The data for this study were collected within a six-month period, from October 2011 to March 2012. This study first analyzed the energy consumption from the device combining geothermal energy and the plate heat exchanger, as shown in Fig. 3, and then recorded the annual electricity and water consumption expenses. The data were compared to the expenses of energy consumption based on the early boiler heating system to evaluate quantitatively the per- formance of the geothermally assisted air-conditioning system.
