Abstract
Space and weight constraints, as well as the time lag between energy generation and consumption, are major obstacles to expanding solar water heating systems into existing structures with limited space. It is possible to collect heat with this small, evacuated tube collector (ETC). It was found that the air inside the glass tube has poor thermal conductivity. An experimental and numerical study was performed on an evacuated tube solar collector, incorporating a heat tube with cylindrical fins to increase the contact surface between the air and the fin surface. Statistical analysis software is used to verify the results in practice. The temperature data was investigated using SPSS under the same flow conditions. These figures are from experiments examining the effect of variable volumetric flow rate, boost type, and variance analysis on temperature distribution. When analyzing the results of the trials, a significant threshold of 95% was used. Therefore, we compare the calculated significance to a value of 0.05 to evaluate the efficacy and capabilities of the components. The reliability and validity of the model depend on the presence of two components. If the resulting value is less than the significance level (0.05), then the model can be considered robust and efficient (flow rate and optimization type). If the estimated value is greater than that, the variables do not affect system performance. Flow rate and type of enhancement are the two factors considered in the analysis of variance.
