DEVELOPMENT OF MEASURING METHOD OF THERMAL RADIATION TO A HUMAN BODY

用黑色元件、白色元件和铝元件制造了六件三元件型辐射通量探测器。它们长10厘米宽10厘米，厚3.5毫米。制作了传感器热导率的标定箱。并制作了有效辐射吸收率、风速修正系数和有效太阳吸收率的标定箱。使用这些装置，确定了传感器的总共12个常数。使用六个RF检测器制造了立方体Radinat通量检测器的原型，该探测器由四根细柱支撑。人体姿势的CRF探测器的权重因子是通过使用人体姿势与周围环境的角度因子来确定的。四元素型辐射通量探测器被检验用于测量中等辐射，燃气灶辐射的辐射强度介于太阳辐射和长波辐射之间，为1.5 ~ 6.0 μ m。在一个朝南的会议室里进行的试验显示，短波辐射值异常。在一座建筑物的屋顶进行的试验显示，太阳辐射和长波辐射的数值与正常值不同。这些值似乎根据空气速度的值而变化。提出了一种新的风速修正系数的标定方法。重新校准后的结果得到了显著改善。

Six pieces of the Radiant Flux Detector of three elements type were manufactured with black element, white element and aluminum element. They measure 10 by 10 centimeters and 3.5 milimeters in thick. A calibration box for determination of thermal conductance of the sensor was made. A chamber to calibrate the effective radiation absorptance, the revised coefficient for air velocity and the effective solar absorptance was made, too. Using these apparatus, total 12 constants for a sensor were determined.A prototype of the Cubic Radinat Flux Detector was manufactured using six pieces of the RF Detector, which ws supported by four slim posts.Weighting factors of the CRF Detector for a human posture were determined by using angle factors on a human posture to the surroundings.The Radiant Flux Detector of four elements type was examined to measure medium radiation such as gas stove radiation, 1.5 micrometers to 6.0 micrometers, between solar radiation and long wave radiation.Field test was carrid out using the CRF Detector of three elements type. A trial in a seminar room faced to the south showed abnormal values in short wave radiation. A trial at the roof top of a building showed values apart from normal in solar and long wave radiation. The values seemed to change according to values of air velocity. Those facts suggested recalibration of both the effective radiation absorptance and the effective solar absorptance.A new calibration method for the revised coefficient for air velocity was devised theoretically without experiment. Recalibrated results were remarkably improved.
