This study aims to arrange the technical guidelines for mechanical central ventilation systems suitable for air-tightened houses. In this paper, we called 2kinds of mechanical ventilation systems the duct system and the forced exhaust system respectively. With the duct system, supply fresh outdoor air is carried to each room with supply duct and forced fan, besides exhaust air from each room is flowed to a corridor through under-cut opening of door and is sucked to the mechanical ventilation unit. With forced exhaust system, exhaust air is sucked from a bathroom or a wash room and the pressure difference makes outdoor fresh air come in the room through a inlet installed on extemal wall.Results of full scale experiments to clarify the relations among the air-tightness of apartment houses, weather conditions, infiltration air volume and ventilation rate, sugested that higher technical level for air-tightness is required in order to work the forced exhaust system perfectly. The duct syste … More m is recommended for any air-tightened houses.Air flow resistance coefficients of under-cut opening of door, fresh air inlet installed on external wall, ventilation grille, door grille of bathroom, fusuma (Japanese traditional fitting) and so on, through which air flow path is made with mechanical ventilation systems, are measured and data base of input for simulation program analyzing air flow conditions with mechanical central ventilation systems are prepared.Simulation program analyzing air flow conditions with mechanical central ventilation systems are developed and verified. Various factors related with the mechanical central ventilation systems are checked by this simulation program. For example, pressure difference induced by temperature difference induce indoor air to go out through the openings located at the first floor level and outdoor air to flow in through the openings located at ground level in winter. Such air flow condition is not proper. Corrected height of opening at the first level improve air flow pattem. Forced supply and exhaust ventilation systems for kitchen ventilation and bathroom ventilation are recognized not to disturb the air flow path. Many technical data are summarized to the technical guidelines. Less

这项研究旨在安排适合气密房屋的机械中央通风系统的技术指南。在本文中，我们将机械通气系统的2kinds分别为导管系统和强制排气系统。使用管道系统，供应新鲜的户外空气被带到每个房间，并带有供应管和强迫风扇，除了每个房间的排气空气外，还通过门开口开口到走廊，然后被吸吮到机械通风单元。借助强迫排气系统，排气空气被从浴室或洗涤室里吸走，压力差使室外新鲜空气通过安装在外墙上的入口进入房间。全面实验的重新阐明了公寓房屋，天气状况，天气状况，浸润空气和通风率的空气状态之间的关系，以确保较高的技术水平，以使空气紧密地进行排量的排放系统。 The duct syste … More m is recommended for any air-tightened houses.Air flow resistance coefficients of under-cut opening of door, fresh air inlet installed on external wall, ventilation grille, door grille of bathroom, fusuma (Japanese traditional fitting) and so on, through which air flow path is made with mechanical ventilation systems, are measured and data base of input for simulation program analyzed air flow conditions with mechanical central ventilation systems are制备的。制定计划通过机械中央通风系统分析的空气流条件进行了开发和验证。该模拟程序检查了与机械中央通风系统有关的各种因素。例如，温度差引起的压力差会导致室内空气穿过位于一楼的开口，并在冬季的地面上的开口流入室外空气。这样的气流条件不合适。在第一级开口的校正高度改善了空气流量。厨房通风和浴室通风的强制供应和排气通风系统被认为不干扰空气流道。许多技术数据总结为技术指南。较少的
