Detailed Implementation
[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the scope of protection of the present invention.
[0050] Please see Figures 1-12 This invention provides two technical solutions:
[0051] Example 1: An AI-based variable frequency solar heat pump air conditioning unit, comprising a variable frequency solar heat pump air conditioning unit consisting of an inclined plate solar collector 1, an outdoor unit 2, and an indoor unit 3. The inclined plate solar collector 1 is connected to a water storage tank 8 via pipes to store heated water. The outdoor unit 2 is equipped with a compressor 9 and a heat exchanger 10. The compressor 9, heat exchanger 10, and indoor unit 3 are connected in pairs via pipes, and each pipe is connected to a throttling valve 11. The heat exchanger 10 is externally equipped with a compensation mechanism to adapt to the temperature inside the heat exchanger 10 for auxiliary heating or heat dissipation. The compensation mechanism includes:
[0052] The transmission unit 4 includes a blow-and-suction integrated machine 41. A switching element 6 is connected to the port of the blow-and-suction integrated machine 41 via a left transmission pipe 42, and a square frame 44 is connected to the other port of the blow-and-suction integrated machine 41 via a right transmission pipe 43. An adjustment unit 7 is provided on the square frame 44 to enable the air nozzle 45 to be dynamically operated.
[0053] The moving part 5 is used to adjust the vertical position of the entire square frame 44;
[0054] Multiple temperature sensors are installed both inside and outside the heat exchanger 10 to collect temperature data, and the opening and closing of the transmission unit 4 and the moving unit 5 are controlled according to the changes in temperature data.
[0055] The inclined plate solar collector 1 provides a clean solar heat source for the unit. Its inclined installation increases the light-receiving area and heat collection efficiency. Connected to the water storage tank 8 via pipes, it converts absorbed solar radiation into heat energy, heating the water medium in the tank and storing the heat. The outdoor unit 2 is the core heat exchange chamber of the unit, housing the compressor 9, heat exchanger 10, throttle valve 11, and compensation mechanism. It provides installation space and protection for each component while ensuring adequate ventilation space to prevent internal heat buildup from affecting operating efficiency. The indoor unit 3 is placed in the indoor environment, exchanging heat with indoor air through refrigerant circulation to provide heating or cooling. Working in conjunction with the variable frequency heat pump and solar collector system, it regulates indoor temperature. Unit 9 is the core of the heat pump cycle, used to compress the refrigerant to increase its temperature and pressure, driving the refrigerant to circulate between the heat exchanger 10, the indoor air conditioner 3, and the throttling valve 11, ensuring continuous operation of the cooling or heating cycle. Multiple temperature sensors are installed inside and outside the heat exchanger 10 to collect temperature data. The temperature sensors transmit real-time data to the AI control unit, and automatically control the start, stop, and operation status of the transmission unit 4 and the moving unit 5 according to the changes in temperature data. The blow-and-suction integrated unit 41 has two working modes: forward blowing and reverse suction. When blowing forward, the hot air in the water tank 8 is delivered to the air nozzle 45 for defrosting. When suctioning in reverse, the hot air around the heat exchanger 10 is extracted to the outside to achieve rapid heat dissipation.
[0056] By installing temperature sensors inside and outside the heat exchanger 10 and using AI dual threshold and temperature range and delay judgment control logic, the internal temperature t1 and external temperature t2 are collected in real time to accurately identify frost and overheating states. Through the cooperation of inclined plate solar collector 1 and water storage tank 8, solar hot air is directly used for defrosting compensation, which solves the problems of traditional units being unable to adaptively control temperature, being prone to frost, and being prone to overheating. It realizes intelligent temperature compensation of heat exchanger 10, significantly improves heat exchange efficiency, and reduces energy consumption and failure rate.
[0057] Please see Figures 9-12 In this embodiment of the invention, the switching element 6 includes:
[0058] The conversion box 61 is connected to the left transmission pipe 42 on one side, and the opposite sides of the conversion box 61 are respectively connected to the air inlet pipe 62 and the exhaust pipe 63. The air inlet pipe 62 is connected to the top of the water storage tank 8, and the exhaust pipe 63 extends to the outside.
[0059] The intake pipe 62 and the exhaust pipe 63 are provided with opposite blocking parts 64 at the end face flow points of the conversion box 61.
[0060] The exhaust pipe 63 extends to the outside and is used to introduce outside cold air for heat dissipation or to expel internal hot air. The intake pipe 62 and the exhaust pipe 63 are respectively provided with a set of blocking components 64 at the end face of the conversion box 61. The opening and closing directions of the two sets of blocking components 64 are opposite to achieve unidirectional flow and reverse sealing to avoid mutual interference between hot air and cold air.
[0061] Please see Figures 11-12 In this embodiment of the invention, the barrier 64 includes:
[0062] The center rod 641 is rotatably installed at the end face of the intake pipe 62 or the exhaust pipe 63. Two rotating sleeves 642 are fitted on the upper and lower surfaces of the center rod 641. Symmetrical baffle plates 643 are installed on the outer sides of the upper and lower rotating sleeves 642 respectively. When the baffle plates 643 are not rotated, they seal the flow point of the intake pipe 62 or the exhaust pipe 63.
