Abstarct: The combined cooling, heating and power (CCHP) systems are untis that use different types of energy in the best possible manner baxsed on a combination of different thermodynamic cycles. The use of waste heat from a cycle to make another cycle is common in these systems. For this reason, these hybrid systems have higher efficiency and lower emission levels than their baxse systems. Hence, many researchers have focused on analyzing these systems. baxsed on the above, in the present study, while presenting a new configuration of a CCHP system, a comprehensive analysis is performed baxsed on the energy, exergy, economic, environmental, exergoeconomic and exergoenvironmental models. Finally, the optimum value of the investigated parameters are sought for reaching the optimal operating conditions of the proposed system. The system configuration is baxsed on combination of regenerative Brayton and Kalina cycles (for power generation), an ejector refrigeration cycle (for cooling uses), and a heat exchanger between Kalina and Brayton cycles (for heating uses). In the proposed system, the use of regenerator in the Brayton cycle has two advantages: first, it increases the efficiency of the Brayton cycle; furthermore, by reducing the temperature of the waste gases, it minimizes the temperature difference between waste gases and working fluid of the Kalina cycle (this causes the reduction of the entropy generation). The problem modeling is done in EES software and the optimization procedure is done in Matlab software baxsed on the combination of NSGA-II approach and an AAN. The results illustrat that the highest rate of exergy destruction and its related cost is occurred in the combustion chamber of Brayton cycle (due to significant pressure drop and severe temperature changes within it). On the contrary, pump 2 has the lowest rate of exergy destruction and its related cost. Also, exergy modeling shows that the contribution of Kalina cycle to the total exergy degradation of the system is very low due to the nature of the operating fluid of this cycle (water-ammonia temperature profile due to variability can match the hot source temperature profile. As a result, there is better overlap and the amount of exergy degradation is reduced). The results of the parametric study indicate that the highest and lowest sensitivity of the evaluation criteria are related to changes in compressor pressure ratio and evaporator outlet temperature, respectively. Also, due to the interaction effects that occur with changes in design parameters in system evaluation indicators, the need for multi-objective optimization to achieve the conditions that all indicators are in good condition is necessary. Applying the multi-objective optimization, the optimum value of the four important system evaluation criteria is obtained as follows: energy utilization efficiency EUE_( opt)=71.41%, exergetic efficiency _(ex,opt)=31.53%, exergoeconomic criterion (Ex) ̇_(eco,opt)=8.30 $/GJ, and exergoenvironmental criterion (Ex) ̇_(env,opt)=156.53 kg/GJ.
