| Now air conditioning has a very close relationship with the people and its influence will be enhanced with the development of the economy. Because air conditioning is used to meet people's requirement for comfortable indoor environment, its some influences are invisible. With lapse of time, the negative effects on people have been exposed gradually. Constant temperature and constant humidity has resulted in some physiological and psychological illness in the people who were often in such indoor environment. Especially the SARS made us think about the rationality of traditional air conditioning. We has reasons to change old working of air conditioning in order to supply a healthy and comfortable indoor environment for people.In this thesis, we expatiated on the negative effects of traditional air conditioning and enriched the meaning of "Natural Indoor Environment" with dynamic thermal environment that imitated natural condition. We set up the new conception for "Natural Indoor Environment". Based on other productions from experiments, it put forward a dynamic curve of thermal environment and proved the feasibility. Then, we introduced the method to evaluate thermal comfort in dynamic indoor environment and dynamic environment's influences on quality indoor air. At last, we compared the new dynamic thermal environment with traditional one and found that new thermal environment could evidently save energy. The new indoor thermal environment accorded with Chinese traditional philosophical idea and style that people are longing for "Natural Indoor Environment". Moreover, it would not improve indoor and could save energy compared with old heat environment. Our country is short of all kinds of energy. When people are paying more attentions on natural environment, We should learn to respect to the nature , to create new ,healthy and active indoor environment. We believed that the dynamic indoor environment would enter our lives in the future. |
