Ilmanvaihtoyksiköt, or air handling units, are mechanical systems designed to control and distribute conditioned air within a building. These units are a crucial component of heating, ventilation, and air conditioning (HVAC) systems, ensuring indoor air quality, temperature regulation, and humidity control. They typically consist of several key components, including a fan, filters, heating and cooling coils, and a control system.

Air handling units can be classified into two main types: central and local. Central air handling units are typically located in a mechanical room and serve multiple zones within a building. They are connected to ductwork that distributes conditioned air to various parts of the building. Local air handling units, on the other hand, are installed in individual rooms or zones and serve a specific area.

The primary function of an air handling unit is to draw in outdoor air, filter it, and then condition it by heating or cooling it as needed. The conditioned air is then distributed throughout the building via ductwork or other distribution systems. Air handling units also play a role in maintaining indoor air quality by removing pollutants and allergens through filtration and sometimes by incorporating additional systems like humidifiers or dehumidifiers.

Modern air handling units are often equipped with advanced control systems that allow for precise regulation of temperature, humidity, and air quality. These systems can be integrated with building management systems (BMS) to optimize energy efficiency and ensure comfortable indoor environments. Additionally, air handling units can be designed to operate in conjunction with other HVAC components, such as boilers, chillers, and heat pumps, to provide comprehensive climate control solutions.

In summary, air handling units are essential for maintaining comfortable and healthy indoor environments by controlling temperature, humidity, and air quality. Their design and functionality can vary depending on the specific requirements of a building, but they all serve the fundamental purpose of distributing conditioned air efficiently and effectively.
