能的，除非特工有一種工具來切斷風(fēng)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.
