[0028] Embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present disclosure, and are not to be construed as limitations of the present disclosure. On the contrary, the embodiments of the present disclosure include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0029] like Figure 1As shown, the embodiment of the present disclosure proposes a multi-energy complementary energy supply system, including a ground source heat pump device 1, an air source heat pump device 2, an energy storage device 3 and an energy supply device 4, wherein the liquid inlet end of the energy supply device 4 is respectively connected to the liquid outlet end of the ground source heat pump device 1, the liquid outlet end of the air source heat pump device 2 and the liquid outlet end of the energy storage device 3, the liquid outlet end of the energy supply device 4 is respectively connected to the liquid inlet end of the ground source heat pump device 1, the liquid inlet end of the air source heat pump device 2 and the liquid inlet end of the energy storage device 3, and the energy supply device 4 is respectively connected to at least one of the passages between the ground source heat pump device 1, the air source heat pump device 2 and the energy storage device 3.

[0030] It can be understood that, since the liquid outlet of the ground source heat pump device 1 is connected to the liquid inlet of the energy supply device 4, and the liquid inlet of the ground source heat pump device 1 is connected to the liquid outlet of the energy supply device 4, the ground source heat pump device 1 can use the heat energy or cold energy in the ground source to supply energy to the energy supply device 4, and then use the energy supply device 4 to realize the supply of heat energy or cold energy; since the liquid outlet of the air source heat pump device 2 is connected to the liquid inlet of the energy supply device 4, and the liquid inlet of the air source heat pump device 2 is connected to the liquid outlet of the energy supply device 4, The air source heat pump device 2 can utilize the heat energy or cold energy in the air source to supply energy to the energy supply device 4, and then utilize the energy supply device 4 to realize the supply of heat energy or cold energy; since the liquid outlet end of the energy storage device 3 is connected to the liquid inlet end of the energy supply device 4, and the liquid inlet end of the energy storage device 3 is connected to the liquid outlet end of the energy supply device 4, the energy storage device 3 can store the remaining heat energy or cold energy in the energy supply device 4, and utilize the stored heat energy or cold energy to supply energy to the energy supply device 4, and then utilize the energy supply device 4 to realize the supply of heat energy or cold energy.

[0031] Among them, the system can use the ground source heat pump device 1, the air source heat pump device 2 or the energy storage device 3 to realize the supply of heat or cold energy, so as to meet the demand for heat or cold. At the same time, the system can also realize the flexible coupling of the ground source heat pump device 1 and the air source heat pump device 2, so that the overall low-cost energy supply advantages of the ground source heat pump device 1 and the high efficiency and high-quality energy supply advantages of the air source heat pump device 2 can be maximized. Moreover, the system can also use the energy storage and energy supply of the energy storage device 3 to reduce the overall energy consumption, thereby reducing the load of the power grid. Therefore, the system uses the coupling and complementarity of the ground source heat pump device 1, the air source heat pump device 2 and the energy storage device 3 to achieve high-performance operation and meet the use requirements.

[0032] It should be noted that the ground source heat pump device 1 uses the heat or cold energy in the ground source to supply energy to the energy supply device 4. The specific type of the ground source heat pump device 1 can be set according to actual needs and is not limited to this. Among them, the ground source can be soil, groundwater, surface water, etc.

[0033] The air source heat pump device 2 uses the heat energy or cold energy in the air source to supply energy to the energy supply device 4. The specific type of the air source heat pump device 2 can be set according to actual needs, and there is no limitation on this. For example, the air source heat pump device 2 includes a third passage 201, the liquid outlet of the third passage 201 is connected to the liquid inlet of the energy supply device 4, and the liquid inlet of the third passage 201 is connected to the liquid outlet of the energy supply device 4, and the third passage 201 exchanges heat with the air source. The air source can be a gas such as carbon dioxide, so that the heat energy or cold energy in the air source is used to supply energy to the energy supply device 4, and environmental pollution can also be avoided.

