Description

Technical Field

[0001] This invention relates to the field of ground source heat pump air conditioning units, specifically to waste heat recovery type ground source heat pump air conditioning units. Background Technology

[0002] Ground source heat pump air conditioning units utilize ground source heat energy for indoor temperature regulation, generating a significant amount of waste heat during operation. Waste heat recovery type ground source heat pump air conditioning units can effectively capture and store this waste heat, then use it to supply heating equipment, achieving efficient heating functionality.

[0003] The existing waste heat recovery type ground source heat pump air conditioning unit works by: introducing the waste heat generated by the heat pump into the water tank, storing heat by heating the water in the tank, and recovering and reusing the waste heat by removing the water from the tank.

[0004] While this method can achieve waste heat recovery and reuse, the following problems still exist: First, since waste heat recovery and reuse relies on hot water in the transport tank, the water in the tank is always in a flowing state, and some water may be discharged before it is fully heated, resulting in a low waste heat recovery and reuse rate; Second, the amount of waste heat generated varies when the air conditioner is running at different preset temperatures, and the heating time of the water in the tank is difficult to adjust, which may result in the water discharged from the tank being too hot, causing energy waste, or the water discharged from the tank being too cold, resulting in incomplete heating. Summary of the Invention

A third rotating groove is located outside the second fixed box, and a third rotating ring is rotatably connected inside the third rotating groove. A plurality of second water distribution chambers are located inside the third rotating ring. Each second water distribution chamber corresponds to a heating box, and each second water distribution chamber is connected to the heating box by a second water guide pipe. Each second water distribution chamber has a water outlet hole near the second fixed box. The water collection chamber has a second water outlet notch near the second water distribution chamber.

The water to be heated enters through the water inlet pipe, then passes through the water distribution tank, the heating box, and the water outlet tank, and finally flows out from the water outlet pipe. During this process, the water is stored in the water storage chamber of the water distribution tank. When the heating box rotates until the water inlet is aligned with the first water inlet notch and the water outlet is aligned with the second water outlet notch, the water to be heated enters the heating box for heating. When the heating box rotates until the water inlet is disengaged from the first water inlet notch and the water outlet is disengaged from the second water outlet notch, the hot water is stored in the heating box and no longer flows out, ensuring that the hot water is fully heated. When the heating box rotates until the water inlet is aligned with the first water inlet notch again and the water outlet is aligned with the second water outlet notch again, the hot water is discharged.

[0020] This invention features a waste heat recovery device mounted on a fixed frame. A heating tank is rotatably mounted within the housing. Water inflow and outflow within the heating tank are controlled via inlet and outlet structures, extending the residence time of the water to be heated. Based on the stable operation of the actual air conditioning system, a speed-regulating structure further controls the residence time of the water in the heating tank. This invention replaces the existing technology of directly introducing waste heat air into the water tank for waste heat storage. This invention not only allows for a longer residence time of the water in the heating tank but also adjusts the residence time based on the actual waste heat generated. This invention offers higher waste heat recovery efficiency and strong practicality. Attached Figure Description

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0034] like Figures 2-9As shown, this embodiment proposes a waste heat recovery type ground source heat pump air conditioning unit, the structure of which includes a fixed frame 1. In this embodiment, the condenser 2, evaporator 3, compressor 4, and waste heat recovery device are mounted on the fixed frame 1. The condenser 2 is connected to the air conditioner, and the evaporator 3 is connected to the underground pipe system, used to transfer heat to the ground or transfer heat from the ground into the air conditioner. The waste heat recovery device includes a housing 5, with an inlet pipe 21, an outlet pipe 22, a water inlet pipe 51, and a water outlet pipe 52 all mounted on the housing 5. The inlet pipe 21 and the outlet pipe 22 are connected to the condenser 2, and several heating boxes 6 are rotatably mounted inside the housing 5. A speed control structure is located inside the housing 5 to adjust the rotation speed of the heating boxes 6. Each heating box 6 is connected to the inlet pipe 21 and the outlet pipe 22, and a hot water pipe 61 is located inside the heating box 6. The water inlet structure is located between the hot water pipe 61 and the water inlet pipe 51, used to allow water to flow into the hot water pipe 61 when the heating tank 6 is close to the water inlet pipe 51, and to stop the water inlet pipe 51 from flowing into the hot water pipe 61 when the heating tank 6 is away from the water inlet pipe 51. The water outlet structure is located between the hot water pipe 61 and the water outlet pipe 52, used to allow water to flow out of the hot water pipe 61 into the water inlet pipe 51 when the heating tank 6 is close to the water outlet pipe 52, and to stop the water outlet pipe 61 from flowing into the water inlet pipe 51 when the heating tank 6 is away from the water inlet pipe 51.

