In trams without air-conditioning, the temperature in the cabins is higher in summer, which may reduce the public's desire to ride.
The students of the Department of Integrated Systems and Design of the University of Science and Technology collaborated with tram companies to design a variety of new ventilation systems to improve air convection and lower the indoor temperature to make passengers feel cool.
The tram company pointed out that last year it had studied the improvement of the tram ventilation system to improve the quality of service, but has not yet implemented a timetable, and emphasized that it has nothing to do with the adjustment of fares.

Twenty-seven second-year students in the Integrated System and Design Course of HKUST’s School of Engineering worked with the tram company last semester to design a variety of environmentally friendly and innovative tram models to improve the passenger experience of trams.
In response to the problem of tram ventilation, some HKUST students designed to install a rib-shaped device on the upper layer of the tram to form an "air tunnel" to drive the air flow on the upper layer, and then cooperate with the open staircase design to bring air into the lower layer.
Another ventilation system is designed like a shell. By increasing the surface area of the components, the natural evaporative cooling effect is enhanced, so that the indoor temperature can be reduced by one to two degrees.
Zhang Yongheng, the commercial and brand director of the Hong Kong tram market, said that the company had studied improving the ventilation system of trams last year, but there is no timetable for implementation.

Zhang Yongheng, the commercial and brand director of the Hong Kong tram market, said that he would refer to the creative design of his classmates and pointed out that the company had studied the improvement of the tram ventilation system last year, such as installing a fan system with automatic temperature adjustment to enhance the comfort of trams.
Zhang Yongheng pointed out that the plan is still in the first stage, due to cost-effectiveness, inherent power supply network, tram structure, etc., there is no timetable for the implementation of the timetable. He emphasized that the plan has nothing to do with the adjustment of fares, and there is no plan to increase fares.
He pointed out that trams are one of the few public transportation vehicles that use natural wind. Under the epidemic, the air flow of trams makes it more healthy and it is worth keeping. Full installation of air-conditioning is not a short-term policy.
The student president of the University of Science and Technology was ordered to suspend school for one semester due to five actions including Zhou Zile's memorial service
Recruitment vacancies reduced by four-year students of the University of Science and Technology: It is hard not to consider the development of Beijing and Hebei to stay in Hong Kong when applying for a job.
HKUST’s recruitment vacancies fell by a quarter last year. Employment centers: focus on retail, tourism, etc.
