Research on Low-Carbon Medium Parameters of Central Heating Under the “Dual Carbon” Goal

This chapter delves into the critical role of heating medium parameters in central heating systems, particularly under China's 'carbon peak and carbon neutrality' goals. It examines how varying supply and return water temperatures influence system performance, investment costs, and carbon emissions. The analysis includes a detailed case study of a central heating system in Harbin, illustrating the impact of different temperature settings on radiator area, coal consumption, heat loss, and carbon emissions. The text also explores the economic implications of these parameters, providing a comprehensive overview of the trade-offs between efficiency and cost. By connecting heating medium parameters with investments in heat sources, networks, and users, the chapter offers practical insights for optimizing central heating systems to meet low-carbon objectives.
