Fundamental Study on the Circulation of Matter Inside and Outside of Building Environmental Control System

本文以建筑环境控制系统内、外水表循环为例，以堆肥垃圾获得的污泥循环和钢筋混凝土墙体的生产和使用为例，明确地说明了什么是充分的物质循环。发现如下：1。利用能的概念，对东京某一次性垃圾焚烧工程的能量流动和物质循环进行了数值分析。操作堆肥厂所消耗的能量是生产蔬菜所含能量的12倍。运送垃圾和堆肥所消耗的能量是生产蔬菜所含能量的四分之一。重要的是要使一个堆肥厂的运行所消耗的能量，希望比所生产的蔬菜所含的能量要少，这样才能使堆肥垃圾所获得的物质的循环得到更多的可持续利用。在考察保温良好的堆肥池在没有辅助加热的情况下是否能充分发酵垃圾的实验中，两个堆肥池的内容物成熟度的几个指标没有差异。这证明了隔热良好的堆肥池可以在没有辅助加热的情况下充分发酵垃圾。2 .液化天然气（flng）的耗能是不保温堆肥池中垃圾耗能的六倍，而保温良好的堆肥池不需要液化天然气（lng）的耗能。在钢筋的生产过程中，消耗了83%的供能，其中包括化石燃料、原材料和水的能源，17%的供能是固定在产品内部的。在钢筋的使用中，消耗了2%的固定能量。在混凝土的生产过程中，80%的供应能源被消耗，其中包括化石燃料、原材料和水的能源，20%的供应能源被固定在产品内部。在使用混凝土时，消耗了5%的固定能量。墙体饰面类型影响墙体在使用过程中的能源消耗。消耗能量的速度较慢，顺序为：平铺、粉刷、涂漆、不涂饰。为了充分利用化石燃料和原材料，重要的是要尽可能慢地消耗固定能源。少

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
