Discussion the Shallow Ground Low Temperature Geothermal Energy and the Method of Application

The shallow ground low temperature geothermal en ergy as a kind of new energy, match with mature heat pump technique ,coming into ground source heat pump system and ground water source heat pump system,those t wo system ,develop the viigin soil in refrigeration and heating area ,have low i nvestment and low running expending compare with tradictional system, at the sam e time, It is difficult to apply to more district for technical problems and the restrict in the applied district This passage discusses the applied principle , applied meth od, investment,running expending in appling the shallow ground low temperature geothermal energy.
