[0002] In the current context of tightening energy supply and increasing environmental protection requirements, there is a continuous pursuit of new energy sources that are both energy-saving and environmentally friendly, one of which is a heat pump. Since the heat pump can transfer low-temperature heat energy to high-temperature heat energy, natural and residual heat resources can be effectively utilized, thereby conserving primary energy resources for both residential and industrial use.

[0003] A existing patent with publication number CN103307800B discloses a heat pump system that includes a compressor, a four-way valve, a gas-liquid separator, an indoor heat exchange device, an outdoor heat exchanger, a first throttling mechanism, and a first bypass valve. The four-way valve includes first to fourth valve ports, and the compressor is connected to the first and third valve ports of the four-way valve; the gas-liquid separator is connected in series between the compressor and the first port of the four-way valve; each of the indoor heat exchange device and the outdoor heat exchanger has a first opening and a second opening, wherein the first opening of the indoor heat exchange device is connected to the second valve port of the four-way valve, and the second opening of the outdoor heat exchanger is connected to the fourth valve port of the four-way valve; the first throttling mechanism is connected in series between the second opening of the indoor heat exchange device and the first opening of the outdoor heat exchanger; the first throttling mechanism includes a first opening and a second opening, wherein the first opening of the first throttling mechanism is connected to the second opening of the indoor heat exchange device, and the second opening of the first throttling mechanism is connected to the first opening of the outdoor heat exchanger; and the first bypass valve is connected in parallel to the first throttling mechanism to selectively bypass the first throttling mechanism.

[0004] However, the indoor heat exchange device often carries a motor and an impeller connected to an output shaft of the motor. To ensure a normal power supply to the motor, it is necessary to arrange corresponding wires and power strips indoors, which extends a construction period and affects indoor aesthetics, leaving room for improvement. SUMMARY

[0005] In order to address issues in the related art, where a mounting of the indoor heat exchange device requires an arrangement of wires and power strips indoors, extending the construction period and affecting indoor aesthetics, the present application provides a heating system.

[0006] The heating system provided by the present application adopts the following technical solutions.

[0007] A heating system includes an outdoor heat exchange device and an indoor heat exchange device, wherein the outdoor heat exchange device includes a plate heat exchanger, and the indoor heat exchange device includes a casing, heat exchange tubes, a heat exchange fan, and a storage battery; the heat exchange tubes, the heat exchange fan, and the storage battery are all mounted inside the casing, the heat exchange fan blows air towards the heat exchange tube, and the storage battery is electrically connected to and supplies power to the heat exchange fan;

[0008] a first circulation pipeline is connected between a liquid outlet of the heat exchange tube and a cold-side inlet of the plate heat exchanger, and a water pump, which delivers a liquid in the heat exchange tube to the plate heat exchanger, is connected in series to the first circulation pipeline; and

[0009] a second circulation pipeline is connected between a cold-side outlet of the plate heat exchanger and a liquid inlet of the heat exchange tube, a turbine generator is connected in series to the second circulation pipeline, and the turbine generator is electrically connected to the storage battery and stores generated electricity in the storage battery.

[0010] By adopting the above technical solution, in practical use, the water pump draws a liquid in the heat exchange tube and feeds the liquid to the plate heat exchanger. At the same time, the outdoor heat exchange device can generate heat, which heats the liquid supplied by the water pump through the plate heat exchanger. Subsequently, a heated liquid enters the second circulation pipeline and flows through the turbine generator, causing the turbine generator to operate. At this point, the turbine generator generates electricity, which is supplied to and stored in the storage battery. Finally, the storage battery supplies power to the heat exchange fan, which drives air to flow towards the heat exchange tube, and the heat exchange tube performs heat exchange on a flowing air, such that air at an appropriate temperature is delivered indoors. In this way, a need for arranging wires and power strips indoors is reduced, the construction period of the heating system is shortened, and the indoor aesthetics is maintained.

[0011] Preferably, a water tank is connected in series to a portion of the first circulation pipeline between the water pump and the heat exchange tube.

[0012] By adopting the above technical solution, the water tank is mounted between the water pump and the heat exchange tube, allowing the water pump to draw the liquid from the water tank, which helps to ensure a sufficiency of the liquid supply from the water pump and guarantees a heat exchange efficiency of the heating system and a power generation efficiency of the turbine generator.

