Description

Technical Field

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

[0002] The indoor unit of existing air conditioners is usually installed in the corner of the room, because the general living space is a rectangular structure. When the air conditioner is working, the airflow blown out by the indoor unit will circulate in the length or width direction of the rectangular space to exchange heat with the heat source in the rectangular living space. However, for cylindrical or centrally symmetrical living spaces, the air supply from a single direction of a corner cannot quickly and effectively form an airflow loop throughout the main internal volume. Some corners are even always independent of the main circulation, and the heat exchange participation is poor, which affects the temperature regulation quality and body comfort.

[0003] Some human settlements with central symmetry, such as yurts, dome tents, octagonal pavilions, etc., also need to cool down or heat up to adjust the air condition. Some structures with such human settlements are far away from the urban power grid, and some are temporary buildings, which are not convenient for connecting to the power grid, but there is a need to use clean light energy. The existing air conditioning equipment is not very effective in outdoor environments using electricity generated by light energy resources. This is related to the light-to-electricity conversion rate of photovoltaic panels. An important factor affecting the conversion rate is the dust accumulation on the panel, which requires long-term automatic dust removal measures.

DETAILED DESCRIPTION

[0049] The present invention provides an omnidirectional air supply air conditioning device and a heat exchange air supply system powered by solar energy. In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0050] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0051] This application is described using an outdoor octagonal building far from an urban area as an example. Figure 1 As shown, the center of the outer top of the building 3 is a flat circular surface, and two circles of fan-shaped photovoltaic panels are laid around the central circular surface, including an inner circle photovoltaic panel 1 and an outer circle photovoltaic panel 2. The inner circle photovoltaic panel 1 and the outer circle photovoltaic panel 2 cover all the outer tops outside the central circular surface.

[0052] The omnidirectional air-supply air-conditioning device of the present embodiment includes an outdoor unit and an indoor unit. The above-mentioned flat circular surface position is used as 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. The power collection module includes an energy storage box 5 placed in the building 3 and electrically connected to the photovoltaic panel, and a controller 4 placed in the building 3 and electrically connected to the energy storage box 5. The output end of the controller 4 is electrically connected to the outdoor unit and the indoor unit through a wire.

[0053] Since the photovoltaic panels on the top of the building 3 are laid radially, covering the outer top of the building 3 and receiving sunlight from all directions, the electric energy generated by the inner circle photovoltaic panel 1 and the outer circle photovoltaic panel 2 is collected through wires and transmitted to the input end of the controller 4. The controller 4 can be installed above the energy storage box 5, and the energy storage box 5 is located on the inner side of one of the walls of the building 3 and falls on the ground. The controller 4 can modulate the transmission power that fluctuates during the day into a relatively flat form over time, and allocate the load power supply and storage ratio according to the load of the energy demand end. Correspondingly, the output end of the controller 4 branches out wires to connect the compressor 14, the third motor 16 of the outdoor unit of the present application, the first motor 27, the second motor 30 of the indoor unit, and the connection terminal of the energy storage box 5. The energy storage box 5 contains a rechargeable battery pack that can store a large capacity of electric energy. In the absence of sunlight, the energy storage box 5 reverses power, supplies power to the energy demand load through the controller 4, and supports the omnidirectional air supply air conditioning device of the present application to work for a period of time.

[0054] like Figure 2 As shown, the outdoor unit of this embodiment includes a cage-shaped bracket, a drainage cover 7 fixed to the cage-shaped bracket, a first heat exchange module located above the drainage cover 7, and a first fan module located below the drainage cover 7 and allowing the gas of the first heat exchange module to flow downward; the first fan module can be a volute-free fan, and the first fan module specifically includes a third motor 16 fixed to the first layer of the ring frame 18, and a wind wheel 15 connected to the output end of the third motor 16, and the wind wheel 15 is arranged upward; after the third motor 16 is started, the wind wheel 15 is driven to rotate, and the wind wheel 15 rotates to suck air in the center and discharge air in the outer circle. The wind wheel 15 sucks air and drives the air flow in the heat exchange area of ​​the first heat exchange module above to move from the outside to the inside and then downward, thereby blowing the vertical fins 49 and the first through pipe 53 of the first heat exchange module, generating forced convection heat exchange, and then the heat of the refrigerant in the first through pipe 53 is transferred to the external air.

