Description

Technical Field

[0001] The present invention relates to the technical field of air-conditioning units, and in particular to a heat recovery and energy-saving device for an air-conditioning unit and a recovery method thereof. Background Art

[0002] As one of the indispensable devices in modern buildings, the air-conditioning unit undertakes the important task of regulating indoor temperature, humidity and air quality. With the progress of technology and the improvement of people's requirements for the quality of life, the technology of the air-conditioning unit is constantly developing and innovating. At present, in order to recover the heat generated by the air duct, a heat recovery and energy-saving device is required.

[0003] For example, a Chinese patent with the publication number CN221882261U discloses a heat recovery and energy-saving device for an air-conditioning unit, which includes a sleeve frame. Both the upper and lower sides inside the sleeve frame are fixedly connected with bases. One side of the base is fixedly connected with a sleeve ring, and a heating pipe is fixedly connected inside the sleeve ring. Two adapter pipes are fixedly connected between the heating pipes. One side of each adapter pipe is fixedly connected with a diversion pipe. The side wall of the sleeve frame is fixedly connected with an adapter piece, and a screw rod is movably connected inside the adapter piece through a limit hole.

[0004] The above-mentioned disclosed patent can effectively recover the heat generated during the operation of the air-conditioning unit, reduce the waste of heat, and improve the energy-saving effect of the air-conditioning unit. However, there are still some defects in this heat recovery and energy-saving device that need to be improved. Specifically, the hot air conveyed by the air duct is used to blow and heat the surface of the heating pipe, and then the water in the heating pipe is heated. However, the contact area between this heating pipe and the hot air is limited, resulting in low heat transfer efficiency. When the hot air blows on the surface of the heating pipe, there may be an uneven flow field, resulting in inconsistent heating effects. The water flow in the heating pipe may not be sufficient, affecting the heat transfer and the heating rate of the water. Therefore, improvement is needed. Summary of the Invention

[0013] A recovery method for a heat recovery and energy-saving device of an air-conditioning unit includes the following usage steps:

[0014] Step 1: Check whether all components are in good condition, especially the deflector, heating pipe, air flow sensor, temperature and humidity sensor, etc. Dock the connection frame with the air outlet pipe of the air-conditioning unit and detect whether the docking is tight. Then fix the connection frame on the air outlet pipe through the fixing mechanism to prevent the heat recovery and energy-saving device from falling, and complete the installation of the heat recovery and energy-saving device.

[0015] Step 2: Monitor the data of the temperature and humidity sensor and the air flow sensor through the control panel to ensure the normal operation of the device. Use the adjustment mechanism to adjust the angle of the deflector to optimize the flow field distribution of the hot air on the surface of the heating pipe.

[0016] Step 3: After the air-conditioning unit works, the hot air is discharged through the air duct and is guided to the surface of the heating pipe through the deflector in the connection frame. The deflector can ensure that the hot air can evenly blow the heating pipe.

[0017] Step 4: The hot air exchanges heat with the heat conduction component on the outer surface of the heating pipe to increase the heat transfer area and effectively transfer the heat into the heating pipe.

[0018] Step 5: After the heat is transferred into the heating pipe, the spiral groove and the flow disturbing piece design inside the heating pipe enhance the turbulence degree of the water, improve the contact area between the water and the inner wall of the heating pipe, and thus accelerate the heating speed of the water.

[0019] Step 6: During the operation of the device, the control panel records each parameter setting, energy consumption and other data, regularly analyzes the data, and evaluates the performance of the heat recovery and energy-saving device. Based on the analysis results, it provides a basis for subsequent optimization and improvement to ensure the continuous and efficient operation of the device.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] First, in the present invention, by installing heat-conducting fins on the outer surface of the heating tube, opening a plurality of heat-conducting holes in the heat-conducting fins, installing a heat-conducting column in each heat-conducting hole, and fixing a heat-conducting side piece between the heat-conducting column and the heat-conducting hole, this structural design can increase the contact area between the heating tube and the hot air, improve the heat transfer efficiency, enable the hot air to blow more evenly on the surface of the heating tube, and improve the consistency of the heating effect. A spiral groove is opened inside the heating tube, and a plurality of spoilers are fixed at the spiral groove to increase the flow path and turbulence of water in the heating tube, so that the water can more fully absorb the heat transferred by the heating tube.

[0022] Secondly, in the present invention, a connecting frame is installed on the installation frame, and multiple guide plates are installed in the connecting frame. The guide plates can guide the hot air to flow more smoothly through the surface of the heating tube, thereby improving the heat transfer efficiency. When the airflow in the air duct is unevenly distributed, the guide plates can balance the airflow, so that the airflow enters the heating tube more evenly, thereby improving the heating efficiency. If the airflow is too large, the heating tube may not be able to fully heat the airflow, resulting in energy waste. The first power component is used to drive the transmission plate to move, so that the transmission plate drives multiple transmission racks to move, and the transmission rack pushes the gear to rotate, so that the transmission gear drives the transmission rod to rotate, and the transmission rod drives the guide plate to rotate to adjust the angle of the guide plate. By adjusting the size of the guide plate opening, the amount of airflow entering the heating tube can be controlled, thereby avoiding energy waste and ensuring the stable operation of the heat recovery and energy-saving device.

