The present invention relates to a heat collection efficiency measurement method for quantitatively measuring the absolute value of heat collection efficiency in a receiver.
そこで、本発明は上記課題を解決するものであって、太陽熱利用システムのレシーバにおける集熱効率の絶対値を定量的に測定する際に用いる擬似太陽光照射装置と、この擬似太陽光照射装置を利用した集熱効率測定方法を提供することを目的とする。 Therefore, the present invention solves the above-described problem, and uses a simulated solar irradiation device used when quantitatively measuring the absolute value of the heat collection efficiency in a receiver of a solar heat utilization system, and the simulated solar irradiation device. An object of the present invention is to provide a method for measuring heat collection efficiency .
さらに、太陽熱利用システムで使用される円筒形のレシーバにおける集熱効率を測定する集熱効率測定方法であって、上記擬似太陽光照射装置により前記レシーバへ擬似太陽光を照射して前記レシーバ内部に流通させた流体の温度上昇から算出される回収熱量（出力エネルギー）と、下記光照射強度分布測定装置によって測定された光照射強度分布（入力エネルギー）との比（出力エネルギー／入力エネルギー）により、集熱効率の絶対値を定量測定する、集熱効率測定方法を提供することもできる。
そして集熱効率測定方法に用いられる光照射強度分布測定装置は、太陽熱利用システムで使用される円筒形のレシーバにおける集熱効率を測定する際に用いられる擬似太陽光源から照射された光の照射強度分布を測定するための光照射強度分布測定装置であって、光照射強度を検知するセンサと、前記センサを前記レシーバの軸方向にスライド移動させるスライド機構と、回転軸を中心として前記センサを前記レシーバの周方向に軸回転させる回転機構とを備え、前記回転軸から前記センサの受光部までの距離が、前記レシーバの中心軸から周壁外面までの距離と同じであり、前記回転軸が前記レシーバの中心軸と同軸上にセットされる構成である。
Furthermore, it is a heat collection efficiency measurement method for measuring heat collection efficiency in a cylindrical receiver used in a solar heat utilization system, wherein the simulated sunlight irradiation device irradiates the receiver with simulated sunlight and distributes it inside the receiver. and a quantity of heat recovered is calculated from the temperature rise of the fluid (output energy), the ratio between the measured irradiation intensity distribution by the following light irradiation intensity distribution measuring device (input energy) (output energy / input energy), heat collection efficiency It is also possible to provide a heat collection efficiency measuring method for quantitatively measuring the absolute value of.
And the light irradiation intensity distribution measuring device used in the heat collection efficiency measurement method is the irradiation intensity distribution of the light emitted from the pseudo solar light source used when measuring the heat collection efficiency in the cylindrical receiver used in the solar heat utilization system. A light irradiation intensity distribution measuring device for measuring, a sensor for detecting light irradiation intensity, a slide mechanism for sliding the sensor in the axial direction of the receiver, and the sensor around the rotation axis of the receiver A rotation mechanism that rotates the shaft in a circumferential direction, a distance from the rotation shaft to the light receiving portion of the sensor is the same as a distance from a central axis of the receiver to an outer surface of the peripheral wall, and the rotation shaft is a center of the receiver The configuration is set coaxially with the shaft.
本発明の集熱効率測定方法に用いられる光照射強度分布測定装置は、太陽熱利用システムにレシーバが設置されている状態を想定しながら、この仮想レシーバに対する擬似太陽光源からの擬似太陽光の照射強度を測定するものであって、レシーバに替えて擬似太陽光照射装置に組み込んで使用されるものである。そのうえで、当該光照射強度分布測定装置は、センサを左右にスライド移動させるスライド機構を有するので、仮想レシーバの軸方向の両端に亘って全範囲の光照射強度を測定することができる。同時に、センサを軸回転させる回転機構を備えることで、仮想レシーバにおける周方向の光照射強度分布も測定することができる。加えて、回転軸からセンサの受光部までの距離が、レシーバの中心軸から周壁外面までの距離と同じであるため、センサ受光部は仮想レシーバの周壁に沿って回転するので、レシーバにおける光照射強度分布を正確に測定することができる。

It is to be measured and used by being incorporated in a simulated solar light irradiation device instead of a receiver. In addition, since the light irradiation intensity distribution measuring apparatus has a slide mechanism that slides the sensor to the left and right, the light irradiation intensity in the entire range can be measured across both ends of the virtual receiver in the axial direction. At the same time, the light irradiation intensity distribution in the circumferential direction in the virtual receiver can be measured by providing a rotation mechanism for rotating the sensor shaft. In addition, since the distance from the rotation axis to the light receiving part of the sensor is the same as the distance from the central axis of the receiver to the outer surface of the peripheral wall, the sensor light receiving part rotates along the peripheral wall of the virtual receiver. The intensity distribution can be accurately measured.
