A solar energy collectors of heating the air

Of a placement at the roof of a building using solar collectors to heating the air thermal properties were studied. Introduction a unit of the air flowing through the solar radiation collector temperature rise that characterized the parameters of a combination of collector, through measuring the thermal performance of the relevant factors of collector, such as outlet temperature, export air speed and solar radiation intensity under different conditions at the transition season, the affect of outdoor air temperature with solar radiation intensity and changes of the solar collector temperature rise with the export air speed and solar radiation effects have been explored. Experiments obtained the rule of the outdoor air temperature delayed action and continuity as solar heating during the test of local solar radiation intensity, given the changes trend of solar collector temperature rise with air speed and recommend the use of a reasonable collector temperature rise range.
