Thermoeconomic Analysis and Multi-Objective Optimization of a Combined Cooling and Power System Using Ammonia-Water Mixture: Case Study

This paper investigates a combined cooling and power (CCP) system driven by a low-grade heat source. This system is a combination of the Kalina cycle and an ammonia-water absorption refrigeration cycle. Based on a thermoeconomic mathematical model, a numerical simulation and an exergy destruction analysis are conducted. A parametric analysis is also performed to examine the effects of several key parameters on the thermoeconomic performances of the CCP system. The results show that condensers contribute most exergy destruction to the system. The parametric analysis verifies that the key parameters have a significant impact on thermoeconomic performance. A multi-objective optimization is conducted to obtain the Pareto frontier solution for the CCP system, which provides diversified choices for different design requirements.