[0055] Please refer to Figure 2 and Figure 3The drainage cover 7 of this embodiment is generally in an umbrella-conical structure. The top of the drainage cover 7 is opened to form a first through hole. The aperture of the first through hole is between the outer diameter of the wind wheel 15 and the inner diameter of the radial fin tube heat exchanger 13. The suction airflow enters the wind wheel 15 through the first through hole. Under the suction action of the wind wheel 15, the gas in the first heat exchange module passes downward through the first through hole and then blows out along the lower end of the drainage cover 7. The curved surface of the drainage cover 7 guides the air outlet of the outer circle of the first fan module to deflect downward at a suitable angle, so that the exhaust airflow rushes to the surface of the photovoltaic panel, which can blow away the dust particles and debris attached to the surface of the photovoltaic panel, so that the surface is kept in a relatively clean state, so that the energy conversion rate is not attenuated due to the obstruction of these dirt.

[0056] The inner surface of the guide cover 7 has no contact with the wind wheel 15, and the guide cover 7 is flanged at the position where the circle column 8 passes through, and is connected to the circle column 8 through the flange, so that the structure is more solid.

[0057] In addition, the vertical projection range of the cage-shaped bracket falls within the vertical projection range of the drainage cover 7; by increasing the size of the drainage cover 7, foreign objects such as rain, snow, and hail can be prevented from entering the first fan module and other components below the first fan module.

[0058] Furthermore, the portion of the drainage cover 7 that covers the inner circle photovoltaic panels 1 on the top of the building 3 is made of highly transparent material to prevent the shading from affecting the light-receiving and power generation effect of the inner circle photovoltaic panels 1.

[0059] like Figure 3 As shown, the top of the drainage cover 7 is in close contact with the middle circular ring seat of the second layer of the ring frame 12 to prevent air flow from passing through and improve the sealing performance.

[0060] The outdoor unit of the present application is responsible for transferring the heat transferred by the refrigerant to the external space and absorbing solar energy to convert it into electrical energy. An omnidirectional air supply air conditioning device is built at the center of the outer top of the building 3 based on a multi-layer cage-shaped bracket. Please refer to Figure 5 The cage-shaped bracket 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, a first-layer frame 18, a second-layer frame 12, and a third-layer frame 20 fixed to the inner side of the outer ring column 8 from bottom to top; the lower end of the third-layer frame 20 is connected to a disc mounting seat 23 through an inner ring column 22; the drainage cover 7 is arranged on the upper end of the second-layer frame 12; the compressor 14, the liquid storage tank 19 and other system components are installed on the disc mounting seat 23.

[0061] like Figure 5As shown, the first layer of the ring frame 18 is connected to the outer ring column 8 through a square tube profile 24; the cage-shaped bracket has two circles of columns from the inside to the outside, namely the inner circle column 22 and the outer circle column 8. The lower end of the outer circle column 8 is a mounting base 11, and the lower side of the mounting base 11 is bolted to the central plane of the outer top of the building 3, and the connection position has a vibration-proof structure such as a rubber pad; the annular surface of the first layer of the ring frame 18 is bolted to the mounting base of the third motor 16.

[0062] Furthermore, the first heat exchange module includes a radial fin tube heat exchanger 13 arranged around the inner circle columns of the cage bracket, a compressor 14 fixed to the cage bracket and located on the inner side of the radial fin tube heat exchanger 13, a liquid storage tank 19, an expansion valve and other system components; the radial fin tube heat exchanger 13 includes a first upper end plate 47, a first lower end plate 50, a first pull rod 48 connected between the first upper end plate 47 and the first lower end plate 50 and a plurality of spaced vertical fins 49, a first through-tube 53 that passes through the vertical fins 49 in a row along the circumferential direction and has a back-and-forth bending structure, and a vertical header 52 connected to the liquid outlet of the first through-tube 53, and the vertical header 52 is connected to the pipeline assembly.