[0034] Among them, the energy supply quality and energy supply efficiency of the ground source heat pump device 1 are lower than those of the air source heat pump device 2. For example, the heat energy temperature provided by the ground source heat pump device 1 is only about 40 degrees, while the heat energy temperature provided by the air source heat pump device 2 can reach about 70 degrees or even 90 degrees.

[0035] The energy storage device 3 stores the remaining heat energy or cold energy in the energy supply device 4, and uses the stored heat energy or cold energy to supply energy to the energy supply device 4. The specific type of the energy storage device 3 can be set according to actual needs and is not limited to this. For example, the energy storage device 3 can be an energy storage tank, an energy storage tower, etc. When the heat exchange fluid in the energy supply device 4 passes through the energy storage device 3, part of the heat exchange fluid is stored in the energy storage device 3, thereby realizing the storage of heat energy or cold energy.

[0036] The specific type of the heat exchange fluid can be set according to actual needs and is not limited thereto. For example, the heat exchange fluid can be pure water or the like.

[0037] The energy supply device 4 is used to provide heat energy or cold energy by heat exchange. The specific type of the energy supply device 4 can be set according to actual needs and is not limited to this. For example, the energy supply device 4 can be a fan coil unit.

[0038] The operation mode of the system can be set according to actual needs, and there is no restriction on this. For example, when the energy supply demand of the energy supply device 4 is small, the system can only use the ground source heat pump device 1 to supply energy to the energy supply device 4; when the energy supply demand of the energy supply device 4 is large, the system can only use the air source heat pump device 2 to supply energy to the energy supply device 4. At the same time, in order to achieve high-performance operation, the system can also use the ground source heat pump device 1 and the air source heat pump device 2 to supply energy to the energy supply device 4 at the same time; when the grid load is large and is at a peak period of electricity consumption, the system can only use the energy storage device 3 to supply energy to the energy supply device 4, and no matter whether the ground source heat pump device 1 supplies energy to the energy supply device 4 or the air source heat pump device 2 supplies energy to the energy supply device 4, the energy storage device 3 can be turned on and store the remaining heat energy or cold energy in the energy supply device 4.

[0039] like Figure 1As shown, in some embodiments, the ground source heat pump device 1 includes a first passage 101 and a second passage 102, the first passage 101 is used for heat exchange with the ground source, and the second passage 102 exchanges heat with the first passage 101, wherein the liquid inlet end of the energy supply device 4 is respectively connected to the liquid inlet end of the first passage 101 and the liquid outlet end of the second passage 102, the liquid outlet end of the energy supply device 4 is respectively connected to the liquid outlet end of the first passage 101 and the liquid inlet end of the second passage 102, and the energy supply device 4 is respectively connected to at least one of the passages between the first passage 101, the second passage 102, the air source heat pump device 2 and the energy storage device 3.

[0040] It can be understood that, since the first passage 101 exchanges heat with the ground source, and the second passage 102 exchanges heat with the first passage 101, the second passage 102 can utilize the first passage 101 to exchange heat with the ground source, and since the liquid outlet of the second passage 102 is connected to the liquid inlet of the energy supply device 4, and the liquid inlet of the second passage 102 is connected to the liquid outlet of the energy supply device 4, the second passage 102 can provide the heat or cold energy in the ground source to the energy supply device 4; since the liquid inlet of the first passage 101 is connected to the liquid inlet of the energy supply device 4, and the liquid outlet of the first passage 101 is connected to the liquid outlet of the energy supply device 4, the first passage 101 can provide the heat or cold energy in the ground source to the energy supply device 4. Therefore, by using the settings of the first passage 101 and the second passage 102, the system can use the ground source heat pump device 1 to supply energy to the energy supply device 4, and then use the energy supply device 4 to realize the supply of heat or cold energy.

