The air change rate (ACR) in a room is a function of the ventilation supply or extract flowrate (in l/s or m3/h) and a function of the volume of the room (m3). The resultant air change rate, normally expressed as air changes per hour (ACH) (h-1), gives us an indication of how many times per hour the ventilation system provides the room with new fresh air.
