本文建立了基于燃气-蒸汽联合循环的天然气冷热电联产（CCH P）系统数学模型，分析了应用于工业园区的CCH P系统的系统性能，研究吸收式制冷机供冷量、蒸汽轮机供热量及制冷机能效比等因素的影响。研究结果表明，一次能源利用率和相对节能率随吸收式制冷机供冷量的提高和蒸汽轮机供热量的降低而下降；吸收式制冷机能效比对相对节能率的影响不大；补燃提高了系统的一次能源利用率，补燃后增加的蒸汽用于供电比用于供冷更有利于提高系统性能。本研究对区域型冷热电联产系统的推广与应用具有指导意义。

A m athem aticalm odelofCom bined Cooling,H eating and Pow er (CCH P)system based on the gas-steam com bined cycle is established to evaluate the C C H P system perform ance for an industry park. T he effects of variables suchasabsorptionchillercapacity,steam turbineheatingcapacityandCoefficientOfPerformance (COP)ofchillersare discussed. It is found that fuel utilization efficiency and fuel energy saving ratio decrease as the absorption chiller capacity increase and steam turbine heating capacity decrease. T he chiller C O P has lim ited im pact on system perform ance.Supplem entalcom bustion leads to the increase in fuelutilization efficiency,and the system perform ance is higher as the steam obtained from supplem ent com bustion is used for electricity generation as com pared to cold supply. T he results are of significance for C C H P application and generalization in zones.
