摘要:The Combined Cooling Heating and Power System (CCHP) system can achieve highly efficiency by energy cascade utilization, which is one of the core units of the integrated energy system in the future, with great development potential. Aiming at the complicated operation performance of the CCHP system, an operation characteristic analysis method is studied under multiple modes. Firstly, a typical simulation model of the CCHP system is established, while the energy flow is analyzed. Secondly, an evaluation system considering multi-dimensional indicators such as energy consumption, comprehensive cost and pollution discharge of the system is built. According to the electric and thermal load of a building, the capacity of the main equipment of the system is designed. Furthermore, the energetic, economic and environmental performances under "following electric load" (FEL) mode and "following thermal load" (FTL) mode are quantitively analyzed, comparing with the traditional separated providing system. The results show that this method reveals the advantages and disadvantages of the performances of the CCHP system under different operating modes, thus can provide a reasonable basis for the selection of operational strategies.
