Energy integration and economical optimization of small scale cchp system

Combined cooling, heat and power (CCHP) systems have the potential for energy efficiency through the utilization of waste heat. Using energy utilizing efficiency as optimization target, CCHP’s operation is optimized based on the principles of CCHP’s basic units: gas turbine, exhaust heat boiler and chiller. Operation parameter with best energy utilization efficiency is achieved. On the basis of the solution, the economic efficiency considering capital cost and operation cost relative to time is brought out, and economic operation optimization is carried out . EIS software is also used to predict CCHP’s performance. Then CCHP system using Capstone C60 micro gas turbine is operated to verified the result. The result in this paper can be the guidance for the design and operation of CCHP system in industrial and commercial building
