Abstract
A case study of a ground source coupled heat pump and air conditioning system in China is introduced in the paper. Two types of U shaped Ground Coupled Heat Exchangers (GCHE) were adopted. One is the conventional closed loop borehole heat exchanger, and the other is the heat exchanger buried in the foundation pile. The floor area to be heated in winter or cooled in the summer is 3715 m2, with a heating load of 148kW and a cooling load of 320kW. The system has been operated since 2003 and data for one year are summarized and analyzed. These data include the inlet and outlet temperatures of the GCHE and the surrounding soil temperature. The heating and cooling performances of the system are also evaluated.
