Tuloilmanvaihdossa

Tuloilmanvaihdossa refers to the process of introducing fresh outdoor air into a building's ventilation system. This is a crucial component of maintaining indoor air quality and ensuring a healthy and comfortable living or working environment. Fresh air is necessary to replace stale air that has been recirculated and has accumulated pollutants such as carbon dioxide, volatile organic compounds (VOCs), and moisture.

The intake of fresh air can occur through various means. In natural ventilation systems, this is achieved through open windows, doors, or passive air vents. In mechanical ventilation systems, such as those found in modern homes and commercial buildings, fresh air is actively drawn in by fans. Often, this incoming air is filtered to remove dust, pollen, and other airborne particles before it enters the building.

In many mechanical systems, the incoming fresh air is also pre-conditioned. This means it can be heated in colder months or cooled and dehumidified in warmer months to maintain a comfortable indoor temperature and humidity level. Heat recovery ventilation (HRV) and energy recovery ventilation (ERV) systems are advanced forms of mechanical ventilation that pre-condition incoming air by transferring heat and/or moisture from the outgoing stale air, thereby improving energy efficiency. Proper tuloilmanvaihdossa is essential for occupant well-being, preventing issues like stuffiness, headaches, and the buildup of harmful contaminants.
