Modelling and simulation aspects of a solar hot water system

The paper deals with the modelling and simulation aspects of the main compo nents of a solar hot water system. Mathematical model was developed to desc ribe the thermal behaviour and energy balance of different solar collectors and hot water storage tanks. Block-oriented simulation technique was used to obtain the solution of the dynamic model. For the identification of the model a laboratory scale measurement was carried out. The results of the si mulation could support the selection of appropriate components and sizing o f a solar domestic hot water system to be built. (C) 1998 IMACS/Elsevier Sc ience B.V.
