【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.更多还原
