The paper was motivated by the need to extend the utility of a solar water heating system by adjusting a heat exchanger in the hot water tank. An approximate dynamic model, composed of two linear differential equations, is used in an attempt to describe the transient performance of the system. This model is digitized in time, the result being in the form of a set of finite difference equations. Using experimental data the parameters of the model are identified by linear regression. These parameters are computed for various flow rates of the feed water through the heat exchanger in order to obtain a global representation of the system. The theoretical results were tested by simulation and were proved to be sufficiently close to the experimental ones. © 1974. (EN)
