而随著国内老年人人口逐渐增加,逐渐迈向高龄化之同时,对於高龄者使用空间之室内环境品质相关议题之探讨,亦成为未来我们需加以关注之议题之一。主要为针对台南某安养中心室内环境因子进行检测调查工作,利用现场室内环境测定以取得有效的实测数据;再藉由汇整相关国际评估基准,并进行实测数据比对分析,建立老人安养中心对物理环境反应之特性。并以前期相关研究文献回顾与老人安养中心实测案例现场的实验,来了解不同空间物理环境特性之影响,并将结果回馈实际建筑及室内设计之用。调查工作项目包含:空气环境之PM10、CO、CO2、甲醛、TVOC;温热环境之室内温度、相对湿度、人体PMV、PPD;光环境之照度、均齐度、昼光率等因子调查。本研究结果可归纳以下几点结论: 1 所谓临床诊断医学乃相对於基础医学而言,是指实际与病人接触的医疗及护理行为中牵涉到的理论和技术;而建筑的临床诊断的定义应为建筑本体与室内外诊断、维护及改善所有可行的方式来延长建筑物的寿命,并确保人与室内环境空间品质的健康。建筑临床诊断目的为确保结构体与环境品质能继续使用,而能维持所需要的效能及承受能力。一个有效的维护计画体系是必须建立的 2 在建筑空间之问题改善、治疗与修复执行中,是一个精确与技术性的事项,其中包含找出问题、确定原因、评估结构应力强度、评估环境品质、评估修复与改善必要性、选择及执行一个适当的过程。其改善与修复也必须尊重建筑空间原有色彩与形貌,并保留原有记忆及文化。 3 在临床诊断中空间环境品质中,物理性环境问题与结构构件缺陷必须分别判断,诊断建筑空间之结构与空间舒适品质必须详细观察其症结性问题,才能发现任何隐藏及有潜伏性缺陷的原因。建筑本体诊断是观察出建筑本体之破坏原因,而是内外空间环境诊断目的在於的找出影响健康因素之症结性问题。 4 建筑本体与空间环境之预防评估目的为降低与抑制问题的再发生。然而,自然力的破坏与人为使用因素皆是影响建筑生命期之主要因素,找出病源问题就如同医生对病人的处理,包含了侦查、诊断、治疗以及预防。 5 本研究以外墙材料热传导率测试结果发现,屋面与东西向立面是承受辐射热最多的地方,尤以 RC 的建筑更甚,不透明部分的外壳能特性主要与壁体的热传透率即隔热能力有关,但是承受来自日射的吸热影响,因此增加隔热性能与降低日射吸热因子是对温热环境是非常重要的。

Through the flue gas and air characteristic analysis in supercharged boiler,the results showed that the value of parameters would increase with the increase of fuel consumption.And volume heat load of the furnace, fuel consumption, heat change between flue gas and convective heating surface and evaporation value would increase with the increase of compression ratio.The heat calculation would be different because of dissimilar thermal calculation in the turbo-compressor when the boiler load was changed.As the boiler load increased,heat loss in the turbo-compressor would increase and the efficiency of the boiler would decrease.The results of the boiler start-up simulation showed that the time of start-up would decrease with the increase of flue consumption ,but instantaneous pressure amplitude would increase.Steam water"s dymamic diversification would be more complex than flue gas"s,and dynamic characters of their parameters would be changed due to different boiler load and disturbance variable,which was shown by results of the simulation when boiler load was changed.
通过分析增压锅炉内的空气、烟气参数特性,发现随着锅炉负荷的增加,空气和烟气的各项参数值都相应的增加;炉膛容积热负荷、锅炉的燃料负荷随着增压比的提高成比例增加;随着增压比的增大,烟气与对流受热面的换热增加,蒸发量随之增加;由于涡轮增压机组在不同负荷下的热力计算不同而造成增压锅炉在不同负荷下的热平衡计算的不同;锅炉增压机组的总的热损失随着锅炉负荷的增加而增加,而增压锅炉的热效率随着锅炉负荷的增加而减少;锅炉启动模拟仿真结果中发现,锅炉启动时燃料量增加,锅炉的启动时间就会减少,但是瞬时升压速度会增加;而动态负荷变化模拟仿真结果中发现,锅炉汽水侧的变化相比烟气侧更为复杂,且在不同负荷和不同扰动量下,烟气侧和汽水侧的重要参数动态特性是不同的。
