Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to an omnidirectional air conditioning device and a heat exchange and air supply system powered by solar energy. Background Technology

[0002] The indoor units of existing air conditioning systems are typically installed in the corners of rooms because most living spaces are rectangular. When the air conditioning system is working, the airflow from the indoor unit circulates along the length or width of the rectangular space, exchanging heat with heat sources within the space. However, for cylindrical or centrally symmetrical living spaces, airflow from a single corner cannot quickly and effectively create an airflow circulation throughout the main internal volume. Some corners may even remain independent of the main circulation, resulting in poor heat exchange participation and thus affecting temperature regulation quality and user comfort.

[0003] Some symmetrical living spaces, such as yurts, dome tents, and octagonal pavilions, also require cooling or heating to regulate air quality. Some of these structures are located far from urban power grids, while others are temporary buildings, making grid connection inconvenient, yet they still have a need to utilize clean solar energy. Existing outdoor air conditioning systems operating on solar power are not very effective, which is related to the photoelectric conversion rate of photovoltaic panels. A significant factor affecting this conversion rate is dust accumulation on the panels, necessitating long-term, automated dust removal measures.

[0004] Therefore, existing technologies still need to be improved and developed. Summary of the Invention

[0049] This invention provides an omnidirectional air conditioning device and a solar-powered heat exchange and air supply system. To make the objectives, technical solutions, and effects of this invention clearer and more explicit, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention.

[0050] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0051] This application uses an outdoor octagonal roof building located far from urban areas as an example for illustration. For instance... Figure 1 As shown, the center of the outer roof of the building 3 is a flat circular surface. Around this central circular surface, two rings of fan-shaped photovoltaic panels are laid, including an inner ring of photovoltaic panels 1 and an outer ring of photovoltaic panels 2. The inner ring of photovoltaic panels 1 and the outer ring of photovoltaic panels 2 cover all the outer roof outside the central circular surface.

[0052] The omnidirectional air conditioning device in this embodiment includes an outdoor unit and an indoor unit. The aforementioned flat circular surface is the installation area for installing the outdoor unit and the indoor unit. Specifically, the outdoor unit is installed at the upper end of the installation area, outside the building 3, and the indoor unit is installed at the lower end of the installation area, inside the building 3. A power collection module is also provided, which includes an energy storage box 5 placed inside the building 3 and electrically connected to the photovoltaic panel, and a controller 4 placed inside the building 3 and electrically connected to the energy storage box 5. The output terminal of the controller 4 is electrically connected to the outdoor unit and the indoor unit through wires.

[0053] Because the photovoltaic panels on the roof of building 3 are arranged radially, covering the exterior of building 3 and receiving sunlight from all directions, the electrical energy generated by the inner photovoltaic panels 1 and the outer photovoltaic panels 2 is collected by wires and transmitted to the input terminal of controller 4. Controller 4 can be installed above energy storage box 5, which is located on the inside of one of the walls of building 3, resting on the ground. Controller 4 can modulate the fluctuating power supply during the day into a more stable form over time, and adjust the load power supply and energy storage ratio according to the load demand. Correspondingly, the output terminal of controller 4 branches off wires to connect the compressor 14 and the third motor 16 of the outdoor unit of this application, the first motor 27 and the second motor 30 of the indoor unit, and the wiring terminal of energy storage box 5. Energy storage box 5 contains a rechargeable battery pack that can store a large capacity of electrical energy. In the absence of sunlight, energy storage box 5 supplies power in reverse, supplying electrical energy to the load demanding through controller 4, supporting the operation of the omnidirectional air conditioning device of this application for a period of time.

