PURPOSE: A hybrid cold/hot water supply system using the terrestrial heat is provided to improve energy efficiency by connecting a cold/hot water line to a hybrid cooling/heating device with a terrestrial heat exchanger. CONSTITUTION: A hybrid cold/hot water supply system using the terrestrial heat comprises a compressor(1), a first heat exchanger(2), an expansion valve(3), a second heat exchanger(4), a geothermal exchanger(5), and a cold/hot water line(6). The compressor compresses a refrigerant, which circulates in a refrigerant line(10), at high pressure and high temperature. The second heat exchanger exchanges cold air or hot air by condensation or evaporation. The expansion valve expands the refrigerant. The second heat exchanger exchanges the heat of the cold air or the hot air with the outside by evaporation and condensation. The geothermal exchanger exchanges geothermal heat. The cold/hot water line circulates liquid heat exchange fluid to a cooling/heating load(100).
