<p>The present invention relates to a multistage combined device comprising many convex lens condensing members for absorbing solar energy designed for industrial and civil application where need to control liquid or gas temperature. The sun's rays focus on the tube's walls to produce enormous energy absorbed by the liquid in the tube. When ray's intensity becomes weakly, liquid temperature is controlled by regulating liquid flowrate by computer or controlling the alternating electric field intensity between two electrode plates in the solar energy absorber in order to supplement energy. The combination of the device and parts of an absorption air-conditioner enable the solar and electric energy to have complementarity.</p> |
