SOLAR EXPERIMENTAL STAND

for realization of tests of polymeric solar collectors

The stand is created in 2009 for study of the working characteristics of new generation of polymeric solar collectors. These SC are based on use multichannel of polymeric structures and differ from let out in the world flat solar collectors SC in cost and weight, and also considerably reduced anthropogenesis influence on an environment.

Polymeric solar collectors SC are intended for creation of systems of hot water supply, solar refrigerating systems SRS and solar systems of an air conditioning SSAC.

The stand is intended for performance of scientific researches and practical employment on specialities ‘Alternative power ’.

For experimental study (test of experimental samples) thermal characteristics of solar collectors CK the stand was created, which circuit is submitted in figure. The stand is symmetric and includes two completely similar of a contour for reception of the comparative working characteristics of samples SC. Each contour, in turn, includes: the water pipeline equipped with the gate, which is connected to the accumulator of heat in volume 100 litres everyone; two pipelines, which serve connection of heat with researched SC.

To the measuring device the thermocouples on an input in a collector, on an output from it and thermocouple fixing temperature of an environment are connected. In everyone of heat is established (completely identically on an arrangement) till seven thermocouples (six on height of water in a tank, on its axial line, and one between a wall of a tank and thermal isolation). For measurement of intensity of solar radiation the special device piranometry was used. For measurement of speed of a wind was used anemometry.

The stand allows to compare the characteristics of job two various SC in natural conditions, at solar radiation and weather conditions, as they would work in structure of real solar system.
