In this study, a vertical ground source heat pump wall cooling system that belongs to the Yildiz Renewable Energy House at the Davutpasa Campus of Yildiz Technical University was studied both experimentally and theoretically. The principal objective was to perform a system analysis to determine the parameters that allow the energy usage of the cooling system to be as low as possible. For this reason, a system working in a low temperature regime was chosen. The examination includes energy and exergy analyses conducted during the period between 1 July and 30 September 2012, which is described as the "Summer Session". By using the data that were collected on a per-second basis during these processes and conveyed to a MySQL database, "The moments when the heat pump is activated" were detected, and the "Monthly Average Values" were analyzed. Thus, a theoretical analysis was conducted for the Cooling Session and its correlations. These correlations were used in the energy and exergy analyses. According to the analysis results, the energy and exergy efficiencies of the entire system were found to be 74.85% and 29.90%, respectively, and the Wall Heating Cooling System panels calculated the heat with energy and exergy efficiencies of 90.29% and 80.4%, respectively.
