Abstract

The steam generating heat pump, capable of producing steam from waste heat, is one of the promising technologies for energy conservation and emission reduction in the industrial sector. In this study, a simulation model for the steam generating heat pump is developed and validated using an experimental test rig with R1233zd(E) as the working fluid. The model is utilized to compare the performance of two SGHP system configurations. Each configuration has its own advantages: the steam production of FSGHP is, on average, 3.7 % higher than that of DSGHP, while the COP of DSGHP is, on average, 0.17 higher than that of FSGHP. A new performance evaluation index for SGHP, COP_steam, is proposed. The quantitative impacts of the steam compressor and preheater on the system performance are assessed. The results showed that the introduction of the steam compressor could increase COP_steam by up to 1.2, while the preheater could enhance COP_steam by up to 0.16.

采用R1233zd(E)进行余热回收的直接和闪蒸热泵性能比较

蒸汽发生热泵是一种利用余热产生蒸汽的技术，是工业领域节能减排的重要技术之一。本文以R1233zd(E)为工作流体，建立了蒸汽发生热泵的仿真模型，并在实验台上进行了验证。利用该模型比较了两种SGHP系统配置的性能。每种配置都有各自的优势：FSGHP的产汽量平均比DSGHP高3.7%，DSGHP的COP平均比FSGHP高0.17。提出了一种新的SGHP性能评价指标COPsteam。定量评估了蒸汽压缩机和预热器对系统性能的影响。结果表明，蒸汽压缩机的引入可使COPsteam增加1.2，而预热器的引入可使COPsteam增加0.16。

期刊介绍： Energy is a multidisciplinary, international journal that publishes research and analysis in the field of energy engineering. Our aim is to become a leading peer-reviewed platform and a trusted source of information for energy-related topics. The journal covers a range of areas including mechanical engineering, thermal sciences, and energy analysis. We are particularly interested in research on energy modelling, prediction, integrated energy systems, planning, and management. Additionally, we welcome papers on energy conservation, efficiency, biomass and bioenergy, renewable energy, electricity supply and demand, energy storage, buildings, and economic and policy issues. These topics should align with our broader multidisciplinary focus.
