Thermodynamic Analysis of Heating with Solar Assisted 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 heating season of solar assisted vertical type ground source heat pump integrated with fan coil system. Solar energy is used with the aim of sustaining the heat pump system. Instant data records were taken in the heating process (01.10.2013 / 31.03.2014) for the 14 node points determined in the installed system. In the analysis of experimental data through immediate data recording, the COP value of the system was 3.61, the energy loss was 8.9952 kW, the loss of exergy was 6.2673 kW, the energy efficiency was 64.52% and the second law efficiency was 24.51%. In the heating season, solar energy's rate of meeting energy need of the heat pump system was found to be 9.75%. The elements with the most loss of exergy in the system are designated as collectors and compressors. 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 system examined for Mardin Province is appropriate.
