Study on Performance of Ground Source Heat Pump Systems Based on Site Tests

Abstract:

This study analyze the actual operation performance and energy efficiency of thirty-nine ground source heat pump (GSHP) systems based on site tests in Wuhan, China. These systems include ground couple heat pump (GCHP) systems, ground water heat pump (GWHP) systems and hybrid ground source heat pump (HGSHP) systems. The results show that energy-saving rates reach 30% for most of the systems using method recommended by Assessment Guideline. The coefficient of performance (COP) of the systems varies as follow: 2.6-4.85 for GCHP systems; 2.58-3.74 for GWHP systems; 2.66-5.67 for combined heat pump systems. According to the test results and system design data, analyses the factors affecting the system performance of three types of ground source heat pump systems.
