    • PROBLEM TO BE SOLVED: To solve a problem of irregularity in determination precision generated due to quantity of cloud or the like in a conventional solar radiation sensor in which an elevation angle to the sun is directly determined based on output of a light receiving element.
      SOLUTION: In this solar radiation sensor 1, the elevation angle AEi to the sun and solar radiation quantity PSi computed based on the output of the light receiving element 3 are compared with a solar radiation quantity data table PST for fine weather to determine a degree of fine weather RC. A correction value based on a correction coefficient corresponding to the degree of fine weather RC is deducted from the output of the light receiving element. An azimuth and the elevation angle to the sun are computed again to the values after deduction. Quantity of diffusing light included in a received solar beam is predicted as a coefficient of quantity of cloud, and diffusing light is deducted from quantity of light received by the light receiving element. Components of direct solar radiation are thus obtained to be recomputed. The elevation angle to the sun of such high precision that is extremely close to a real value can thus be obtained.

    • 要解决的问题:为了解决常规太阳辐射传感器中由于云量等而产生的确定精度不均匀的问题,其中基于光接收元件的输出直接确定与太阳的仰角。 解决方案:在该太阳辐射传感器1中,将基于光接收元件3的输出计算出的太阳仰角和太阳辐射量PSi与太阳辐射量数据表PST进行比较,以确定天气的程度 好天气RC。 从光接收元件的输出中扣除与微小程度RC对应的修正系数的修正值。 方位角和与太阳的仰角再次计算为扣除后的值。 包含在接收的太阳光束中的漫射光的数量被预测为云的数量系数,并且从由光接收元件接收的光量中减去漫射光。 因此获得直接太阳辐射的成分被重新计算。 因此可以获得非常接近真实值的如此高精度的与太阳的仰角。

    • PROBLEM TO BE SOLVED: To solve the problem that a printed circuit board mounting a light receiving element is set as size reference when the board is fixed to a base, in the conventional solar radiation sensor, so that measurement precision is decreased by levitation of the element from the board.
      SOLUTION: This solar radiation sensor 1 consists of the light receiving element 2 fixed on the printed circuit board 3, a condenser lens 4, and a base 5 which holds the element 2 and the lens 4 while maintaining a prescribed interval. In the board 3, through holes 3a are formed corresponding to a position where the element 2 is fixed. In the base 5, positioning bosses 5d are formed which are fitted into the respective through holes 3a, abut against the rear of the element 2, and set an interval between the element 2 and the lens 4. The positioning bosses are made to abut against the light receiving element itself, and positioning is performed to the base, thereby solving the problem.

    • PROBLEM TO BE SOLVED: To solve the problem that an error at the time of controlling an air conditioner is large since the variation of the characteristics of solar radiation sensors is large due to inter-light receiving element arrangement error or the assembly error of a light receiving element holder and a condensing lens or the like in this conventional solar radiation sensor.
      SOLUTION: In this solar radiation sensor 1, a light receiving element holder 3 where light receiving elements 2 are arranged and a condensing lens 4 are provided with a freely sliding face 3a with which they are brought into contact on the face orthogonal to an optical axis. Also, a reference light source 10 is arranged in the optical axial direction of the condensing lens 4, and the condensing lens 4 or the light receiving element holder 3 are allowed to slide along the sliding face 3a so that outputs from the light receiving elements 2 can be made equal with respect to a light from the refence light source. When the output difference is reduced as much as possible, the output adjusting method of the solar radiation sensor constituted by fixing the condensing lens and the light receiving element holder is executed so that the variation of the solar radiation sensors 1 can be reduced.
