分析了各子系统性能和补充燃料对冷热电联产系统性能的影响，确定了使冷热电联产系统节能的条件。建议以燃料节能系数(FESF)作为评价热电联产系统的标准，并以热电联产的燃料量为依据。在分析如何将回收的热能分配给制冷和供热两个子系统之后，可以确定最优的分配方式，以获得较好的系统性能。随着补充燃料量的增加，冷热电联产系统的性能会下降。当电网的性能得到改善时，冷热电联产系统的电效率就会提高，从而达到节能的目的。
Analyzing the effects of both the subsystems performances and the supplemental fuel on the performance of the combined cooling, heating and power (CCHP) system, the condition that enable CCHP to save energy could be identified. Here, it is suggested that the CCHP system should be evaluated by a criterion of FESF (fuel energy saving factor), and the fuel amount of CCHP is chosen as the basis in the parameter. After analyzing how to distribute the recovery of thermal energy to the cooling subsystem and the heating subsystem, the preferential distribution mode could be determined to obtain better system performance. As supplemental fuel amount increasing, the performance of the CCHP system will descend. When the performance of the electric grid is improved, the electric efficiency of the CCHP system will be increased to save energy.
