Abstract: The low temperature of the geothermal water about 10℃ can be promoted to 45℃~60℃ by the heat pump technique. The application of geothermal heat pump technique is a new method of using the energy of low enthalpy. The technical economics of the geothermal heat pump system and the beneficial effects on energy saving and environmental protection are analy sed. It is found that the geothermal heat pump technique is an economical system engineering with low pollution and a good future.

Key words: technique and economic analysis, geothermal-source heat pump, energy saving
