工业供热“绿”变记：高温热泵将成为零碳园区的供热标配

Core Viewpoint - The industrial sector faces increasing carbon emission pressure under the "dual carbon" goals, with the heating systems in industrial parks being a critical area for achieving low-carbon transformation, particularly in zero-carbon parks [1] Group 1: High-Temperature Heat Pump Technology - High-temperature heat pump technology is emerging as a core solution for industrial zero-carbon heating due to its energy-saving, environmental, and electrification advantages [1][2] - The current challenge for industrial parks is achieving decarbonization in the heating segment, which is heavily reliant on fossil fuels, while other areas like lighting and air conditioning have already been electrified [2][3] - High-temperature heat pumps can meet temperature demands ranging from 40°C to 200°C, addressing the widespread low-temperature heating needs in various industries such as food processing and textile dyeing [2][3] Group 2: Energy Efficiency and Economic Viability - High-temperature heat pumps operate with a coefficient of performance (COP) of 3 to 6, meaning they can produce 3 to 6 times the heat energy for every unit of electricity consumed, significantly outperforming traditional coal-fired boilers [3][4] - Although the initial investment for high-temperature heat pumps is 5 to 10 times that of traditional boilers, their operational costs are only one-third to one-fifth of conventional heating methods, leading to long-term economic benefits [4][6] - Successful case studies, such as those in the brewing and petrochemical industries, demonstrate substantial cost savings and carbon emission reductions, with one example showing annual savings of over 40 million yuan and a reduction of 79,530 tons of CO2 emissions [6] Group 3: Market Development and Future Outlook - The current application of high-temperature heat pumps in industrial parks is less than 1%, primarily due to high initial investments and integration challenges [6] - The market is expected to mature with the increase of demonstration projects, and sales of high-temperature heat pumps are projected to reach 17,000 units by 2030 and 156,000 units by 2060 [7] - The transition from coal-based heating to green electricity heating marks a significant shift in industrial heating practices, supported by ongoing technological advancements and policy backing [7]