[0041] It should be noted that, since the first passage 101 directly provides the heat or cold energy of the ground source to the energy supply device 4, the energy supply quality of the first passage 101 is lower than that of the second passage 102. For example, the heat temperature provided by the first passage 101 is lower than that of the second passage 102. When the energy supply demand of the energy supply device 4 is relatively small, the system can only use the first passage 101 to supply energy to the energy supply device 4; when the energy supply demand of the energy supply device 4 is slightly larger, the system can only use the second passage 102 to supply energy to the energy supply device 4; when the energy supply demand of the energy supply device 4 is relatively large, the system can also use the second passage 102 and the air source heat pump device 2 to supply energy to the energy supply device 4 at the same time.

[0042] like Figure 1As shown, in some embodiments, the ground source heat pump device 1 also includes a plurality of heat exchange tubes (not shown in the figure), a water collector 103 and a water distributor 104. The plurality of heat exchange tubes are respectively arranged in the ground source and exchange heat with the ground source. The plurality of liquid inlet ends of the water collector 103 are respectively connected to the liquid outlet ends of the plurality of heat exchange tubes, the liquid outlet end of the water collector 103 is respectively connected to the liquid inlet end of the first passage 101 and the liquid inlet end of the energy supply device 4, the liquid inlet end of the water distributor 104 is respectively connected to the liquid outlet end of the first passage 101 and the liquid outlet end of the energy supply device 4, and the plurality of liquid outlet ends of the water distributor 104 are respectively connected to the liquid inlet ends of the plurality of heat exchange tubes.

[0043] It can be understood that since the liquid inlet end of the water collector 103 is connected to the liquid outlet end of the heat exchange tube, and the liquid outlet end of the water collector 103 is connected to the liquid inlet end of the first passage 101, the liquid inlet end of the water distributor 104 is connected to the liquid outlet end of the first passage 101, and the liquid outlet end of the water distributor 104 is connected to the liquid inlet end of the heat exchange tube, a first heat exchange circuit including the first passage 101 is formed in the ground source heat pump device 1, thereby facilitating the use of the first heat exchange circuit to transfer heat energy or cold energy in the ground source to the second passage 102, and then provide it to the energy supply device 4 to meet the use requirements.

[0044] Since the liquid inlet end of the water collector 103 is connected to the liquid outlet end of the heat exchange tube, and the liquid outlet end of the water collector 103 is connected to the liquid inlet end of the energy supply device 4, the liquid inlet end of the water distributor 104 is connected to the liquid outlet end of the energy supply device 4, and the liquid outlet end of the water distributor 104 is connected to the liquid inlet end of the heat exchange tube, a second heat exchange circuit that does not include the first passage 101 is formed in the ground source heat pump device 1, thereby facilitating the use of the second heat exchange circuit to provide heat energy or cold energy in the ground source to the energy supply device 4 to meet the use requirements.

[0045] Among them, since multiple heat exchange tubes are provided, multiple heat exchange tubes can exchange heat with the ground source at the same time, thereby effectively improving the energy supply efficiency and energy supply quality of the ground source heat pump device 1.

[0046] It should be noted that the specific type and quantity of the heat exchange tubes can be set according to actual needs and are not limited to this. For example, the heat exchange tubes are buried underground, and the heat exchange fluid passing through the heat exchange tubes directly exchanges heat with underground soil, groundwater, etc.

[0047] The water collector 103 is used to collect the heat exchange fluid in a plurality of heat exchange tubes for centralized transportation and energy supply. The specific type of the water collector 103 can be set according to actual needs and is not limited thereto.

[0048] The water distributor 104 is used to distribute the energized heat exchange fluid into a plurality of heat exchange tubes. The specific type of the water distributor 104 can be set according to actual needs and is not limited thereto.

