| 摘 要： | 建立了空调器运行过程能值分析模型,依据该模型构建了能值转换率(Tr)、净能值产出率(EYR)、环境负荷率(ELR)和能值可持续性指数(ESI)等能值指标,并给出了环境服务的计算式.随室外环境温度升高或室内回风温度降低,空调器的Tr增大、EYR减小、ELR增大、ESI减小,表明空调器消耗的资源增多,系统可持续性降低.能值分析比常规热力学分析深刻、全面,能值指标反映了系统包括能源在内的总资源利用效率.此外,能值分析实现了不同类型污染对环境影响的定量比较,发现空调器运行过程产生的热污染(能量型污染)所消耗的环境服务比物质型污染多7000余倍.

| Abstract: | The emergy analysis model of the operation of an air conditioner was established and some emergy indicators,such as transformity(Tr),net emergy yield ratio(EYR),environmental loading ratio(ELR)and emergy sustainable index(ESI),were proposed based on this model.Besides,the formulae of environmental services were put forward.With the increase of outdoor ambient temperature or the decrease of indoor return air temperature,Tr and ELR rise,while EYR and ESI diminish.Those indicate that the air conditioner consum... |
