Description

A heating system Technical Field

[0001] This application relates to the field of heating technology, and in particular to a heating system. Background Technology

[0002] In the face of tightening energy supplies and increasingly stringent environmental protection requirements, people are constantly seeking new energy sources that are both energy-efficient and environmentally friendly, and heat pumps are one such new energy source. Because heat pumps can transfer low-temperature heat energy to high-temperature heat energy, they can make extensive use of heat from natural resources and waste heat resources, effectively saving primary energy required for both residential and industrial use.

[0003] A patent with publication number CN103307800B discloses a heat pump system, including a compressor, a four-way valve, a gas-liquid separator, an indoor heat exchanger, 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 opening of the four-way valve. Each of the indoor heat exchanger and the outdoor heat exchanger has first and second openings, with the first opening of the indoor heat exchanger connected to the second valve port of the four-way valve and the second opening of the outdoor heat exchanger 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 exchanger and the first opening of the outdoor heat exchanger. The first throttling mechanism includes first and second openings, with the first opening of the first throttling mechanism connected to the second opening of the indoor heat exchanger and the second opening of the first throttling mechanism connected to the first opening of the outdoor heat exchanger. The first bypass valve is connected in parallel with the first throttling mechanism to selectively bypass the first throttling mechanism.

[0004] However, indoor heat exchange devices often carry motors and impellers connected to the motor output shaft. To ensure the motor is properly powered, corresponding wires and power strips need to be laid out indoors, which prolongs the construction period and affects the aesthetics of the room, and there are areas for improvement. Summary of the Invention

[0005] In order to improve the problem that the installation of indoor heat exchange devices in related technologies requires the laying of electrical wires and power strips indoors, which prolongs the construction period and affects the aesthetics of the room, this application provides a heating system.

[0006] The heating system provided in this application adopts the following technical solution:

[0007] A heating system includes an outdoor heat exchange device and an indoor heat exchange device. The outdoor heat exchange device includes a plate heat exchanger, and the indoor heat exchange device includes a housing, heat exchange tubes, a heat exchange fan, and a battery. The heat exchange tubes, the heat exchange fan, and the battery are all installed inside the housing. The heat exchange fan blows air towards the heat exchange tubes, and the battery is electrically connected to the heat exchange fan and supplies power to the heat exchange fan.

[0008] A first circulation pipeline is connected between the outlet of the heat exchange tube and the cold side inlet of the plate heat exchanger. A water pump for transporting the water in the heat exchange tube to the plate heat exchanger is connected in series on the first circulation pipeline.

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

[0010] By adopting the above technical solution, in practical application, the water pump draws liquid from the heat exchange tubes and feeds it to the plate heat exchanger; simultaneously, the outdoor heat exchange device can generate heat, and the liquid delivered by the water pump is heated by the plate heat exchanger; subsequently, the heated liquid enters the second circulation pipeline and flows through the turbine generator, causing the turbine generator to operate; at this time, the turbine generator generates electricity and supplies the power to the battery for storage; finally, the battery supplies power to the heat exchange fan, which drives the airflow, causing the air to be blown towards the heat exchange tubes, where the heat exchange tubes exchange heat with the flowing air, delivering air at a suitable temperature into the room. This method reduces the need for indoor wiring and power strips, shortens the construction period of the heating system, and helps to ensure the aesthetics of the interior.

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

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

[0013] Preferably, the water tank is not filled with a hot water exchange pipe, the inlet of the hot water exchange pipe is used to connect to the municipal water pipe, and the outlet of the hot water exchange pipe is used to connect to the domestic water pipe.

[0014] By adopting the above technical solution, the liquid flowing into the water tank after passing through the heat exchange pipe still has a certain temperature, which can be used to heat domestic water through the heat exchange pipe, thereby increasing the function of the heating system.

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

[0016] By adopting the above technical solution, in practical application, the compressor draws refrigerant (such as Freon) from the connecting pipeline and pressurizes it to form a high-temperature, high-pressure gaseous refrigerant. The high-temperature, high-pressure gaseous refrigerant passes through a plate heat exchanger, transferring heat to the liquid pumped by the water pump. Then, the high-temperature, high-pressure gaseous refrigerant will be transformed into a liquid refrigerant. After that, the high-temperature, high-pressure liquid refrigerant will be depressurized and cooled through an expansion valve, and then enter the evaporator, where it absorbs external heat and transforms back into a gaseous state. Finally, the gaseous refrigerant will be supplied to the compressor, and the cycle will repeat, thereby achieving the heating function.

