合肥某商业项目热源系统减碳设计方法

Design of Low-carbon Heating System for a Commercial Project in Hefei

“碳中和、碳达峰”已成为我国的重要战略目标,作为建筑物主要耗能系统的空调热源系统应具有适应能源系统转型的条件,即热源系统电气化。本文以合肥某商业项目为例,对空气源热泵及燃气热水锅炉联合运行热源系统的经济性及碳排放量进行了详细分析,得出当空气源热泵承担67%设计负荷时,既可以取得较可观的经济效益,又可以降低热源系统的年运行能耗及碳排放量。结合工程设计,为今后夏热冬冷地区的商业项目热源系统的减碳设计方法及电气化提供了思路。

"Peaking carbon dioxide emissions before 2030 and achieving carbon neutrality before 2060"has become an important strategic goal in our country.The air conditioning heat source system,which is the main energy consumption system of buildings,should have the conditions to adapt to the transformation of the energy system,that is,the electrification of the heat source system.Taking a commercial project in Hefei as an example,this paper makes a detailed analysis of the economics and carbon emissions of the heat source system of the combined operation of the air source heat pump and the gas-fired hot water boiler.It can achieve considerable economic benefits,and can reduce the annual operating energy consumption and carbon emissions of the heat source system.Combined with engineering design,it provides ideas of carbon reduction design methods and electrification of heat source systems for commercial projects in hot summer and cold winter areas in the future.
