Background
At present, the building industry in China develops rapidly, the building design and construction level is continuously improved, and people also put forward higher requirements on building space. At present, the development of urbanization leads building resources in cities to be less and less, so the building space must be more reasonably applied, and effective measures are taken to improve and optimize the space of a building structure. With the development of the recent movie industry, movie theaters become one of the important places for people to enjoy leisure, entertainment and consumption. A ventilation and air conditioning system is an essential component of a theatre building space. With the development of economy, the living standard of people in China is rapidly improved, and the environmental requirements of people on public culture places such as movie theaters and the like are higher and higher. The architectural space of a movie theater is different in shape from other architectural spaces and is generally designed in a fan-like shape. Compared with the conventional rule and stiffness of the movie theater building, the movie theater building is composed of two circular radius planes, a front circular arc plane and a rear circular arc plane, the aesthetics of the fan is applied to the design of the movie theater building, the unique geometric characteristics of the fan shape are utilized by the movie theater building, the size is gradually increased from the front end surface to the rear end surface, the visual field of rear-row audiences is wider, and the movie theater building is more comfortable and attractive.
