[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] This high-temperature water source heat pump air conditioning unit, such as Figures 1-3 As shown, the system includes an air conditioner body 1. An outlet and an inlet are located on one side of the air conditioner body 1. An outlet pipe 2 is fixedly connected to the outlet, and an inlet pipe 3 is fixedly connected to the inlet. Two fixing plates 4 are bolted to one side of the air conditioner body 1. A filter box 5 is fixedly connected to the side of the fixing plate 4 away from the air conditioner body 1. Both the outlet pipe 2 and the inlet pipe 3 pass through the filter box 5 and lead to a water intake point. A water pump box 6 is fixedly connected to the top of the filter box 5. Two water pumps are fixedly connected inside the water pump box 6. The two water pumps are used for water intake through the inlet pipe 3 and water output through the outlet pipe 2, respectively. The main function of the inlet pipe 3 is to introduce external water into the water source heat pump system. For situations requiring heating, groundwater, surface water (such as river water, lake water), or other suitable water sources can be used. When used as a heat source, the inlet pipe 3 delivers relatively high-temperature water to the interior of the air conditioner body 1. Similarly, in cooling mode, the inlet pipe 3 introduces relatively low-temperature water as a cold source. After completing the heat or cold exchange, the outlet pipe 2 discharges the water from the water source heat pump system. However, the water source from the outside contains a lot of impurities. To prevent impurities from entering the air conditioner body 1, a filter device 8 is fixedly connected inside the filter box 5, and the bottom and top of the filter device 8 are connected to the inlet pipe 3. A water pressure gauge 9 is fixedly connected to the upper side of the outlet pipe 2. The water pressure gauge 9 is used to detect the pressure of the recharge and ensure the stability of the recharge process. A switch door 7 is rotatably connected to the side of the filter box 5 away from the air conditioner body 1 for the convenience of operators to check the equipment.

[0018] like Figures 1-3As shown, the filter device 8 comprises a filter barrel 81, a motor 82, a plurality of filter plates 83, and an impeller 84. The filter plates 83 are fixedly connected to the inner wall of the filter barrel 81. A sealing layer 10 is filled in the gap between each filter plate 83 and the filter barrel 81. The sealing layer 10 has waterproof performance and can improve the connectivity between the filter plate 83 and the filter barrel 81. The filter plate 83 comprises a first filter plate 831, a second filter plate 832, and a third filter plate 833 from top to bottom. The filtering efficiency of the first filter plate 831 is greater than that of the second filter plate 832, and the filtering efficiency of the second filter plate 832 is greater than that of the third filter plate 833. The third filter plate 833 is filled with activated carbon. The activated carbon has strong adsorption capacity and can remove impurities such as odor, color, and organic matter in water. The third filter plate 833 is mainly used for the first layer of protection in the filter device 8 and is mainly aimed at larger impurities such as leaves, branches, and even plastic bags. The second filter plate 832 is filled with quartz sand. The quartz sand can effectively remove suspended solids in water and has a significant effect on colloids, iron, organic matter, pesticides, manganese, bacteria, viruses, and other pollutants in water. The inner side of the first filter plate 831 is filled with metal fiber sintered felt. The metal fiber sintered felt has the advantages of high filtering precision, high temperature resistance, and corrosion resistance. The first filter plate 831 and the second filter plate 832 are mainly aimed at impurities that cannot be adsorbed by the third filter plate 833. This can make the water entering the air conditioner body 1 free of impurities and make the water after backfilling more clean, protect the environment, and be beneficial to resource recycling.

[0019] As shown, Figures 1-3 The motor 82 is fixedly connected to the first filter plate 831. The motor 82 is a waterproof motor 82. The driving end of the motor 82 is fixedly connected with a rotating roller 85. The rotating roller 85 penetrates through the plurality of filter plates 83. The impeller 84 is fixedly connected to the rotating roller 85. The impeller 84 comprises a first impeller 841, a second impeller 842, and a third impeller 843 from top to bottom. The size of the first impeller 841 is smaller than that of the second impeller 842, and the size of the second impeller 842 is smaller than that of the third impeller 843. The impeller 84 is mainly used to prevent impurities adsorbed on the surface of the filter plate 83 from always blocking the original position, thereby avoiding affecting the filtering effect. The third impeller 843 needs to stir a large amount of impurities, so a larger specification is required. In contrast, the first impeller 841 and the second impeller 842 need to stir relatively smaller impurities. In order to save resources, smaller impellers 84 are used. The bottom end of the rotating roller 85 is rotatably connected with a rotating shaft 86. The outer wall of the rotating shaft 86 is fixedly connected with a plurality of fixed rods 87. The other end of each fixed rod 87 is fixedly connected with the inner wall of the filter barrel 81. The fixed rods 87 limit the bottom end of the rotating roller 85 together with the rotating shaft 86, thereby improving the stability of the whole and making the whole more secure and durable.

[0020] The above merely is preferred implementation manner of the present application, the protection scope of the present application is not only limited to the above examples, and belongs to the technical scheme under the idea of the present application all belongs to the protection scope of the present application. It should be pointed out that, for ordinary skilled person in the art, under the premise of not departing from the principle of the present application, some improvements and decorations, these improvements and decorations should also be considered as the protection scope of the present application.
