Ventilation and air conditioning are two very different things. Unless it’s a central unit, the AC will be reusing the same air. In order to not die of lack of oxygen you need ventilation as well.
- myth2018 5y agoInterestingly, the articles I find about ventilation are indeed concerned about air quality. However, in my country, at least in the cities I've lived on, the idea of ventilation is mostly associated to cooling indoors (with air quality being a desirable byproduct). Maybe the differences between our climates led to differences between the concepts behind the same word. Or maybe there's a better word in English to express what I'm intending to (sorry, English is not my mother language).

But otherwise, a modern commercial HVAC system has a degree of mixing the air from the outside world to reduce gas and particulate concentrations. So in some systems, the HVAC is the ventilation system but when only ventilating, the flow rate is stepped down and the conditioning system is inactive.