[0035] The speed regulating structure in this embodiment includes a first speed regulating component 241 and a second speed regulating component 242. A speed regulating chamber 24 is disposed on the upper side of the housing 5. Both the first speed regulating component 241 and the second speed regulating component 242 are rotatably connected to the speed regulating chamber 24. Both the first speed regulating component 241 and the second speed regulating component 242 have a frustum-shaped structure. A transmission belt 2411 is rolled on the first speed regulating component 241 and the second speed regulating component 242. The shortest distances between the end of the first speed regulating component 241 furthest from the second speed regulating component 242 and the end of the second speed regulating component 242 furthest from the first speed regulating component 241 are equal. This ensures that when the transmission belt 2411 moves on the first speed regulating component 241 and the second speed regulating component 242, the transmission belt 2411 will not be too tight or too loose due to different positions, thus preventing the transmission belt 2411 from disengaging from the first speed regulating component 241 and the second speed regulating component 242. Since both the first speed regulating component 241 and the second speed regulating component 242 are frustum-shaped structures, the transmission ratio of the transmission belt 2411 on the first speed regulating component 241 and the second speed regulating component 242 changes depending on the position of the transmission belt 2411 on the first speed regulating component 241 and the second speed regulating component 242. Therefore, the speed of the second speed regulating component 242 can be changed by changing the position of the transmission belt 2411 on the first speed regulating component 241 and the second speed regulating component 242.

[0036] In this embodiment, the limiting member 94 is sleeved on the transmission belt 2411. The first lead screw 91 and the second lead screw 92 are rotatably disposed within the speed regulating chamber 24. The limiting member 94 is threadedly connected to both the first lead screw 91 and the second lead screw 92. The synchronous belt 93 is connected to both the first lead screw 91 and the second lead screw 92 to synchronize their rotation. The movement of the limiting member 94 is controlled by the first lead screw 91 and the second lead screw 92. Since the rotational stroke of the first lead screw 91 and the second lead screw 92 is much greater than the movement stroke of the limiting member 94, controlling the movement of the limiting member 94 by rotating the first lead screw 91 and the second lead screw 92 is more precise and reliable.

[0037] In this embodiment, the first drive motor 243 and the second drive motor 244 are fixedly mounted inside the speed regulating chamber 24. The first gear 2432 is fixedly mounted on the first speed regulating component 241, and the second gear 2431 is rotatably mounted inside the speed regulating chamber 24. The first gear 2432 and the second gear 2431 mesh with each other. The output shaft of the first drive motor 243 is fixedly connected to the second gear 2431. The third gear 2442 is fixedly mounted on the first lead screw 91, and the fourth gear 2441 is rotatably mounted inside the speed regulating chamber 24. The third gear 2442 meshes with the fourth gear 2441, and the output shaft of the second drive motor 244 is fixedly connected to the fourth gear 2441. This design facilitates the installation of the first drive motor 243 and the second drive motor 244, and facilitates their control of the movement of the first speed regulating component 241 and the sliding component.

[0038] In this embodiment, the air guiding chamber 23 is located on the upper side of the speed regulating chamber 24, the air inlet pipe 21 is located on the side wall of the air guiding chamber 23, several first air guiding pipes 231 are fixedly located at the bottom of the air guiding chamber 23, and the air distribution chamber 25 is located on the lower side of the speed regulating chamber 24. Each first air guiding pipe 231 is connected to the air distribution chamber 25. In this embodiment, by connecting multiple first air guiding pipes 231 to the air distribution chamber 25, the generated waste heat can be accelerated to flow to the air distribution chamber 25, reducing the loss of waste heat during operation.

[0039] In this embodiment, the shell 5 is a cylindrical structure. A gas distribution chamber 251 is located within the gas distribution room 25. The top of the gas distribution chamber 251 is connected to the first air guide pipe 231. A limiting plate 252 is rotatably mounted at the lower end of the gas distribution chamber 251. Several second air guide pipes 253 are fixedly mounted at the lower end of the limiting plate 252. Each second air guide pipe 253 corresponds one-to-one with the heating box 6, and the second air guide pipe 253 is connected to the top of the heating box 6. This design of the gas distribution chamber 25 ensures that when the limiting plate 252 rotates, the hot air in the gas distribution chamber 251 can still enter the heating box 6 through the second air guide pipes 253, and effectively reduces heat loss caused by hot air leakage.

[0040] The water inlet structure in this embodiment includes a water distribution tank, and a water inlet pipe 51 is disposed on the top of the housing 5. A first speed regulating component 241 is sleeved inside the water inlet pipe 51 to reduce the impact of the rotation of the heating box 6 on the water inlet pipe 51. The water distribution tank is disposed on the lower side of each heating box 6. The water distribution tank includes a first fixed box 71, a water storage cavity 711 disposed inside the first fixed box 71, the first fixed box 71 is fixedly connected to the housing 5, and a second rotating groove 713 is disposed on the side wall of the first fixed box 71. A second rotating ring 72 is rotatably disposed in the second rotating groove 713 to prevent the second rotating ring 72 from rotating off-center. Several first water distribution chambers 721 are disposed within the second rotating ring 72. Water inlets 722 are located in each first water distribution chamber 721 near the first fixed box 71. First water outlets 712 are located in the water storage chamber 711 near the first water distribution chambers 721. The projection plane of the water inlet 722 falls within the projection plane of the first water outlet 712. Each first water distribution chamber 721 corresponds to a heating box 6, and a first water guide pipe 62 connects the first water distribution chamber 721 to the heating box 6. When the second rotating ring 72 rotates to align the first water outlet 712 with the water inlet 722, hot water enters the first water distribution chamber 721 of the first water outlet 712 and then enters the heating box 6. When the second rotating ring 72 rotates to disengage the first water outlet 712 from the water inlet 722, hot water no longer enters the first water distribution chamber 721. This allows hot water to enter the heating tank 6 in stages, sequentially. When no water enters the heating tank 6, residual heat is used to heat the water, extending the heating time. In this embodiment, the area of ​​the first water outlet 712 is larger than the area of ​​the water inlet 722 to prolong the water intake time.

