Against the background of the “Dual Carbon” goal, this paper focuses on the low-carbon optimization of heating medium parameters in central heating systems. Taking a central heating system in Harbin as an example (with the calculated outdoor temperature of −26 °C during the heating period and a heating load of 21,000 kW), it quantitatively analyzes the impact of changes in supply and return water temperatures and temperature differences on the system. The research aims to clarify the influence law of different parameter combinations on system energy consumption and carbon emissions, providing a theoretical basis and data support for central heating systems to achieve low-carbon and economical operation while meeting heating demands.

摘要

Against the background of the “Dual Carbon” goal, this paper focuses on the low-carbon optimization of heating medium parameters in central heating systems. Taking a central heating system in Harbin as an example (with the calculated outdoor temperature of −26 °C during the heating period and a heating load of 21,000 kW), it quantitatively analyzes the impact of changes in supply and return water temperatures and temperature differences on the system. The research aims to clarify the influence law of different parameter combinations on system energy consumption and carbon emissions, providing a theoretical basis and data support for central heating systems to achieve low-carbon and economical operation while meeting heating demands.
