楼宇冷热电联供系统成本分摊方法研究 总被引:5,自引:0,他引:5
多产品系统的成本分摊问题,是运用热经济学方法分析能量系统的关键环节之一。这里分析了现有的热电联供系统成本分摊的主要方法,指出了各种方法的实质,提出一种成本分摊的新方法——“价格系数法”。分别运用3种方法分摊了楼宇冷热电联供(BCHP)系统热电之间的成本,并进一步计算制冷部分的成本。实际BCHP系统的分析表明,“价格系数法”将联供带来的好处合理分配给冷电热三部分,有效解决了三联供系统的成本分摊问题。 相似文献

Building cooling, heating and power (BCHP) systems should play an important role in achieving the goals of energy efficient use and environment protection in China. It will make big sense when this type of system shows a good performance energetically and economically. An on-site BCHP system being the first in the country was installed and put to use five years ago. As the first step to evaluate the project, com~tations were made based on thermodynamic and themoeconomic theories to evaluate the system on full load and off-design conditions in summer. Discussion and analyses are made mainly in terms of exergetic efficiency and costs of unit amount of useful exergy produced in this paper. 相似文献