[0049] like Figure 1As shown, in some embodiments, the multi-energy complementary energy supply system also includes a first valve body 8, a second valve body 9 and a third valve body 10. The first valve body 8 is arranged between the liquid outlet end of the water collector 103 and the liquid inlet end of the energy supply device 4, and the liquid inlet end of the first valve body 8 is connected to the liquid outlet end of the water collector 103, and the liquid outlet end of the first valve body 8 is connected to the liquid inlet end of the energy supply device 4. The second valve body 9 is arranged between the liquid outlet end of the water collector 103 and the liquid inlet end of the first passage 101, and the liquid inlet end of the second valve body 9 is connected to the liquid outlet end of the water collector 103, and the liquid outlet end of the second valve body 9 is connected to the liquid inlet end of the first passage 101. The third valve body 10 is arranged between the liquid inlet end of the water distributor 104 and the liquid outlet end of the energy supply device 4, and the liquid inlet end of the third valve body 10 is connected to the liquid outlet end of the energy supply device 4, and the liquid outlet end of the third valve body 10 is connected to the liquid inlet end of the water distributor 104.

[0050] It can be understood that since the liquid inlet end of the first valve body 8 is connected to the liquid outlet end of the water collector 103, and the liquid outlet end of the first valve body 8 is connected to the liquid inlet end of the energy supply device 4, the first valve body 8 can control the on-off and opening between the liquid outlet end of the water collector 103 and the liquid inlet end of the energy supply device 4; since the liquid inlet end of the second valve body 9 is connected to the liquid outlet end of the water collector 103, and the liquid outlet end of the second valve body 9 is connected to the liquid inlet end of the first passage 101, the second valve body 9 can control the on-off and opening between the liquid outlet end of the water collector 103 and the liquid inlet end of the first passage 101; since the liquid inlet end of the third valve body 10 is connected to the liquid outlet end of the energy supply device 4, and the liquid outlet end of the third valve body 10 is connected to the liquid inlet end of the water distributor 104, the third valve body 10 can control the on-off and opening between the liquid inlet end of the water distributor 104 and the liquid outlet end of the energy supply device 4.

[0051] Therefore, by setting the first valve body 8, the second valve body 9 and the third valve body 10, it is convenient to control the on-off between the energy supply device 4 and the first passage 101 and between the energy supply device 4 and the second passage 102, so that the system can select a suitable energy supply passage according to different energy supply requirements, thereby effectively improving the operating flexibility of the system and ensuring the realization of high-performance operation of the system.

[0052] It should be noted that when the first valve body 8 and the third valve body 10 are opened and the second valve body 9 is closed, the heat exchange fluid in the heat exchange tube directly enters the energy supply device 4 to provide heat energy or cold energy; when the first valve body 8 and the third valve body 10 are closed and the second valve body 9 is opened, the heat exchange fluid in the heat exchange tube enters the first passage 101 to utilize the second passage 102 to provide heat energy or cold energy for the energy supply device 4.

[0053] Among them, by adjusting the opening of the first valve body 8 and the third valve body 10, the flow rate of the heat exchange fluid in the energy supply device 4 can be adjusted, and then the supply of heat energy or cold energy of the energy supply device 4 can be adjusted; by adjusting the opening of the second valve body 9, the flow rate of the heat exchange fluid in the first passage 101 can be adjusted, thereby adjusting the supply of heat energy or cold energy of the second passage 102, and then adjusting the supply of heat energy or cold energy of the energy supply device 4.

[0054] The specific types of the first valve body 8, the second valve body 9 and the third valve body 10 can be set according to actual needs, and there is no limitation to this. For example, the first valve body 8, the second valve body 9 and the third valve body 10 can all be solenoid valves.

[0055] like Figure 1 As shown, in some embodiments, the multi-energy complementary energy supply system also includes multiple first pump bodies 5, the liquid inlet end of the first pump body 5 is connected to the liquid outlet end of the water collector 103, and the liquid outlet end of the first pump body 5 is respectively connected to the liquid inlet end of the first passage 101 and the liquid inlet end of the energy supply device 4, wherein at least two of the multiple first pump bodies 5 are opened at the same time.

