Airt Flow is a term used to describe the movement of air through a space or environment. It is a key factor in the design of buildings, as it affects the comfort of occupants and the efficiency of the building’s energy systems. Air flow is the result of the pressure differences between two areas, which cause air to move from the area of higher pressure to the area of lower pressure. This pressure difference is created by a combination of factors, including temperature, humidity, wind, and the shape of the building. The air flow rate is the amount of air that is moved through a space in a given amount of time. It is typically measured in cubic feet per minute (CFM). The air flow rate is important for ensuring that the space is properly ventilated and that the air quality is maintained. Proper air flow is also essential for controlling the temperature of the space, as it helps to regulate the amount of heat that is transferred from the environment to the occupants.
