[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0033] Reference Figures 1-6 As shown, the utility model discloses a heat pump energy supply system, comprising: a heat pump 1, a first heat exchanger 2, a second heat exchanger 3, a groundwater source 4, an energy supply terminal 5 and a domestic water terminal 6;

[0034] Reference Figure 2 As shown, the groundwater source 4, the first heat exchanger 2, the heat pump 1 and the energy supply terminal 5 constitute a heating circuit, the first heat exchanger 2 is connected to the groundwater source 4 and the heat pump 1 respectively, and the heat pump 1 is connected to the energy supply terminal 5;

[0035] Reference Figure 3 As shown, the groundwater source 4, the first heat exchanger 2, the heat pump 1, the energy supply terminal 5, the second heat exchanger 3, the heat pump 1 and the domestic water terminal 6 constitute a first hot water loop, the first heat exchanger 2 is connected to the groundwater source 4 and the heat pump 1 respectively, the heat pump 1 is connected to the second heat exchanger 3 and the energy supply terminal 5, and the domestic water terminal 6 is connected to the second heat exchanger 3;

[0036] Reference Figure 4 As shown, the underground water source 4, the first heat exchanger 2 and the energy supply terminal 5 constitute a cooling circuit, and the first heat exchanger 2 is connected to the underground water source 4 and the energy supply terminal 5 respectively;

[0037] Reference Figure 5 As shown, the groundwater source 4, the first heat exchanger 2, the heat pump 1, the energy supply terminal 5, the second heat exchanger 3 and the domestic water terminal 6 constitute a second hot water circuit, the first heat exchanger 2 is respectively connected to the groundwater source 4 and the heat pump 1, the second heat exchanger 3 is respectively connected to the heat pump 1 and the domestic water terminal 6; the heat pump 1 is connected to the energy supply terminal 5;

[0038] Reference Figure 6 As shown, the groundwater source 4, the first heat exchanger 2, the heat pump 1, the second heat exchanger 3 and the domestic water end 6 constitute a third hot water loop, the heat pump 1 is connected to the first heat exchanger 2 and the second heat exchanger 3 respectively, the first heat exchanger 2 is connected to the groundwater source 4, and the second heat exchanger 3 is connected to the domestic water end 6.

[0039] The energy source of the heat pump energy supply system in this utility model is the groundwater source 4, the main source of which is the underground drainage water source of the project. Figure 2 As shown, the above-mentioned heating circuit is a single heating circuit, which is mainly used for heating the energy supply terminal 5 in winter. The specific energy supply is as follows: the groundwater source 4 enters the first heat exchanger 2 for heat exchange and is then discharged from the drain outlet 23. The heat pump 1 heats the low-temperature heat energy absorbed by the first heat exchanger 2 into high-temperature heat energy, and then transports the high-temperature heat energy to the energy supply terminal 5 for heating at the energy supply terminal 5.

[0040] Reference Figure 3 As shown, the first hot water circuit adds hot water output on the basis of single heating, which is used to realize winter heating and hot water output at the same time. The specific energy supply is as follows: the second heat exchanger 3 absorbs the high-temperature heat energy of the heat pump 1, and the domestic water end 6 inputs cold water into the second heat exchanger 3. After energy exchange in the second heat exchanger 3, hot water is output to the domestic water end 6.

[0041] Reference Figure 4 As shown, the cooling circuit is only a single cooling circuit, which is used for cooling the energy supply terminal 5 in summer. The specific energy supply is as follows: the groundwater source 4 enters the first heat exchanger 2, and after temperature exchange, the low-temperature energy is transmitted to the energy supply terminal 5 for continuous cooling of the energy supply terminal 5.

[0042] Reference Figure 5 As shown, the second hot water circuit is based on the cooling system, which is used to output hot water while providing cooling in summer. The specific energy supply is as follows: the first heat exchanger 2 exchanges energy in the groundwater, and then enters the heat pump 1 for conversion. The heat pump 1 transmits the low-temperature energy to the energy supply terminal 5 for cooling; the heat pump 1 transmits the high-temperature heat energy to the second heat exchanger 3. After energy exchange in the second heat exchanger 3, hot water is output to the domestic water end 6.

