A method for configurating cold and heat sources considering carbon emission costs
In 2020,carbon emissions of the building operation phase in China accounted for a-bout 21.7％of the country's total carbon emissions,with huge potential for carbon reduc-tion.However,the impact of carbon emission costs on the economy of cold and heat source schemes is seldom considered in the current selection of cold and heat source schemes.This paper proposes a method to configurate cold and heat sources which considers carbon emis-sion costs.A life cycle cost(LCC)mathematical model is established that includes the initial investment,operation and maintenance costs and carbon emission costs to finalize the cold and heat source scheme with economic advantages.The result shows that the carbon emis-sion costs have a non-negligible impact on the LCC of the cold and heat source scheme.The scheme may lose its economic advantage after the carbon emission costs are considered.Therefore,the proposed method for configurating cold and heat sources which considers car-bon emission costs is more applicable to the actual configuration of cold and heat sources.
