Both collectors have equal dimensions and panels with the same features are placed inside. A zigzag strip is placed within the cavities of the collec-tor I panel. The inside of the cavities of the collector II panel is left empty. The thermal efficiency of the panel was observed by providing air flow from the bottom of both collectors. A good design is essential for an efficient collector. As a result of the studies carried out, according to the second law of thermodynamics, the efficiency of collector I, which has a zigzag inside the panel, is between 20.2% and 38.8%, whereas the efficiency of collector II, which is hollow inside the panel, varies between 17% and 32.2%.}, title={Experimental investigation of inside zigzag pipe collector solar air heaters: energy and exergy analyses}, type={Article}, URL={http://journals.pan.pl/Content/133420/20_AoT_4-2024_Kaya_593.pdf}, doi={10.24425/ather.2024.152011}, keywords={air heating, First law of thermodynamics, Second law of thermodynamics, Exergy, Collector effi-ciency}, }
