Experimental analysis of heat flux distribution in triple-pane windows within a climatic chamber

An experimental study was carried out to investigate the heat flux distributionon the external surface of triple-pane windows under various conditions including: outdoor temperatures, gas filling, emissivity of the glass surfaces, and the use of electrical heating. The measurements were conducted within a controlled climatic chamber. Two window configurations were examined: one filled with air (emissivity of ε = 0.84) and the other filled with argon (emissivity of ε = 0.17). In addition, the study also assessed the impact of a local and surface electric heating on heat loss. The key contribution of this researchlies in revealing variations in the heat flux density across different parts of the external glazing of each window, specifically the lower, central, and upper regions. These findings emphasize the importance of considering the non-uniformity of thermal resistance in different areas of windows in order to accurately determine their heat transfer coefficient.
