The article describes the methods of construction of the additive non-stationary pattern of ventilation process. A generalized pattern of the ventilation system was developed, the impact of external factors on the ventilation process was studied, taking to the account the time lag.
Based on the experimental plot (flow rate - pressure) - (head - time) short-term and long-term forecast of the parameters of ventilation system was carried out.
Two fundamentally new patterns were implemented: two-dimensional or "flat", and the three-dimensional or "spatial" models of the ventilation process.
A simplified model of the ventilation process was developed. There is a research of input actions of parameters on the final result of the ventilation process. The dynamic characteristics of the object of research, ventilated area, were determined. The time lag of the process was estimated.
The transition and output functions were defined, allowing to determine the response of ventilation system to any sequence of input signals, if its initial state is knownReferences
