Experimental Performance Analysis of Ground Source Heat Pumps (GSHPs) in Taleghan-Iran

Abstract

Ground Source Heat Pumps (GSHP) have become as one of the most indispensable cooling and heating systems in residential applications since they have higher energy efficiency compared to the other conventional alternatives all around the world. In this study, a ground source heat pump system (GSHP) with the heat package unit model of GT018 FHP Manufacturing Co was installed in Taleghan city-Iran. The system set-up included polyethylene U-bend ground heat exchanger pipes, 9 drilled wells, and the pipes buried in soil at 15 m depth and in the cooling season of 2013. The system was tested and its performance was reported. In accordance with the meteorological data, the values of humidity variations, air temperature, wells and water temperatures, relative humidity and the system power supply were measured continuously for three months. The results showed that the adoption of GSHP system created a stable room indoor temperature of 25° C to 28° C. Furthermore a great energy saving happened in the process and the average COP of 4.76 was achieved for the system that shows a suitable design and installation process
