tilluftsförråd

A tilluftsförråd, often translated as supply air store or ventilation buffer, is a component within a mechanical ventilation system, particularly in buildings with demand-controlled ventilation or where fresh air requirements fluctuate. Its primary function is to temporarily store a volume of conditioned supply air.

This stored air acts as a buffer, ensuring that the ventilation system can meet peak demand for fresh air without immediate strain on the air handling unit. When demand for fresh air is low, the excess conditioned supply air is directed into the tilluftsförråd. When demand increases, this stored air is released to supplement the fresh air being directly supplied, preventing a drop in air quality or a system overload.

Tilluftsförråd can be particularly beneficial in spaces with variable occupancy or activity levels, such as conference rooms, auditoriums, or certain types of industrial settings. By decoupling the immediate supply of fresh air from the actual demand, it allows for more efficient and responsive operation of the ventilation system. The design and capacity of a tilluftsförråd are determined by the specific ventilation strategy and the anticipated fluctuations in air demand. They are typically integrated into the ductwork of the ventilation system.
