SPECTROPHOTOMETER FOR THE CHARACTERISATION OF RECEIVERS OF SOLAR COLLECTORS

摘要

Spectrophotometer for the characterisation of receivers of solar collectors in order to determine optical properties (transmittance and reflectance). The equipment allows the evaluation of a receiver tube in real time and in any kind of light conditions, both inside and outside. The equipment also allows the detection of the eccentricity between the outer tube and the inner tube, which directly influences the reliability of the measurement. The equipment has a mechanical system for allowing a rotation of the equipment around the tube in order to find the optimum measurement position and attach itself to the tube.

主权项

1. Spectrophotometer for the characterisation of receivers (1, 2) of solar collectors, said receivers comprising an inner tube (2) and an outer tube (1), the spectrophotometer being characterised in that it comprises:
(1a) a measurement module (31, 32, 6, 7) configured to take a measurement of a reflection coefficient and of a transmission coefficient of the receiver (1, 2); (1b) a concentricity detection module (8, 9) configured to detect concentricity/non-concentricity between the inner tube (2) and outer tube (1).
