摘　　要：结合燃气企业服务站点办公建筑供暖热源实际,计算分析5种供暖热源的单位供暖面积能耗、碳排放。以某供暖面积1000 m^(2)服务站点办公建筑为例,计算5种供暖热源的综合费(为能源费与碳排放费之和)。电热泵机组能耗最小,其次是燃气机热泵机组,市政热源、燃气锅炉、直燃机组供暖热源的能耗均比较高。燃气机热泵机组的二氧化碳排放量最低,电热泵机组、燃气锅炉、直燃机组的二氧化碳排放量居中,市政热源的二氧化碳排放量最高。燃气机热泵机组的年综合费最低,市政热源的年综合费最高。在目前的碳交易价格水平下,碳排放费在综合费中占比不高,能源费仍是主导供暖热源经济性的因素。Combined with the actual heating sources of office buildings at service sites of gas enterprises,the energy consumption and carbon emissions per unit heating area of five heating sources are calculated and analyzed.Taking an office building with a heating area of 1000 m^(2) service sites as an example,the comprehensive fee of five heating sources(the sum of energy cost and carbon emission fee)is calculated.Electric heat pump units have the smallest energy consumption,followed by gas engine pump units,and the energy consumptions of municipal heat sources,gas boilers and direct combustion units heating methods are relatively high.The CO_(2) emissions of gas engine heat pump units are the lowest,the CO_(2) emissions of electric heat pump units,gas boilers and direct combustion units are in the middle,and the CO_(2) emissions of municipal heat sources are the highest.The annual comprehensive fee of gas engine heat pump units is the lowest,and the annual comprehensive fee of municipal heat sources is the highest.At the current level of carbon trading prices,carbon emission fee does not account for a high proportion of comprehensive fee,and the energy fee is still the factor that dominates the economics of heating sources.
