現在很多公建、寫字樓的開發商只顧及采光，而不顧及室內通風，因此往往將窗戶做成死窗或推拉式的半開窗，阻斷或減少了自然風在室內的流動，這樣的設計減少了前期投入，但在2003年非典流行過程中，由于大多數循環式空調被停用，暴露出來的問題非常突出。

Now a lot of public buildings, office developers only consider lighting, without regard to indoor ventilation, so often half window windows made dead window or push-pull, blocked or reduced the natural wind in the interior of the flow, this is designed to reduce the initial investment, but in the epidemic process of SARS in 2003, because the majority of circulation air conditioning is disabled, the problems exposed very prominent.

建研院空調所所長對當前建筑進行反思，認為，過去國內的建筑在通風管道空調系統的設計上只單純強調降溫與采暖，忽略了對空氣質量的要求，空調的新風換氣次數僅為0.54。目前，美國的公共建筑每人、每小時新風量平均達50立方米，與之相比，國內公建的新風平均量還不到歐美的一半，因此在換氣次數方面應該加強提高。

Chinese Construction Research Institute of HVAC which thought to reflect the current architecture design, past domestic building air conditioning in the ventilation duct system only emphasizes cooling and heating, neglecting the requirement of air quality, fresh air ventilation air conditioning is only 0.54 times. At present, the United States public buildings, per person per hour of fresh air volume average of 50 cubic meters, compared with the average amount of fresh air domestic public buildings is less than half of Europe and the United States, so in times of ventilation should be strengthened to improve.

還有，現代樓宇的復雜建筑結構導致沒有穿堂風，無法自然通風，只能采取人工機械通風系統。由于通風系統的成本和運行制約，加上許多人對通風與健康的緊密關聯認識不足，尤其是人群密集的公共場所和娛樂場所，通風量遠遠達不到健康的要求，這就對人類造成了很大危害。

Also, the complex building structure of the modern building cause no drafts, not only take artificial natural ventilation, mechanical ventilation system. Because of the cost and operation control of the ventilation system, and many people on ventilation and health is closely related to the lack of knowledge, especially in crowded public places and places of entertainment, the ventilation quantity is far less than the health requirements, which caused great harm to human beings.

現在有的樓盤和寫字樓為了炒作，聲稱房子具有新風系統，其實根本不帶新風系統送排風系統；即使有新風系統其新風量差別也很大，一般才達到5%15%。就是這么一點新風量由于沒有能量回收功能，物業在運行空調系統時也經常關閉或減小新風量，以減少新風帶來的巨大熱能損失。

Now some real estate and office buildings to hype, claim that the house has fresh air system, but it doesn't bring fresh air system ventilation system; even if there is a large quantity of fresh air fresh air system is the difference, generally only reach 5% to 15%. This is a new point of air volume, because there is no energy recovery function, the property in the operation of air conditioning system is often closed or reduce the small air volume, in order to reduce the huge heat loss caused by fresh air.

更為嚴重的是，許多大酒店通風采用空調循環系統，客房窗戶是全密封的，客人入住后，開窗呼吸新鮮空氣的要求都難以達到；許多餐館裝修豪華，但窗戶是假的，只是一個造型，通風完全靠排氣扇，使得室內煙氣、酒氣難以消散；在家庭裝修中，塑鋼窗等新材料的使用，使房間密閉性增加，由此帶來通風不暢的問題。

What is more serious is that many star hotel ventilation air conditioning circulation system, room windows are sealed, guests, open a breath of fresh air requirements are difficult to achieve; many restaurants luxury decoration, but the window is fake, just one other, completely rely on the ventilation exhaust fan, make indoor smoke, alcohol it is difficult to dissipate; in the home decoration, the use of new materials such as steel window, make the room airtight is increased, resulting in poor ventilation problems.

由此可知，通風不暢是由很多原因引起的，應該分類處理，不能一概而論。

It can be seen that poor ventilation is caused by many reasons, should be classified processing, can not be generalized.

相信看了濟南通風管道http://www.bnlfans.net本文的介紹后，對這方面也會有自己的一番認識，以后針對的等問題也能很好的解決。

I believe that after the introduction of Ji'nan ventilation pipe http://www.bnlfans.net this article, there will be some understanding of this aspect, and other problems can also be well resolved in the future.
