The invention aims to provide a testing system and a method for a glass transmission solar radiation. The testing system comprises a to-be-tested glass, a first aluminum plate, a second aluminum plate, an electric heating film and a baffle. The first surface of the first aluminum plate is coated with a black paint and placed under the to-be-tested glass, so that the first surface of the first aluminum plate absorbs a solar radiation passing through the to-be-tested glass. The baffle is an opaque paperboard, and is used for blocking the first surface of the second aluminum plate from absorbingthe solar radiation. The first surface of the second aluminum plate is coated with a black paint and placed behind the baffle. The electric heating film is placed on the first surface of the second aluminum plate, and is used for heating the second aluminum plate. The quantity of the solar radiation is obtained according to a heating power, an indoor air temperature and a surrounding environment temperature, wherein the heating power is a power required when heating the second aluminum plate to the same temperature as the first aluminum plate, so that the measurement error caused by the agingof circuits and components inside the measurement radiation meter is avoided.
Description
technical field [0001] The present application relates to the testing field of solar radiation absorption, in particular to a testing system and method for glass transmission of solar radiation. Background technique [0002] At present, electronic instruments are usually used to measure solar radiation, and the instrument may cause changes in measurement characteristics due to material aging, changes in the use or storage environment, and handling. Measuring the integrated circuits inside the pyranometer and the internal components of the integrated amplifier Aging will cause measurement errors, and some measuring pyranometers are inconvenient to carry and use. Contents of the invention [0003] The purpose of this application is to provide a test system and method for glass transmission of solar radiation to solve the problem of measurement errors caused by the aging of the integrated circuit inside the pyranometer and the internal components of the integrated amplifier. ...
