Légkeringetés

Légkeringetés, translated as air circulation or ventilation, refers to the process of moving air into, out of, and within a building or enclosed space. This movement of air is crucial for maintaining indoor air quality, controlling temperature, and managing humidity. Natural ventilation utilizes passive methods like opening windows and doors to allow fresh air to enter and stale air to escape, driven by natural forces such as wind pressure and temperature differences. Mechanical ventilation, on the other hand, employs fans and ductwork to actively control air exchange.

A key aspect of légkeringetés is the exchange of indoor air with outdoor air to remove pollutants, such as carbon dioxide, volatile organic compounds (VOCs), and moisture. This is essential for occupant health and comfort, preventing issues like stuffiness, mold growth, and the buildup of odors. In many modern buildings, ventilation systems are designed to be energy-efficient, often incorporating heat recovery mechanisms (heat recovery ventilation or HRVs) that transfer heat from outgoing stale air to incoming fresh air, thereby reducing heating and cooling loads.

Proper légkeringetés is a fundamental component of building design and operation, impacting everything from the perceived freshness of the air to the long-term durability of building materials. The specific ventilation strategy employed depends on various factors, including climate, building type, occupancy, and desired indoor environmental quality. Effective air circulation contributes significantly to a healthy and comfortable indoor environment.
