【摘要】 对长春市民用建筑四种能源供给方案在同样的负荷水平下,进行节能、环保和经济效果分析。计算四种能源供给系统的一次能源消费量、二氧化碳排放量、初期投资、运行费用和单纯回收年数。计算结果为:与空调系统相比,锅炉系统、热主电从和电主热从的热电联产系统的节能率分别为-2.1%、21.2%和6.0%;二氧化碳排放量的消减率分别为-0.7%、24.1%和9.4%;单纯回收年数分别为18.1,8.2和4.6年。为长春市民用建筑采用CHP系统提供了可行性依据。更多还原

【Abstract】 This paper analyzes the effect of energy saving,environmental impact and economic performance when introducing Combined Heat and Power(CHP) system in residential buildings in Changchun under the same loads.According to calculated and given data to calculate primary energy consumption,CO2 emission,initial cost,annual operation costs and payback periods.The results are as follows: boiler system,CHP system energy saving rates are respectively-2.1%,21.2% and 6.0%,CO2 reduction rates are respectively-0.7%,24.1% and 9.4% and payback periods are respectively 18.1,8.2 and 4.6 years relative to the air-conditioning system.Provid the feasible references for Changchun to adopt CHP.更多还原
