Dynamic simulation of a solar-powered solid absorption ice maker(I). Model of reaction fronts

In order to optimize the characteristics of solar-powered solid absorption ice maker, two dynamic simulation programmes have been developed, using different models of heat transfer process inside the reactor. The reaction front model was introduced, supposing the chemical reaction proceeded only in the boundary surface of the so-called reaction front. A general computational code DAL1 was used to solve the equations of the refrigeration cycle. Numerical results coincide with the experimental ones quite well. It shows the correctness of the adopted reaction front hypothesis and the computational programme can be used for the design of the solar powered solid absorption ice maker.