[0043] Reference Figure 6 As shown, the third hot water circuit is a single heating domestic water mode, which only provides domestic hot water. The energy supply terminal 5 does not need energy supply. The specific energy supply is as follows: the first heat exchanger 2 exchanges the energy in the groundwater source 4 and inputs it into the heat pump 1. The heat pump 1 heats the low-temperature energy into high-temperature thermal energy and transmits the high-temperature thermal energy to the second heat exchanger 3. After heat exchange in the second heat exchanger 3, hot water is output to the domestic water terminal 6.

[0044] The heat pump system 1 of the present invention achieves cooling, heating, and hot water output to the energy supply terminal 5 by exchanging energy from the groundwater source 4. During the energy exchange process, the first heat exchanger 2 achieves temperature exchange between the groundwater source 4 and the heat pump 1, and the second heat exchanger 3 achieves temperature exchange between the domestic water and the heat pump 1. The heat pump 1 does not directly contact the groundwater source 4 or the water at the domestic water terminal 6, thus preventing internal scaling and corrosion of the heat pump 1 and extending its service life.

[0045] Furthermore, a first circulation loop is provided between the first heat exchanger 2 and the heat pump 1, and the first circulation loop includes a first water pump 8 and a first insulated water tank 7. The first water pump 8 is connected to the first insulated water tank 7 and the first heat exchanger 2 at both ends, and the heat pump 1 is connected to the first insulated water tank 7.

[0046] Specifically, a special circulating medium is stored inside the first insulated water tank 7. The first water pump 8 pumps the special circulating medium into the first heat exchanger 2 for energy exchange, and then enters the heat pump 1. The heat pump 1 then exchanges the energy in the medium and finally returns to the first insulated water tank 7.

[0047] Furthermore, in the cooling circuit and the second hot water circuit, the energy supply terminal 5 is connected to an end of the first water pump 8 away from the first heat exchanger 2 .

[0048] Specifically, in the heating circuit, the first hot water circuit and the third hot water circuit, the first circulation circuit participates in the work, while in the cooling circuit and the second hot water circuit, the first insulated water tank 7 does not participate in the circulation of the first water pump 8. The first water pump 8 pumps the medium with increased temperature directly into the first heat exchanger 2, and performs energy exchange again to complete the circulation of the medium in the energy supply terminal 5.

[0049] Furthermore, a first standby water inlet 11 is provided between the first water pump 8 and the first thermal insulation water tank 7 , and a first standby water outlet 12 is provided between the heat pump 1 and the first thermal insulation water tank 7 .

[0050] Specifically, the first backup water inlet 11 and the first backup water outlet 12 are arranged in the first circulation loop. According to different usage scenarios, when cold water is needed, cold water can be output through the first backup water outlet 12 and cold water can be replenished from the first backup water inlet 11.

[0051] Furthermore, a second circulation loop is provided between the second heat exchanger 3 and the heat pump 1, and the second circulation loop includes a second insulated water tank 9 and a second water pump 10, and the two ends of the second water pump 10 are respectively connected to the second insulated water tank 9 and the heat pump 1, and the heat pump 1 is connected to the second insulated water tank 9.

[0052] Specifically, the medium inside the second insulated water tank 9 is also a dedicated circulating medium, which is pumped into the heat pump 1 by the second water pump 10. After the medium undergoes energy exchange, it enters the second heat exchanger 3 and undergoes further energy exchange. Secondly, in the second and third hot water circuits, since the heat pump 1 simultaneously exchanges energy with the second insulated water tank 9 and the second heat exchanger 3, in order to ensure that the set temperature is reached, it is first circulated through the second insulated water tank 9. The second insulated water tank 9 can maintain a certain temperature for the medium. After multiple cycles, the temperature of the medium will continue to rise. After the temperature reaches the set value, the circulation of the second heat exchanger 3 is restarted to ensure the output water temperature of the domestic water end 6.

