Optimization of Combined Cooling Heating and Power System (CCHP) by a Novel Hybrid Method

The importance of energy and shortage of its sources have necessitated appropriate planning for developing systems with high efficiency. Combined cooling, heating and power generation systems CCHP, are systems that used for increasing the efficiency of generated energy, while decreasing costs. Since the invention off CCHP systems, different methods have been provided for determination capacity of equipment and their optimization. In this research, at first these systems summary  are presented and then three main methods namely maximum load method (MLM), maximum rectangle method (heating MRM,h and electric MRM,e ) and relative equivalent uniform annual benefit method(REUAB), for determination of capacity of prime mover have been introduced. Then for a residential convened that its prime mover is gas engine, with consideration three mentioned methods and a new proposed method, for optimization the CCHP will be explained. Finally, the results of the optimization with applying real conditions for prime mover are investigated.
