摘要
Abstract
An allocation model of CCHP (combined cooling heating and power) products cost based on the symbolic exergoeconomics method (SEM)are presented. The model takes into account both the non-energy and the energy cost, and obtains the final cost by calculating the exergy consumption and the non-energy cost input during formation of products. It is observed that the model can show the cost of each exergy flow and evaluate the participation degree of non-energy cost as well, which reflect the cold, heat and electricity product cost objectively. The comparison between two cold productions, one from macro-CCHP and the other from electricity chiller, shows that the former contributes to energy conservation and pollution reduction remarkably though its total cost is higher than the latter. Sensitivity analysis of coal price, depreciation period and loan interest rates shows that the main risks of cold product come from investment market, while the main risk of electricity product and heat product comes from raw material market.关键词
