项目摘要

In this paper, the authors focused upon the circulation of xmtter obtained from composting garbage and the production and use of reinforced concrete walls as exsamples of the circulation of metter inside and outside ofbuilding environneantal cotrol system, showed explicitely using exergy concept what is adequte matter circulation. The following was found.1. Numerical analysis on the flow of energy and the circulation of matter obtained from the once-carried-out project of coirposting garbage in Tokyo was done, using concept of exergy. The armount of exergy consmed for operating the composting plant is twelve times that of exergy contained by the produced vegetable. The anuunt ofexergy consuned Fr the delivery of the garbage and the compost is one-Fourth of the exergy contained by the produced vegetable. It is ixrportant to make the amount of exergy consumed for operating a composting plant, hopefully less than that of exergy contained by the produced vegetable, in order that the circul … More ation of matter obtained fivm composting garbage can be sustained.2. In the experirrent to exanine whether a thernelly-well-insulated conposting tank can fernent garbage sufficiently without auxiliary heating, there was no difference in several indices indicating the degree of maturity of the contents between two conposting tanks. This proves that a therimlly-well-insulated corrposting tank can ferment garbage sufficiently without auxiliary heating. The arrount of exergy consurrption ofLNG becones sixtirres that of the garbage in the case of a non-insulated coirposting tank, while a well-insulated conposting tank needs no exergy consurrption of LNG.3. In the production of reinfbrcing bar, 83% of the supplied exergy which includes the exergy of Fssil fuels, raw materials and water is consurred, 17% of the supplied exergy is fixed within the product. At the use of the reintbrcing bar , 2% of the fixed exergy is consuxied. In the production of concrete, 80% of the supplied exergy which includes the exergy of Fssil fuels raw materials and water is consurred , 20% of the supplied exergy is fixed within the product. At the use ofconcrete, 5% ofthe fixed exergy is consuned. Types of wall inish afect the arreunt ofexergy consuription in the course of the use of the walls. The speed ofexergy consuxiption is slower the Fllowing order : tiled , rmrtared , painted , and no-finish. To make a good use of fossil fuels and raw materials , it is important that the fixed exergy is consumed as slow as possible. Less

本文以垃圾堆肥过程中产生的物质循环和钢筋混凝土墙体的生产使用为例，阐述了建筑环境控制系统内外物质循环的具体情况，并用(火用)的概念明确地说明了什么是物质的充分循环。发现了以下几点。利用(火用)的概念，对曾经在东京实施的垃圾堆肥工程的能量流动和物质循环进行了数值分析。经营堆肥厂所需的火用总量是所生产蔬菜所含火用总量的12倍。在垃圾和堆肥的运送过程中产生的火用占生产蔬菜所含火用的四分之一。重要的是使运行堆肥厂所消耗的火用，希望少于所生产的蔬菜所含的火用，以便使电路…堆肥垃圾可获得更多的物质。在对保温良好的堆肥池是否能在没有辅助加热的情况下充分发酵垃圾的实验中，反映两个堆肥池内容物成熟程度的几项指标没有差异。这证明一个保温良好的堆肥池可以充分发酵垃圾，而不需要辅助加热。在无保温堆肥罐的情况下，液化天然气的(火用)回收是垃圾的六倍，而保温良好的堆肥罐不需要液化天然气的(火用)回收。在再生棒生产中，83%的供应火用(包括燃料、原材料和水的火用)被确认，17%的供应火用固定在产品内。在使用修复棒时，可节约固定火用的2%。在混凝土生产中，80%的供应火用包括Fssil燃料原材料和水的火用，20%的供应火用固定在产品中。在使用混凝土时，固定(火用)的5%是一致的。墙体类型影响墙体在使用过程中的火用节流。火用消耗的速度较慢，依次为：瓷砖、粉刷、喷漆和未涂装。为了更好地利用化石燃料和原材料，固定火用的消耗速度尽可能慢是很重要的。较少
