摘要：
This study conducted a comparative thermodynamic assessment of an integrated system that utilises a wet-ethanol fuelled HCCI engine to meet energy needs in a sustainable way. Utilising the waste heat from HCCI engines in conjunction with the Kalina cycle and NH3-H2O-based absorption refrigeration cycle (ARC), the system can simultaneously provide power, cooling, and heating. Various parameters were used to analyse the integrated system's performance. Results show that incorporating Kalina and ARC cycles effectively utilises the waste heat from the HCCI engine, increasing the thermal efficiency of combined cycle by 23.78% to 52.0% and exergy efficiency by 14.55% to 39.60%.