[0054] like Figure 2 As shown, the outdoor unit of this embodiment includes a cage-shaped bracket, a shroud 7 fixed to the cage-shaped bracket, a first heat exchange module located above the shroud 7, and a first fan module located below the shroud 7 that causes the gas in the first heat exchange module to flow downwards. The first fan module can be a volute-less fan. Specifically, the first fan module includes a third motor 16 fixed to the first layer frame 18 and a fan wheel 15 connected to the output end of the third motor 16, with the fan wheel 15 facing upwards. After the third motor 16 starts, it drives the fan wheel 15 to rotate. When the fan wheel 15 rotates, it draws air in from the center and discharges air from the outer ring. During the air intake process of the fan wheel 15, the airflow in the heat exchange area of ​​the first heat exchange module moves from the outside to the inside and then downwards, thereby blowing on the vertical fins 49 and the first through-tube 53 of the first heat exchange module, generating forced convection heat exchange, and then the heat of the refrigerant in the first through-tube 53 is transferred to the outside air.

[0055] Please refer to Figure 2 and Figure 3In this embodiment, the shroud 7 is generally umbrella-shaped. The top of the shroud 7 has an opening, forming the first through-hole. The diameter of the first through-hole is between the outer diameter of the impeller 15 and the inner diameter of the radial finned tube heat exchanger 13. The suction airflow enters the impeller 15 through the first through-hole. Under the suction action of the impeller 15, the gas in the first heat exchange module passes downwards through the first through-hole and is blown outwards along the lower end of the shroud 7. The downward-curved arc surface of the shroud 7 guides the airflow from the outer ring of the first fan module downwards at a suitable angle, causing the exhaust airflow to rush towards the surface of the photovoltaic panel. This blows away dust particles and debris adhering to the photovoltaic panel surface, keeping the panel relatively clean and preventing the energy conversion rate from decreasing due to obstruction by these contaminants.

[0056] The inner surface of the flow guide 7 does not contact the impeller 15. The flow guide 7 is flanged at the position through which the ring column 8 passes, and is connected to the ring column 8 through the flange to make the structure more robust.

[0057] In addition, the vertical projection range of the cage-shaped support falls within the vertical projection range of the diversion hood 7; by increasing the size of the diversion hood 7, it is possible to prevent foreign objects such as rain, snow, and hail from entering the first fan module and other components below the first fan module.

[0058] Furthermore, the portion of the hood 7 that covers the inner ring photovoltaic panel 1 at the top of the building 3 is made of a highly transparent material to prevent it from blocking light and affecting the light-receiving and power-generating effect of the inner ring photovoltaic panel 1.

[0059] like Figure 3 As shown, the top of the drainage hood 7 is in close contact with the middle annular seat of the second layer frame 12 to prevent airflow and improve sealing.

[0060] The outdoor unit of this application is responsible for transferring the heat transferred by the refrigerant to the external space and absorbing solar energy to convert it into electricity. An omnidirectional air conditioning unit is constructed at the center of the building's roof using a multi-layered cage-like support structure. Please refer to... Figure 5 The cage-shaped support includes a mounting base 11, an outer ring column 8 fixed to the upper end of the mounting base 11, a top sealing plate 21 fixed to the upper end of the outer ring column 8, and a first ring frame 18, a second ring frame 12, and a third ring frame 20 fixed to the inner side of the outer ring column 8 from bottom to top; the lower end of the third ring frame 20 is connected to a disc mounting seat 23 through an inner ring column 22; a drainage hood 7 is set on the upper end of the second ring frame 12; system components such as the compressor 14 and the liquid storage tank 19 are mounted on the disc mounting seat 23.

[0061] like Figure 5As shown, the first-layer ring frame 18 is connected to the outer ring column 8 by square tube profile 24; the cage-shaped support has two rings of columns from the inside to the outside, namely the inner ring column 22 and the outer ring column 8. The lower end of the outer ring column 8 is the mounting base 11, and the bottom of the mounting base 11 is bolted to the center plane of the outer roof of the building 3. The connection position has anti-vibration structures such as rubber pads; the annular surface of the first-layer ring frame 18 is bolted to the mounting seat of the third motor 16.

