Thermodynamic Analysis of Cooling with Vertical Type Ground Source Heat Pump: Mardin Case Study

Abstract

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.
