Salt impregnated desiccant matrices for 'open' thermochemical energy conversion and storage - Improving energy density utilisation through hygrodynamic & thermodynamic reactor design

The study results clearly show that the concept of using perforated tubes embedded inside the heat storage material significantly improves performance by enhancing the contact surface area between air → absorbent whilst increasing vapour diffusion. The results suggest a linear correlation between thermal performance and moisture uptake, ΔT-Δw. Determining these operating lines will prove useful for predicting achievable temperature lift and also for effective design and control of thermochemical heat storage systems.