[0062] Furthermore, the first heat exchange module includes a radial finned tube heat exchanger 13 arranged around the inner ring column of the cage-shaped support, a compressor 14 fixed to the cage-shaped support and located inside the radial finned tube heat exchanger 13, a liquid storage tank 19, and an expansion valve, etc. The radial finned tube heat exchanger 13 includes a first upper end plate 47, a first lower end plate 50, a first tie rod 48 connected between the first upper end plate 47 and the first lower end plate 50, and a number of spaced vertical fins 49, a first through pipe 53 that passes through the vertical fins 49 in a row along the circumference and has a back-and-forth bending structure, and a vertical manifold 52 connected to the liquid outlet of the first through pipe 53, the vertical manifold 52 being connected to the pipe assembly.

[0063] The radial finned tube heat exchanger 13 is maintained by a first tie rod 48 between the upper and lower end plates. The compressor 14 can be a vertical scroll compressor. In refrigeration mode, the compressor 14 operates, and the refrigerant in its connected pipes circulates and its state changes. The refrigerant condenses and releases heat within the radial finned tube heat exchanger 13. This released heat is first transferred to the tube wall of the first through-tube 53 and the vertical fins 49, and then dissipated to the outside through convection heat transfer generated by the airflow from the center of the impeller 15.

[0064] A piping assembly connects the first and second heat exchange modules, transferring refrigerant from the first heat exchange module of the outdoor unit to the second heat exchange module of the indoor unit. The refrigerant in the tube bundle of the annular finned tube heat exchanger 32 of the indoor unit evaporates and absorbs heat, transferring the cooling energy to the airflow on the surface of the annular fins 43 and the second through-tube 45. As the first impeller 28 and the second impeller 29 rotate, the cooled airflow is dispersed in all directions, encountering the indoor wall and reversing to form a circulating flow, continuously circulating heat and mass. The circulation path is described in [reference needed]. Figure 2 Lower the overall indoor temperature.

[0065] The refrigerant outflow main pipe 33 connecting the indoor and outdoor units of the omnidirectional air conditioning unit has a sealing measure at the perforation at the top of the building 3. The outflow main pipe 33, which transports refrigerant at a lower temperature, is wrapped with an insulated sleeve. The refrigerant outflow main pipe 33 and inflow main pipe 34, which pass through the outer roof of the building, bypass the third motor 16, continue upward along the outer ring column 8 of one of the cage-shaped supports, and then pass through the guide shroud 7. From the position of the second ring frame 12 or the first ring frame 18, they turn horizontally, along one of the square tube profiles 24, pass through the first protective net 9, and enter the radial finned tube heat exchanger 13 above the first upper end plate 47 or below the first lower end plate 50, bypassing the plate surface to enter the second ring frame 12. The refrigerant outflow main pipe 33 and inflow main pipe 34 distribute or centralize the flow rates of each branch of the annular finned tube heat exchanger 32, and connect with system components such as the radial finned tube heat exchanger 13, liquid receiver 19, expansion valve, and compressor 14 to form a loop, so that the refrigerant can circulate. The connection of the above pipeline components is similar to that of conventional air conditioning equipment, so it is not shown in the view of this example.

[0066] The feet of compressor 14, the feet of liquid receiver 19, and some pipeline fasteners are all bolted to the disc mounting base 23. The second-layer frame 12 is also provided with some short columns to provide auxiliary support for the radial finned tube heat exchanger 13 and to provide auxiliary hanging positions for the pipeline fasteners. A cylindrical first protective mesh 9 is provided around the radial finned tube heat exchanger 13 to prevent dust particles and other foreign objects from being sucked into the gaps between the vertical fins 49. The upper and lower edges of the first protective mesh 9 contact and connect with the third-layer frame 20 and the second-layer frame 12, respectively, by means of flanged openings and screw connections.