[0063] The radial fin tube heat exchanger 13 is maintained in its structure by a first tie rod 48 between the upper and lower end plates. The compressor 14 can be a vertical scroll compressor. In the refrigeration working mode, the compressor 14 is running, and the refrigerant in the connected pipeline circulates and changes its state. The refrigerant in the radial fin tube heat exchanger 13 condenses and releases heat. The 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 the convection heat transfer of the airflow movement generated by the central suction of the wind wheel 15.

[0064] A pipe assembly is connected between the first heat exchange module and the second heat exchange module, through which the refrigerant of the first heat exchange module of the outdoor unit is transferred 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 cold to the airflow on the surface of the annular fin 43 and the second through-tube 45. As the first impeller 28 and the second impeller 29 rotate, the cooled airflow is dispersed to the surroundings, and when it encounters the indoor wall, it returns to form a circling flow, and the heat and mass circulation is continuously carried out. The circulation path is shown in FIG. Figure 2 . Lower the temperature of the entire room.

[0065] The refrigerant outflow pipe 33 connecting the indoor unit and the outdoor unit of the omnidirectional air supply air conditioner has sealing measures at the perforation on the top of the building 3, and the outflow pipe 33 for conveying the refrigerant with a lower temperature is wrapped with a heat preservation sleeve. The refrigerant outflow pipe 33 and the inflow pipe 34 passing through the outer top of the building bypass the third motor 16, continue to go up along the outer ring column 8 of the outer layer of one of the cage-shaped brackets, and then pass through the drainage cover 7, turn horizontally from the second layer of the frame 12 or from the position of the first layer of the frame 18, and pass through one of the square tube profiles 24, through the first protective net 9, and enter the first upper end plate 47 or the lower end plate 50 of the radial fin tube heat exchanger 13 through the nearest perforation, bypass the plate surface and enter the second layer of the frame 12. The refrigerant outflow main pipe 33 and inflow main pipe 34 distribute or aggregate the flow of each branch of the annular fin tube heat exchanger 32, and are connected with the radial fin tube heat exchanger 13, the liquid storage tank 19, the expansion valve, the compressor 14 and other system components to form a loop to circulate the refrigerant. 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 foot of the compressor 14, the foot of the liquid storage tank 19 and some pipeline fasteners are fixed on the disc mounting seat 23 with bolts. The second layer of the ring frame 12 is also provided with some short columns to provide auxiliary support for the radial fin tube heat exchanger 13 and provide auxiliary hanging positions for the pipeline fasteners. A circle of cylindrical first protective net 9 is set around the radial fin tube heat exchanger 13 to prevent dust particles and other foreign matter from being sucked into the gap between the vertical fins 49. The upper and lower edges of the first protective net 9 are respectively in contact with and connected to the third layer of the ring frame 20 and the second layer of the ring frame 12, and the connection method is flanged opening and screw connection.

[0067] like Figure 4 As shown, a top cover 10 for keeping out rain is provided on the top of the cage-shaped bracket; 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 hanging bracket, a second heat exchange module fixed on the inner side of the hanging bracket, a first impeller 28 and a second impeller 29 arranged on the outer side of the hanging bracket in the up and down directions, a first motor 27 for driving the first impeller 28, and a second motor 30 for driving the second impeller 29. The first impeller 28 and the second impeller 29 have opposite rotation directions.

[0069] Please refer to Figure 7 and Figure 8The hanging bracket includes a flange 25, a first mounting plate 26 fixed to the lower end of the flange 25, a plurality of annularly distributed ring column rods 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 column rods 35. The ring column rods 35 are evenly distributed in a circle, the upper end of the ring column rods 35 is fixedly connected to the pipe wall under the top flange 25 of the hanging bracket, and the rod body of the ring column rod 35 is fixedly connected to the inner ring wall of the first mounting plate 26 by welding at a distance below the upper end, and the lower end of the ring column rod 35 is fixedly connected to the inner ring wall of the second mounting plate 31 by welding.

[0070] The indoor unit of the present application is suspended and installed on the ceiling of the building 3, and there is no need to modify the roof space. The flange 25 on the top of the indoor unit's hanging bracket can be connected to the middle of the ceiling with ceiling expansion bolts, or the flange 25 on the top of the hanging bracket can be pulled by a hanger hanging from the top beam, and an anti-vibration structure is applied to the connection.

