| Geothermal-source heat pump is one of the main ways human being used renewable energy. Using geothermal-source heat pump heating technology can save energy and protect environment. The underground soil thermal conductivity of Xinjiang area is low. If adopt geothermal-source heat pump for a long time, the efficiency of heat pump is very low. Meanwhile Solar energy of Xinjiang area is abundant. Solar assisted geothermal-source heat pump system is adopted for the purpose of fully utilizing the abundant solar and geothermal-source in Xinjiang. The combing solar collector and geothermal-source heat pump heating system is more effective and economic.In this paper, through analysis of solar assisted geothermal-source heat pump system development situation and research trends of combing heating technology, based on solar assisted geothermal-source heat pump system experimental table which was built by xinjiang new energy research institute, it researched on technical and economic of the combing heating system, it studied for the result and the shortcoming of the combing heating system. The result showed that solar energy assisted geothermal-source heat pump system is technical and economic in xinjiang area. Solar assisted geothermal-source heat pump system is completely feasible in xinjiang area.This paper supply base of solar energy assisted geothermal-source heat pump system in xinjiang area. It has very important reference and practical values for the purpose of the combing application of solar assisted geothermal-source heat pump system in xinjiang area.