[0063] A reset member 644 is provided at the inner wall of the central rod 641 and the intake pipe 62 or the exhaust pipe 63 to keep the baffle plate 643 sealing the flow point of the intake pipe 62 or the exhaust pipe 63.
[0064] Limiting blocks 645 are installed on the inner walls of both the intake pipe 62 and the exhaust pipe 63. The limiting block 645 of the intake pipe 62 is located away from the pipe end face of the baffle plate 643, and the limiting block 645 of the exhaust pipe 63 is located near the pipe end face of the baffle plate 643.
[0065] Limiting blocks 645 are installed on the inner walls of both the intake pipe 62 and the exhaust pipe 63: the limiting block 645 of the intake pipe 62 is located on the side of the baffle plate 643 away from the pipe end face, restricting the baffle plate 643 to open only to the inside of the conversion box 61; the limiting block 645 of the exhaust pipe 63 is located on the side of the baffle plate 643 close to the pipe end face, restricting the baffle plate 643 to open only to the outside, thereby achieving the effect of one inlet and one outlet, and one-way interlocking air source switching.
[0066] By setting up the switching component 6, and utilizing the coordinated action of the conversion box 61, the air inlet pipe 62, the exhaust pipe 63, and the blocking component 64, the one-way automatic switching between hot air and cold air is realized. The defrosting compensation is achieved through solar-powered hot air, which solves the problem of mutual interference between defrosting or heat dissipation air sources and ensures a stable and reliable air source.
[0067] Please see Figure 12 In this embodiment of the invention, the reset member 644 includes a torsion spring 6441 sleeved on the end face of the central rod 641, and the intake pipe 62 and the exhaust pipe 63 are provided with a placement groove 6442 at the rotation point of the end face of the central rod 641, and the torsion spring 6441 is located in the placement groove 6442, and the extension end of the torsion spring 6441 is connected and fixed to the opposite side of the central rod 641 in the placement groove 6442.
[0068] Please see Figures 5-8 In this embodiment of the invention, the adjustment unit 7 includes:
[0069] The fixing plate 71 is centrally symmetrically installed on the top of the square frame 44, and the cylindrical tube 74 is moved by the pneumatic component 72 on the fixing plate 71.
[0070] The concave frame 75 is fixedly installed on the inner side of the square frame 44. The inner side of the concave frame 75 is rotatably installed on the outer arc surface of the air nozzle 45 through the rotating rod 76. The port of the air nozzle 45 is connected to the inner cavity of the square frame 44 through the hose 77 to realize gas transmission. The top of the rotating rod 76 is connected to the cylindrical tube 74 through the telescopic member 73, so that the cylindrical tube 74 moves while driving the rotating rod 76 to rotate.
[0071] Please see Figure 8 In this embodiment of the invention, the pneumatic component 72 includes a transverse cylinder 721 fixedly installed on the top of the fixed plate 71, and a transverse piston rod 722 is slidably connected inside the transverse cylinder 721, and the extended end of the transverse piston rod 722 is connected and fixed to the side of the cylindrical tube 74.
[0072] Please see Figure 8 In this embodiment of the invention, the telescopic member 73 includes a connecting rod 731 and a sliding rod 732. One end of the connecting rod 731 is rotatably connected to the bottom of the cylindrical tube 74, and one end of the sliding rod 732 is fixedly connected to the top of the rotating rod 76. One end of the sliding rod 732 extends through the interior of the connecting rod 731 and slides relative to the inner wall of the connecting rod 731. The sliding connection between the sliding rod 732 and the connecting rod 731 does not disengage.
[0073] Both the horizontal cylinder 721 and the vertical cylinder 52 are connected to the external air circuit, thereby increasing the driving force to complete the force-driven operation.
[0074] Please see Figure 7 In this embodiment of the invention, the moving part 5 includes an outer frame 51 fixedly installed in the inner cavity of the outdoor unit 2 of the air conditioner, and a vertical cylinder 52 is installed on the lower edge of the side of the outer frame 51. A vertical piston rod 53 is slidably installed inside the vertical cylinder 52. The top end of the vertical piston rod 53 is connected and fixed to the bottom side of the fixed plate 71 and drives the entire square frame 44 to move in the vertical direction. A sliding groove 54 adapted to the sliding of the fixed plate 71 is opened on the surface of the outer frame 51, and the sliding between the multiple fixed plates 71 and the sliding groove 54 keeps the square frame 44 horizontal.
[0075] The vertical cylinder 52 and vertical piston rod 53 of the moving part 5 drive the fixed plate 71 to rise and fall along the sliding groove 54 of the outer frame 51. In conjunction with the horizontal cylinder 721, telescopic part 73 and rotating rod 76 of the adjustment unit 7, the air nozzle 45 is driven to swing dynamically. This solves the problems of limited purging range, blind spots, fixed angle and low compensation efficiency. It realizes uniform defrosting and heat dissipation of the heat exchanger 10 at all heights, multiple angles and no dead angles, and greatly improves the temperature control compensation effect.
