摘　　要：节能分析及优化已不只是能的量的问题,而是能的质与量的综合估价的问题。文中用VC++6.0编制了能与质综合评价的计算程序模块,用(火用)分析方法分析计算制冷系统循环各过程的(火用)损失、(火用)效率,并且分析影响(火用)损失的因素。找出了制冷系统节能部位和节能应采取的措施。给出一个易操作的计算软件可以方便地判断任何系统在(火用)损失最小,(火用)效率最大时,实现热泵节能优化的最佳方案。The energy analysis and optimization of heat pump system is not only about the quantity of the energy, but also mainly about the quality and quantity of the energy. Their calculation program is developed in the Visual C＋＋ 6.0. It is applied to calculate the exergy losses of the parts of the system. The parts and the measures of the energy conservation are proposed, in results the exergy loss of the whole heat pump system reaches the minimum one, the exergy efficiency of the system is at the maximum one, the optimization and the energy conservation of the system is realized.
