Description

Technical Field

[0001] The present invention relates to the technical field of heat pump air conditioner units, and particularly to a high-efficiency energy tower water source heat pump unit. Background Technique

[0002] A water source heat pump is a highly efficient and energy-saving device that utilizes the heat in groundwater, surface water, or other water sources for heating and cooling. It provides space heating, cooling, and hot water supply through heat exchange with water bodies, and is applicable to various occasions such as residential, commercial buildings, and industrial facilities.

[0003] However, the existing high-efficiency energy tower water source heat pump units have the following deficiencies:

[0004] The water source heat pump unit mainly consists of an evaporator, a compressor, and a condenser. Among them, the evaporator is capable of absorbing the heat in the water source and can thus be regarded as the most important component in the entire heat pump unit. However, during the actual operation of the evaporator, the external environmental conditions will have a huge impact on the work of the evaporator. If the regional temperature drops below 0°C, it will cause insufficient heat absorption by the evaporator, and a large amount of frost will appear on the fins, resulting in a sharp decline in the heat exchange efficiency. Most traditional defrosting methods rely on the reflux of high-temperature and high-pressure gaseous refrigerant discharged by the compressor to complete defrosting. This method mainly liquefies the frost through temperature, with a relatively long pre-waiting time, and the subsequent components need to stop for a long time, resulting in the unit having to be repeatedly restarted and shut down, not only causing excessive energy consumption but also low heat exchange continuity.

[0005] Therefore, we propose a high-efficiency energy tower water source heat pump unit to solve the problems raised above. Summary of the Invention

[0006] The purpose of the present invention is to provide a high-efficiency energy tower water source heat pump unit, provided with a heat conduction scraping component and a self-acting reverse pushing mechanism, which can form two independent effects at the end of the evaporator main body. One is to heat the outer part of a pair of parallel fins to accelerate the melting of the thick frost layer, and the other is to use electromagnetic adsorption to flexibly lock and release the functional components, and generate power through the cooperation of multiple components, so that the metal scraping block can reciprocate up and down to complete the scraping of the frost layer and accelerate its shedding, in order to solve the problems raised in the above background technique.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described 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.

[0032] like Figure 1 and Figures 2 - 3 As shown, this embodiment discloses a high-efficiency energy tower water source heat pump unit, including an evaporator body 2, a group of parallel fins 3 and a heat-conducting scraping component 400, wherein the group of parallel fins 3 is installed inside the evaporator body 2, and the heat-conducting scraping component 400 is installed above the evaporator body 2.

[0033] like Figure 5 and Figure 7As shown, the heat scraping component 400 includes an electromagnetic panel 404, a metal docking plate 405 and a junction box 406. The metal docking plate 405 is fixedly connected to the junction box 406. The junction box 406 is used to collect high-temperature gaseous refrigerant. The electromagnetic panel 404 is magnetically connected to the metal docking plate 405. The electromagnetic panel 404 can freely control the generation and disappearance of magnetic force, so that the junction box 406 has a hanging condition. The side of the junction box 406 is combined with a packaged thermal conductive plate 407. The packaged thermal conductive plate 407 is used for further heat transfer. The outer wall of the packaged thermal conductive plate 407 is connected to multiple groups of metal scrapers 408, and each group of metal scrapers 408 is fully in contact with a corresponding parallel fin 3. The heat that penetrates into the packaged thermal conductive plate 407 is further transferred by each group of metal scrapers 408, and finally acts on the parallel fin 3.

[0034] In more specific solutions, such as Figure 5 As shown, the heat-conducting scraping assembly 400 also includes a load-bearing external frame 401, which is installed on the top of the evaporator body 2. The lower part of the load-bearing external frame 401 is bolted with an adapter bottom bracket 402, and the wiring hub 403 is fixedly connected to the adapter bottom bracket 402. The adapter bottom bracket 402 and its connected components are located at the end of the evaporator body 2 in a suspended manner.

[0035] Among the more preferred solutions, Figure 5 As shown, the reverse side of the load-bearing external frame 401 is bolted with two extended arms 409, and a transition joint 410 is inserted at the end of each extended arm 409. An air inlet joint and an air exhaust joint are respectively arranged above the two transition joints 410. The bottom of each transition joint 410 is connected to a hard straight joint 411, and the bottom of each hard straight joint 411 is connected to a folding hose 412. The end of each folding hose 412 is connected to a hard bent joint 413. The two hard bent joints 413 are connected to the junction box. 406 is connected to the outer wall and communicated with the interior of the junction box 406. A non-contact temperature sensor 414 is installed above the load-bearing external frame 401. The non-contact temperature sensor 414 is used to monitor the external temperature in real time. The non-contact temperature sensor 414 is electrically connected to the wiring hub 403. Two grooves are opened above the wiring hub 403, and the two grooves are respectively provided with an electric control module 415 and a receiving module 416. The electric control module 415 and the receiving module 416 are electrically connected. The electric control module 415 is electrically connected to the wiring hub 403.

