摘　　要：本文根据东华大学4号学院楼燃气空调的冷热电联供改造方案,建立了楼宇冷热电联供系统的数学模型,以费用年值和(火用)效率作为目标函数对模型进行优化求解,并在天然气价格和电力价格变化的情况下,对联供系统和现有的分供系统进行了比较,其结果可以作为燃气空调系统进行冷热电联供改造的节能和经济性分析的参考。Based on the retrofit scheme of the air-conditioning system with direct-fired absorption chillers for a BCHP system at No. 4 College Building in Donghua University in Shanghai, the modeling of two optimization problems for the BCHP system is completed, the objective functions being the Annual Costs （AC） and exergetic efficiency of the system respectively. The solutions of the models under various prices of gas and electricity are compared with the results of the case of separate production of heat and power. Some interesting conclusions have been drawn and they could give some new knowledge to the analyses of energy conservation and economic benefits for the retrofits of air-conditioning systems with direct-fired chillers to BCHP systems.
