摘要:
以地铁车站能耗和CO2排放量最多的车站通风空调系统作为研究对象，确定其CO2排放量计算方法，并探究其CO2排放特征。建立了基于生命周期理论的地铁车站通风空调系统CO2排放量计算模型。以计算模型和工程实例参数为依据，计算分析了典型车站通风空调系统生命周期CO2排放量。结果表明，案例车站的CO2排放强度明显高于普通建筑，每年单位制冷量所产生的CO2排放量达917.39 kg/(kW·年)；CO2排放量在运行阶段生命周期中占比最大，达97.87%；冷源水系统在各子系统中排放量占比最大，为39.42%。
Abstracts:
Metro station ventilation and air conditioning system that accounts for the most energy consumption and carbon emission is selected as the research objective to determine the calculation method of its carbon emission and explore the carbon emission characteristics. In this paper, a carbon emission calculation model for metro station ventilation and air conditioning system based on the life cycle theory is established, it calculates the life cycle carbon emissions of typical station ventilation and air conditioning system according to the calculation model and engineering example parameters. The results show that the CO2 emission intensity of the case station is significantly higher than that of ordinary buildings, and CO2 emission of the annual unit refrigerating capacity is 917.39 kg/(kW·year); the operation stage accounts for the largest proportion in the life cycle, reaching 97.87%; and the 39.42% emission of cold source water system accounts for the largest proportion among all subsystems.
