Propose a new technique for General Commissioning of ventilation system in house and development of planning and assessment tools for Commissioning

本研究旨在为住宅通风系统的综合调试(性能验证)提供一种新的技术，以达到节能、预防病态住宅综合症的目的。这项研究是为了开发调试所必需的运行支持和评估工具而实施的。根据修订后的日本建筑标准，有义务在房屋中安装机械通风设施，并绘制规划阶段的数字报表。针对常规调试技术，根据规划、安装和运行阶段性能验证的假设，研究了各阶段的评估方法，作为规划评估工具开发的通风规划模拟工具，能够方便地通过替换洞口来估算通风量。在需要进行必要的详细分析的情况下，开发了一种混合技术。该技术可以利用COMIS计算节点间的通风率，并通过CFD进行宏观和微观分析来计算房间内的气流。对于安装和运行阶段的测量方法，我们对实际房屋和实验房屋进行了测量和数值分析。并从项目、设备、测量周期、使用条件、房主负荷等方面分析了满足房型、通风系统、房况等测量条件的选择和使用方法，最后对实际房屋通风系统的总体调试情况进行了检验。调试费用和调试工程师的培训费用是影响住宅通风系统普遍调试的关键。

This research is to propose a new technique for General Commissioning (performance verification) of house ventilation system based on the purpose of energy saving and preventing sick house syndrome. And this research was implemented for the development of operation support and assessment tools that are essential for Commissioning.It is obliged to install mechanical ventilation facilities in houses and draw out a numeric statement of the planning stage by the revised Japanese Building Standard. However it was revealed that the air flow rate of ventilation system was below the requirement of 0.5 ACH in many existing houses.For the General Commissioning technique, the assessment method of each stage was studied according to the assumption of the performance verification of planning, installation and operation stages.The ventilation planning simulation tool developed as the assessment tool of planning is able to estimate the ventilation rate easily by substituting openings. In the case which requires essential detailed analysis, a hybrid technique was developed. This technique can calculate ventilation rate between nodes using COMIS and air flow in the room by CFD for Macro and Micro analysis.For the measurement method of installation and operation stages, we operated the examination of measurement and numerical analysis for the actual and experimental houses. And we analyzed the selected and application method to meet the measurement conditions such as types of house and ventilation system and situation of house, in terms of items, equipments, periods of measurement, application condition and load of the house owners.Finally the General Commissioning of the ventilation systems of the actual houses was examined. The cost for the Commissioning and the training of the Commissioning Engineers is the key to the prevalence of the General Commissioning of the house ventilation system.
