Attempting towards sustainable development through the principles of cogeneration, proposal towards vapor absorption cogeneration cycle is presented with improved performance efficiency. MATLAB based simulations were done for utilization of condenser as heat rejecter and addition of reheater and other components to conventional absorption refrigeration cycle. The proposed combined heating and cooling cycle demonstrated optimum performance at ambient temperature of 20C, heat input temperature of 170C with 0.96 as weak solution concentration. The energy analysis presented total output of 1286.49kW, including process heat of 732.05 kW with cooling effect of 554.44 kW, with energy utilization factor of 1.193 at best conditions. The proposed cycle calls for further research and development aiming in favor of improvement in efficiency and better performance.
