Ilmansiirtoa

Ilmansiirto is Finnish for the transfer or movement of air. The word combines ilm- meaning air with siirto meaning transfer, and it is used to describe the distribution of air within a space, system, or environment. The term can be encountered in technical, scientific, and engineering contexts as well as in meteorology and environmental studies.

Applications and contexts

In meteorology and environmental science, ilmansiirto refers to the movement and mixing of air masses driven by winds, temperature differences, and pressure gradients. It is important for understanding weather patterns, pollutant transport, and climate processes. In building services and industrial ventilation, ilmansiirto describes how air is distributed by ventilation systems, natural ventilation, ducts, and diffusers; it influences indoor air quality and energy efficiency. A common related parameter is the air exchange rate or air changes per hour, which quantifies how quickly indoor air is replaced.

Physiology and medicine

The concept of air transfer relates to breathing and gas exchange, but ilmansiirto is not always the standard clinical term. In medical contexts, terms such as ventilation (ilmanvaihto) and gas exchange are typically used to describe how air moves into and out of the lungs and how oxygen and carbon dioxide are exchanged.

History and terminology

Ilmansiirto has a long-standing presence in technical literature, standards, and regulation related to ventilation, indoor air quality, and atmospheric science. The term emphasizes the physical movement of air rather than the chemical or biological aspects of air interactions.
