| 当前中国能源结构仍以煤炭为主，替代难度大，非化石能源发展面临多重制约，产业的高耗能、高排放、低能效问题并存，绿色低碳技术亟需加强。工业过程供热占据能源消耗的一半，因此实现工业过程供热的低碳化是实现碳中和的重要部分。为达到工业过程供热所需的体量和温度，高温/蒸汽热泵需要深入研究和广泛推广。本文从国内外工业热泵技术现状，分析目前工业热泵通常采用的系统循环型式、制冷剂压缩技术、水蒸气压缩技术；结合第四代低全球变暖潜值制冷剂发展现状，给出环保工业热泵的适用制冷剂；提出工业热泵技术发展展望，最后结合双碳目标的实现和工业锅炉替代市场分析，展开了工业热泵应用场景的拓展分析。 |

| Abstract: |
| Currently, China's energy consumption is heavily reliant on coal, which is difficult to replace. The development of non-fossil fuels faces multiple constraints, and the industry is adversely affected by the issues of high energy consumption, high emissions, and low energy efficiency. Therefore, innovative low-carbon technologies urgently require further development. Heating accounts for half of all energy consumption; therefore, low-carbon heating is important for achieving carbon neutrality. To meet the capacity and temperature requirements of industrial heating, high-temperature water/steam heat pumps must be developed. This paper presents an analysis of the current status of industrial heat pump technology, including system cycles, refrigerant compression technology, and steam compression technology. Based on the development status of fourth-generation low-global warming potential refrigerants, the corresponding heat pump technologies should be well developed. Furthermore, industrial heat pump development prospects are discussed based on the development status and applications. Finally, application scenarios are predicted based on the market capacity and carbon reduction potentials. |
