Cp directly influences the heat storage and heat transfer performance of materials. Despite the widespread study of Metal Organic Frameworks (MOFs), the Cp of MOF-303, known for its high water adsorption capacity; has not been previously measured. This study focuses on the measurements of Cp for MOF-303 across a temperature range of 10 °C to 95 °C and at various water vapor loadings. Using Differential Scanning Calorimetry (DSC) and Thermogravimetric Analysis (TGA), we found that the dry MOF-303 exhibited a Cp of approximately 0.9175 J/g.<sup>o</sup>C at 10 °C, increasing to around 1.1695 J/g.<sup>o</sup>C at 95 °C. In contrast, fully saturated MOF-303 samples showed higher values, with Cp ranging from 1.72 J/g.<sup>o</sup>C at 10 °C to 2.41 J/g.<sup>o</sup>C at 95 °C. These findings demonstrate that water saturation significantly enhances Cp, making MOF-303 highly efficient for adsorption cooling systems. Thermal cyclic stability tests confirm the robustness of MOF-303 under repeated heating and cooling cycles. These results provide critical insights into the thermal behavior of MOF-303 and offer a novel contribution to the field.

It is important to note that our results indicate that the structural volume decreased from 356,985 to 349,982 Å at 0.05 1/fs as the MFF increased. The alignment of polymer chains in the hydrogel was improved by increasing the MFF, resulting in a more compact structure.

US experienced a decrease from 0.0325 to 0.0331 MPa, while YM converged to 0.0008 MPa. The alignment and packaging of polymer chains improved, resulting in an increase in the US of hydrogels as the MFF increased. This enhanced alignment resulted in a material that can withstand a larger amount of stress before failing, as a result of the stronger intermolecular interactions. Additionally, the temperature coefficient (TC) increased to 0.56 W/m·K as the MFFs increased. An increase in molecular alignment and a decrease in free volume within the hydrogel can be attributed to the higher MFF.

Building on this heat transfer mechanism, this paper introduces a novel solar air collector that integrates a downward impulse jet with a corrugated absorber plate. The flow and heat transfer performance of the collector are analyzed under various flow conditions by varying parameters, such as jet hole spacing along the flow direction, spanwise spacing, sine wave amplitude, and ripple period. Based on the univariate research results, considering the influence of the interaction between different parameters on the comprehensive performance of solar air collectors, the response surface methodology is adopted to optimize the main parameters and the optimal combination of parameters has been obtained, they are <em>X/D</em> = 1.77, <em>Y/D</em> = 2.19, <em>A</em> = 1 mm, which corresponds to the maximum <em>THPP</em> value of 6.06. Compared with the collector structures with multi-arc convex ribs on the absorber plate and multiple V-arranged bumps on the absorber plate in references, the average improvement of the comprehensive heat transfer coefficient of the proposed solar air collector in this study are 20.84 % and 32.67 %, respectively. In addition, the effects of <em>Re</em> and air inlet temperature on the heat collection efficiency were studied. When <em>Re</em> changes from 6000 to 18,000, the heat collection efficiency gradually decreases with the increasing <em>Re</em>, and the average heat collection efficiency of the optimized structure is 39.4 % higher than that of the traditional flat plate. When the inlet temperature increases from 280 K to 300 K, the air outlet temperature decreases by 1.2 K, and the heat collection efficiency decreases by 5.6 %. It is concluded that the air inlet temperature has a great influence on the heat collection efficiency. The novel solar air collector structure proposed in this study, which integrates a downward jet mode with corrugated absorber plate, achieves a significant enhancement in heat transfer capacity and minimal increase in pressure drop.
