Abstract: Abstract:The expected goals of the gasfired combined cooling heating and power distributed energy system (DES/CCHP) are to reduce primary energy resource consumption, to raise the efficiency of energy utilization and to obtain better economic benefit. In order to achieve the goals, the rational configuration of the combined cooling heating and power distributed energy system (DES/CCHP) and equipments was researched, and the energysaving performance and the economic benefit of the system were analyzed. Some concrete suggestions were proposed for reader’s reference.

Key words: Keywords:distributed energy system (DES), gasfired combined cooling heating and power (CCHP) system, operation mode, rational configuration