[0053] In actual use, a thermometer 17 is provided between the second water pump 10 and the heat pump 1. The thermometer 17 can detect the temperature of the water entering the heat pump 1. When the temperature reaches the set value, the throttle valve 16 between the heat pump 1 and the second heat exchanger 3 is opened to allow the medium to enter the second heat exchanger 3. A flowmeter 15 is provided between the throttle valve 16 and the second heat exchanger 3. The throttle valve 16 can be used to control the flow rate entering the second heat exchanger 3, thereby controlling the output temperature of the hot water.

[0054] Furthermore, in the heating circuit and the first hot water circuit, the energy supply terminal 5 is connected to an end of the second water pump 10 away from the heat pump 1 .

[0055] In the third hot water circuit, the first circulation circuit and the second circulation circuit are both merged into the third hot water circuit, and the energy supply terminal 5 does not participate in the circulation of the third hot water circuit.

[0056] Specifically, in both the second and third hot water loops, the second circulation loop participates in operation, while in the heating loop and the first hot water loop, the second insulated water tank 9 does not participate in the circulation of the second water pump 10. This allows the medium at the energy supply terminal 5 to be directly returned to the heat pump 1 through the second water pump 10, thereby ensuring the stability of the medium circulation volume within the energy supply terminal 5. Depending on the demand for domestic hot water, when the amount of domestic hot water required is large, the second insulated water tank 9 can be optionally incorporated into the loop to ensure the average temperature of the circulating medium within the energy supply system.

[0057] Furthermore, a second backup water inlet 13 is provided between the second insulated water tank 9 and the second water pump 10, and a second backup water outlet 14 is provided between the heat pump 1 and the second insulated water tank 9. Similarly, depending on different usage scenarios, the second backup water outlet 14 can be used to output backup heat, and the second backup water inlet 13 can be used to input backup heat, thereby ensuring the balance of the medium in the entire circulation loop.

[0058] As a preferred solution of the present invention, in the cooling circuit, heating can also be achieved by turning on the heat pump, which can be used to cool the above-ground working surface buildings in summer while heating the cold and damp underground working surface buildings.

[0059] Specifically, refer to Figure 7 As shown, it also includes an underground heating end 24. The underground water source 4, the first heat exchanger 2, the heat pump 1, the energy supply terminal 5, the underground heating end 24, the second backup water inlet 13, and the second backup water outlet 14 constitute a dual energy supply circuit (cooling and heating mode). The first heat exchanger 2 is connected to the underground water source 4 and the heat pump 1 respectively, and the heat pump 1 is connected to the energy supply terminal 5; the first water pump 8 is connected to the energy supply terminal 5 and the first heat exchanger 2 at both ends; the underground heating end 24 is connected to the second backup water inlet 13 and the second backup water outlet 14 at both ends. The specific energy supply is as follows: the first heat exchanger 2 exchanges energy in the underground water source 4 and then enters the heat pump 1. The heat pump 1 transmits low-temperature energy to the energy supply terminal 5 for cooling; the heat pump 1 transmits high-temperature heat energy to the underground heating end 24 through the second backup water outlet 14 to provide heating for the cold and damp buildings on the underground working surface. Similarly, the first water pump 8 is used to circulate the medium in the energy supply terminal 5 , and the second water pump 10 is used to circulate the medium in the underground heating terminal 24 .

