城乡融合背景下农村地区空气源热泵供暖能耗与碳减排潜力评估OA

Driven by the dual development of urban-rural integration and the goal of"dual car-bon",the low-carbon transformation of rural building heating systems has become the key.In or-der to systematically explore the influence mechanism for different degrees of integration on the air source heat pump(ASHP)energy consumption and carbon emission reduction effect,this pa-per focuses on the rural ASHP heating system,uses EnergyPlus to construct a building energy consumption model,and innovatively sets up three urban-rural integration scenarios:high,medi-um and low based on three factors:thermal insulation performance,per capita occupied area and comfortable temperature.By simulating the heat load and energy consumption characteristics of rural areas from 2015 to 2024,the carbon emission reduction is calculated in combination with the carbon emission factors of the North China power grid.The results show that:① the combined effects of ASHP heat load on climate and building energy efficiency are significantly different un-der different urban-rural integration scenarios,the overall moderate integration scenario is high-er,and the proportion of living space such as bedrooms is prominent,reflecting the heterogeneity of heating demand in functional areas.② The moderate integration scenario is the optimal scenar-io for carbon emission reduction because it is in the critical period of building and energy system optimization,and the multiple emission reduction paths are coordinated.③ The sensitivity of the influencing factors was ranked as comfortable temperature>insulation performance>per capita area,providing a scientific basis for the priority formulation of transformation measures.The conclusions drawn by this study not only provide a quantitative reference for the selection of rural clean heating technology,but also promote the practical application of the theory of urban-rural integrated development from the perspective of energy system optimization.
