热电冷联供系统方案综合评价——某大学能源系统方案分析
Comprehensive evaluation of a CCHP system—a case study of a university’s energy system
摘要：
为满足某大学热、电、冷负荷需求，提出了四种能源供应方案，即常规的燃气锅炉方案、燃气-蒸汽联合循环热电冷联供方案、热泵型热电冷联供方案和自备式热电冷联供方案。从经济性、能源利用效率和环保等角度进行了分析评价，认为采用自备式热电冷联供方案最合适。

Abstract：
Puts forward four energy system schemes for a university to satisfy the demands of heating, power and cooling load, i.e. the schemes of conventional gas boiler, CCHP system with gas-steam combined cycle, CCHP combined with heat pump system, and CCHP system with electricity generated for owner’s consumption. Analyses and evaluates the economics, energy efficiencies and environmental protection of the four schemes. The conclusion is that the last scheme is the best.
