At present, universities in China generally divide dormitories according to departments and majors. The dormitory is divided before students enter school, so the cost of air conditioning is unaffordable for some students with poor family conditions. The unified installation of air conditioners undoubtedly greatly increased their learning costs. On the other hand, children from wealthy families are obviously not used to living in dormitories without air conditioning, especially in the hot summer in the south, especially in northerners. Without air conditioning, they can only play on the floor, which is unbearable for them and will also bring trouble to their lives.
Many answers mentioned that installing air conditioning would affect study. I want to say that this is a false proposition, and the dress of online mobile phones will "affect". There are people everywhere with air conditioning in summer, and so are Internet cafes and libraries. Many people go to these two places for the summer. People who want to study will still choose to study, and a miserable environment is not a necessary condition for learning.
Some people also mentioned security issues. I think the only thing to be solved is to severely investigate and deal with inferior high-power appliances such as hot instant hot pot and strengthen fire safety management in dormitory. Install more air conditioners at most to increase the burden of electricity consumption, which requires circuit rectification, and the power sector can do it.