[0056] It can be understood that since the liquid inlet end of the first pump body 5 is connected to the liquid outlet end of the water collector 103, and the liquid outlet end of the first pump body 5 is connected to the liquid inlet end of the first passage 101, the first pump body 5 can pressurize the heat exchange fluid in the water collector 103 and transport it to the first passage 101, thereby ensuring stable heat exchange between the first passage 101 and the second passage 102; since the liquid inlet end of the first pump body 5 is connected to the liquid outlet end of the water collector 103, and the liquid outlet end of the first pump body 5 is connected to the liquid inlet end of the energy supply device 4, the first pump body 5 can pressurize the heat exchange fluid in the water collector 103 and transport it to the energy supply device 4, thereby ensuring that the heat exchange tube stably provides heat energy or cold energy to the energy supply device 4.

[0057] Among them, since at least two of the multiple first pump bodies 5 are opened at the same time, the liquid outlet end of the water collector 103 has a larger conveying force, thereby ensuring the stable conveyance of the heat exchange fluid to the first passage 101 or the energy supply device 4.

[0058] It should be noted that the specific type and quantity of the first pump body 5 can be set according to actual needs, and there is no limitation on this. For example, three first pump bodies 5 can be set, and the three first pump bodies 5 are connected in parallel.

[0059] When the first valve body 8 or the second valve body 9 is opened, the first pump body 5 is opened, and when the first valve body 8 and the second valve body 9 are both closed, the first pump body 5 is closed.

[0060] like Figure 1As shown, in some embodiments, the multi-energy complementary energy supply system also includes a fourth valve body 11 and a fifth valve body 12, the fourth valve body 11 is arranged between the liquid outlet end of the energy supply device 4 and the liquid inlet end of the ground source heat pump device 1, and the liquid inlet end of the fourth valve body 11 is connected to the liquid outlet end of the energy supply device 4, the liquid outlet end of the fourth valve body 11 is connected to the liquid inlet end of the ground source heat pump device 1, the fifth valve body 12 is arranged between the liquid outlet end of the energy supply device 4 and the liquid inlet end of the air source heat pump device 2, and the liquid inlet end of the fifth valve body 12 is connected to the liquid outlet end of the energy supply device 4, and the liquid outlet end of the fifth valve body 12 is connected to the liquid inlet end of the air source heat pump device 2.

[0061] It can be understood that since the liquid inlet end of the fourth valve body 11 is connected to the liquid outlet end of the energy supply device 4, and the liquid outlet end of the fourth valve body 11 is connected to the liquid inlet end of the ground source heat pump device 1, the fourth valve body 11 can control the on-off and opening between the liquid outlet end of the energy supply device 4 and the liquid inlet end of the ground source heat pump device 1; since the liquid inlet end of the fifth valve body 12 is connected to the liquid outlet end of the energy supply device 4, and the liquid outlet end of the fifth valve body 12 is connected to the liquid inlet end of the air source heat pump device 2, the fifth valve body 12 can control the on-off and opening between the liquid outlet end of the energy supply device 4 and the liquid inlet end of the air source heat pump device 2.

[0062] Therefore, through the setting of the fourth valve body 11 and the fifth valve body 12, it is convenient to control the on-off between the energy supply device 4 and the ground source heat pump device 1 and between the energy supply device 4 and the air source heat pump device 2, so that the system can select a suitable energy supply path according to different energy supply requirements, thereby effectively improving the operating flexibility of the system and ensuring the realization of high-performance operation of the system.

[0063] It should be noted that when the fourth valve body 11 is opened and the fifth valve body 12 is closed, the system only uses the ground source heat pump device 1 to supply energy to the energy supply device 4; when the fourth valve body 11 is closed and the fifth valve body 12 is opened, the system only uses the air source heat pump device 2 to supply energy to the energy supply device 4; when the fourth valve body 11 is opened and the fifth valve body 12 is opened, the system simultaneously uses the ground source heat pump device 1 and the air source heat pump device 2 to supply energy to the energy supply device 4, and by adjusting the opening of the fourth valve body 11 and the fifth valve body 12, the performance of the system is optimized.