[0036] To collect part of the high-temperature gaseous refrigerant, the external conveying pipeline is connected to the intake joint on a transition joint 410. The temperature data real-time feedback by the non-contact temperature sensor 414 during operation in the evaporator body 2 is shared with the unit system, enabling more accurate control of defrosting. After the process starts, the unit electromagnetic expansion valve opens, and the high-temperature gaseous refrigerant continuously flows back into the evaporator body 2. And part of the gaseous refrigerant flows into the junction box 406 through the passage constructed by a transition joint 410. Through temperature penetration, it is continuously transferred by the encapsulated heat conduction plate 407 and acts on the connected metal scraping block 408 to complete the liquefaction of the frost on the outside of the parallel fins 3. The heating time is Figure 5 controlled by the electronic control module 415 in Figure 5 . The specific duration is set manually. When the time arrives, the electronic control module 415 timely disconnects the power supply of the electromagnetic panel 404. The surface of the electromagnetic panel 404 loses magnetism, and the metal docking plate 405 and its components lose restraint and start to droop downward under the action of gravity. Since the folding hose 412 has a folding and stretching effect, it will not restrict the movement of the components.

[0037] As Figure 2 and Figures 7 - 8 shown, a self-powered anti-push mechanism 500 is provided above the expansion base 1. The self-powered anti-push mechanism 500 includes two outer shell sleeves 501 and two groups of path tracks 502. Each group of path tracks 502 is respectively arranged in a corresponding outer shell sleeve 501. A roller member 503 is installed inside each group of path tracks 502. A cross support plate 504 is combined between the two roller members 503. The cross support plate 504 is fixedly connected to the junction box 406. By connecting the two, when the junction box 406 drops, the cross support plate 504 follows synchronously. During the process, the roller member 503 rolls inside the path track 502, and the path track 502 limits the roller member 503 itself to ensure that the junction box 406 does not shift in position when it drops.

[0038] In a more specific solution, a rubber folding seat 505 is installed below the cross support plate 504. The rubber folding seat 505 can be compressed by pressure to generate reverse kinetic potential energy. A rectangular shell sleeve 506 is installed inside the expansion base 1. A plurality of limit seats 507 are inserted into the rectangular shell sleeve 506. A metal sliding rod 508 is movably inserted into each limit seat 507. The tops of the plurality of metal sliding rods 508 are combined into a push-back plate 509. The size of the push-back plate 509 is adapted to the rectangular shell sleeve 506.

[0039] When the rubber folding seat 505 contacts the push-back plate 509, both will generate external forces in opposite directions to each other. The former folds and compresses using its own material and structural characteristics. The latter, because the limit seat 507 and the metal sliding rod 508 are movably inserted, enables the push-back plate 509 to move downward a certain distance and briefly lose support for the rubber folding seat 505, and will quickly return to its initial state and exert an upward thrust on the junction box 406.

[0040] In a more preferred solution, an active spring 510 is connected between each limiting seat 507 and the reverse pushing plate 509. Each active spring 510 is movably connected to a corresponding metal sliding rod 508. A anti-disengagement buckle 511 is connected below each metal sliding rod 508. The diameter of the anti-disengagement buckle 511 is larger than that of the limiting seat 507, and is used to limit the pulling length of the metal sliding rod 508.

[0041]

[0040] When the reverse pushing plate 509 retracts into the rectangular housing sleeve 506, the active springs 510 between the limiting seat 507 and the reverse pushing plate 509 are all in a compressed state. When the junction box 406 rises a certain distance under the reverse thrust applied by the rubber folding seat 505, the active springs 510 that lose the pressure coverage will also quickly complete the pushing away of the reverse pushing plate 509 under the reaction force generated by the active springs 510, and will catch up with the rising trend of the junction box 406 in a short time, and further apply a second-stage thrust to the junction box 406 to increase the driving force of the junction box 406. During the process, the metal scraping block 408 continuously scrapes the outer wall of the parallel fins 3. When the upward kinetic potential energy disappears, the junction box 406 and its connected components will fall again and repeat the action repeatedly to achieve the purpose of accelerating defrosting.

[0042] When the junction box 406 rises, the electromagnetic panel 404 is in an energized state. When the position of the metal docking plate 405 reaches the adsorption range of the electromagnetic panel 404, it will be attracted to lock the junction box 406 again. After completion, the power is quickly cut off, so that the falling power of the junction box 406 is always in a relatively high state, avoiding the continuous weakening of the subsequent rebound power and causing the junction box 406 to be unable to reset.
