Evaluation of fixed and adaptive concentration thresholds for particle filter systems.

Publication Type: Academic Journal

Source(s): Indoor air [Indoor Air] 2022 Oct; Vol. 32 (10), pp. e13134.

Abstract: Particle filtration can effectively reduce indoor concentrations of particulate matter (PM) but may incur high energy use. This study evaluates fixed and adaptive concentration thresholds to automate the operation of filtration systems. Simulated envir...
