In order to study this question, author have done the following four things: first, have tested more than forty times in WUHAN—the typical region which hot in summer and cold in winter, second, use Ventilation Simulation software to do some simulation test; third, investigate some residenter's subjective recept over their house; fourth, reading some paper. Through studying ventilation, sunlight, periphery component, I have thorough discussed some house design theory compatible to this special climate.

为了这个目的，作者在武汉——典型的夏热冬冷地区进行了冬季与夏季大量实测实验、通风模拟软件PHOENICS的模拟试验、广泛的居民就住宅主观感受问卷调查，以及众多的文献阅读，从住宅的通风、日照、外围护构件等方面着手，深入研究了该地区住宅适应气候的设计方法，努力寻求一种最适合夏热冬冷地区住宅的气候适应方式。

They are extensively applied to the air conditioning project of ventilation and air exchange in the industrial and mining enterprises, the hotel, the museum, saloon bar, the gymnasium, an air conditioner, textile, shipping, the civil building etc. It is most suitable for pipeline pressurization, ventilation, air supplying and discharging in the general buildings and skyscrapers.
