levegcsereszám
Levegcsereszám, meaning "air exchange rate" in Hungarian, refers to the number of times the entire volume of air within a building or a specific room is replaced by fresh outside air in one hour. This metric is crucial for assessing indoor air quality and energy efficiency. A higher levegcsereszám generally indicates better ventilation, leading to a reduction in pollutants, moisture, and odors. However, excessively high rates can result in significant heat loss during colder months and heat gain during warmer months, increasing energy consumption for heating and cooling systems.
The levegcsereszám is influenced by various factors, including the building's airtightness, the presence and type of
