Õhuvahetuskiirus

Õhuvahetuskiirus, also known as air change rate or air exchange rate, refers to the measure of how much outdoor air is introduced into a building or a specific space over a given period. It is typically expressed in air changes per hour (ACH). This rate is a crucial factor in determining indoor air quality, as it directly impacts the concentration of airborne pollutants, such as dust, allergens, volatile organic compounds (VOCs), and carbon dioxide.

A higher õhuvahetuskiirus generally leads to better indoor air quality by diluting and removing contaminants more effectively. This is often achieved through natural ventilation, such as opening windows and doors, or mechanical ventilation systems, like exhaust fans and whole-house ventilation systems. Conversely, a low õhuvahetuskiirus can result in the buildup of indoor pollutants, potentially leading to health issues collectively known as Sick Building Syndrome.

The optimal õhuvahetuskiirus varies depending on the type of space, occupancy levels, and the activities taking place within it. For instance, residential spaces typically require a different ACH than commercial buildings or industrial settings. Building codes and health organizations often provide guidelines or standards for recommended air change rates to ensure adequate ventilation and maintain a healthy indoor environment. Monitoring and controlling õhuvahetuskiirus is therefore essential for occupant well-being and comfort.
