将下列段落翻译 Geothermal heat pumps, which use the earth as a heat sink in the summer and a heat source in the winter are viable nationwide.Therefore,they rely on the relative warmth of the earth for their heating and cooling production .Through a system of underground ( or underwater ) pipes, they transfer heat from the warmer earth or water source to the building in the winter, and take the heat from the building in the summer and discharge it into the cooler ground. Therefore, geothermal heat pumps don’t create heat. And they merely move it from one area to another.