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

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

[0019] Preferably, the water inlet of the turbine generator is located away from the liquid inlet of the heat exchange tube on the second circulation pipeline, and the water inlet of the turbine generator is arranged downwards.

[0020] By adopting the above technical solution, in practical applications, under the action of the water pump, the liquid moves towards the turbine generator along the second circulation pipeline. Since the water inlet of the turbine generator is set downwards, when the generator is started, the liquid will gradually rise at the water inlet of the turbine generator. At this time, the bubbles will rise and break, and the amount of bubbles in the liquid will be reduced, thereby weakening the cavitation phenomenon caused by the bubbles in the liquid hitting the turbine of the turbine generator, which helps to extend the service life of the turbine generator.

[0021] Preferably, the upper side of the housing is fixed to the roof, an elastic hoisting frame is provided inside the housing, the upper side of the elastic hoisting frame is fixed to the upper side wall of the housing, and the turbine generator is installed on the lower side of the elastic hoisting frame.

[0022] By adopting the above technical solution, the turbine generator is installed on a flexible lifting frame. The flexible lifting frame can prevent the vibration generated by the turbine generator from being transmitted to the casing, thereby reducing the vibration of the turbine generator. Furthermore, the upper side of the casing is fixed to the roof, which gives the upper side of the casing strong stability. This helps to reduce the vibration intensity of the casing and also helps to reduce the noise generated by the turbine generator.

[0023] Preferably, the elastic hoisting frame includes two opposing first mounting plates, each with mounting holes, and the turbine generator includes an inlet pipe and a drain pipe, each passing through one of the two mounting holes.

[0024] By adopting the above technical solution, two installation holes are respectively provided for the water inlet pipe and the water outlet pipe, which facilitates the installation of the turbine generator. Furthermore, after the water inlet pipe and the water outlet pipe of the turbine generator are connected to the second circulation pipeline, the turbine generator will be less likely to fall off the flexible hoisting frame.

[0025] Preferably, the elastic hoisting frame further includes a second mounting plate, and a mounting column is fixed to the side of the turbine generator opposite to its turbine, the mounting column penetrating the second mounting plate.

[0026] By adopting the above technical solutions, the stability of the turbine generator installed on the flexible lifting frame can be improved.

[0027] Preferably, a soundproof cover is provided inside the housing, and the soundproof cover covers the turbine generator.

[0028] By adopting the above technical solution, the turbine generator is covered by a soundproof enclosure, which reduces the outward transmission of noise generated by the turbine generator and reduces the interference with the user's life.

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

[0030] By adopting the above technical solution, in practical applications, airflow can circulate through the ventilation holes inside the soundproof enclosure, thereby dissipating heat from the turbine generator and helping to ensure the normal operation of the turbine generator's heat dissipation function.

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

[0040] This application discloses a heating system.

[0041] Example 1:

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

[0043] In operation, the water tank 32 contains a heat exchange liquid medium, which can be water. During operation, the water pump 31 draws liquid from the water tank 32 and feeds it to the plate heat exchanger 11; simultaneously, the outdoor heat exchange device 1 generates heat and heats the liquid supplied by the water pump 31 via the plate heat exchanger 11; then, the 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 and supplies the power to the storage battery 24, where it is stored; finally, the storage battery 24 supplies power to the heat exchange fan 23, which drives the airflow, causing the air to blow towards the radiator 22, where the radiator 22 exchanges heat with the flowing air, thereby delivering air at a suitable temperature into the room.

[0044] Referring to Figures 2 and 3, specifically, the upper and lower sides of the casing 21 are rectangular. One side wall of the casing 21 in the width direction is hollowed out to form an exhaust side 211. An air inlet 212 is opened on the side wall of the casing 21 away from the exhaust side 211. The heat exchange fan 23 is fixedly installed inside the casing 21 and located at the air inlet 212. There is one air inlet 212 on each side of the casing 21 in the length direction. The turbine generator 25 is located between the two air inlets 212. The heat exchange fan 23 draws air from outside the casing 21 into the casing 21 through the air inlet 212 and discharges it through the exhaust side 211. A radiator 22 is installed inside the casing 21, and the radiator 22 is located between the exhaust side 211 and the heat exchange fan 23. The radiator 22 includes two main pipes 221 and a heat exchange tube 222 located between the two main pipes 221. Both main pipes 221 are inclined upwards from the air inlet 212 towards the exhaust side 211, and are located on opposite sides of the casing 21 along its length and are parallel to each other. The heat exchange tube 222 is flat, with both ends connected to the two main pipes 221, and several heat exchange tubes 222 are evenly spaced along the inclined direction of the main pipes 221. Both ends of each main pipe 221 are closed. A partition plate is fixed in the middle of one of the main pipes 221, dividing the corresponding main pipe 221 into two cavities. The two cavities are respectively connected to the first circulation pipe 3 and the second circulation pipe 4.

