The construction standard of university classrooms is stipulated in the "Standards for Classroom Construction in Colleges and Universities" promulgated by the Ministry of Education, but it is not stipulated that university classrooms must be equipped with air conditioning. Moreover, in some cold geographical areas, it is very common that university classrooms are not equipped with air conditioning. Therefore, it is generally not allowed to report the absence of air conditioning in university classrooms. However, if you charge for air conditioning but don't install air conditioning, you can report it.
