项目摘要

This study aims at developing evaluation method of recently built air-tight houses concerning 1)air exchange characteristics in each room based on tracer gas experiment, 2)cross-ventilation characteristics and 3)effect of air-tightness and outdoor wind condition on installed ventilation equipments. As for the first purpose, we performed feasible study using full-sized model house and found that accurate evaluation of steady state tracer gas concentration in each room as well as inter-room flow rates is capable if pulse injection of tracer gas is made at an interval of 30 minutes. This method was then successfully applied to a collective house of super high-rise building for the quick evaluation of steady state concentration distribution and inter-room air exchange rates. As for the evaluation of cross-ventilation characteristics, we performed on site experiment using a collective house of middle story building, and found that tracer gas concentration of downstream rooms and downstream … More windows becomes almost uniform. However, temporal variations of room concentration does not well coincide with the solution of differential equation assuming each room air is completely mixed. Further work is needed concerning the injection method of tracer gas and mixing method of room air. A New trial research is then started to utilize on site pressure measurement and wind tunnel experiment. As for the last purpose of estimation of relationship between ventilation system, and air-tightness and outdoor wind condition, a number of field measurement was carried out of the air leakage areas of super-high-rise apartment houses located in urban area. It was found that air leakage area of doors is significantly different among the houses, and it can affect decisive influence of over all air-tightness and air exchange characteristics of the houses. Based on the measurement, an evaluation method of ventilation performance of equipment installed at center-core type super-high-rise apartment houses is developed using wind tunnel test data, climate data and air-tightness data of the building.

本研究的目的在于发展一种新的气密性住宅的评估方法，包括：1）基于示踪气体实验的每个房间的空气交换特性; 2）交叉通风特性; 3）气密性和室外风条件对安装的通风设备的影响。关于第一个目的，我们使用全尺寸的模型房屋进行了可行性研究，发现如果以30分钟的间隔进行示踪气体的脉冲注入，则能够准确评估每个房间中的稳态示踪气体浓度以及房间间的流量。并将该方法成功应用于某超高层建筑集体住宅的稳态浓度分布和室内换气率的快速评价。对于交叉通风特性的评价，我们利用一栋中层建筑的集体住宅进行了现场实验，发现下游房间和下游房间的示踪气体浓度 ...更多信息 Windows几乎是统一的。然而，室内浓度的时间变化并不完全符合微分方程的解决方案，假设每个房间的空气完全混合。示踪气体的注入方法和室内空气的混合方法有待进一步研究。利用现场测压和风洞试验进行了新的试验研究。最后，为了评价通风系统与气密性及室外风况的关系，对城市超高层住宅的漏风面积进行了现场测量。结果表明，不同类型住宅的门的漏风面积有很大差异，它对住宅的整体气密性和换气性能有决定性影响。在此基础上，提出了利用风洞试验数据、气候数据和建筑物气密性数据对中高层住宅通风设备性能进行评价的方法。少
