水源中央空调环境影响的生命周期评价

LIFE CYCLE ASSESSMENT FOR WATER SOURCE HEAT PUMP SYSTEM

从原材料获取、生产加工、运行使用和废弃后处理处置 4个阶段 ,对水源中央空调按污染排放和资源能源消耗2种类型进行输入、输出清单参数以及相应生命周期环境影响潜值的统计计算与分析。以水资源和燃煤发电为基础的水源空调运行使用阶段的环境影响明显突出。

In this paper, according to different life\|cycle stages of raw material acquisition, manufacturing, use, treatment and disposal after use, the input\|output inventory and environmental impact potential for water source heat pump system (WSHPS) were presented and analyzed based on the categories of pollution emission and resource consumption. The use of WSHPS, which characterized by water consumption and coal\|dominated energy supply, were identified as a stage with significant environmental impacts. The information from life cycle assessment for WSHPS can be helpful to the product improvement.
