论文摘要：

The vapor compression heat pump (VCHP) is a widely-deployed energy-saving heating technology. As an integral part of VCHP system, the heat exchanger network (HEN) significantly influences overall system performance. The energy-economic-structural viability of the VCHP hinges on the interplay among HEN heat recovery, capital cost, and topology. Recently, a generalized VCHP design approach based on HEN optimization has been proposed. While this approach enhances system energy efficiency, it overlooks the increase in HEN capital cost and topological complexity. To address these limitations, this paper presents a novel co-optimization methodology for system economic performance and structural feasibility. This methodology integrates a levelized cost (LC) model to balance total initial investment with operational savings, and employs constrained mathematical programming to streamline the HEN topology. The proposed methodology is first validated by reproducing a published state-of-the-art system design. To further evaluate its applicability, two case studies are conducted: (1) waste heat recovery VCHPs design to demonstrate the methodological flexibility in addressing diverse demands, and (2) high-temperature VCHPs design focused on configuration streamlining. In the latter, two practical VCHPs are developed, optimally retaining efficient heat exchange matches while achieving economic-structural balance. Both practical systems achieve 11.1 % and 9.9 % reductions in LC versus a conventional cascade VCHP, respectively, by incorporating only one additional heat exchanger. These results demonstrate that the methodology is a scientific and practical tool for developing cost-effective VCHPs with streamlined configurations.
