Against the backdrop of energy shortages and ongoing structural transformation in the energy sector

developing efficient and clean heating technologies has become an urgent issue to be addressed within the industry. Thermochemical sorption heat storage offers advantages such as high energy storage density and low heat loss during long-term storage. It can be coupled with renewable energy sources to address the spatiotemporal mismatch between renewable energy supply and demand

thereby enabling clean heating. However

at the large-scale application level

thermodynamic analysis remains insufficient regarding the implementation of compression-assisted resorption heat storage in district heating. The integrated heating system based on thermochemical resorption heat storage regulation is initially proposed in this work. The mathematical model of the district heating system was constructed

and the dynamic characteristics of the system under different operation strategies were compared and analyzed

obtaining the optimal operation strategy of the system

The heat pump and CRTB respectively contribute 456.2 MWh and 847.5 MWh of seasonal heat

respectively

reducing heat station output by 43.7 %. The practical application value of the compression-assisted thermochemical resorption heat storage technology has been proved. Taking a typical residential community in Beijing as an example

by adopting the optimal operation strategy

the entire heating season reduced coal consumption by 623.4 tons and carbon dioxide emissions by 1697.9 tons. The findings of this study provide some insights for the large-scale district heating application of thermochemical sorption heat storage systems.
