Abstract

Nonlinear and linear temperature dynamic models of a heat exchanger were investigated for air conditioning control of coating and drying processes for photosensitive materials. The nonlinear model was derived from heat balance based on the assumption of lumped parameter system that the heat exchanger is divided into small parts in the direction of flow (divided cell model). In each part, the temperature of the heating fluid, heated fluid and heat transfer tube with fin are assumed to be uniform. Parameters involved in this model were estimated from experimental data of the step response characteristics of temperature. The linear model is obtained by linearizing this nonlinear model. It was confirmed that the dynamic behavior of temperature can be successfully expressed by both nonlinear and linear models. Both models are considered to be utilizable for process analysis and control system design of the air conditioning system under consideration.