[0064] The specific types of the fourth valve body 11 and the fifth valve body 12 can be set according to actual needs, and there is no limitation to this. For example, the fourth valve body 11 and the fifth valve body 12 can both be solenoid valves.

[0065] The fourth valve body 11 is arranged at the liquid inlet end of the second passage 102 , and the fourth valve body 11 and the second valve body 9 are switched synchronously.

[0066] like Figure 1As shown, in some embodiments, the multi-energy complementary energy supply system also includes a reversing valve 7, a first end of the reversing valve 7 is respectively connected to the liquid outlet end of the energy supply device 4 and the liquid outlet end of the energy storage device 3, a second end of the reversing valve 7 is connected to the liquid inlet end of the energy supply device 4, and a third end of the reversing valve 7 is respectively connected to the liquid inlet end of the fourth valve body 11 and the liquid inlet end of the fifth valve body 12.

[0067] It can be understood that since the first end of the reversing valve 7 is connected to the liquid outlet end of the energy storage device 3, and the second end of the reversing valve 7 is connected to the liquid inlet end of the energy supply device 4, the liquid outlet end of the energy storage device 3 and the liquid inlet end of the energy supply device 4 can be connected by the reversing valve 7, so that the energy storage device 3 can provide heat energy or cold energy to the energy supply device 4 by utilizing the setting of the reversing valve 7.

[0068] Since the first end of the reversing valve 7 is connected to the liquid outlet end of the energy supply device 4, and the third end of the reversing valve 7 is respectively connected to the liquid inlet end of the fourth valve body 11 and the liquid inlet end of the fifth valve body 12, the liquid outlet end of the energy supply device 4 and the liquid inlet end of the ground source heat pump device 1 can be connected by using the reversing valve 7 and the fourth valve body 11, and the liquid outlet end of the energy supply device 4 and the liquid inlet end of the air source heat pump device 2 can be connected by using the reversing valve 7 and the fifth valve body 12. Therefore, by utilizing the setting of the reversing valve 7, the ground source heat pump device 1 and / or the air source heat pump device 2 can provide heat energy or cold energy for the energy supply device 4.

[0069] Therefore, by setting the reversing valve 7, the switching of the passages between the energy supply device 4 and the energy storage device 3, the ground source heat pump device 1, and the air source heat pump device 2 can be achieved, thereby meeting the flexible operation of the system and further improving the performance of the system.

[0070] It should be noted that when the first end and the second end of the reversing valve 7 are connected and the fourth valve body 11 and the fifth valve body 12 are closed, the system uses the energy storage device 3 to provide heat energy or cold energy to the energy supply device 4; when the first end and the third end of the reversing valve 7 are connected and the fourth valve body 11 and / or the fifth valve body 12 are opened, the system uses the ground source heat pump device 1 and / or the air source heat pump device 2 to provide heat energy or cold energy to the energy supply device 4, and the energy storage device 3 is in an energy storage state.

[0071] The specific type of the reversing valve 7 can be set according to actual needs, and there is no limitation to this. For example, the reversing valve 7 can be a solenoid valve.

[0072] like Figure 1 As shown, in some embodiments, the multi-energy complementary energy supply system also includes multiple second pump bodies 6, the liquid inlet ends of the second pump bodies 6 are respectively connected to the liquid outlet ends of the energy supply device 4 and the liquid outlet ends of the energy storage device 3, and the liquid outlet end of the second pump body 6 is connected to the first end of the reversing valve 7, wherein at least two of the multiple second pump bodies 6 are opened at the same time.

