現(xiàn)在很多公建、寫字樓的開(kāi)發(fā)商只顧及采光，而不顧及室內(nèi)通風(fēng)，因此往往將窗戶做成死窗或推拉式的半開(kāi)窗，阻斷或減少了自然風(fēng)在室內(nèi)的流動(dòng)，這樣的設(shè)計(jì)減少了前期投入，但在2003年非典流行過(guò)程中，由于大多數(shù)循環(huán)式空調(diào)被停用，暴露出來(lái)的問(wèn)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(diào)所所長(zhǎng)對(duì)當(dāng)前建筑進(jìn)行反思，認(rèn)為，過(guò)去國(guó)內(nèi)的建筑在通風(fēng)管道空調(diào)系統(tǒng)的設(shè)計(jì)上只單純強(qiáng)調(diào)降溫與采暖，忽略了對(duì)空氣質(zhì)量的要求，空調(diào)的新風(fēng)換氣次數(shù)僅為0.54。目前，美國(guó)的公共建筑每人、每小時(shí)新風(fēng)量平均達(dá)50立方米，與之相比，國(guó)內(nèi)公建的新風(fēng)平均量還不到歐美的一半，因此在換氣次數(shù)方面應(yīng)該加強(qiáng)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(xiàn)代樓宇的復(fù)雜建筑結(jié)構(gòu)導(dǎo)致沒(méi)有穿堂風(fēng)，無(wú)法自然通風(fēng)，只能采取人工機(jī)械通風(fēng)系統(tǒng)。由于通風(fēng)系統(tǒng)的成本和運(yùn)行制約，加上許多人對(duì)通風(fēng)與健康的緊密關(guān)聯(lián)認(rèn)識(shí)不足，尤其是人群密集的公共場(chǎng)所和娛樂(lè)場(chǎng)所，通風(fēng)量遠(yuǎn)遠(yuǎn)達(dá)不到健康的要求，這就對(duì)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(xiàn)在有的樓盤和寫字樓為了炒作，聲稱房子具有新風(fēng)系統(tǒng)，其實(shí)根本不帶新風(fēng)系統(tǒng)送排風(fēng)系統(tǒng)；即使有新風(fēng)系統(tǒng)其新風(fēng)量差別也很大，一般才達(dá)到5%15%。就是這么一點(diǎn)新風(fēng)量由于沒(méi)有能量回收功能，物業(yè)在運(yùn)行空調(diào)系統(tǒng)時(shí)也經(jīng)常關(guān)閉或減小新風(fēng)量，以減少新風(fēng)帶來(lái)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(yán)重的是，許多大酒店通風(fēng)采用空調(diào)循環(huán)系統(tǒng)，客房窗戶是全密封的，客人入住后，開(kāi)窗呼吸新鮮空氣的要求都難以達(dá)到；許多餐館裝修豪華，但窗戶是假的，只是一個(gè)造型，通風(fēng)完全靠排氣扇，使得室內(nèi)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(lái)通風(fēng)不暢的問(wèn)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(fēng)不暢是由很多原因引起的，應(yīng)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(jì)南通風(fēng)管道http://m.hwzxw.net本文的介紹后，對(duì)這方面也會(huì)有自己的一番認(rèn)識(shí)，以后針對(duì)的等問(wèn)題也能很好的解決。

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