Abstract : In this study the effect of using water glazed window and nanofluid glazed window on the thermal comfort inside a room and on the potential of obtaining hot domestic water will be investigated. To achieve this study, three identical windows were constructed and used in these work, the first one is a standard one, which will be used as a reference one for comparison purposes. The second one is a glazed one with the cavity being filled with water and a heat exchanger is inserted within this cavity through which liquid water flows and acts as a load to cool down the solar heated water in the cavity. The third window is the same as the second one but with nano fluid being flowing inside the heat exchanger. Zinc Oxide was added to pure water to form a nanofluid (0,02%, 0.04%, 0.05%,0.06%) The three windows were installed side by side and experiments were conducted simultaneously. The temperatures of ambient, inside, water and nonfluid inlet and outlet were measured on hourly basis and stored in a data logger. Also the incident solar radiation was measure. It was found that the efficiency reaches a maximum value of almost 7% that corresponds to the Nano particle concentration of 0.05%. This indicates that this concentration is the optimum one for most efficient domestic hot water production using solar window, and the inside temperature for the case of Nano fluid is the minimum one almost for all day.
