摘要

摘要: 针对氨气制冷系统当前的系统能效评价研究现状,提出了一种二维能效评价矩阵模型,在此基础上,结合当前常用的层次-模糊评价和信息熵评价方法的优缺点,提出了组合权重的评价方法.该方法运用最小二乘法确定联合使用层次分析和信息熵后的组合权重.通过实例对比验证,该方法具有更高的准确性,与系统的实际能效比变化趋势更一致,线性度高.该方法可实现系统的能效状态及时判断,通过调整参数可实现系统的运行更优化,减少无谓能耗.

Abstract: In order to evaluate the energy efficiency of the ammonia refrigeration system, a novel two-dimensional matrix model was proposed. Based on thorough analysis of the popular evaluation methods, analytic hierarchy process-fuzzy comprehensive evaluation and information entropy method, a new combination weight evaluation method was put forward with the least squire. What's more, for better performance comparison, necessary actual cases were conducted and it proved that the new method has better precision, higher linearity and greater consistence with actual energy efficiency. Also, the energy efficiency state can be assessed instantly with this method and by adjusting necessary parameters the system can operate more optimally with less energy consumption.
