It’s a technology that often gets taken for granted, but without it our classrooms would not be able to function. So what is the official business definition of a classroom unit ventilator? A classroom unit ventilator is an enclosed heating, ventilation, and air-conditioning (HVAC) system that provides heating, cooling, humidity control, and indoor air qualquality control in a single space.
