Summary

The sorption/ desorption characteristics under the non-equilibrium conditions are extremely important for the refrigeration. The experimental test unit is set up, and the p-T-x curves of different working pairs are tested under the non-equilibrium working conditions. The results show that non-equilibrium sorption/ desorption processes are related with dual variables rather than a single variable. Then we tested the isobaric sorption/ desorption processes of chlorides. Results show that the hysteresis phenomena are related with the desorption enthalpy. Sorption/ desorption dynamic models are studied. For sorption process the model is in accord with D-A equation, but for the desorption process both D-A equation and Spinner model should be considered. The Arrhenius equation is used to fit the relation between reaction heat and desorption hysteresis. The results show that the non-equilibrium equations fit the refrigeration performance well, whereas the theoretical equilibrium curves have big error.