[0013] Preferably, a heat exchange water pipe is submerged in the water tank, a water inlet of the heat exchange water pipe is connected to a municipal water pipe, and a water outlet of the heat exchange water pipe is connected to a domestic water pipe.

[0014] By adopting the above technical solution, the liquid that flows into the water tank after passing through the heat exchange tube still retains a certain amount of heat, which can be used to heat domestic water through the heat exchange water pipe, increasing a functionality of the heating system.

[0015] Preferably, the outdoor heat exchange device further includes a connecting pipeline, an expansion valve, an evaporator, and a compressor, wherein the expansion valve, the evaporator, and the compressor are connected in series to the connecting pipeline, and both ends of the connecting pipeline are respectively connected to two ports on a hot side of the plate heat exchanger.

[0016] By adopting the above technical solution, in practical use, the compressor draws a refrigerant (such as FreonRTM) from the connecting pipeline and compresses the refrigerant to form a high-temperature and high-pressure gaseous refrigerant. The high-temperature and high-pressure gaseous refrigerant flows through the plate heat exchanger and transfers heat to the liquid supplied by the water pump. Then, the high-temperature and high-pressure gaseous refrigerant is transformed into a high-temperature and high-pressure liquid refrigerant. Subsequently, the high-temperatureand high-pressure liquid refrigerant flows through the expansion valve to be decompressed and cooled, and then enters the evaporator, where the high-temperatureand high-pressure liquid refrigerant absorbs external heat and turns back into a gas. Finally, the gaseous refrigerant is supplied to the compressor, moving in cycles, thereby accomplishing the heating process.

[0017] Preferably, the turbine generator is located inside the casing.

[0018] By adopting the above technical solution, the turbine generator is placed inside the casing, further reducing a need for electrical connections for the indoor heat exchange device.

[0019] Preferably, a water inlet of the turbine generator is formed in the second circulation pipeline away from the liquid inlet of the heat exchange tube, and the water inlet of the turbine generator is arranged to face downward.

[0020] By adopting the above technical solution, in practical use, under an action of the water pump, the liquid flows through the second circulation pipeline towards the turbine generator. Since the water inlet of the turbine generator is arranged to face downward, when the system is turned on, the liquid gradually rises at the water inlet of the turbine generator. At this time, bubbles in the liquid will rise and break, and an amount of bubbles in the liquid can be reduced, thereby reducing a cavitation caused by bubbles in the liquid striking on a turbine of the turbine generator and helping to extend a service life of the turbine generator.

[0021] Preferably, an upper side of the casing is fixed to a roof, and an elastic suspension frame is mounted inside the casing; an upper side of the elastic suspension frame is fixed to an upper side wall of the casing, and the turbine generator is mounted on a lower side of the elastic suspension frame.

[0022] By adopting the above technical solution, the turbine generator is mounted on the elastic suspension frame, which can block vibrations generated by the turbine generator during operation from being transmitted to the casing. This provides shock absorption for the turbine generator. In addition, since the upper side of the casing is fixed to the roof, the upper side of the casing has strong stability, which helps to reduce an intensity of vibrations from the casing and reduce a noise generated by the turbine generator.

[0023] Preferably, the elastic suspension frame includes two first mounting plates arranged opposite to each other, each of the two first mounting plates is defined with a mounting hole, and the turbine generator includes a water inlet pipe and a water outlet pipe; and the water inlet pipe and the drainage pipe pass through two mounting holes, respectively.

[0024] By adopting the above technical solution, the water inlet pipe and the water outlet pipe pass through the two mounting holes, facilitating a mounting of the turbine generator. Once the water inlet pipe and the water outlet pipe are connected to the second circulation pipeline, the turbine generator is less likely to fall off from the elastic suspension frame.

[0025] Preferably, the elastic suspension frame further includes a second mounting plate, and a mounting post is fixed to one side of the turbine generator away from the turbine; and the mounting post penetrates through the second mounting plate.

[0026] By adopting the above technical solution, the stability of the turbine generator mounted on the elastic suspension frame is improved.

[0027] Preferably, a soundproof cover is arranged inside the casing, the soundproof cover covers the turbine generator.

[0028] By adopting the above technical solution, the soundproof cover covers the turbine generator to reduce a transmission of noise generated by the turbine generator to the outside, thereby minimizing disruption to a daily life of a user.

[0029] Preferably, ventilation holes are formed in both opposite sides of the soundproof cover.