[0067] like Figure 4 As shown, the top of the cage-shaped support is equipped with a rain cover 10; as Figure 6 As shown, a sealing connector 51 is also provided at the lower end of the first lower end plate 50 to provide good sealing protection for the bottom of the first lower end plate 50.

[0068] Please refer to Figure 7 and Figure 8 The indoor unit includes a mounting bracket, a second heat exchange module fixed inside the mounting bracket, a first fan wheel 28 and a second fan wheel 29 arranged sequentially on the outside of the mounting bracket in the vertical direction, a first motor 27 for driving the first fan wheel 28, and a second motor 30 for driving the second fan wheel 29. The rotation directions of the first fan wheel 28 and the second fan wheel 29 are opposite.

[0069] Please refer to Figure 7 and Figure 8The lifting support includes a flange 25, a first mounting plate 26 fixed to the lower end of the flange 25, a plurality of annularly distributed ring-shaped column members 35 connected to the lower end of the first mounting plate 26, and a second mounting plate 31 connected to the lower end of the ring-shaped column members 35. The ring-shaped column members 35 are evenly distributed in a circle. The upper end of the ring-shaped column members 35 is fixedly connected to the pipe wall below the top flange 25 of the lifting support. A certain distance downward from the upper end, the body of the ring-shaped column members 35 is welded and fixedly connected to the inner ring wall of the first mounting plate 26. The lower end of the ring-shaped column members 35 is welded and fixedly connected to the inner ring wall of the second mounting plate 31.

[0070] The indoor unit of this application is installed by ceiling mounting inside building 3, without the need to modify the roof space. The flange 25 at the top of the indoor unit's mounting bracket can be connected to the middle of the ceiling using ceiling expansion bolts, or the flange 25 at the top of the mounting bracket can be held in place by a hanger hanging from the top beam, with a vibration damping structure applied at the connection point.

[0071] like Figure 7 As shown, the indoor unit's mounting bracket has a first mounting plate 26 and a second mounting plate 31. The first mounting plate 26 is used to mount the first motor 27; the second mounting plate 31 is used to mount the second motor 30. The stator plates of the first motor 27 and the second motor 30 are bolted to the first mounting plate 26 and the second mounting plate 31, which are welded to the inner annular column member 35 of the mounting bracket, respectively. Both the first motor 27 and the second motor 30 are disc-type permanent magnet hollow brushless motors. The blades of the first fan wheel 28 and the second fan wheel 29 are directly driven by the outer rotor housing of the disc-type permanent magnet hollow brushless motor, discharging airflow outward 360°. This, in turn, drives the airflow on the annular finned tube heat exchanger 32 inside the first fan wheel 28 and the second fan wheel 29, between the annular finned tube heat exchanger 32 and the second through-tube 45, generating convective heat transfer and indirectly exchanging heat with the refrigerant inside the tube.

[0072] The second lower end plate 42 of the annular finned tube heat exchanger 32 is also bolted to the connecting piece fixed on the annular column member 35 by the diagonal tie plate 36 to improve the hanging strength. See Figure 8 .

[0073] like Figure 9 As shown, the annular fin 43 is provided with a second upper end plate 44 and a second lower end plate 42 with a slightly larger outer diameter. The upper and lower ends of the second tie rod 41 are bolted to the second upper end plate 44 and the second lower end plate 42 respectively to maintain the shape of the annular finned tube heat exchanger 32.

[0074] The toroidal fin 43 has specially designed ribbed protrusions 54, which guide airflow and enhance the turbulence of the surface-attached airflow. (See...) Figure 10 .

[0075] The second heat exchange module includes an annular finned tube heat exchanger 32, located inside the annular area formed by the annular column member 35. A first fan wheel 28 and a second fan wheel 29 are fitted onto the outside of the annular column member 35; the first fan wheel 28 faces downwards, and the second fan wheel 29 faces upwards, with the annular discs fixed between the first fan wheel 28 and the second fan wheel 29 separated by a gap. When simultaneously dispersing air outwards, the first fan wheel 28 and the second fan wheel 29 rotate in opposite directions, canceling out the counter-torque on the suspension bracket and improving the dynamic stability of the entire suspension structure.

