Abstract : In this paper integration of gas engines with combined cooling, heating and power (CCHP) systems was studied. The gas engine model, organic Rankine cycle model, Rankine cycle model and single effect absorption chiller model were developed in Aspen HYSYS V7.3. The series and parallel combination of Rankine and organic Rankine cycle integration with the gas engine showed an increase of 7% and 15% respectively in both the overall system efficiency and power generated. The trigeneration system provided cooling duty of 18.6kW, heating duty of 704kW to district heating system with 3.9MW of power generated and an overall trigeneration efficiency of 70%. The system also gave a 9% increase in the power generated when compared to the gas engine without waste heat recovery whilst bottoming with Rankine cycle, organic Rankine cycle and absorption refrigeration system.
