Research and Development (R & D)


  • Students working in the RTC have developed new absorber shapes of the FPC of less than 100 LPD capacity by the following manner:
    • Single continuous rectangular absorber duct of size 1.96m x 0.96m x 0.01 m replacing copper riser tubes having a direct heat transfer between top absorber sheet and the fluid.
    • Four parallel rectangular absorber duct of size 1m x 0.85m x 0.012m replacing copper riser tubes having a direct heat transfer between top absorber sheet and the fluid as shown below-
    • Riser Tubes replaced with Wavy Continuous Duct

  • Students indigenously developed a storage collector for 100 LPD water heater by the following manner-
    • Riser tubes have been replaced with a wavy continuous duct for more heat absorption. It is shown below-
    • Riser Tubes replaced with Wavy Continuous Duct
