Efficient modeling of adsorption chillers: Avoiding discretization by operator splitting

• Computationally efficient and accurate adsorption chiller model. Avoiding discretization of heat exchanger models by operator splitting. Model validation for two real-world chillers. Broad application range established in terms a characteristic number. 70% increase computational efficiency compared to state-of-the-art Reliable computationally are crucial improve the performance However, modeling chillers is challenging due intrinsic process dynamics. Currently, most often represented 1-d, lumped-parameter that use lumped all components but resolve exchangers one spatial dimension. Still, simulations require fine leading poor efficiency. To efficiency, here, an alternative approach proposed avoids applying The benefits demonstrated case studies. First, resulting model calibrated validated with experimental data lab-scale one-bed chiller: retains accuracy while increasing up 70%. Second, applied commercial two-bed excellent accuracy. Finally, validity tested varying ratio between overall transfer coefficient capacity rate fluid exchangers. shown be well suited conditions present
