Light spot energy measuring system and method suitable for solar disc light condensation

Abstract

The invention discloses a light spot energy measuring system and a method suitable for solar disc light condensation. The system comprises a cavity heat absorber; an inner cavity of the cavity heat absorber is a light absorbing area provided with a cooling water runner; an opening capable of emitting incident light into the inner cavity is formed in the cavity of the cavity heat absorber; a water inlet of the cooling water runner is connected with a cooling water supply system through a pipe; a water outlet of the cooling water runner is connected with a cooling water recovery system through a pipe; the cooling water supply system is provided with a first pressure measuring element, a temperature measuring element and a mass and flow measuring device for measuring supplied water; and the cooling water recovery system is provided with a second pressure measuring element and a temperature measuring element for measuring recovered water. The system fills the blank of the field; and no matter heat utilization of a disc light condenser or solar energy, the energy values of light spots are key parameters.

Description

technical field [0001] The invention belongs to the technical field of solar heat utilization, and relates to spot energy measurement, in particular to a spot energy measurement system and method suitable for solar dish-type concentrated light. Background technique [0002] At present, the measurement of spot energy is mostly carried out by CCD camera or irradiance sensor. CCD camera is not only costly, but also difficult to protect from heat, which is easy to cause damage to the camera. And this measurement method is to get the camera under a certain condition. The color spot image is processed as a whole, ignoring the difference between the image captured by the camera under different parameters, and the difference between the red, green and blue component data of the image under the same parameter, which will make the analysis results uncertain; The irradiance sensor also has the problems of difficult thermal protection and easy damage, and the range of energy measured is...
