Device for converting ventilation load of high ventilation frequency space to ventilation load of low ventilation frequency space, and method for handling ventilation load of high ventilation frequency space in a building having a ventilation system

摘要

Apparatus for transforming the air exchange load of a higher air exchange rate space into the air exchange load of a lower air exchange rate space, including: a housing; an air inlet and at least one air outlet formed in the housing; a passageway extending through the housing and connecting the air inlet to the at least one air outlet; a circulation fan disposed in the passageway so as to draw the air of the higher air exchange rate space into the air inlet, through the passageway, and return that air to the higher air exchange rate space through the at least one air outlet; and a filter disposed in the passageway for purging noxious substances from the air passing through the passageway, whereby to transform the air exchange load of a higher air exchange rate space into the air exchange load of a lower air exchange rate space.
