[0002] The ground source heat pump air conditioner uses ground source heat energy to adjust the indoor temperature, and it will generate a lot of waste heat during operation. The waste heat recovery ground source heat pump air conditioner can effectively capture this waste heat and store it, and then use it to supply heating equipment to achieve efficient heating function.

[0003] The existing waste heat recovery type ground source heat pump air conditioning unit works as follows: the waste heat air generated by the heat pump is introduced into the water tank, the heat is stored by adding moisture in the water tank, and the waste heat is recovered and reused by exporting the moisture in the water tank.

DETAILED DESCRIPTION

[0021] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figure 2~Figure 9As shown, this embodiment proposes a waste heat recovery type ground source heat pump air conditioning unit, and its structure includes a fixed frame 1. The condenser 2, evaporator 3, compressor 4 and waste heat recovery device in this embodiment are arranged on the fixed frame 1. Among them, the condenser 2 is connected to the air conditioner, and the evaporator 3 is connected to the buried pipe system, which is used to introduce heat into the ground or introduce the heat underneath into the air conditioner. The waste heat recovery device includes a shell 5, an air inlet pipe 21, an air outlet pipe 22, a water inlet pipe 51 and a water outlet pipe 52 are all arranged on the shell 5, the air inlet pipe 21 and the air outlet pipe 22 are connected to the condenser 2, and a plurality of heating boxes 6 are rotatably arranged in the shell 5. The speed regulating structure is arranged in the shell 5, which is used to adjust the rotation speed of the heating box 6. Each heating box 6 is connected to the air inlet pipe 21 and the air outlet pipe 22, and the hot water pipe 61 is arranged in the heating box 6. The water inlet structure is disposed between the hot water pipe 61 and the water inlet pipe 51, and is used for the water inlet pipe 51 to inlet water into the hot water pipe 61 when the heating box 6 approaches the water inlet pipe 51, and for the water inlet pipe 51 to stop inletting water into the hot water pipe 61 when the heating box 6 is away from the water inlet pipe 51. The water outlet structure is disposed between the hot water pipe 61 and the water outlet pipe 52, and is used for the hot water pipe 61 to discharge water into the water inlet pipe 51 when the heating box 6 approaches the water outlet pipe 52, and for the hot water pipe 61 to stop discharge water into the water inlet pipe 51 when the heating box 6 is away from the water inlet pipe 51.

[0023] The speed regulating structure in this embodiment includes a first speed regulating member 241 and a second speed regulating member 242. The speed regulating chamber 24 is arranged on the upper side of the housing 5. The first speed regulating member 241 and the second speed regulating member 242 are both rotatably connected to the speed regulating chamber 24. The first speed regulating member 241 and the second speed regulating member 242 are both truncated cone-shaped structures. The transmission belt 2411 is rollingly arranged on the first speed regulating member 241 and the second speed regulating member 242. The shortest distance between the first speed regulating member 241 and the second speed regulating member 242 is equal to the shortest distance between the first speed regulating member 241 and the second speed regulating member 242, so as to ensure that when the transmission belt 2411 moves on the first speed regulating member 241 and the second speed regulating member 242, the transmission belt 2411 will not be too tight or too loose due to different positions, which will affect the transmission belt 2411 to separate from the first speed regulating member 241 and the second speed regulating member 242. Since the first speed regulating member 241 and the second speed regulating member 242 are both truncated cone structures, the transmission belt 2411 is at different positions on the first speed regulating member 241 and the second speed regulating member 242, and the transmission ratio of the transmission belt 2411 on the first speed regulating member 241 and the transmission belt 2411 on the second speed regulating member 242 changes. Therefore, the rotation speed of the second speed regulating member 242 can be changed by changing the position of the transmission belt 2411 on the first speed regulating member 241 and the second speed regulating member 242.

[0024] The stopper 94 in this embodiment is sleeved on the transmission belt 2411, and the first screw rod 91 and the second screw rod 92 are rotatably arranged in the speed regulating chamber 24, and the stopper 94 is threadedly connected with the first screw rod 91 and the second screw rod 92 at the same time. The synchronous belt 93 is connected with the first screw rod 91 and the second screw rod 92 at the same time, and is used to synchronize the rotation of the first screw rod 91 and the second screw rod 92. The movement of the stopper 94 is controlled by the first screw rod 91 and the second screw rod 92. Since the rotation stroke of the first screw rod 91 and the second screw rod 92 is much greater than the movement stroke of the stopper 94, the movement of the stopper 94 is more accurately and reliably controlled by the rotation of the first screw rod 91 and the second screw rod 92.

[0025] In this embodiment, the first drive motor 243 and the second drive motor 244 are fixedly arranged in the speed regulating chamber 24, the first gear 2432 is fixedly arranged on the first speed regulating member 241, the second gear 2431 is rotatably arranged in the speed regulating chamber 24, the first gear 2432 and the second gear 2431 are meshed, the output shaft of the first drive motor 243 is fixedly connected with the second gear 2431, the third gear 2442 is fixedly arranged on the first screw rod 91, the fourth gear 2441 is rotatably arranged in the speed regulating chamber 24, the third gear 2442 is meshed with the fourth gear 2441, and the output shaft of the second drive motor 244 is fixedly connected with the fourth gear 2441. Such a design is to facilitate the installation of the first drive motor 243 and the second drive motor 244, and to facilitate their control of the movement of the first speed regulating member 241 and the sliding member.