[0030] By adopting the above technical solution, in practical use, an airflow can circulate inside the soundproof cover through the ventilation holes, thereby cooling the turbine generator, which helps to ensure a normal cooling operation of the turbine generator. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0039] The present application will be further described in detail below with reference to the drawings.

[0040] Embodiments of the present application disclose a heating system.

[0041] Embodiment 1:

[0042] Referring to Figures 1 and 2, the heating system includes an outdoor heat exchange device 1 and an indoor heat exchange device 2. The indoor heat exchange device 2 includes a casing 21, a radiator 22, a heat exchange fan 23, and a storage battery 24 (see Figure 3). The radiator 22, the heat exchange fan 23, and the storage battery 24 are all mounted inside the casing 21. The heat exchange fan 23 flows air towards the radiator 22, and the storage battery 24 is electrically connected to and supplies power to the heat exchange fan 23. The outdoor heat exchange device 1 includes a plate heat exchanger 11. A first circulation pipeline 3 is connected between a liquid outlet of the radiator 22 and a cold-side inlet of the plate heat exchanger 11. A water pump 31, which delivers a liquid in the radiator 22 to the plate heat exchanger 11, is connected in series to the first circulation pipeline 3. A water tank 32 is connected in series to a portion of the first circulation pipeline 3 between the water pump 31 and the radiator 22. The indoor heat exchange device 2 further includes a turbine generator 25 mounted inside the casing 21. A second circulation pipeline 4 is connected between a cold-side outlet of the plate heat exchanger 11 and a liquid inlet of the radiator 22. The turbine generator 25 is connected in series to the second circulation pipeline 4. A water inlet of the turbine generator 25 is located on the second circulation pipeline 4 away from a liquid inlet of each heat exchange tube 222. The turbine generator 25 is electrically connected to the storage battery 24 and stores generated electricity in the storage battery 24.

[0043] In operation, a heat exchange liquid medium, which may be water, is placed in the water tank 32. When the heating system is running, the water pump 31 draws a liquid from the water tank 32 and supplies the liquid to the plate heat exchanger 11. Simultaneously, the outdoor heat exchange device 1 can generate heat, and the plate heat exchanger 11 heats the liquid supplied by the water pump 31. A heated liquid then enters the second circulation pipeline 4 and flows through the turbine generator 25, causing the turbine generator 25 to operate. At this point, the turbine generator 25 generates electricity, which is supplied to and stored in the storage battery 24. Finally, the storage battery 24 supplies power to the heat exchange fan 23, which drives air to flow towards the radiator 22, and the radiator 22 performs heat exchange on a flowing air, such that air at an appropriate temperature is delivered indoors.

[0044] Referring to Figures 2 and 3, specifically, a top side and a bottom side of the casing 21 are rectangular. One side wall of the casing 21 in a width direction is hollow and forms an exhaust side 211. A side wall of the casing 21 away from the exhaust side 211 is provided with an air inlet 212. The heat exchange fan 23 is fixedly mounted inside the casing 21 and located at the air inlet 212. There is one air inlet 212 on each of both sides of the casing 21 along a length direction, with the turbine generator 25 being located between two air inlets 212. The heat exchange fan 23 draws air outside the casing 21 through the air inlets 212 into the casing 21 and exhausts the air through the exhaust side 211. Inside the casing 21, the radiator 22 is positioned between the exhaust side 211 and the heat exchange fan 23. The radiator 22 includes two main pipelines 221 and heat exchange tubes 222 located between the two main pipelines 221. Both main pipelines 221 are arranged to incline upward from the air inlet 212 toward the exhaust side 211 and are positioned on both sides of the casing 21 in parallel to each other in a length direction. The heat exchange tubes 222 are flat, with both ends connected to the two main pipelines 221 respectively, and a plurality of heat exchange tubes 222 are evenly spaced in an inclination direction of the main pipelines 221. Both ends of each main pipeline 221 are sealed. A partition plate is fixed in a middle inside one of the main pipelines 221 to partition an inside of the corresponding pipeline 221 into two chambers. The two chambers are connected to the first circulation pipeline 3 and the second circulation pipeline 4, respectively.

