Combined cooling, heating and power (CCHP) is getting more attention for its energy saving. There has been a large number of researchers focus on the system configuration and operating strategies. However, the analysis of the whole process of the system from planning to design and running is relatively few. This paper based on an actual project in China, which has been running for two winters. Based on the background, planning, design and operating of the project, this paper comparing the load results between design and running stages, and it is found that the cooling and heating load in the running time is much smaller than the designed load. But the performance of CCHP is indeed better than the other conventional systems in the same building load situation. Finally, this paper proposed some suggestions for the future CCHP projects in the different stages.
