摘　　要：以沈阳市某10万m^2的住宅小区为例,提出一种水源热泵与汽轮机耦合联供系统,采用数值计算的方法计算得出,耦合联供系统的一次能源利用率为1.07,供热耗煤量指标为6.72,将结果与其他供热方式进行对比分析,结果表明:耦合联供系统效率明显提高且耗煤量指标降低,具有显著的低能耗优势。该耦合系统虽然初期投资高,但年运行费用少,采用静态分析法对系统经济性进行分析比较,证明了系统的初期投资可在短期内进行回收,是一种既经济又节能的供热方式。Taking a residential community of one hundred thousand square meters in Shenyang as example. It proposes a coupling system of water source heat pump and steam turbine. It is calculated by the numerical calculation method that the primary energy utilization rate of the coupling system is 1. 07 and the index of heating coal is 6. 72. The results are comparatively analyzed with other heating methods. It turns out that the efficiency of the coupling system is improved and the coal combustion index is reduced. It has the significant advantage of low energy consumption. And although the initial investment of the system is high, the annual operating cost is low. The static analysis method is used to analyze and compare the system economy. We can prove that initial investment can be recovered in the short term. So the coupling system is an economical and energy-saving heating mode.
