siseõhuvahetust

Siseõhuvahetus refers to the process of exchanging indoor air with outdoor air. This is a crucial aspect of maintaining healthy indoor environments and ensuring occupant comfort. Inadequate ventilation can lead to a buildup of pollutants, moisture, and odors, contributing to poor indoor air quality.

There are several methods to achieve siseõhuvahetus. Natural ventilation relies on wind and temperature differences to drive air movement through open windows, doors, and other openings. Mechanical ventilation systems, on the other hand, use fans to actively move air in and out of a building. These systems can range from simple exhaust fans to complex heat recovery ventilation (HRV) or energy recovery ventilation (ERV) units, which pre-condition incoming fresh air using the energy from outgoing stale air.

The rate of siseõhuvahetus is often measured in air changes per hour (ACH). Different building types and occupancy levels have recommended ventilation rates to ensure sufficient air exchange. Proper siseõhuvahetus helps to dilute indoor pollutants such as carbon dioxide, volatile organic compounds (VOCs), and particulate matter, while also controlling humidity levels. This contributes to improved health, reduced risk of respiratory issues, and enhanced overall well-being for occupants. Balancing the need for fresh air with energy efficiency is a key consideration in modern building design and operation.
