Time and Size Resolved Indoor/Outdoor Particles in an Empty Room.
Original language description
Finding the concentration Cin of a non-reacting pollutant in a room of volume V is the main objective of indoor air modeling. Cin is controlled by the ventilation rate ? of indoor and outdoor air (with concentration Cout), sources Q, and sinks S. Here wemeasured time and size resolved indoor and outdoor particle concentrations and compared the experimental results with the prediction based on simple mass balance model. MODELLING OF INDOOR PARTICLE CONCENTRATIONS The temporal evolution of the indoor concentration including contaminant sources and sinks can be under well mixed conditions described by the first-order linear differential equation dCin/dt = ? (Cout - Cin) + q (1) Here q = (Q-S)/V is combined sources and sinks term divided by the room volume. For constant ?, Cout, and q and for the initial condition Cin = Cin (0), the equation (1) has the solution Cin = e-?t Cin (0) + (1 - e-?t ) (q/? + Cout ) (2) As can be seen the solution has a decay following a single time exponent ?.