[0076] Example 2 differs from Example 1 in that it provides a control method for an AI-based variable frequency solar heat pump air conditioning unit, specifically including the following steps:
[0077] S1. Control the start-up and shutdown operations of various electrical equipment based on the needs of the air conditioning unit;
[0078] S2. The temperature inside and outside the heat exchanger 10 is determined by the AI detection module, and control commands are generated based on the temperature changes to realize the operation control of the compensation mechanism.
[0079] S3. The inclined plate solar collector 1 and the variable frequency heat pump are used in conjunction with the indoor and outdoor units of the air conditioner to complete the heating or cooling operation of the room.
[0080] In this invention, the operation in S2 of generating control commands based on temperature changes to control the operation of the compensation mechanism is as follows:
[0081] S21. Extract the internal temperature data t1 when the heat exchanger 10 is running, and extract the corresponding external temperature data t2 when the heat exchanger 10 is running. At the same time, determine the internal temperature data threshold T1 when frosting occurs and the internal temperature data threshold T2 when overheating occurs based on historical data.
[0082] S22. Determine the external temperature range [X, Y] of heat exchanger 10 based on the internal temperature data threshold T1 when frosting occurs, and determine the external temperature range [M, N] of heat exchanger 10 based on the internal temperature data threshold T2 when overheating occurs, and set a dual threshold rule to generate the instruction.
[0083] S23. The dual threshold rule is that when the external temperature of heat exchanger 10 belongs to the interval [X, Y] or the interval [M, N], and is within the interval for a duration of n, a control command is generated to realize the operation of the compensation mechanism and compensate the temperature inside heat exchanger 10.
[0084] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0085] During operation, the inclined plate solar collector 1 absorbs solar energy and transfers the heat to the water storage tank 8 for heat storage. The compressor 9 drives the refrigerant to circulate between the heat exchanger 10, the indoor air conditioner 3, the outdoor air conditioner 2, and the throttle valve 11, working in conjunction with the variable frequency heat pump to achieve indoor heating or cooling operation. Temperature sensors installed inside and outside the heat exchanger 10 collect internal temperature data t1 and external temperature data t2 in real time, and transmit the data to the AI control unit. The data is compared with the preset frosting temperature threshold T1, the overheating temperature threshold T2, and the corresponding external temperature ranges [X, Y] and [M, N]. When the temperature is within the threshold range and the duration reaches the set value n, a control command is immediately generated to activate the compensation mechanism to perform auxiliary heating defrosting or forced heat dissipation compensation on the heat exchanger 10.
[0086] When the blow-and-suction unit 41 is started, the airflow enters the conversion box 61 through the left transmission pipe 42. The air source path is switched through the switching component 6. In defrosting mode, the airflow pushes the baffle plate 643 at the air inlet pipe 62 to rotate around the central rod 61, and the air inlet pipe 62 is opened. The hot air in the water tank 8 enters the pipeline and is delivered to the square frame 44 from the right transmission pipe 43. In heat dissipation mode, the blow-and-suction unit 41 reverses its operation. The airflow is transmitted to the right transmission pipe 43 through the air nozzle 45 at the square frame 44 and enters the conversion box 61. At this time, the airflow pushes the baffle plate 643 at the exhaust pipe 63 to open and dissipate the hot air. The baffle plate 643 at the air inlet pipe 62 is kept closed under the action of the limit block 645 and the torsion spring 6441 to prevent the airflow from flowing back and realize the one-way automatic switching of the cold and hot sources.
[0087] The airflow is delivered to the square frame 44 via the right transmission pipe 43, and then sent to the nozzle 45 via the hose 77. The vertical cylinder 52 drives the vertical piston rod 53 to extend and retract, causing the fixed plate 71 to move vertically along the sliding groove 54 of the outer frame 51, so that the square frame 44 and the nozzle 45 rise and fall across the entire surface of the heat exchanger 10, achieving uniform blowing at all heights. At the same time, the horizontal cylinder 721 drives the horizontal piston rod 722 to move the cylindrical cylinder 74 laterally. Through the connecting rod 731 and sliding rod 732 of the telescopic component 73, the rotating rod 76 is driven to rotate around the concave frame 75, causing the nozzle 45 to dynamically adjust the blowing angle, expand the airflow coverage, and improve defrosting and heat dissipation efficiency.
[0088] Once the temperature of heat exchanger 10 returns to the normal range, the AI control unit issues a stop command, the blow-suction integrated machine 41 stops, the baffle plate 643 resets under the action of the torsion spring 6441, resealing the air inlet pipe 62 and the exhaust pipe 63, the moving part 5 and the regulating unit 7 reset, and the unit returns to the conventional variable frequency solar heat pump operating state, maintaining efficient, stable and energy-saving operation.
