the specific embodiment 1
As shown in Figure 1,
Technical scheme of the present invention is: a kind of underground water type ground source heat pump water heater, comprise geothermal energy exchange system, water-loop heat pump Hot water units 7, heat exchanger 13, water storage tank 15, hot water supply-water pump 12, wherein:
Described geothermal energy exchange system comprises underground water type underground pipe 1, source water water collector 2, source water separator 3, desander 4, electric water treatment device 5, underground heat water circulating pump 6, the underground pipe that described underground water type underground pipe 1 has discharge orifice by a plurality of lower ends composes in parallel, all underground pipes adopt reversed return type to connect, finally by pipeline, be connected with one end of source water separator 3 with one end of source water water collector 2 respectively, the other end of source water water collector 2 is connected with desander 4, desander 4 is connected with electric water treatment device 5, electric water treatment device 5 is connected with underground heat water circulating pump 6, underground heat water circulating pump 6 is connected with water-loop heat pump Hot water units 7, the other end of source water separator 3 is directly connected with water-loop heat pump Hot water units 7,