[0041] In this embodiment, the exhaust chamber 26 is disposed within the housing 5. The exhaust chamber 26 includes a first rotating ring 261, which is fixedly connected to the housing 5. A first rotating groove 2611 is disposed within the first rotating ring 261, and the cross-section of the first rotating groove 2611 is a convex structure to prevent the first rotating ring 261 from detaching from the first rotating groove 2611. A sealing ring 262 is rotatably disposed within the first rotating groove 2611, and a gap is provided between the sealing ring 262 and the bottom of the first rotating groove 2611. A third air guide pipe 263 is fixedly disposed between the side wall of each heating chamber 6 and the sealing ring 262. The exhaust pipe 22 is connected to the side wall of the first rotating ring 261. In this embodiment, the first rotating ring 261 can be designed as an upper ring and a lower ring, and the upper and lower rings can be fixedly connected by bolts, which facilitates the disassembly and installation of the sealing ring 262 within the first rotating ring 261. This design of the exhaust chamber 26 ensures that when the sealing ring 262 rotates relative to the first rotating groove 2611, the hot air gathered by the third air guide pipe 263 can be concentrated through the gap between the first rotating groove 2611 and the sealing ring 262, and then discharged through the third air guide pipe 263.

[0042] The water outlet structure in this embodiment includes a water outlet tank, which is located at the lower end of the water distribution tank. The water outlet tank includes a second fixed box 81, a water collection chamber 811 located inside the second fixed box 81, and a third rotating groove 813 located outside the second fixed box 81. A third rotating ring 82 is rotatably disposed within the third rotating groove 813 to prevent the third rotating ring 82 from deviating during rotation. Several second water distribution chambers 821 are disposed within the third rotating ring 82, each second water distribution chamber 821 corresponding to a heating box 6, and each second water distribution chamber 821 is connected to the heating box 6 by a second water guide pipe 63. Water outlet holes 822 are located on the side of each second water distribution chamber 821 near the second fixed box 81, and second water outlet notches 812 are located on the side of the water collection chamber 811 near the second water distribution chambers 821. The projection surface of the water outlet hole 822 falls within the projection surface of the second water outlet notch 812. When the third rotating ring 82 rotates to align the second water outlet notch 812 with the water outlet hole 822, the hot water in the heating tank 6 flows from the second water outlet notch 812 to the water outlet hole 822 and flows out from the water outlet pipe 52; when the third rotating ring 82 rotates to disengage the second water outlet notch 812 from the water outlet hole 822, the hot water cannot enter the water outlet hole 822 and remains in the hot water pipe 61 for heating, extending its heating time and improving the utilization rate of residual heat.

[0043] In this embodiment, the hot water pipe 61 is installed inside the heating box 6. The hot water pipe 61 is spirally distributed, and the first water guide pipe 62 and the second water guide pipe 63 are respectively connected to the two ends of the hot water pipe 61. The spiral distribution of the hot water pipe 61 increases the contact area between the hot water in the hot water pipe 61 and the air, allowing more water to receive more heat.

[0044] The working process of this embodiment is as follows: When waste heat recovery is required, the waste heat generated by the condenser 2 passes through the inlet pipe 21, the air guide chamber 23, the air distribution chamber 251, the heating box 6, and the outlet chamber 26, and finally flows out from the outlet pipe 22. The first drive motor 243 is started, and the first speed regulating component 241 rotates via the transmission belt 2411, driving the second speed regulating component 242 to rotate. The second speed regulating component 242 drives the limiting plate 252, the heating box 6, the first limiting ring, and the second limiting ring to rotate. The water to be heated enters from the inlet pipe 51, then passes through the water distribution tank, the heating box 6, and the outlet tank, and finally flows out from the outlet pipe 52. During this process, the water is stored in the water storage chamber 711 in the water distribution tank. When the heating tank 6 rotates, aligning the inlet hole 722 with the first inlet gap and the outlet hole 822 with the second outlet gap 812, the water to be heated enters the heating tank 6 for heating. When the heating tank 6 rotates, disengaging the inlet hole 722 from the first inlet gap and the outlet hole 822 from the second outlet gap 812, the hot water is stored in the heating tank 6 and no longer flows out, ensuring that the hot water is fully heated. When the heating tank 6 rotates again, aligning the inlet hole 722 with the first inlet gap and the outlet hole 822 with the second outlet gap 812, the hot water is discharged.

[0045] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
