The present invention provides a water source heat pump air-conditioning equipment whose heat-exchanger is embedded in the underground water-course. It includes water source heat pump and user end air-conditioning equipment connected with output end of water source heat pump, in the water source input end of said water source heat pump is connected a heat-exchanger which is embedded in underground water-course and is formed into a closed water circulation loop together with water source side of said water source heat pump by means of pipeline with circulation water pump. Said invention adopts the heat-exchanger embedded in underground water-course to obtain underground cold quantity and heat quantity and provide cold and heat sources for high-effective operation of water source heat pump, so that it can greatly raise the refrigerating and heat-producing efficiency of said water source heat pump. |
