| This paper presents an analytical model of temperature and humidity intended for automated controlling of the process of drying structural wood. The temperature and humidity model was presented in the form of a sequence of local sub-models including: heat flow from heating water to air, heat flow from air to wood, heat flow through the dryer walls, and air exchange between the dryer and the environment. The development of the model made it possible to develop a control strategy for the drying process using predictive control algorithms, ensuring the desired quality of the dried wood on the one hand and the economics of the drying process itself in terms of its energy consumption on the other. |
