那么，终究是什么导致了通风不畅？
那么，终究是什么导致了通风不畅？
So, what ultimately causes poor ventilation?
我国建研院空调所所长徐伟对当前修建进行反思，以为，曩昔国内的修建在空调体系的规划上只单纯着重降温与采暖，疏忽了对空气质量的要求，空调的新风换气次数仅为0.54。现在，美国的公共修建每人、每小时新风量均匀达50立方米，与之相比，国内公建的新风均匀量还不到欧美国家的一半。
Xu Wei, the director of the Air Conditioning Institute of China Construction Research Institute, reflects on the current construction and believes that in the past, domestic construction only focused on cooling and heating in the planning of the air conditioning system, neglecting the requirements for air quality. The number of fresh air changes for air conditioning was only 0.54. Nowadays, the average fresh air volume per person and hour in public buildings in the United States reaches 50 cubic meters, compared to less than half of that in European and American countries.
还有，现代楼宇的杂乱修建结构导致没有穿堂风，无法天然通风，只能采纳人工通风体系。因为通风体系的成本和运转制约，加上许多人对通风与健康的严密相关知道缺乏，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。
Moreover, the chaotic construction structure of modern buildings leads to the lack of ventilation and the inability to provide natural ventilation. Therefore, an artificial ventilation system can only be adopted. Due to the cost and operational constraints of the ventilation system, as well as the lack of strict knowledge about ventilation and health among many people, especially in densely populated public places and entertainment venues, the ventilation volume is far from meeting the requirements of health.
现在许多公建、写字楼的开发商只顾及采光，往往将窗户做成死窗或推拉式的半开窗，阻断或削减了天然风在室内的活动，这样的规划削减了前期投入，但在2003年非典盛行过程中，因为大大都循环式空调被停用，露出出来的问题非常杰出。
Nowadays, many developers of public buildings and office buildings only focus on lighting, often turning windows into dead or sliding semi open windows, blocking or reducing the activity of natural wind indoors. This plan has reduced initial investment, but in the 2003 SARS epidemic, due to the discontinuation of most circulating air conditioners, the problems exposed were very outstanding.
另一个更值得注意的现象是，有的楼盘和写字楼为了炒作，故意浮夸房子具有新风体系，其实底子不带新风体系；即便有新风体系其新风量一般才到达3％至15％。就是这么一点新风量因为没有能量收回功用，物业在运转空调体系时也常常封闭或减小新风量，以削减新风带来的巨大热能丢失。
Another more noteworthy phenomenon is that some real estate and office buildings, in order to hype up, deliberately boast that the houses have a fresh air system, but in fact, the foundation does not have a fresh air system; Even with a fresh air system, the fresh air volume varies greatly, usually only reaching 3% to 15%. Because there is no energy recovery function for the new air volume, properties often close or reduce the new air volume when operating the air conditioning system to reduce the huge heat loss caused by the new air.