[0040] A recovery method for a heat recovery and energy saving device of an air conditioner unit includes the following usage steps:

[0041] Step 1: Check whether all components are in good condition, especially the deflector 7, heating tube 2, air flow sensor 601, temperature and humidity sensor 602, etc. Connect the connection frame 6 to the air outlet pipe of the empty unit, and check whether the connection is tight. Then fix the connection frame 6 on the air outlet pipe through the fixing mechanism 10 to prevent the heat recovery energy-saving device from falling, and complete the installation of the heat recovery energy-saving device;

[0042] Step 2: Monitor the data of the temperature and humidity sensor 602 and the air flow sensor 601 through the control panel 12 to ensure the normal operation of the device, and use the adjustment mechanism 8 to adjust the angle of the deflector 7 to optimize the flow field distribution of the hot air on the surface of the heating tube 2;

[0043] Step 3: After the air conditioner unit works, the hot air is discharged through the air duct and is guided to the surface of the heating tube 2 by the deflector 7 in the connection frame 6. The deflector 7 ensures that the hot air can evenly blow on the heating tube 2;

[0044] Step 4: The hot air exchanges heat with the heat conduction component 3 on the outer surface of the heating tube 2 to increase the heat transfer area and effectively transfer the heat into the heating tube 2;

[0045] Step 5: After the heat is transferred into the heating tube 2, the spiral grooves 4 and turbulators 5 inside the heating tube 2 are designed to enhance the turbulence degree of the water, so as to increase the contact area between the water and the inner wall of the heating tube 2, thereby accelerating the water heating speed;

[0046] Step 6: During the operation of the device, the control panel 12 records data such as each parameter setting and energy consumption, analyzes the data regularly, evaluates the performance of the heat recovery energy-saving device, and provides a basis for subsequent optimization and improvement according to the analysis results to ensure the continuous and efficient operation of the device.

[0047] The working principle of the present invention is as follows: Fix the docking frame 9 on the air outlet pipe of the air conditioner unit through screws. Then move the main body of the device so that the slider 102 on the connection frame 6 aligns with the sliding groove 101 of the docking frame 9, and connect the slider 102 with the sliding groove 101 to complete the preliminary installation of the main body of the device. Then rotate the torsion wheel 1052 to drive the first shaft rod 1051 to rotate. The first shaft rod 1051 drives the first tooth cone 1053 to rotate. The first tooth cone 1053 drives the second tooth cone 1054 to rotate. The second tooth cone 1054 drives the second shaft rod 1055 to rotate. The second shaft rod 1055 drives two first lead screws 855 to rotate. At this time, the nut 1054 on the surface of the first lead screw 855 moves, so that the nut 1054 drives the fixing rod 103 to move, and the fixing rod 103 is inserted into the fixing hole 104 to fix the slider 102 with the sliding groove 101, thereby fixing the main body of the device on the air outlet pipe of the air conditioner unit. The hot air generated by the air conditioner unit is discharged into the installation frame 1 through the air outlet pipe. The guide plate 7 guides the hot air to flow more smoothly over the surface of the heating pipe 2, improving the heat transfer efficiency. The temperature of the hot air is monitored by the temperature and humidity sensor 602, and the air flow in the air duct is detected by the air flow sensor 601. When the air flow is unevenly distributed, the guide plate 7 can play a role in balancing the air flow, making the air flow enter the heating pipe 2 more evenly and improving the heating efficiency. When the air flow is too large, the heating pipe 2 may not be able to fully heat the air flow, resulting in energy waste. At this time, the motor 852 drives the first gear 853 to rotate. The first gear 853 drives the second gear 854 to rotate. The second gear 854 drives the first lead screw 855 to rotate, so that the guide block 8561 connected to the nut seat 856 slides inside the limit frame 8562 and stably moves under the action of the guide rod 8563 in the limit frame 8562. Thus, the nut seat 856 stably drives the transmission plate 84 to move. The transmission plate 84 pushes the transmission rack 83 to move. The transmission rack 83 drives a plurality of transmission gears 82 to rotate. The transmission gears 82 drive the transmission rod 81 to rotate. The guide plate 7 is driven by the transmission rod 81 to rotate to adjust its working angle. By adjusting the opening size of the guide plate 7, the air flow rate entering the heating pipe 2 can be controlled to avoid energy waste. The hot air enters the installation frame 1 and contacts the heating pipe 2. The heat conducting fins 31 on the outer surface of the heating pipe 2 increase the heat transfer area, and further increase the heat transfer area through the heat conducting holes 32, heat conducting columns 33 and heat conducting fins 31 inside it, improving the heat transfer efficiency, enabling the hot air to blow more evenly over the surface of the heating pipe 2, improving the consistency of the heating effect, and facilitating the uniform heating of the cold water inside the heating pipe 2. A spiral groove 4 is opened inside the heating pipe 2, and a plurality of flow disturbing pieces 5 are fixed at the spiral groove 4, increasing the flow path and turbulence degree of the cold water inside the heating pipe 2, so that the cold water can absorb the heat transferred by the heating pipe 2 more fully. When maintenance of the heat recovery and energy saving device is required, the fixing mechanism 10 is used to disconnect the connection and fixation between the slider 102 and the sliding groove 101 of the docking frame 9, and then the heat recovery and energy saving device can be removed for maintenance, improving the convenience during maintenance.