[0045] Referring to Figure 1, the hot water exchange pipe 5 is submerged in the water tank 32. The inlet of the hot water exchange pipe 5 is used to connect to the municipal water pipe, and the outlet of the hot water exchange pipe 5 is used to connect to the domestic water pipe. In this embodiment, the hot water exchange pipe 5 is spiral-shaped inside the water tank 32, or it can be continuously bent, to extend the flow path of domestic water in the water tank 32 and improve the heat exchange effect.

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

[0047] The implementation principle of a heating system according to an embodiment of this application is as follows: In actual use, water can be injected into the water tank 32, and refrigerant (such as Freon) is placed in the connecting pipe 12. During operation, the water pump 31 draws liquid from the water tank 32 and feeds it to the plate heat exchanger 11; the compressor 15 draws refrigerant from the connecting pipe 12 and pressurizes it to form a high-temperature, high-pressure gaseous refrigerant. The high-temperature, high-pressure gaseous refrigerant passes through the plate heat exchanger 11 and transfers heat to the liquid transported by the water pump 31; then, the high-temperature, high-pressure gaseous refrigerant will be converted into liquid refrigerant; afterwards, the liquid refrigerant will be depressurized and cooled through the expansion valve 13, and then enter the evaporator 14, where it absorbs external heat and is converted back into gaseous state; finally, the gaseous refrigerant will be supplied to the compressor 15, and the cycle repeats.

[0048] Meanwhile, the heated liquid enters the second circulation pipe 4 and flows through the turbine generator 25, causing the turbine generator 25 to operate. At this time, the turbine generator 25 generates electricity and supplies the power to the storage battery 24, where it is stored. Afterward, the storage battery 24 supplies power to the heat exchange fan 23, which drives the airflow, causing the air to blow towards the radiator 22. The radiator 22 exchanges heat with the flowing air, thereby delivering air at a suitable temperature into the room.

[0049] Example 2:

[0050] Referring to Figures 4 and 5, the difference between this embodiment and Embodiment 1 is that the upper side of the housing 21 is fixed to the roof by fasteners, and an elastic hoisting frame 6 (Figure 6) is provided inside the housing 21. The upper side of the elastic hoisting frame 6 is fixed to the upper side wall of the housing 21 by fasteners, and the turbine generator 25 is installed on the lower side of the elastic hoisting frame 6.

[0051] Referring to Figures 6 and 7, specifically, the flexible lifting frame 6 is made of rubber. The flexible lifting frame 6 includes two first mounting plates 61 located on the lower side, arranged opposite each other. Each first mounting plate 61 has mounting holes 611. The turbine generator 25 includes an inlet pipe 251 and a drain 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 via the inlet pipe 251 and the drain pipe 252. The flexible lifting frame 6 also includes a second mounting plate 62. A mounting column 253 is fixed to the side of the turbine generator 25 away from its turbine, and the mounting column 253 passes through the second mounting plate 62. Furthermore, the two mounting holes 611 are at different heights, causing the water inlet of the turbine generator 25 to be tilted downwards. When the machine is started, under the action of the water pump 31, the liquid moves along the second circulation pipeline 4 to the turbine generator 25. The liquid will gradually rise at the water inlet of the turbine generator 25. At this time, the bubbles will rise and break, and the amount of bubbles in the liquid will be reduced, thereby weakening the cavitation phenomenon caused by the bubbles in the liquid hitting the turbine of the turbine generator 25.

[0052] To reduce the outward transmission of noise generated by the turbine generator 25, a soundproof cover 7 is provided inside the housing 21. The soundproof cover 7 covers the turbine generator 25, and ventilation holes 71 are provided on both opposite sides of the housing 21 in the width direction. The side of the soundproof cover 7 away from the radiator 22 is connected to the outside of the housing 21. In this embodiment, the soundproof cover 7 is made of porous sound-absorbing cotton.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
