The film project is a new stadium built by Hai'an university of Nantong Institute of Technology. It covers an area of more than 20,000 square meters. The film gym is 111 meters long, 46 meters wide and 5,106 square meters. It has a basketball court, tennis court and badminton court. There is also a table tennis court that can accommodate up to 3,000 people.

The arena is currently the most advanced air film stadium in China. It is designed with a 3m glass curtain wall to improve the indoor visual effect. At the same time, it has a complete central air-conditioning, fire alarm system, fire and smoke exhaust device and automatic fire cannon. And other equipment and facilities.

The top of the film is equipped with the patented technology of zhongcheng fresh air ventilation. The indoor temperature sensor, humidity sensor and CO2 concentration sensor are used to collect the indoor environmental signal. The intelligent control system will start the fresh air according to the set parameters and procedures. The ventilation system is ventilated and cooled to ensure a comfortable indoor environment.

At the same time, the project adopts the patent technology of air cushion insulation of zhogncheng Company. Compared with the glass wool insulation technology adopted by traditional air film, it has the following advantages: 1. Due to the high light transmission of the air pillow, it is not necessary to turn on the light during the day, compared with the traditional gas. The membrane energy saving is more than 50%; 2. The heat insulation effect is more than 35% higher than the traditional glass wool insulation; 3. The traditional insulating glass wool absorbs water vapor easily, molds and breeds bacteria, and the air pillow insulation does not have the above problems, air quality better.

In addition, the project also adopts the patent technology of JRT steel cable net of zhongcheng company. Each steel cable is determined by computer with accurate three-dimensional force calculation, which can effectively resist natural disasters such as super typhoon and blizzard, and reduce the internal stress of the membrane. Reduce the risk of tearing of the film, prolong the service life of the film, and improve the overall safety of the film.
