    EXERGO ECONOMIC ANALYSIS OF THE GROUND SOURCE HEAT PUMP FOR COOLING SEASONS IN THE MARDIN PROVINCE
    (Yıldız Technical University, 2014-04-05) ÜNAL, Fatih; TEMİR, Galip
    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.

    Thermodynamic Analysis of Cooling with Vertical Type Ground Source Heat Pump: Mardin Case Study
    (International Knowledge Sharing Platform, 2017-02-20) ÜNAL, Fatih; TEMİR, Galip
    In this study, for experimental area with a ground area of 120 m2 determined in district Midyat of province Mardin in the hot climate zone of Turkey, analysis of energy and exergy are applied to the system by investigating the results of experimental studies for the cooling season of vertical type ground source heat pump integrated with fan coil system. Instant data records were taken in the cooling process (01.07.2013 / 31.10.2013) for the 11 node points determined in the installed system. In the analysis of experimental data through immediate data recording, the COP value of the system was 3.70, the energy loss was 3,125 kW, the loss of exergy was 3,698 kW, the energy efficiency was 83.88% and the second law efficiency was 21.31%. In the cooling season, the element that works with the least energy efficiency in the system and the loss of highest exergy is designated as compressor. In this context, it has been determined that priority should be given to compressor for improvement studies to be considered. As a result, it has been determined that the use of vertical type ground source heat pump system for cooling purposes is suitable for Mardin Province.
