Aiming at some new-built factory in Shanghai with gas-fired internal-combustion generator units distributed energy system, based on the first law of thermodynamics and the second law of thermodynamics the article analyzes comprehensive energy utilization rate and exergy efficiency under different seasons and different operation modes. The results show that:under the heating condition this energy system has higher energy utilization ratio and exergy efficiency;compared with distributed system (city electric power and gas-fired boiler plus electric refrigeration) , the distributed energy system energy utilization rate increases 14%-19%and exergy efficiency increases 12%-15%.
