With the acceleration of the urbanization process and the rapid development of the transportation system, more and more tall space public buildings such as stations and terminals serve people’s daily life. The construction of the station (terminal) has large space, high height, and large flow density. It is an important type of special transportation building with large scale, many systems, complex functions, complete facilities, and advanced technology. Its air -conditioning system has a large investment and high operating costs. Usually the power consumption of air -conditioning is 110-260kW.H/(M2 • A), which is 2 to 3 times that of ordinary public buildings. Therefore The key to energy conservation of tall space buildings such as machine buildings. In addition, due to the dense personnel of the station (terminal) building, the indoor air is dirty, how to improve the quality of indoor air is also a problem that high -space buildings such as stations and terminal buildings need to be solved.