[0073] It can be understood that, since the liquid inlet end of the second pump body 6 is connected to the liquid outlet end of the energy supply device 4, and the liquid outlet end of the second pump body 6 is connected to the first end of the reversing valve 7, the second pump body 6 can pressurize the heat exchange fluid in the energy supply device 4 and transport it to the ground source heat pump device 1 and / or the air source heat pump device 2, thereby ensuring that the ground source heat pump device 1 and / or the air source heat pump device 2 provides stable energy to the energy supply device 4; since the liquid inlet end of the second pump body 6 is connected to the liquid outlet end of the energy storage device 3, and the liquid outlet end of the second pump body 6 is connected to the first end of the reversing valve 7, the second pump body 6 can pressurize the heat exchange fluid in the energy storage device 3 and transport it to the energy supply device 4, thereby ensuring that the energy storage device 3 provides stable energy to the energy supply device 4.

[0074] Among them, since at least two of the multiple second pump bodies 6 are opened at the same time, the first end of the reversing valve 7 has a larger conveying force, thereby ensuring the stable delivery of the heat exchange fluid to the ground source heat pump device 1, the air source heat pump device 2 and the energy supply device 4.

[0075] It should be noted that the specific type and quantity of the second pump body 6 can be set according to actual needs, and there is no limitation on this. For example, the second pump body 6 can be set to three, and the three second pump bodies 6 are connected in parallel.

[0076] Among them, when the first end and the second end of the reversing valve 7 are connected, the second pump body 6 is opened; when the first end and the third end of the reversing valve 7 are connected, and the fourth valve body 11 and / or the fifth valve body 12 are opened, the second pump body 6 is opened; when the first end and the second end of the reversing valve 7 are disconnected, and the first end and the third end of the reversing valve 7 are disconnected, the second pump body 6 is closed; when the first end and the third end of the reversing valve 7 are connected, and the fourth valve body 11 and the fifth valve body 12 are both opened, the second pump body 6 is closed.

[0077] like Figure 1 As shown, in some embodiments, the multi-energy complementary energy supply system also includes a sixth valve body 13, the sixth valve body 13 and the energy supply device 4 are connected in parallel, and the liquid inlet end of the sixth valve body 13 is connected to the liquid inlet end of the energy supply device 4, and the liquid outlet end of the sixth valve body 13 is connected to the liquid outlet end of the energy supply device 4.

[0078] It can be understood that since the liquid inlet end of the sixth valve body 13 is connected to the liquid inlet end of the energy supply device 4, and the liquid outlet end of the sixth valve body 13 is connected to the liquid outlet end of the energy supply device 4, the sixth valve body 13 can control the flow of the energy supply device 4, so that the system can select appropriate energy supply flow and energy storage flow according to different energy supply requirements, thereby effectively improving the operating flexibility of the system and ensuring the realization of high-performance operation of the system.

[0079] It should be noted that when the sixth valve body 13 is opened, part of the heat exchange fluid passes through the energy supply device 4 and participates in the energy supply, and the remaining heat exchange fluid passes through the sixth valve body 13 and does not participate in the energy supply; when the sixth valve body 13 is closed, all the heat exchange fluid passes through the energy supply device 4 and participates in the energy supply.

[0080] The specific type of the sixth valve body 13 can be set according to actual needs, and there is no limitation on this. For example, the sixth valve body 13 can be a solenoid valve.

[0081] like Figure 1 As shown, in some embodiments, the multi-energy complementary energy supply system further includes a seventh valve body 14, an eighth valve body 15 and a ninth valve body 16, the seventh valve body 14 is arranged between the liquid outlet end of the energy supply device 4 and the liquid inlet end of the energy storage device 3, and the liquid inlet end of the seventh valve body 14 is connected to the liquid outlet end of the energy supply device 4, the liquid outlet end of the seventh valve body 14 is connected to the liquid inlet end of the energy storage device 3, and the eighth valve body 15 is arranged at the liquid outlet end of the energy supply device 4, which is respectively connected to the liquid inlet end and the air inlet end of the ground source heat pump device 1. The eighth valve body 15 is connected to the liquid inlet end of the ground source heat pump device 1 and the liquid inlet end of the air source heat pump device 2, and the liquid inlet end of the eighth valve body 15 is connected to the liquid outlet end of the energy supply device 4, the liquid outlet end of the eighth valve body 15 is respectively connected to the liquid inlet end of the ground source heat pump device 1 and the liquid inlet end of the air source heat pump device 2, the ninth valve body 16 is arranged between the liquid outlet end of the energy storage device 3 and the liquid inlet end of the energy supply device 4, the liquid inlet end of the ninth valve body 16 is connected to the liquid outlet end of the energy storage device 3, and the liquid outlet end of the ninth valve body 16 is connected to the liquid inlet end of the energy supply device 4.

