Thermodynamic and Economic Performance Assessment of Double-Effect Absorption Chiller Systems with Series and Parallel Connections

Absorption cooling technologies converting excess heat and renewable resources to energy have shown progress in recent years. In this study, two 400 kW LiBr solution absorption chiller types with series parallel connected are analyzed over a range of parameter values better understand their applicability for different uses. Thermodynamic models the components were constructed validated. The performance chillers related transfer, energy, exergy, economy was comprehensively analyzed. operating investigated by considering external variables, including inlet water, chilled steam temperatures allocation ratio. results indicate that reaches higher exergy than series-connected chiller, but transfer economic lower. coefficient efficiency reference system 1.30 24.42%, respectively. Except efficiency, water temperature had positive impact on performance, while trends opposite. sensitivity analysis ratio showed decreases suitable would be 0.54.
