    This research proposes a model for a solar combined cooling heating power (SCCHP) system that combines cooling, heating, and electricity generation. The system is precisely engineered to cater to the needs of government institutions, large-scale hospitals, and residential complexes located in Baghdad, Iraq. The system undergoes a 3E investigation, examining energy, exergy, and exergoeconomic aspects. The SCCHP system generates 210 kW of electricity, 3965 kW of heat, and has a cooling load of 249.4 kW. The system's energy efficiency was calculated to be 76.55%, while its exergy efficiency was judged to be 17.75%. The exergoeconomic factor of the SCCHP system was calculated as 63.32%, showing that the fraction of costs associated with exergy destruction is lower than the initial capital investment cost of the system. The exergoeconomic importance of the solar power tower collectors (SPTC) and ORC evaporator is most significant. An investigation is conducted into the impact of ORC working fluid change and ORT inlet temperature. Octane is more efficient from a work net and exergoeconomic standpoint, while R245fa is more efficient from an energy and exergy standpoint. Increasing the ORT inlet temperature reduces the work net, increases the total cost rate, and diminishes the thermal and exergy efficiencies of the system.