[0082] It can be understood that, since the liquid inlet end of the seventh valve body 14 is connected to the liquid outlet end of the energy supply device 4, and the liquid outlet end of the seventh valve body 14 is connected to the liquid inlet end of the energy storage device 3, the seventh valve body 14 can control the on-off and opening between the liquid outlet end of the energy supply device 4 and the liquid inlet end of the energy storage device 3; since the liquid inlet end of the eighth valve body 15 is connected to the liquid outlet end of the energy supply device 4, and the liquid outlet end of the eighth valve body 15 is respectively connected to the liquid inlet end of the ground source heat pump device 1 and the liquid inlet end of the air source heat pump device 2 , so that the eighth valve body 15 can control the on-off and opening between the liquid outlet end of the energy supply device 4 and the liquid inlet end of the ground source heat pump device 1, as well as the on-off and opening between the liquid outlet end of the energy supply device 4 and the liquid inlet end of the air source heat pump device 2; because the liquid inlet end of the ninth valve body 16 is connected to the liquid outlet end of the energy storage device 3, and the liquid outlet end of the ninth valve body 16 is connected to the liquid inlet end of the energy supply device 4, the ninth valve body 16 can control the on-off and opening between the liquid outlet end of the energy storage device 3 and the liquid inlet end of the energy supply device 4.

[0083] Therefore, through the setting of the seventh valve body 14, the eighth valve body 15 and the ninth valve body 16, it is convenient to control the switching of the energy storage device 3 between the energy storage state and the energy supply state, so that the system can select a suitable energy supply path according to different energy supply requirements, thereby effectively improving the operating flexibility of the system and ensuring the realization of high-performance operation of the system.

[0084] It should be noted that when the seventh valve body 14 and the ninth valve body 16 are opened and the eighth valve body 15 is closed, the energy storage device 3 is in an energy storage state; when the seventh valve body 14 and the ninth valve body 16 are opened and the eighth valve body 15 is opened, the energy storage device 3 is in an energy storage state, and the storage amount of the energy storage device 3 can be adjusted by adjusting the opening of the seventh valve body 14, the eighth valve body 15 and the ninth valve body 16; when the seventh valve body 14 and the ninth valve body 16 are closed and the eighth valve body 15 is opened, the energy storage device 3 is in an energy supply state.

[0085] When the seventh valve body 14 and the ninth valve body 16 are opened, the first end and the second end of the reversing valve 7 are connected, and when the seventh valve body 14 and the ninth valve body 16 are closed, the first end and the third end of the reversing valve 7 are connected.

[0086] Taking the system heating energy as an example, when the actual temperature is much higher than the temperature required for heating, the energy supply device 4 and the eighth valve body 15 are closed, and the sixth valve body 13, the seventh valve body 14, the ninth valve body 16 and the second pump body 6 are opened, so that the energy storage device 3 is in the energy storage state;

[0087] When the actual temperature is greater than the temperature required for heating, the energy supply device 4 is opened, the sixth valve body 13 is closed, and the seventh valve body 14, the ninth valve body 16 and the second pump body 6 are kept open, and the eighth valve body 15 is kept closed, so that the energy storage device 3 is in an energy storage state, and the energy supply device 4 is in a heating state;

[0088] When the actual temperature is lower than the temperature required for heating, the energy supply device 4 and the second pump body 6 are kept open, the seventh valve body 14 and the ninth valve body 16 are closed, and the eighth valve body 15 is opened at the same time, so that the energy supply device 4 is in a heating state.
