Kinetic Reactions

CONTAM provides the ability to model chemical reactions among project contaminants within zones of a building including the implicit supply and return nodes of a simple air-handling system. Kinetic reactions in CONTAM are modeled as first-order exponential functions between species that contain the paired first-order reaction rate coefficients between the reactant and product contaminants.

Each kinetic reaction can be associated with one or more zones within a project, and they can also be stored within a CONTAM library file and shared between different CONTAM project files.
