Objective:
To experimentally investigate the thermal performance of solar water heater by heat enhancer The objective of this research work to increase the instantaneous collector efficiency and the economic analysis of solar water heater.
Method:
To expand the regime availability of solar water heater, a minimum operating cost solar water collector is fabricated and is experimentally analyzed in Solan, Himachal Pradesh, India. In this solar water heater, the absorber tubes are made up of copper providing glazing on the top surface. An experimental is performed to analyze the influence of distinct parameters of the hindrance promoter on heat transfer of Solar water heater (SWH). The SWH is provided by the hindrance promoter with repeated winglet imposed on both side copper strips. Testing is carried out in the three main season’s summer, winter and rainy seasons.
Result:
The result shows that the instantaneous efficiency of the collector by inserting the hindrance promoter is found to be 81%.
Conclusion:
The average temperature of the 50l tank of water collected each day in the rainy, winter and summer season are, 60 ˚C, 52 ˚C and 65 ˚C respectively. Furthermore, to see the specific effect on the outlet water temperature of the SWH system a delta winglet is introduced into the absorber tube and compare with the smooth tube outlet temperature. The instantaneous efficiency of the collector by inserting the hindrance promoter is found to be 81.5%. Also, a detailed study on the economic analysis and the payback period is also investigated in this paper.
