现在很多公建、写字楼的开发商只顾及采光，而不顾及室内通风，因此往往将窗户做成死窗或推拉式的半开窗，阻断或减少了自然风在室内的流动，这样的设计减少了前期投入，但在2003年非典流行过程中，由于大多数循环式空调被停用，暴露出来的问题非常突出。

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.

建研院空调所所长对当前建筑进行反思，认为，过去国内的建筑在通风管道空调系统的设计上只单纯强调降温与采暖，忽略了对空气质量的要求，空调的新风换气次数仅为0.54。目前，美国的公共建筑每人、每小时新风量平均达50立方米，与之相比，国内公建的新风平均量还不到欧美的一半，因此在换气次数方面应该加强提高。

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.

还有，现代楼宇的复杂建筑结构导致没有穿堂风，无法自然通风，只能采取人工机械通风系统。由于通风系统的成本和运行制约，加上许多人对通风与健康的紧密关联认识不足，尤其是人群密集的公共场所和娱乐场所，通风量远远达不到健康的要求，这就对人类造成了很大危害。

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.

现在有的楼盘和写字楼为了炒作，声称房子具有新风系统，其实根本不带新风系统送排风系统；即使有新风系统其新风量差别也很大，一般才达到5%15%。就是这么一点新风量由于没有能量回收功能，物业在运行空调系统时也经常关闭或减小新风量，以减少新风带来的巨大热能损失。

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.

更为严重的是，许多大酒店通风采用空调循环系统，客房窗户是全密封的，客人入住后，开窗呼吸新鲜空气的要求都难以达到；许多餐馆装修豪华，但窗户是假的，只是一个造型，通风完全靠排气扇，使得室内烟气、酒气难以消散；在家庭装修中，塑钢窗等新材料的使用，使房间密闭性增加，由此带来通风不畅的问题。

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，通风不畅是由很多原因引起的，应该分类处理，不能一概而论。

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

相信看了济南通风管道本文的介绍后，对这方面也会有自己的一番认识，以后针对的等问题也能很好的解决。

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