(Springer, 2018) Ünal, Fatih; Temir, Galip; Köten, Hasan; 17.05. Department of Machine and Metal Technologies / Makine ve Metal Teknolojileri Bölümü; 17. Vocational Higher School / Meslek Yüksekokulu; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
The purpose of this study is to evaluate the experimental performance of a solar assisted vertical ground source heat pump system (VGSHP) for the winter climatic conditions of Mardin, which is in the South-Eastern Anatolia region of Turkey. For this aim, an experimental analysis was performed on solar assisted VGSHP system, which was designed to meet the heating needs of an experimental room, during the heating season (10.01.2013/03.31.2014). The experimentally obtained results were used to calculate energy, exergy and exergoeconomic analyses of the system and its components. The energy efficiency, exergy efficiency and exergoeconomic factors of the entire system were 67.36 %, 27.40 % and 60.51 %, respectively. In this study, the system was proposed for disseminating the use of alternative technologies supported by renewable energy systems and it has been tested for the first time in Mardin to meet its heating needs with convectional systems. The experimental results showed that the proposed solar assisted VGSHP system can be used for residential heating in Mardin and similar regions. As a result, it has been detected that the system is very effective in both reducing energy consumption and decreasing emissions of green-house gases.

Exergo Economic Analysis of the Ground Source Heat Pump for Cooling Seasons in the Mardin Province
(Yildiz Technical Univ, 2014) Unal, Fatih; Ünal, Fatih; Temir, 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 m(2) 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.