[0071] like Figure 7 As shown, the hanging bracket of the indoor unit has a first mounting plate 26 and a second mounting plate 31, the first mounting plate 26 is used to install the first motor 27; the second mounting plate 31 is used to install the second motor 30; the stator plates of the first motor 27 and the second motor 30 are respectively bolted to the first mounting plate 26 and the second mounting plate 31 welded on the inner ring column rod 35 of the hanging bracket. The first motor 27 and the second motor 30 both adopt disk-type permanent magnet hollow brushless motors, and the blades of the first impeller 28 and the second impeller 29 are directly driven by the outer rotor shell of the disk-type permanent magnet hollow brushless motor, and the airflow is discharged outward 360°, which then drives the airflow movement between the annular fins 43 of the annular fin tube heat exchanger 32 on the inner side of the first impeller 28 and the second impeller 29 and the second through pipe 45, generating convection heat exchange, and indirectly exchanging heat with the refrigerant in the tube.

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

[0073] like Fig. 9 As shown, the annular fin 43 is provided with a second upper end plate 44 and a second lower end plate 42 with slightly larger outer diameters, and 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 fin tube heat exchanger 32.

[0074] The annular fin 43 has specially designed rib protrusions 54, which guide the airflow and enhance the turbulence of the airflow attached to the surface. Fig.10 .

[0075] The second heat exchange module includes an annular fin tube heat exchanger 32, which is located inside the annular region formed by the annular column rod 35, and the first impeller 28 and the second impeller 29 are sleeved outside the annular column rod 35; the first impeller 28 faces downward, the second impeller 29 faces upward, and the annular discs fixed between the first impeller 28 and the second impeller 29 are spaced apart. When dispersing air outward at the same time, the first impeller 28 and the second impeller 29 rotate in opposite directions, and the anti-torque moment on the hanging bracket can be offset, and the dynamic stability of the entire hanging structure is improved.

[0076] A cylindrical second protective net 6 is arranged around the first impeller 28 and the second impeller 29 to prevent accidents caused by collision with people or foreign objects when the first impeller 28 and the second impeller 29 rotate. The dense mesh holes on the second protective net 6 play a role in dispersing the airflow. The tangential speeds of the first impeller 28 and the second impeller 29 are opposite, so that the airflow is radially dispersed. After a certain outflow distance, the airflows are mixed with each other, and the vortex formation is more complex, which is conducive to temperature homogenization.

[0077] When the first impeller 28 and the second impeller 29 rotate, the air is moved to flow radially from the center to the surroundings, with tangential velocity and radial velocity, and the air flow in each direction on the circumference is consistent. The airflow inside the first impeller 28 and the second impeller 29 and in the annular fins 43 also moves accordingly, and performs convection heat exchange with the metal surface. Then the heat of the refrigerant in the metal tube bundle is transferred to the heat of the indoor air, which has the effect of regulating the air state. The airflow generated by the first impeller 28 and the second impeller 29 continues to diffuse, reaches the indoor side wall, and then turns back to form a circumferential flow, and then sucks air from the center of the first impeller 28 and the second impeller 29 to complete the cycle. The path reference is Figure 2 The blowing distances from the first impeller 28 and the second impeller 29 to the side walls are the same, and the revolving flow formed from the cross section of the room is basically distributed symmetrically. The revolving flow in each direction circulates in the indoor space, and the overall distribution is relatively uniform, so the wind feeling and comfort are relatively uniform for the people inside.

[0078] Lamps can be added around the second protective net 6 to make the present invention function as a chandelier; patterns can also be added to function as interior decoration.

[0079] The wire harnesses of the first motor 27 and the second motor 30 are passed through the inner side of the ring column rod 35 , passed through the top of the hanging bracket, fastened against the inner top of the hanging bracket, and finally connected to the output end of the controller 4 .

[0080] The annular fin-tube heat exchanger 32 includes a plurality of annular fins 43 stacked in sequence vertically, second through tubes 45 equidistantly distributed in the circumferential direction of the annular fins 43 and folded up and down, a liquid distributor 38 connected to the liquid inlets of all the second through tubes 45 , and a collecting ring pipe 46 connected to the liquid outlets of all the second through tubes 45 .