[0060] In addition, in the second hot water circuit, the second standby water inlet 13 and the second standby water outlet 14 are connected to the underground heating end 24, which can realize cooling, heating and heating domestic water at the same time. Figure 8 As shown, the underground water source 4, the first heat exchanger 2, the heat pump 1, the energy supply terminal 5, the second heat exchanger 3, the domestic water terminal 6, the underground heating terminal 24, the second backup water inlet 13, and the second backup water outlet 14 constitute the fourth hot water circuit. Specifically, the energy supply is as follows: the first heat exchanger 2 exchanges energy from the underground water source 4 and then enters the heat pump 1. The heat pump 1 transmits the low-temperature energy to the energy supply terminal 5 for cooling. The second heat exchanger 3 absorbs the high-temperature heat energy from the heat pump 1. The domestic water terminal 6 inputs cold water into the second heat exchanger 3. After energy exchange within the second heat exchanger 3, hot water is output to the domestic hot water terminal 6. At the same time, the heat pump 1 can also transmit high-temperature heat energy through the second backup water outlet 14 to the underground heating terminal 24 to provide heat to the cold and damp buildings on the underground working surface. Similarly, the first water pump 8 circulates the medium in the energy supply terminal 5, and the second water pump 10 circulates the medium in the underground heating terminal 24.

[0061] Furthermore, a cyclone desander 18 and a bag filter 19 are provided between the groundwater source 4 and the heat exchanger.

[0062] Specifically, in actual use, the groundwater source 4 contains a large amount of particulate matter such as silt. Before entering the first heat exchanger 2, the groundwater source 4 is first coarsely filtered through the cyclone desander 18 and then finely filtered through the bag filter 19 to prevent silt from entering the first heat exchanger 2. As a preferred embodiment of the present invention, filters 20 are installed at the water inlets of the first water pump 8 and the second water pump 10 to prevent raw tape debris from entering the heat exchanger at the connection point of the pipeline during installation.

[0063] In addition, a liquid replenishment and discharge port 21 is provided on the pipeline between the energy supply terminal 5 and the heat pump 1, and the liquid replenishment and discharge port 21 is provided near the side of the energy supply terminal 5 for replenishing and replacing the medium inside the energy supply terminal 5. Preferably, a one-way valve 22 is provided on the pipeline near the side of the liquid replenishment and discharge port 21 near the heat pump 1 to prevent the medium from flowing back during shutdown and causing damage to the equipment.

[0064] In another embodiment of the present invention, the pipeline converging and diverting points in the above-mentioned system are connected by tees, and a throttle valve (not marked in the drawings) is provided at the pipeline switching position for switching the pipelines and coordinating the operation of the system in different modes.

[0065] A skid-mounted heat pump energy supply integrated cabin includes the heat pump energy supply system of the above-described embodiment and an external packaging box (labeled in the accompanying drawings). The heat pump 1, first heat exchanger 3, second heat exchanger 3, first insulated water tank 7, second insulated water tank 9, first water pump 8, second water pump 10, cyclone desander 18, and bag filter 19 are all bolted to the equipment base. The entire equipment is placed in the external packaging box (a 20-foot standard container), making it easy to move. Threaded or flanged quick-connect connectors are provided at the cyclone desander 18, energy supply terminal 5, first backup water inlet 11, first backup water outlet 12, second backup water inlet 13, second backup water outlet 14, and domestic water terminal 6, allowing for easy installation and removal of piping.

[0066] In summary, the present invention introduces a heat pump energy supply system and a skid-mounted heat pump energy supply integrated cabin. The present invention realizes multiple uses of one machine by exchanging energy in the underground water source discharged from the project. A single energy supply mode or a simultaneous energy supply mode of cold + warm + domestic hot water can be selected. During the energy exchange process of the heat pump 1, the first heat exchanger 2 realizes the energy exchange between the underground water source 4 of the project and the heat pump 1, and the second heat exchanger 3 realizes the energy exchange between the domestic water end 6 and the heat pump 1. The first heat exchanger 2, the second heat exchanger 3, the heat pump 1, the first insulated water tank 7, the second insulated water tank 9, and the energy supply end 5 circulate using a dedicated circulating medium, which does not directly contact the water from the underground water source 4 and the domestic water end 6, thereby avoiding the formation of scale and corrosion inside the heat pump 1, ensuring the operating efficiency of the heat pump 1, and extending the service life of the entire equipment.

[0067] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
