The optimal operation of an exhaust heat recovery system in a gas engine cogeneration is investigated in consideration of the influence of chilled and cooling water temperatures on the performance characteristics of exhaust heat and gas fired absorption refrigerators. First, a simulation calculation is carried out to evaluate the performance characteristics of absorption refrigerators. Second, an optimization calculation based on the mixed-integer linear programming is carried out to determine the on/off status of operation and energy flow rates of equipment. In a case study, it is clarified how the strategies for controlling the load of the gas fired absorption refrigerator affect the optimal operation and running cost of the system, and how the optimal operation is advantageous as compared with a conventional one.
