Energy Efficiency Analysis and Evaluation of GSHP in Operation

Abstract Ground Source Heat Pump (hereinafter referred to as GSHP) project is increasing, but the lack of summary analysis of different GSHP system to run the specific energy efficiency and other practical operation of the specific test and investigation, which will focus on this study the content and direction. Based on the actual test data and field investigation results of the GSHP system in the above projects, the key demonstration projects of GSHP in 30 countries are analyzed, including the basic conditions of the project, unit water temperature, unit performance, system performance and energy efficiency evaluation. On this basis, the advantages and disadvantages of each project and the energy efficiency situation are summarized and analyzed, and the adaptability of different types of technology in different regions are evaluated. Finally, the control strategies are proposed to enhance the energy efficiency of each project.
