Geothermal pump pick currently in the development of China with the best historic opportunity, the State has a number of environmental and energy laws and regulations, adopted environmental benefits of energy saving heat pumps offer endless possibilities for Geo-business and ‘ manufacturing industry in China are currently in full swing, geothermal heat pump energy efficiency of buildings done particularly well in recent years the demand for its further growth and development of geothermal heat pump has not been easy, the following analysis of pumps geothermal heat that we face in the process of development of six major problem in this area began, how to solve the following problem, leave the science.

(1) Concept: source heat pump air and gas, coal technology is relatively mature, so that people choose mass of the pump system with heat resistance.

(2) HVAC technology with other technologies: geothermal heat pump air conditioning systems and technology is a combination of integrated technology of drilling, are necessary, such projects are necessary for the organization and coordination of engineering technical staff and reasonable to make many technical and economic analysis.

(3) the impact on the environment: the technical deficiencies of groundwater recharge in progress, influenced to some extent, the source of heat and low water as a new promotion of geothermal heat pump and geothermal heat pump air conditioning drilling on soil temperature, moisture and salt migration should further research be considered as negative factors.

(4) the initial investment problem: Not all geothermal heat pump systems are economical, because the costs of drilling can change the whole system more than 50% of the initial investment, some investors to return to the traditional form of air conditioning.

(5) Installation and maintenance: the current installation of geothermal heat pump system costs and electric cooling, gas heating, 500 ~ 800 yuan per ton, compared with geothermal heat pump 600-100 yuan / t (1t = 1.01605t) seems high, and ‘the depreciation period is 5 to 8 years and the geothermal system makes maintenance of the pump, that relate in any way for its use.

(6) Soil properties: soil properties vary with changes in different places, in an area of study rather inappropriate for another region, should be amended accordingly, or even think.
