Nowadays, the effective and efficient use of energy has become an indispensable necessity due to energy sources gradually are decreasing and energy prices are increasing. In this study the experimental results of vertical type ground source heat pump pump for cooling seasons for a test site which is 120 m2 experimental ground area in Midyat/Mardin. After examining the results of studies energy, exergy and eksergo economic analysis was performed over the system. According to the analysis of the system it was determined that the compressor cooling process is of 3,704 kW best heat loss, 1.6539 kW the highest exergy loss, 0.4658 $/h and cost rate associated with capital investment, 0.7464 $/h and the high cost of exergy, exergy loss 44,72% rate of 38.43% and values eksergo economic factors. For this reason, it is inevitable that the planned improvements should be carried out primarily compressor. As a result; our system is quite effective in both reduce energy consumption and reducing greenhouse gas emissions.
