DEVELOPMENT OF MEASURING METHOD OF THERMAL RADIATION TO A HUMAN BODY

用黑素、白素和铝素制作了6个三元型辐射通量探测器。它们的尺寸是10乘10厘米，厚3.5毫米。制作了用于传感器热导测定的校准箱。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定标室。利用该仪器测量了传感器的12个常数。用6块射频探测器制作了一个立方体Radinat通量探测器样机，该探测器由4个细长的柱子支撑。利用人体姿势对周围环境的角度系数来确定CRF探测器对人体姿势的权重因子。对四元型辐射通量探测器进行了测试，以测量燃气灶辐射等1.5微米到6.0微米的太阳辐射和长波辐射之间的介质辐射。使用三元CRF探测器进行了现场测试。在一间朝南的会议室进行的试验显示，短波辐射的数值出现异常。在一栋建筑的屋顶上进行的测试显示，太阳和长波辐射的数值超出了正常水平。这些值似乎随着空气速度的值而变化。这些事实表明，有效辐射吸收系数和有效太阳吸收系数都需要重新校准。在没有实验的情况下，从理论上设计了一种新的空气速度修正系数的校准方法。重新校准的结果有了显著的改善。

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.