[0076] A cylindrical second protective net 6 is installed around the first fan wheel 28 and the second fan wheel 29 to prevent accidents caused by the first fan wheel 28 or the second fan wheel 29 hitting people or foreign objects during rotation. The dense mesh on the second protective net 6 disperses the airflow. The tangential velocities of the first fan wheel 28 and the second fan wheel 29 are opposite, causing the airflow to diffuse radially. After a certain outflow distance, the airflow mixes with each other, and the vortex formation becomes more complex, which helps to homogenize the temperature.

[0077] When the first fan wheel 28 and the second fan wheel 29 rotate, the propelled air flows radially from the center outwards, exhibiting both tangential and radial velocities, with consistent airflow in every direction along the circumference. The airflow within the first fan wheel 28 and the second fan wheel 29, and within the toroidal fins 43, also moves accordingly, engaging in convective heat exchange with the metal surface. Subsequently, the heat from the refrigerant within the metal tube bundle is transferred to the heat of the indoor air, effectively regulating the airflow. The airflow generated by the first fan wheel 28 and the second fan wheel 29 continues to diffuse, reaching the indoor side walls and reversing to form a circulating flow. Air is then drawn in from the center of the first fan wheel 28 and the second fan wheel 29, completing the cycle. (Path reference...) Figure 2 The blowing distance from the first impeller 28 and the second impeller 29 to each side wall is the same, and the resulting recirculating flow, viewed from the cross-section of the room, is basically centrally symmetrically distributed. The recirculating flow in all directions surrounds the indoor space, and the overall distribution is relatively uniform, providing a fairly even wind experience and comfort for the people inside.

[0078] Lights can be added around the second protective net 6 to make this application function as a chandelier; patterns can also be added to serve as interior decoration.

[0079] The wiring harnesses of the first motor 27 and the second motor 30 are inserted into the inner side of the ring column member 35, emerge from the top of the hoisting bracket, are secured against the inner top of the hoisting bracket, and finally connected to the output terminal of the controller 4.

[0080] The annular finned tube heat exchanger 32 includes several annular fins 43 stacked vertically in sequence, second through-tubes 45 equidistantly distributed around the annular fins 43 and folded back and forth, liquid distributors 38 connected to the liquid inlets of all the second through-tubes 45, and a collection ring pipe 46 connected to the liquid outlets of all the second through-tubes 45.

[0081] The hoisting support also includes a circle 37 that connects all the annular column members 35 in a ring shape, and the inner side of the circle 37 is also connected to the annular finned tube heat exchanger 32; the annular column members 35 are also provided with a number of diagonal tie plates 36 for strengthening structural stability. The piping assembly includes an outflow main pipe 33 and an inflow main pipe 34 that form a heat exchange loop with the first heat exchange module; the lower end of the inflow main pipe 34 is connected to the liquid separator 38; the lower end of the outflow main pipe 33 is connected to the manifold ring pipe 46.

[0082] The second through-tubes 45 of each branch of the annular finned tube heat exchanger 32 are also symmetrically distributed about the center, with each branch having 4-5 reversal strokes to control the flow resistance within a suitable range. The spacing between the second through-tubes 45 is approximately four times the outer diameter of the tube. Each first through-tube 53 has an inlet and outlet at the top, and its path through the annular fins 43 is a Z-shaped zigzag. Figure 9 and Figure 10 As shown, the inlet pipe of the second through pipe 45 is connected to the flow equalization capillary hanging down from the liquid distribution head 38 at the lower end of the inlet main pipe 34. The outlet pipe of the second through pipe 45 is connected to the flow collecting ring pipe 46, which is then connected to the upward-facing outlet main pipe 33.