[0026] The air guide cavity 23 in this embodiment is arranged on the upper side of the speed regulating chamber 24, the air inlet pipe 21 is arranged on the side wall of the air guide cavity 23, a plurality of first air guide pipes 231 are fixedly arranged at the bottom of the air guide cavity 23, the air separation chamber 25 is arranged at the lower side of the speed regulating chamber 24, and each first air guide pipe 231 is connected to the air separation chamber 25. In this embodiment, by connecting a plurality of first air guide pipes 231 to the air separation chamber 25, the waste heat generated can be accelerated to flow to the air separation chamber 25, thereby reducing the waste heat loss during movement.

[0027] The housing 5 in this embodiment is a cylindrical structure, the air dividing chamber 251 is arranged in the air dividing chamber 25, the top of the air dividing chamber 251 is connected to the first air guide pipe 231, the limit plate 252 is rotatably arranged at the lower end of the air dividing chamber 251, and a plurality of second air guide pipes 253 are fixedly arranged at the lower end of the limit plate 252, each second air guide pipe 253 corresponds to the heating box 6 one by one, and the second air guide pipe 253 is connected to the top of the heating box 6. This embodiment adopts the design of the air dividing chamber 25, which can ensure that when the limit plate 252 rotates, the hot air in the air dividing chamber 251 can still enter the heating box 6 through the second air guide pipe 253, and can effectively reduce the heat loss caused by the leakage of hot air.

[0028] The water inlet structure in this embodiment includes a water distribution box, and the water inlet pipe 51 is arranged on the top of the shell 5. The first speed regulating member 241 is sleeved in the water inlet pipe 51 to reduce the influence of the rotation of the heating box 6 on the water inlet pipe 51. The water distribution box is arranged at the lower side of each heating box 6, and the water distribution box includes a first fixed box 71, and the water storage chamber 711 is arranged in the first fixed box 71. The first fixed box 71 is fixedly connected to the shell 5, and the second rotation groove 713 is arranged on the side wall of the first fixed box 71.

When the second rotating ring 72 rotates so that the first water outlet gap 712 is aligned with the water inlet hole 722, hot water enters the first water diversion chamber 721 of the first water outlet gap 712 and enters the heating box 6; when the second rotating ring 72 rotates so that the first water outlet gap 712 is separated from the water inlet hole 722, hot water no longer enters the first water diversion chamber 721. In this way, hot water can enter the unused heating box 6 in stages. When water does not enter the heating box 6, the water therein is heated by the residual heat, thereby extending the heating time. The area of ​​the first water outlet notch 712 used in this embodiment is larger than the area of ​​the water inlet hole 722, so as to extend the water inlet time.

[0029] The air outlet chamber 26 in this embodiment is arranged in the housing 5, and the air outlet chamber 26 includes a first rotating ring 261, which is fixedly connected to the housing 5, a first rotating groove 2611 is arranged in the first rotating ring 261, and the cross section of the first rotating groove 2611 is a "convex" structure, which is used to prevent the first rotating ring 261 from being separated from the first rotating groove 2611, and a sealing ring 262 is rotatably arranged in the first rotating groove 2611, and a gap is provided between the sealing ring 262 and the bottom of the first rotating groove 2611, and the third air guide pipe 263 is fixedly arranged between the side wall of each heating box 6 and the sealing ring 262, and the air outlet 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 ring and the lower ring are connected and fixed by bolts, so that the sealing ring 262 can be easily disassembled and installed in the first rotating ring 261. Such a design of the air outlet chamber 26 can ensure that when the sealing ring 262 rotates relative to the first rotating groove 2611 , the hot air gathered through the third air duct 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 duct 263 .

[0030] The water outlet structure in this embodiment includes a water outlet box, which is arranged at the lower end of the water distribution box. The water outlet box includes a second fixed box 81, a water collecting chamber 811 is arranged in the second fixed box 81, and a third rotating groove 813 is arranged outside the second fixed box 81. The third rotating ring 82 is rotatably arranged in the third rotating groove 813 to prevent the third rotating ring 82 from being displaced when rotating. A plurality of second water distribution chambers 821 are arranged in the third rotating ring 82, each second water distribution chamber 821 corresponds to the heating box 6 one by one, and each second water distribution chamber 821 is connected to the heating box 6 by a second water guide pipe 63, a water outlet hole 822 is arranged on the side of each second water distribution chamber 821 close to the second fixed box 81, a second water outlet notch 812 is arranged on the side of the water collecting chamber 811 close to the second water distribution chamber 821, and 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 so that the second water outlet gap 812 is aligned with the water outlet hole 822, the hot water in the heating box 6 flows from the second water outlet gap 812 to the water outlet hole 822 and flows out from the water outlet pipe 52; when the third rotating ring 82 rotates so that the second water outlet gap 812 is separated 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, thereby extending its heating time and improving the utilization rate of the remaining heat.

[0031] The hot water pipe 61 in this embodiment is arranged in the heating box 6, and the hot water pipe 61 is spirally distributed, and the first water conduit 62 and the second water conduit 63 are respectively connected to the two ends of the hot water pipe 61. The spirally distributed hot water pipe 61 allows the hot water in the hot water pipe 61 to increase the contact area with the air, so that more water can receive more heat.

[0032] Working process of this embodiment: When waste heat recovery is required, the waste heat generated by the condenser 2 passes through the air inlet pipe 21, the air guide cavity 23, the air distribution cavity 251, the heating box 6, the air outlet chamber 26, and finally flows out from the air outlet pipe 22.
