Abstract

A ground source heat pump (GSHP) is paying attention as one of the energy saving technologies. The purpose of this study is to investigate the heat exchanging performance of the ground source heat pump system using direct expansion method. The direct expansion method is efficient compared to the indirect heat exchange method which is known as conventional technique. The GSHP system using direct expansion method circulates the refrigerant to underground directly. The calorimetric measurement in primary side of GSHP system using direct expansion method is difficult because the refrigerant which circulates to underground is two phase flow. Therefore, the performance of GSHP system is evaluated in secondary side by measuring the enthalpy difference. The accuracy of measurement is also evaluated in this study.
