热电冷联产系统节能性分析
Energy efficiency of cogenerated heating, electricity and refrigeration systems
摘要：
为评价热电冷联产与热电联产、冷分产及热电冷分产的节能性，建立了相应的节煤量、当量热力系数、热电冷联产系统供电煤耗3种评价指标的数学模型，并应用于对国产供热式机组的评价，认为热电冷联产系统节能是有条件的，并与评价指标有关，节煤量指标适用于分析热电冷联产系统节能性。
Abstract：
In order to compare heating, electricity and refrigeration triple-generation (HERT) system with combined heating and electricity (CHE) system plus electric refrigerator, and heat, electricity and cool produced respectively system, develops calculation models for evaluating coal saving, equivalent thermodynamic coefficient, power supply and coal consumption for HERT systems. Applies the models to heating units made in China. Points out that there is a condition for energy efficiency of HERT systems and it has relation to evaluating indexes. Coal saving index is applicable to analyse energy efficiency of HERT systems.
Keywords:cogenerated heating electricity and refrigeration system, energy efficiency, evaluation index
