44 air change rate
норма воздухообмена- количество воздуха в единицах объема в час, деленное на объем помещения; обычно выражается кратностью в час (АСН или АСРН). Значение нормы воздухообмена для тех или иных специфических условий может быть измерено с использованием ASTM Е 741-83, «Test Method for Determining Air Leakage Rate by Tracer Dilution» (Практический метод определения нормы утечек воздуха с использованием трассеров) см. также ventilating rate.
кратность воздухообмена- число смен объема воздуха в помещении в единицу времени.
