项目摘要

Generally, to make the heat environment which doesn't have a temporal change and spatial distribution is the goal of the air-conditioning. Then, however, that there is a limit to attempt energy saving while keeping thermal comfort is definite. Therefore, it examined the air-conditioning method which the energy saving and the comfort are compatible with in using a temporal change and spatial distribution aggressively. Specifically, it experimented for the effect of the change with temporal wind velocity. Based on the result of the experiment, it examined respectively about the physical, physiological and psychological influence of the change of the wind velocity.First, it did the experiment which used the model of the circular cylinder type to have imitated a human body to clarify an influence with physical change wind. As a result, it found a thing below.1)At the average wind velocity of 0.65 m/s, as for the convective heat transfer coefficient, the case of the equal to or more than 0.1 Hz wind velocity change is bigger than the case of constant air movement.2)The convective heat transfer coefficient with 40 % of turbulent intensity is bigger than the coefficient with 15 %. Also, the increasing tendency becomes big when making a frequency low.3)When the frequency becomes low, convective heat transfer coefficient approaches a value with the constant air movement.Next, it got following result from the experiment which examines the physical, physiological and psychological influence of the fluctuating air movement by subjects.4)The convective heat transfer coefficient to the constant air movement gets to be near the value of Mitchell.5)The convective heat transfer coefficient to the fluctuating air movement becomes bigger than the value to the constant air movement.6)Relation between the voting ratio of hot or warm and average body temperature was shown.

通常，使没有时间变化和空间分布的热环境是空调的目标。但是，但是，在保持热舒适度的同时尝试节省能源是有限的。因此，它检查了节能和舒适度与时间变化和空间分布的积极分配相兼容的空调方法。具体而言，它通过时间风速进行了实验，以实现变化的影响。根据实验的结果，它分别研究了风速变化的物理，生理和心理影响。首先，它进行了使用圆形圆柱体类型模型的实验，以模仿人体，以阐明物理变化风的影响。结果，它发现了以下的东西。1）在平均风速为0.65 m/s的情况下，至于对流传热系数，其情况等于或大于0.1 Hz风速变化的情况大于恒定空气移动的情况。2）对流热传递系数，速度高于湍流的40％，均超过15％的湍流。同样，在使频率降低时，日益增加的趋势变得很大。3）当频率变得较低时，对流传热系数与恒定空气移动的价值接近价值。接头，它遵循了实验，该实验遵循了实验的结果，该实验检查了对受试者的自动运动的物理，生理和心理影响，受试者通过受试者的空气移动的动作。4）4）对有效的空气移动到恒定的传热范围，使得恒定的空气转移。运动变得比恒定空气运动的价值更大。6）显示了热或温暖和平均体温的投票比例之间的关系。
