项目摘要

The purpose of this study is to develop a new calculating method for cold and hot water supply demands, such as daily, hourly, and instantaneous demands by using a personal computer.First of all, it was clarified that the actual conditions of fixture usage in a dormitory, apartments and railway station's lavatories by reexamining the previous results of study and investigation concerned with water consumption and fixture usage.Next, we carried out the investigation of water consumption and fixture usage at the other buildings, such as university cafeterias, restaurants, and office buildings in order to accumulate the new fundamental data which are applied to the calculating model. Especially, we could get valuable data not only on water consumption but also on the number of customers at the university cafeterias and restaurants where only a few fundamental data exists even now. Furthermore, we could clarify the relationship between the store characteristics and the number of customers.The calculating models contained the conditions of fixture usage were set up in each building type based on the previous studies and the results of investigation. In addition, the calculating program for cold and hot water supply demands, applied by the Monte Carlo Simulation technique, was made. As for the calculating models, two types of model were proposed. One model was set up in each fixture usage at flat, office building's restroom and railway station's lavatory. The other model was the unit model as one aggregation summed up the each fixture usage in order to apply to the buildings that have the commercial kitchens, such as university cafeterias, and restaurants.From the results of calculation in each building, it was clarified that the estimated demands were suitable by comparison with the measurement results and the calculating methods were useful for various types of buildings.

本研究的目的是开发一种新的计算方法，如使用个人计算机的冷，热水供应需求，如日，小时，瞬时需求。首先，澄清了实际情况，在宿舍，公寓和火车站的厕所，通过重新审查以前的研究和调查结果有关用水量和固定装置的使用。其次，我们在其他建筑物，如大学食堂、餐厅、办公楼等进行了用水量和设备使用情况的调查，以积累新的基础数据，应用于计算模型。特别是，我们不仅可以获得有关用水量的宝贵数据，还可以获得有关大学食堂和餐馆的客户数量的宝贵数据，即使是现在也只有很少的基本数据。在此基础上，根据以往的研究成果和调查结果，建立了各建筑类型中包含灯具使用条件的计算模型。并应用蒙特卡罗模拟技术编制了冷、热水供应量计算程序。在计算模型方面，提出了两种模型。在公寓、办公楼的洗手间和火车站的洗手间的每一个固定装置的使用中设置了一个模型。另一种模型是将各建筑物的设备使用量汇总为一个整体的单元模型，适用于大学食堂、餐厅等设有商用厨房的建筑物。通过对各建筑物的计算结果进行比较，可以确认估算的需求量与实测结果相吻合，计算方法适用于各种建筑物。