[0045] Referring to Figure 1, a heat exchange water pipe 5 is submerged in the water tank 32. A water inlet of the heat exchange water pipe 5 is connected to a municipal water pipe, and a water outlet of the heat exchange water pipe 5 is connected to a domestic water pipe. In this embodiment, the heat exchange water pipe 5 is coiled inside the water tank 32, or may also be bent continuously to extend a flow path of domestic water inside the water tank 32, thereby improving a heat exchange efficiency.

[0046] Additionally, the outdoor heat exchange device 1 further includes a connecting pipeline 12, an expansion valve 13, an evaporator 14, and a compressor 15. The expansion valve 13, the evaporator 14, and the compressor 15 are sequentially connected in series to the connecting pipeline 12. Both ends of the connecting pipeline 12 are connected to two ports on a hot side of the plate heat exchanger 11.

[0047] An implementation principle of the heating system disclosed in this embodiment of the present application is as follows: in practical use, water can be injected into the water tank 32, and a refrigerant (such as FreonRTM) is placed in the connecting pipeline 12. During operation, the water pump 31 draws the liquid from the water tank 32 and supplies the liquid to the plate heat exchanger 11. The compressor 15 draws the refrigerant from the connecting pipeline 12, compresses the refrigerant into a high-temperature and high-pressure gaseous refrigerant. The high-temperature and high-pressure gaseous refrigerant flows through the plate heat exchanger 11 and transfers heat to the liquid supplied by the water pump 31. Then, the high-temperature and high-pressure gaseous refrigerant is transformed into a liquid refrigerant. Subsequently, the liquid refrigerant flows through the expansion valve 13 to be decompressed and cooled, and then enters the evaporate 14, where the liquid refrigerant absorbs external heat and turns back into a gas. Finally, the gaseous refrigerant is supplied to the compressor 15 for continuous cycling.

[0048] Meanwhile, a heated liquid enters the second circulation pipeline 4 and flows through the turbine generator 25, causing the turbine generator 25 to operate. At this time, the turbine generator 25 generates electricity, which is supplied to and stored to the storage battery 24. Afterward, the storage battery 24 supplies power to the heat exchange fan 23, which drives air to flow towards the radiator 22. The radiator 22 performs heat exchange on the flowing air, such that air at an appropriate temperature is delivered indoors.

[0049] Embodiment 2:

[0050] Referring to Figures 4 and 5, this embodiment differs from Embodiment 1 in that an upper side of the casing 21 is fixed to a roof by fasteners. An elastic suspension frame 6 (see Figure 6) is arranged inside the casing 21; an upper side of the elastic suspension frame 6 is fixed to an upper side wall of the casing 21 by fasteners. The turbine generator 25 is mounted on a lower side of the elastic suspension frame 6.

[0051] Referring to Figures 6 and 7, specifically, the elastic suspension frame 6 is made of rubber. The elastic suspension frame 6 includes two first mounting plates 61 located at a lower side of the elastic suspension frame 6, which are arranged opposite to each other. Each of the two first mounting plates 61 is defined with a mounting hole 611. The turbine generator 25 includes a water inlet pipe 251 and a water outlet pipe 252, which pass through the two mounting holes 611 respectively, the turbine generator 25 is connected in series to the second circulation pipeline 4 through the water inlet pipe 251 and the water outlet pipe 252. The elastic suspension frame 6 further includes a second mounting plate 62, a mounting post 253 is fixed on one side of the turbine generator 25 away from a turbine, and the mounting post 253 penetrates through the second mounting plate 62. Additionally, heights of the two mounting holes 611 are different, allowing a water inlet of the turbine generator 25 to be inclined downward. When the system is turned on, under an action of the water pump 31, the liquid moves along the second 5 circulation pipeline 4 towards the turbine generator 25, and gradually rises at the water inlet of the turbine generator 25. At this point, bubbles in the liquid will rise and burst, thereby reducing an amount of bubbles in the liquid and reducing a cavitation caused by bubbles in the liquid striking on a turbine of the turbine generator 25.

[0052] To reduce a noise generated by the turbine generator 25 from being transmitted 10 outward, a soundproof cover 7 is arranged inside the casing 21, the soundproof cover 7 covers the turbine generator 25. In addition, ventilation holes 71 are formed in both opposite sides of the soundproof cover 7 in a width direction of the casing 21, and a side of the soundproof cover 7 away from the radiator 22 is connected to an outside of the casing 21. In this embodiment, the soundproof cover 7 is made of porous sound-absorbing cotton. 15
