Légmennyiség

Légmennyiség is a Hungarian term that translates to "air quantity" or "amount of air". It is most commonly used in the context of ventilation and air conditioning systems. The term refers to the volume of air that is moved or processed by a system over a given period of time. This is typically measured in cubic meters per hour (m³/h) or cubic feet per minute (CFM).

In building design and HVAC engineering, légmennyiség is a critical parameter for ensuring adequate indoor air quality, comfort, and safety. The required légmennyiség for a space depends on various factors, including the size of the space, the number of occupants, the type of activity taking place within the space, and the presence of any pollutants. For example, a conference room with many people will require a higher légmennyiség than a small office occupied by a single person.

Properly calculated légmennyiség is essential for diluting indoor air contaminants such as carbon dioxide, volatile organic compounds (VOCs), and odors. It also plays a role in maintaining comfortable temperatures and humidity levels. Insufficient légmennyiség can lead to poor air quality, discomfort, and potential health issues for occupants. Conversely, excessively high légmennyiség can result in wasted energy and unnecessary operational costs. Therefore, accurate determination and control of légmennyiség are fundamental to effective building ventilation.
