õhuvahetid
Õhuvahetid, also known as air exchangers or heat exchangers, are devices designed to facilitate the controlled exchange of air between different spaces. In the context of buildings, they are primarily used in ventilation systems to improve indoor air quality while minimizing energy loss. The fundamental principle behind an õhuvaheti is to transfer heat from outgoing stale air to incoming fresh air, or vice-versa, depending on the season.
During colder months, stale, warm indoor air is expelled from the building. As it passes through the
Modern õhuvahetid often incorporate features like filters to remove dust, pollen, and other airborne contaminants from
