In this present work we have studied the exergy, energy and economic performance of a V-grooved type air collector with rotating trays type of solar cabinet dryer for drying potato chips in the sunny days of winter season at Bhubaneswar (20.2961° N, 85.8245° E), Odisha. The obtained results from this experiment were also compared with the performance of a flat plate air collector with rotating trays used in the same dryer. The average energy efficiency of the solar air collector (SAC) and drying chamber (DC) was found to be 73.3% and 24.8% in case of V-grooved and 60.1% and 19.3% in case of plane collector respectively. The average exergy inflow, outflow, loss and efficiency of the drying chamber in case of V-grooved collector was found as 19.7 W, 11.82 W, 7.88 W and 58.14% where as it was 22.3 W, 12.96 W, 9.34.88 W and 56.12% in case of plane collector respectively. Similarly the average exergy inflow, outflow, loss and efficiency of the SAC in case of V-grooved was found as 845 W, 20.1 W, 824.9 W and 1.99% where as it was 830 W, 22 W, 808 W and 2.28% in case of plane collector respectively. The average exergy and energy efficiency of the V-grooved type chamber are found to be 3.47% and 22.17% higher respectively as compared to plane collector. The air temperature at the inlet and outlet of the SAC and DC mainly affects the exergy value.

在目前的工作中，我们研究了在布巴内斯瓦尔 (20.2961° N, 85.8245° E），奥里萨邦。还将从该实验中获得的结果与同一干燥器中使用的带有旋转托盘的平板集气器的性能进行了比较。太阳能集热器 (SAC) 和干燥室 (DC) 的平均能效在 V 型槽的情况下分别为 73.3% 和 24.8%，在平面集热器的情况下分别为 60.1% 和 19.3%。V 型槽收集器的干燥室平均火用流入、流出、损失和效率为 19.7 W、11.82 W、7.88 W 和 58.14%，而 22.3 W、12.96 W、9.34.88 W 和56. 平面集热器分别为 12%。类似地，发现 V 型槽情况下 SAC 的平均火用流入、流出、损失和效率为 845 W、20.1 W、824.9 W 和 1.99%，而在 V 型槽中为 830 W、22 W、808 W 和 2.28%分别是平面集热器的情况。与平面收集器相比，V 槽型室的平均火用和能源效率分别高出 3.47% 和 22.17%。SAC 和 DC 入口和出口的空气温度主要影响火用值。与平面收集器相比，V 槽型室的平均火用和能源效率分别高出 3.47% 和 22.17%。SAC 和 DC 入口和出口的空气温度主要影响火用值。与平面收集器相比，V 槽型室的平均火用和能源效率分别高出 3.47% 和 22.17%。SAC 和 DC 入口和出口的空气温度主要影响火用值。
